Automatic Rotary Arm Stretch Wrapping Equipment

The CAT (WCAT-450) model is an automatic rotary arm combined with a conveyorized turntable, the ideal stretch wrapping solution for high speed application. This versatile combo gives the possibility of switching operating modes: operation in only rotary arm mode, operation in only turntable mode or operation in combo arm turntable mode at 45 RPM. Expect to improve productivity, operator efficiency while reducing film and labor costs.
