GPW–III (S) Over wrapping machine does a single layer over wrapping of BOPP on the Cassettes & similar rectangular product with tear tape at speeds up to 120 Cassettes per minute.

The machine is built from high precision components having the desired metallurgical and heat treatment characteristics resulting in low wear and tear, less maintenance and a longer life. GPW-III (S) is a robust, highly reliable, operator friendly machine having a high productivity and efficiency with negligible rejections.

WORKING PRINCIPLE

Cassettes fed into the magazine are taken forward by an endless conveyor chain. The wrapping material is pulled from a reel, notched for the tab and cut precisely to the required length before being positioned in front of the Cassette packet. The self adhesive tear strip is attached automatically to the film. The cassettes plunges through the wrap material and is delivered into an indexed turret, where the end folds and long seam heat sealing are done. The cassettes are then taken onto a straight bed where the remaining folds are made by stationary guides and heat-sealed.
