ABSTRACT:
The closing of the end edges of the wrapper (5) which is wrapped around the product in a shape made tubular in a known manner, is performed by folders, some of which are dynamic (15, 15' and 17, 17' ), located in different stations, and some static (8, 8' and 18, 18'). The first pair of dynamic folders (15, 15}') is mounted on the same dynamic folder (14) that folds the first lateral edge (505) of the wrapper. A possible option is to replace the last pair of dynamic folders (17, 17') with a pair of static folders (25, 25'). Before the final rolling stage, the wrapped product passes through a shaped channel (19) that keeps the end folds of the wrapper correctly arranged. The last pair of static folders (18, 18') may be incorporated in this channel. The end edges of the wrapper may be folded in three or in four consecutive portions laid over each other.
