ABSTRACT:
A device is described for closing and laterally sealing plastic film wrapped bundles containing sheets or the like, by wrapping them in a thermally shrinkable plastic film, which comprises two sealing plates (25,26) suitable to be moved against lateral opposite sides of a bundle (29) for sealing them. These plates (25,26) are preferably hinged on two slides (2,3 ) suitable to be contemporaneously either approached or moved apart from each other as a function of the width of the bundle (29) to be laterally sealed. Two nozzles (31,32) are moreover provided, which form air jets against laterally protruding portions (30) of the plastic film, so that said protruding portions are easily folded by said plates (25,26). A so closed and sealed bundle is then carried inside an oven for thermally shrinking the wrapped film.
