FOLDING ASSEMBLY, PARTICULARLY FOR PACKAGING MACHINES

摘要

A folding assembly (1), particularly for packaging machines, comprising means for folding a film in order to shape it like a duct (2) that is wrapped substantially hermetically around at least one first product (3) and a subsequent second product (4) to be packaged, the first product (3) and the second product (4) being movable sequentially along a processing line and spaced by a gap that forms a chamber (5), with which a suction device (6) for evacuating the air comprised therein is functionally associated. The suction device (6) comprises a channel that is interposed between the duct (2) and at least the second product (4), an end portion of the channel, which is at least partially flexible and protrudes inside the chamber (5), being provided along its surface with at least one suction inlet for the air contained in the chamber (5).
