Extrusion Coating Machine coatex 1500/90 from 
has been developed for 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 of coating 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 roll change 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.
Extruder
The extruder unit is equipped with screw for high output and excellent 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 The Extruder and the coating die are installed above the laminator and are automatically withdrawn sidewise from their working position whenever the line is stopped.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 diameter hard-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 provide consistency 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 Unit
The circular woven fabric is reversed during running through a turn bar arrangement so as to coat on both sides of the fabric tube in a single operation. This helps in saving of space, energy and also gives flexibility of production.
Rewinding Unit
The continuous rewind system uses an AC motor driven contact roller for wrinkle free rewinding of the coated fabric. For roll splicing, 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 the platform. The winding shaft, once removed, is again prepared and transferred to the roll change position.
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 to the 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 supplied with the machine, maintains the edge position of the unwinding roll by lateral adjustment of the fabric roll with the help of edge sensors.
