Title:
METHOD AND DEVICE FOR APPLYING A FILM PIECE TO A CAN BODY
Document Type and Number:
WIPO Patent Application WO2004065273
Kind Code:
A3
Abstract:
The invention relates to a method for producing a can body (2) which is characterized in that a film piece (3c) is cut from a film web (3b), said film piece (3c) is wound up on a winding spindle (7) from its front edge to its rear edge and is maintained on the winding spindle (7) so that it somewhat overlaps. The film piece (3c) is transferred from the winding spindle (7) to a concave inner surface (11a) and the film areas of the front edge and the rear edge resting against each other are sealed with each other on the concave inner surface (11a) in the area of overlapping (14). According to the invention, a closed film piece (3d) can be transferred without complication onto a can body (2), thereby conferring on the can body (2) the function of the stable structure and on the film piece (3d) the function of the décor or the inner barrier in such a manner that both functions can be optimized in a substantially independent manner.
