ABSTRACT:
Disclosed herein is a method for wrapping batches of products, in particular candies, and for forming sealed packets, which envisages: a batch of products being supplied to a wrapping wheel; a sheet of heat-sealing material with two lateral downward turned borders being placed above the batch; the said borders being welded one to the other in order to form a tube, the opposite extremities of which are first flattened through the insertion in between them of divarication means; the said extremities then being sealed by welding/pre-folding grippers designed to make, on each welded tubular extremity, weakening lines that aid the subsequent folding of the said extremities.
