Welding group
The welding group is composed of four rollers that weld the film along the
longitudinal axis and two jaws that weld the film on the transversal axis and cut
the packaging. These four rollers are placed over the running surface of the
product.
WELDING ROLLERS
Before the two welding rollers (A) there are two cold dragging rollers (B) that drag
the product in the welding area. Inside the welding group there are the
resistances (both for the rollers and the jaws) equipped with probes that take the
welding temperature. The rollers for welding are equipped with a machined
welding surface that enables the hermetic welding during the transportation of the
film.
