Increase productivity —

f With 448 spinning positions, the longest rotor spinning machine of its class

f Up to 13% more yarn

f Fastest piecing technology with Joint Spinning In synchronous piecing

BD 448BD 448 7

Automatically more profitable

More spinning positions per square metreBenefit from the BD 448’s top-notch productivity: maximum take-up speeds of 165 m/min at each of its 448 spinning positions. Thanks to a particularly compact spinning position design, you produce yarn on the largest number of spinning positions per square metre, making best use of the space available.

Run-up: 90 % fasterNo other rotor spinning machine of its class runs up faster than the BD 448 with Joint Spinning In technology (JSI). Compared to conventional piecing employing two operators, you are less dependent on personnel with the BD 448 be-cause Joint Spinning In operates automatically. Digitally controlled synchronous piecing at all 448 spinning positions guarantees you piecing reliabil-ity of 95 percent. This means: even with 448 spinning positions, the machine runs up in less than 10 minutes. Thanks to JSI your machine reaches its full output power – e.g. following a power failure – 90 percent faster.

Energy budget improved

Innovative detailed solutions save up to 10 % of energyThe suction system and the rotor drive consume the most energy in a rotor spinning machine. That is why Schlafhorst has developed new, more efficient design solutions for this purpose. The result: with smartly improved drive and control technology the BD 448 reduces its energy consumption by up to 10 % compared to older BD genera-tions.

Vacuum-optimised spinboxThe rotor housing was equipped with even more effective sealing. Fluctuations and leakages in vacuum are prevented even more consistently.

EVA – better than everEven EVA, the economical, electronically con-trolled vacuum system, was further improved: thanks to automatic sieve cleaning which is also controlled electronically, the system has to adjust the vacuum less frequently. A remedy that contrib-utes to additional energy savings.

This is how you reduce your spinning costs

Reduce your staff requirementsThe longer the machine is, the more efficiently you can deploy your staff. Key areas of activity like the removal section or the suction system “operate” up to 448 spinning positions on the BD 448. The operating cost per spinning position is reduced as a result. From the length point of view alone, you can cut staff costs by up to 7 % as compared to a machine with 416 spinning positions, for in-stance.

Saving time – planning betterThe new design of the BD 448 makes operation and maintenance for your staff as easy as pos-sible. All BD 448 control elements are conspicu-ously designed in yellow and thus are easily iden-tifiable at first sight – for fast action. Even the spinning components can be easily accessed and replaced very quickly. Your advantage: downtimes are reduced, the machine’s capacity utilisation is optimised. And your staff can oper-ate more spinning positions.

Service more rapidly, clean less frequently

Halve the amount of work involved in cleaningThe staff expenditure for cleaning the sieve in the suction system section is often considerable. De-pending on raw material and yarn, around 750 man-hours can accrue here per machine and year. Not so in the case of the BD 448. An integrat-ed slider removes accumulations of dirt from the sieve automatically and regularly. The machine operator then only has to remove the dirt from the collecting container instead of cleaning the sieve manually as before. The amount of work in cleaning the sieve is thus reduced by half.

Automatic sieve cleaning

Fast action, more productionIf a spinning position is not producing, it is important to find the cause right away. With optical and acoustic signals, the BD 448 provides active operator support to help find the causes of produc-tion interruptions quickly and thus facilitate more production.

The new central indicator light and an alarm tone indicate neces-sary actions prominently and precisely, for instance, that the filter chambers have to be cleaned or the package removal conveyor belt is full. LEDs visible over a long distance indicate full packages or yarn breaks. This is very helpful, particularly on long machines.

High speed and new functionsThe new generation of BD 448 software is meas-urably faster and higher performing. Because time is money – with the BD 448 you have everything in view more quickly and are optimising while in full operation. The BD 448 display now even shows specific information for each spinning position – e.g. for package change or for spinning position efficiency so that the spinning process and the machine’s productivity can be optimised further.

Quick lot change while the machine is runningThe Intelligent Drive System (IDS) makes you faster and more inde-pendent. Common default settings for diverse raw materials and yarn counts make lot changes quick and easy. All settings are centrally configured on the input display, from the speed of the opening rollers and rotors through draft and yarn twist right up to spinning vacuum and trash suction. Changes in yarn count no longer require the change gears to be replaced. Your employees get all the settings and information with just three clicks. Easy-to-understand pictograms make the menu guide exception-ally speedy.

Packages to order in every count range

The only one in its segment up to Ne 1 (Nm 1.7)The BD 448 supports all yarn counts – and as a result, opens up totally new options for you with regard to flexibility. It is the only machine in its seg-ment that enables you to produce even coarse yarns up to Ne 1 (Nm 1.7) in proven and tested quality.

And you don’t have to modify anything, instead just implement a normal lot change and insert a few parts and spinning components that are geared to coarse yarn requirements into the ma-chine.

Software-controlled yarn guide All counts

Improved packages – at the touch of a buttonWith E-cam, the electronically controlled yarn guide, you produce custom packages at the touch of a button. Because now you con-figure the yarn guide’s settings which are crucial to quality on the central BD 448 control panel. As of now you control the angle of wind, anti-patterning, package traverse and take-up tension centrally. E-cam thus provides you with maximum performance and preci-sion. An additional guarantor of quality is the winding head with op-timised damping. It improves the package density and in doing so makes the BD 448 ideal for viscose yarns and yarns made of man-made fibres too.

Trend-setting technologies for greater quality

Aerodynamically optimised spinboxThe improved spinbox NSB 38 was equipped with a new, optimised seal. It guarantees a con-stant spinning vacuum from the first to the 448th spinbox. All air-ducting components are designed to ensure optimal fibre orientation and quality. Centrifugal force and air flow collaborate optim-ally. Moreover, the BD 448’s air utilisation as a whole is controlled electronically with the aid of EVA. The result: you get consistently good yarn values with high spinning stability and productivity – even when spinning raw materials that are more difficult to process, e.g. extremely short-staple cotton grades or low-grade noils.

Latest generation piecing technologyPiecing with the BD 448 – this is synonymous with a high success rate with high reproducibility, even for wool and wool-like fibres. Burmaster BM 2+ with digitally controlled SDSI technology (Single Drive Sliver Intake Technology) sees to this. The design and surface geometry of the ceramic sliver feed were optimised once again. In this way, an even better sliver feed was achieved – for even better piecings. And this without any compressed-air requirement whatso-ever!

Leading spinbox technology Optimised piecing

Quality guarantor with triple effectWith Corolab Q you have one of the best quality guards on board that the market has to offer. Its efficient technology monitors your yarns not only while spinning. While piecing it even scrutinises “sta-tionary yarns” very closely and in this way ensures the quality of your piecings – even when every spinning position is piecing at the same time with Joint Spinning In. On top of this, Corolab Q checks whether the sliver count corresponds precisely to your settings.

Fancy yarns: integrated and productiveQuality without compromise – in the production of fancy yarns too. You digitally save up to 100 fancy compositions and 100 lots in your BD 448’s in-tegrated Fancynation system. The electronically controlled Single Drive Sliver Intake (SDSI) imple-ments the effect programmed per individual spin-ning position with perfectly precise yarn guidance. Even after a yarn break, spinning is continued with the right repeat. The reverse function of the stepper motor makes for particularly striking ef-fects. And all of it more productively than with any other fancy yarn technology of this class: at every spinning position with maximum productivity of up to 150 m/min.
