    Woven Fabric

    Fabrics are composed of two sets of yarns. One set of yarns, the warp, runs along the length of

    the fabric. The other set of yarns, the fill or weft, is perpendicular to the warp. Woven fabrics are

    held together by weaving the warp and the fill yarns over and under each other.

    The woven plastic fabric is produced using HDPE or PP in wide range of specifications

    depending upon the end use application.

    provides standard and customized equipments to produce woven

    fabrics by circular looms used in storing products such as cereals to chemicals, flour to animal

    feeds, cement to vegetables.

    Extruder

    The extruder with the help of Hi-Q computer optimized screw

    ensures optimum melt homogenization and conveys the melt to theT-die. Universal screws are the best choice for special applications

    with extremely low / high denier of tapes whereas Barrier screws arerecommended for tape deniers used for normal sack applications.The T-die features computer designed flow geometry for optimum

    mass flow distribution and minimum gauge variation across the

    width. Other attractive features of the extruder are grooved bush

    feeding, cold start protection, micro-processor based PID controls, melt temperature, backpressure indicator and pneumatic movement of the extruder cart.

    Extrusion Coating Lines

    Extrusion Coating Machine coatex 1500/90 from has been developedfor extrusion coating lines on flat woven fabric upto 1500 mm width and circular woven fabric in

    widths upto 700 mm with consistently high quality and efficiency of production. It is capable ofcoating both sides of the circular fabric in a single operation. This high speed Extrusion Coating

    Machine produces coated fabric with precise film thickness and is the latest development in the

    field of extrusion coating lines technology. It also includes the features of semi-automatic rollchange during unwinding and rewinding while the machine is in operation. Coating of PP on PP

    fabric and LDPE on HDPE fabric is possible without changing the screw.

    Unwinding Unit

    Coatex extrusion coating machine is equipped with an unwind

    system which has two pneumatic shafts. The fabric rolls are loaded

    onto unwind stands, which can be laterally positioned. The alternate

    use of two positions enables efficient continuous operation,minimized waste and uniform product quality. For semi-automatic

    roll splicing, the fabric web in use, and nearing its end, is affixed tothe reserve web by means of a splicer assembly. To ensure constant

    tension during unwinding, a load cell is used which helps in

    controlling the brake power of the disc brake in the unwinder. Edge Position Control suppliedwith the machine, maintains the edge position of the unwinding roll by lateral adjustment of the

    fabric roll with the help of edge sensors.

    ExtruderThe extruder unit is equipped with screw for high output andexcellent melt-quality. This uniform melt-quality is achieved by

    proper mixing of melt, uniform melt-temperature and by controlled

    heating and cooling zones. The Extruder and the coating die areinstalled above the laminator and are automatically withdrawn

    27/30

    sidewise from their working position whenever the line is stopped. The coating die has a profile

    for perfect flow properties of the melt with highly polished flow channels.

    Pre-heating/ Lamination unit

    The pre-heating/ Lamination unit is equipped with a large diameterhard-chrome plated chill roll, with double walled spiral construction

    and works with high water flow rate to achieve a narrow

    temperature tolerance on the chilled roll surface. The internally

    cooled impression roller and back-up roller assembly provideconsistency of the contact pressure. Impression roller and back-up

    roller are automatically retracted on every stoppage of the machine.

    A draw preheating roller is placed upstream of the laminator to

    ensure good adhesion of the coating.

    Fabric Reversing UnitThe circular woven fabric is reversed during running through a turnbar arrangement so as to coat on both sides of the fabric tube in a

    single operation. This helps in saving of space, energy and alsogives flexibility of production.

    Rewinding Unit

    The continuous rewind system uses an AC motor driven contactroller for wrinkle free rewinding of the coated fabric. For rollsplicing, the web is automatically cut with the help of a rodless

    cylinder; the beginning of the new web is pasted to the new core and

    the full roll is lifted by the swivel arms and delivered onto theplatform. The winding shaft, once removed, is again prepared and

    transferred to the roll change position.
