Operating PrincipleThe sleeve wrapping machines envelope the products under plastic film that may or may not be heat shrinkable. The sleeve wrapping machine is usually the first component in the plastic packaging line.
The products are first sent along the feed conveyor. They are picked up and passed through the sleeve wrapping machine film curtain up to the intermediary conveyor. The necessary film is unrolled automatically from 2 horizontal rolls.
The products are halted by photo-electric cells. The sealing bar assembly closes automatically. A double seal with cut finishes the wrapping of the product. The film curtain is reinstated at the same time for the following product.
