Abstract

A film (9) unwound from a reel by means (24,25) of a contact maker is fed to belts (3) for further transport to a wrapping center (17) assisted by means (4, 5) for an efficient grip to the opposite edges of the film (10). This gripping effect lasts during feeding of a suitable length of the film and during cutting (11,12,14) producing a seperated sheet (13) for wrapping. Whilst wrapping last the contact maker feeds a further part of the film and the whole cycle is repeated.
