Safety Instruction1-2


Using Hotmelt

Temperature

The temperature must not exceed or fall below the specified temperatureranges; continuous temperature monitoring is appropriate. Excessively hightemperatures may give rise to odours and impair the quality of the hotmelt.Excessively low temperatures also have negative effects. Shouldsatisfactory results be achieved only at a temperature other than thespecified application temperature, please be sure to contact us.

Glue Tank

Do not leave the glue tank in heated state for a prolonged period withoutremoving the adhesive (thermal damage to the hotmelt).

When the machine is to remain out of operation for a prolonged period, theheating should be shut down or the temperature lowered. Glue tanks mustbe covered, in order to prevent contamination with paper dust, moisture anddirt.

We recommend regular cleaning of the melting and applicationsystems.

Should you have any doubts or experience any difficulties when using thehotmelt, please call us: We want to help before any damage occurs.

Caution -- Danger of Injury

Protect the operating personnel against burns when handling hotmelts in hotstate. Unfortunately, injuries occur when precautionary measures areignored. Protective gloves are to be worn.

Medical advice when hotmelt in hot state has come into contact withthe skin:

� Cool burn immediately with clean and cold water.

� Do not remove hotmelt residues from the skin.

� Cover burn with clean and moist compresses and consult a doctor

immediately.

Hotmelt adhesives also give off fumes at the specified applicationtemperature. This often gives rise to unpleasant smells.

In case of temperatures substantially below the specified applicationtemperatures, there is a danger that harmful decomposition products mayform.

Measures to remove the fumes via appropriate extraction areimperative.

Safety Instruction 1-3


Information Leaflet on the Use of PUR--HotmeltsWhen working with PUR--hotmelts, there are some special productcharacteristics to be taken into account in order to guarantee a smooth andproblem--free operation of your melting unit.

PUR--hotmelts are characterised by the fact that after the purely physicalsetting where the material solidifies, a subsequent reaction with humidityoccurs which triggers chemical crosslinking. This phenomenon is alsocaused by processing the material at too high temperatures and / or bythermal strain over too long a period of time. In order to avoid or at least tolimit these increases in viscosity, we recommend the following measures:

� PUR--hotmelts must always and by all means be protected against

humidity (ambient air) whether during production, storing or use.

� Never process PUR--hotmelts at higher temperatures than

recommended!

� Prevent local over--heating.

� When changing to a different type of adhesive, do check whether the

products are compatible. Contact your adhesive supplier for furtherinformation. Otherwise there may be a chemical reaction which results inan unmeltable compound!

� Completely use up the molten material within about 4 hours!

Always contact your adhesive supplier / producer and observe strictly theinstructions and information given in the material safety data sheet!

Our machines are very well apt for the processing of PUR--hotmelts.However, please take into account that there are some special features tobe observed when it comes to the use and maintenance of your meltingunit:

� When processing the glue in tank melting units, you need a constant gas

injection on the molten material with dry inert gas in order avoidchemical reactions with the ambient air (humidity).

� All melting units and application equipment (like coating heads, nozzles,

hoses, etc. ) have to be cleaned and / or flushed thoroughly in case of amachine standstill / production break or when changing to a differenttype of adhesive. The remnants of the flushing agent have to beexpelled completely from the system before restarting the machine.

When processing reactive hotmelts your adhesive supplier or our companyshall be glad to advise you. When observing the hints given above, youshould have no problems working with PUR--hotmelts. However, we are notin a position to enter into a warranty or give guarantees in case ofunprofessional use of this sensitive material or the non--observance of therecommendations given either above or by your adhesive supplier.

Using Hotmelt

Temperature

The temperature must not exceed or fall below the specified temperatureranges; continuous temperature monitoring is appropriate. Excessively hightemperatures may give rise to odours and impair the quality of the hotmelt.

Excessively low temperatures also have negative effects. Shouldsatisfactory results be achieved only at a temperature other than thespecified application temperature, please be sure to contact us.

Glue Tank

Do not leave the glue tank in heated state for a prolonged period withoutremoving the adhesive (thermal damage to the hotmelt).

When the machine is to remain out of operation for a prolonged period, theheating should be shut down or the temperature lowered. Glue tanks mustbe covered, in order to prevent contamination with paper dust, moisture anddirt.

We recommend regular cleaning of the melting and applicationsystems.

Should you have any doubts or experience any difficulties when using thehotmelt, please call us: We want to help before any damage occurs.

Caution -- Danger of Injury

Protect the operating personnel against burns when handling hotmelts in hotstate. Unfortunately, injuries occur when precautionary measures areignored. Protective gloves are to be worn.

Medical advice when hotmelt in hot state has come into contact withthe skin:

� Cool burn immediately with clean and cold water.

� Do not remove hotmelt residues from the skin.

� Cover burn with clean and moist compresses and consult a doctorimmediately.

Hotmelt adhesives also give off fumes at the specified applicationtemperature. This often gives rise to unpleasant smells.

In case of temperatures substantially below the specified applicationtemperatures, there is a danger that harmful decomposition products mayform.

Measures to remove the fumes via appropriate extraction areimperative.



Information Leaflet on the Use of PUR--HotmeltsWhen working with PUR--hotmelts, there are some special productcharacteristics to be taken into account in order to guarantee a smooth andproblem--free operation of your melting unit.

PUR--hotmelts are characterised by the fact that after the purely physicalsetting where the material solidifies, a subsequent reaction with humidityoccurs which triggers chemical crosslinking. This phenomenon is alsocaused by processing the material at too high temperatures and / or bythermal strain over a too long a period of time. In order to avoid or at least tolimit these increases in viscosity, we recommend the following measures:

� PUR--hotmelts must always and by all means be protected againsthumidity (ambient air) whether during production, storing or use.

� Never process PUR--hotmelts at higher temperatures thanrecommended!

� Prevent local over--heating.

� When changing to a different type of adhesive, do check whether theproducts are compatible. Contact your adhesive supplier for furtherinformation. Otherwise there may be a chemical reaction which results inan unmeltable compound!

� Completely use up the molten material within about 4 hours!

Always contact your adhesive supplier / producer and observe strictly theinstructions and information given in the material safety data sheet!

Our machines are very well apt for the processing of PUR--hotmelts.However, please take into account that there are some special features tobe observed when it comes to the use and maintenance of your meltingunit:

� When processing the glue in tank melting units, you need a constant gasinjection on the molten material with dry inert gas in order avoidchemical reactions with the ambient air (humidity).

� All melting units and application equipment (like coating heads, nozzles,hoses, etc. ) have to be cleaned and / or flushed thoroughly in case of amachine standstill / production break or when changing to a differenttype of adhesive. The remnants of the flushing agent have to beexpelled completely from the system before restarting the machine.

When processing reactive hotmelts your adhesive supplier or our companyshall be glad to advise you. When observing the hints given above, youshould have no problems working with PUR--hotmelts. However, we are notin a position to enter into a warranty or give guarantees in case ofunprofessional use of this sensitive material or the non--observance of therecommendations given either above or by your adhesive supplier.



VDK--MIDI Volume Dosing Head

Capabilities

The VDK--MIDI volume dosing head discharges adhesive beads inthicknesses that must be precisely controlled during application -- a featurethat is imperative with robots. This is achieved by varying the travellingspeed, e.g. when changing directions or travelling through corners so thatthe amount of applied adhesive is instantly adjusted accordingly. This ispossible because the pump is mounted directly on the head, therebyeliminating a long hose and the associated delay in adhesive discharge,namely the time it takes for the adhesive to pass through the hose from theconveying pump in the tank to the application head.

Equipment

The volume dosing head is fitted with a gear pump from the 2.4 type series.

The nozzle size depends on the given requirements. Special nozzles areavailable upon request.

Mounting

Mounting is by way of the holder on the head. Multi--point fastening ensuresthat mount oscillations are at an absolute minimum. Hose connection isbeing realised by means of fixed hose screw connections or a swivel joint( heated / unheated ). Other adapters are available upon request.

A compressed--air connection is necessary to operate the discharge head.The special membrane--piston concept eliminates the need to lubricate theair with oil.

The electrical connections for the control system are easily established byway of standard connectors.

Setting into operation

The head must only be opened after the heating--up processes have beencompleted. With the corres--ponding pressure (from the tank unit) and arunning head pump the adhesive is discharged out of the nozzle. Theamount of discharged adhesive can be slightly throttled by adjusting thestroke of the nozzle needle. However, this must not be used to diminish theamount of discharged adhesive as this is controlled by the pump. Strokeadjustment merely influences the discharge behaviour of the adhesive sothat a positive effect can be achieved regarding the application pattern inkeeping with numerous framework parameters.

WARNING: The heated part of the discharge head can cause seriousburns! Never reach into the rotating parts when the pump is running!Always observe the safety rules regarding the use of hot media and whenrotating shafts are involved!



Technical DataNOTE: An uninterrupted supply of compressed air is absolutely imperativefor the functioning of the equipment. The closing and opening pressures arebeing generated by pneumatic systems. A failure in the compressed airsupply is sure to cause a break down of the coating heads and maysubsequently danage the modules.

Safety instruction:The compressed--air supply must be maintained in the event of ”EmergencyOFF” as, otherwise, there may be uncontrolled adhesive discharge.

E 2010 Gear pump

Safety InformationWARNING: Bitte befolgen Sie die als separates Dokument beigefügtenSicherheitshinweise und die spezifischen Sicherheitshinweise in dergesamten Dokumentation.

WARNING: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

PrefaceGear pumps are precision--made pumps with an extremely wear resistanceand delivery accuracy.

The gear pumps are made for deliver mediums with further agreedproperties and performance characteristics.

Gear pumps with drive units for many kinds of use in cooperation andarrange to the requirements of the customer.

In order to guarantee this high accuracy of delivery, gear pumps have onlysmall tolerances. This high manufacturing precision must not be impaired byimproper handling, i.e. when disassembling, cleaning and mounting.

We therefore want to give some instructions for the correct handling of gearpumps.

The enclosed drawing shows a gear pump in assembled state. The gearpump consists of only a few absolutely necessary parts, which arecompletely interchangeable between pumps of the same type, because ofthe high manufacturing precision. Therefore cleaning and replacement ofparts is more simplified and allows an economical storage of spare--parts.

General safety instructionsS These safety instructions are not exhaustive. If you have questions, or

problems, please contact the manufacturer. At the time of delivery thegear pump correspond to the level of technology and are regarded assafe to operate.

S Owing to the functioning of the gear pump, uncontrolled operation canlead to suction and delivery pressures that damage the pump orinstallation and endanger the personnel. It is therefore mandatory thatpressure--control devices including limit switches be installed at the inletand outlet.

S The pump is lubricated by the medium pumped. Dry runs must beavoided at all costs, because it is possible that the pump could bedamaged.

S A too high driving torque can damage the pump. Use a suitable safetydevice such an overload coupling. For the maximum allowed torque,consult the pump specifications.

S Please observe when handling with pump or flushing medium or oil, thatgreases and other chemical substances follow the the safety regulationsthat apply to the product concerned.

S Always use the personal safety equipment made available to you, suchas protective glasses, ear protection, safety helmet, safety gloves andprotective clothing.

S Depending on the heating system, be careful when handling hotoperating substances.

S If the gear pump is passed on to a another party, the operating manualmust be transferred to the new owner.

S Perform maintenance work at on gear pump only while the drive--unit isshut down. Do not start working until all of rotating parts have come to acomplete standstill. Secure the drive--unit against accidental restart.Only operate drive--unit and pump when all safety devices are in placeand operative. Do not remove these protective devices or safetyequipment.

S The A--weighted acoustic power level of the pump is 70 dB (A). Thenoise is basically dependent on the revolution speed and the deliveredmedium.

E 2010 Gear pump

Operation of new pumpsPumps are supplied in oiled condition in order to protect them againstcorrosion. To avoid dry run of the rotating parts during the start--up to thepoint where the self--lubricating polymer provides the necessary lubrication,driving arbor, stud and gears should be oiled by a few dropsof hightemperature resistant silicon oil (f.i. AP 500 stab Messrs. Wacker--Chemie,Munich/Germany).

After starting, the pump should operate as soon as possible with polymer. Ifthe pump cannot be turned before working, it is recommendable todisassemble the pump and to clean it carefully from any pollution.

Before mounting all parts must be completely clean and dry. Whenmounting, apply again some drops of silicon oil to the a/m. parts.It is very important for the precision function that the surface of the spinninghead are clean and plain.

We recommend:

Flatness appr. 2μm

Surface roughnes Ra=0,2μm (Rt=1μm)

If the surface of the spinning head is not plain enough, the pump can bedistorted when screwing, or the metallic sealing between pump and thesurface of the spinning head can no longer be guaranteed.

Before start--up make sure, that the pump is sufficiently filled with polymer!

In order to have a pump exchanged very quickly and have only small lossproduction, it is recommendable to heat the pumps in an electric oven up tooperating temperature. With this method the pump has nearly the sametemperature as the spinning head when mounting. The polymer does notfreeze and can be delivered easily.

After mounting, check the easy running of the pump.

When driveing the pumps with extended shaft, the following points have tobe observed:

1. coupling has to balance eccentricity and deviation in angle,

2. if possible apply universal shaft with length compensator,

3. avoid axial and radial pressure on driving arbor of the pump.

6 Type 1,75

E 2010Gear pump

Alignment of the driving shaft and motor unitA major influence on the leakage at the pump head and also on the life timeof the gear pumps is the accurate alignment of the gear motor unit. Everygear motor unit must be perfectly aligned with a suitable alignment deviceprior to the mounting of the gear pumps.

Alignment must be carried out when the beam is heated up to normaloperation temperature!

When aligning, the following values must not be exceeded:

S Angular deviation of the driving shaft of ± 0,1° (approx. 1,75 mm lateraldeviation per 1000 mm)

S Radial displacement of 0,2--0,4 mm of the driving shaft away from thecentre of the drive plug or the extended shaft of the pump.

S Parallelism of the the motor unit towards the clamping surface up to0,25mm.

S A displacement of the driving shaft of 2 mm away from the slot end ofthe drive plug or at the end of the driving arbor should be strived for.This ensures that no axial force is applied to the drive plug or drivingarbor through the driving shaft, and that the drive tang is simultaneouslysufficiently deep embedded in the drive plug for efficient transfer of thedrive torque.

Type 1,75 7

E 2010 Gear pump

Mounting of gear pumps

S Before the gear pumps are installed, all lines should be rinsed byflushing with Polymer or a similar medium. For flushing the lines use aflushing--plate instead of the pumps.

S Cylindrical screws used for mounting of the gear pumps must be of thestrength class 10.9 or 12.9. The thread of the screws should be coatedwith a temperature stable lubricating medium prior to mounting.(recommandation: OKS 240, Antiseize paste / Copper paste)

S Heat up the pumps before mounting (pre--heating up to approximatelythe operating temperature).

S Tighten the mounting screws cross--wise. For the drive torques see “BoltTightening Torque” table in the operation manuals of the relevantpumps. Use a torque wrench! Check the smooth rotation of the pumpsafter mounting has been completed!

S Pump heat insulation to be mounted over the pumps.

The gear pump should be protected from overloading with a suitable safetydevice (shear pin) allowing a maximum of 90% of the permitted drive torque(see respective gear pump specification).

Starting up of the plantThe temperature of the gear pumps must be that of the required standardoperating temperature before they are put into operation. The starting upprocedure should be according to recommendations as follows:

S Before installing the gear pumps, all lines must be cleaned by flushingwith Polymer or similar. For flushing the lines use a flushing--plateinstead of the pumps.

S Start up of the unit with disengaged pumps until the pre--pressure of thegear pumps is approx. 20 -- 50 bar.

S In many cases, the pumps may start running already shortly afterstarting the extruder. If all gear pumps are rotating slowly on their own,skip the next two positions and start up.

S If the gear pumps are not running, shut down the unit and hold thecomplete system at the normal operating temperature for a period of 2 –3 hours. During this period, a temperature equalisation will be attainedbetween the beam and the pumps.

S After this time period, start the unit until the designated pre--pressure isreached. With the help of the pre--pressure the disengaged gear pumpswill start to rotate slowly on their own.

S Connect the driving shafts to the pumps and start up the motor units.

8 Type 1,75

E 2010Gear pump

Exchange of gear pumps during operation

S Shut down the gear motors of the pumps to be changed, freeze thepolymer in the beam.

S Withdraw the driving shaft from the pump.

S Remove the insulation.

S Unscrew the bolts holding the pump and remove the pump from thebeam.

S Take the new pump out of the heating oven (oven temperature approx.20° above the Polymere operating temperature).

S Prior to mounting of the new pump, make sure that the pump rotatessmoothly and that it has been pre--oiled with silicone oil.

S Mount the pump on the beam and open the freezing valve. After a shorttime, the disengaged pump will be rotating slowly on its own. Thestarting up of each new pump should be executed as described in ,“Starting up of the plant”.

E 2010Gear pump

Cleaning of the gear pumpsFor the metering accuracy and life--time of gear--pumps a skillful cleaningafter operation is of great importance.

For cleaning the complete pump by flushing use a detergent withself--lubrication properties (e.g. oil).

Don’t use water or solvent without lubrication properties, because thelubrication of the bearing points must be done by the cleaning fluid.

If a cleaning among heating treatment is required, it is possible to heat upthe complete pumps without the sealing, above the melting point.

For the maximum temperature, consult the pump specifications!

Cool off the parts at room temperature after cleaning. The heated partsshould not be placed on cold surfaces.

For disassembling the pumps are to be clamped into a bench vice and thesingle parts of the pump are to be put into a perforated metal box.

Now the cleaning of the single parts from the still adherent melt can be doneby washing in gasoline.

After cleaning, the single parts must be checked for flutes, breaking ofedges of bores and gears etc.. If necessary, damaged parts can berefinished by lapping or can be exchanged against new parts.

In case the cleaned single parts are not assembled again, they must bekept dry in order to protect them against corrosion and oiled with means ofpreservation.

Fitting packingsClean the stuffing box thoroughly before inserting the packing rings. Careshould be taken to see that the working surfaces are perfectly smooth (noscores). An surface defects should in priniple not be greater, if this ispossible, than Ra 0,50µm.

Insert the finished rings one after the other into the seal chamber withstaggered cut ends and tightem them by means of the stuffing pressureflange or the press screw.

Tightem the stuffing pressure flange or the press scew so that the packing isadapted to the stuffing box. Then loosen the nuts and tightem them oncemore.

Installing of the packing rings:that the sealing properties are not affected due to unnecessary folding ofcross section. If the rings cannot be inserted from the frontside, the endsshould be folded back along the shaft until they slide over it. Seperating ofthe rings in radial direction should be as little as possible. Installing byinserting the cut ends (see fig. Below)--

When the pump is running, tightem the nuts carefully (1/8 or 1/4 of a turneach time) and reduce leaks to the necessary minimum.

Proper adjustment of the packing and correct setting of the temperature ofthe stuffing box are the determining factors in the packings working life.Care taken at the start will be amply repair by the pumps workingtrouble--free, time saved on maintenance, equipment protection, and bymade in packing costs.
