DEVICE AND METHOD FOR SHRINKING A SHRINK FILM ONTO A STACK OF GOODS

摘要

The invention relates to a device for shrinking a shrink film (1) onto a stack of goods (2), wherein a shrink frame (3) is provided, which can be moved on the stack of goods and which surrounds the stack of goods while the shrink film is shrunk on. The shrink frame has a plurality of heating apparatuses distributed over the perimeter of the shrink frame for heating the shrink film for the shrinking process. Furthermore, there is a cover plate (6) that covers the stack of goods and that is arranged in particular at a distance from the top side (7) of the stack of goods during the shrinking process. Side walls (11) extending along the stack of goods are provided between the shrink frame and the cover plate, and intermediate spaces for the heated gases flowing upward are formed between the stack of goods and the side walls. The cover plate can be moved toward the top side of the stack of goods and can be moved away from the top side of the stack of goods. The side walls form a frame, in particular a rigid frame, and the cover plate can be moved within said frame.

主权项

1. An apparatus for shrink-fitting a film onto a stack of objects with a shrink frame that can be moved over the stack of objects and that surrounds the stack of objects during the shrink fitting, the apparatus comprising:
a shrink frame with a plurality of heaters distributed around its periphery for heating the film for the shrinking process and causing gases to flow up around side faces of the stack, a cover plate covering the stack of objects and spaced from the top face of the stack of objects during the shrinking process, and side walls extending along the stack of objects below the cover plate, below the cover plate, and forming clearances between the stack of objects and the side walls for heated gases flowing upward, the cover plate being movable toward the top face of the stack of objects and away from the top face of the stack of objects, the side walls forming a rigid frame within which the cover plate can move.
