For sheeting, winding & in-line thermoforming systems The Welex quality & performance you know & trust with newly engineered state-of-the-art customized features: • Sheet widths from 36” to 90” • Sheet gauge from .008” to .125” • Throughputs to 10,000 lb/hr • Monolayer or coextrusion • Up to 9 extruders • Multilayer or Polyside® • XSL Navigator® control system • Flexible & customized roll stand features • Quick roll change • Auto gap control • Movable auxiliary cooling rolls • Roll skewing • Hydraulic, pneumatic & boosted pneumatic roll system While packed with standard features, the Welex Evolution® sheet extrusion system is also flexible to be custom engineered to suit your specific application. Available in monolayer or co-extrusion, the system can comprise up to 9 extruders in sizes ranging from 1.5” to 10” diameter. Custom, highly engineered tooling configurations include state-of-the-art screen changers, melt pumps, mixers, co-extrusion feed blocks & dies. These components can be mounted in the configuration best suited to your installation. After the melt stream, the sheet enters the customizable, high quality chrome roll take-off unit, available in various configurations, including, but not limited to: upstack, downstack, J-stack, inclined stack, horizontal stack. Highly efficient & maintenance-friendly heat/cool systems control the temperature of the chrome rolls with nips that are controlled hydraulically, pneumatically, or by boosted pneumatic. Key features of the take-off include automatic functions for critical product quality attributes such as roll skewing, crowning & electronically-controlled gap adjustment. Downstream & finishing options are painstakingly engineered to maximize the throughput & quality of the desired end product. Stations including coating, treating, slitting, cooling, shearing, winding, laminating, embossing & stacking are all part of the Welex core competency & experience. The system features the award-winning XSL Navigator® control system with a 15” touchscreen operator panel.
