machine for the production of a termosaldatrice contemporary cultural of rolls of bags with handles fustellati pretagliati

摘要

A machine (1) continuously fed by at least one flattened tubular film (2) made of plastic material and suitable for producing and winding at least one strip of pre-cut bags (4) with die-cut handles comprises a winding station (40) for the at least one strip of bags (4) and, for each tubular film (2), at least: - a heat-sealing and pre-cutting station (6), suitable for producing a strip of heat-sealed, pre-cut bags (4) from the tubular film (2); - means (8-14) suitable for temporarily stopping sliding of a portion of tubular film (2) with respect to the heat-sealing and pre-cutting station (6); - a die-cutting station (7), acting on the portion of tubular film (2) whose sliding is stopped by said stopping means (8-14), suitable for die-cutting the tubular film (2) or the strip of heat-sealed, pre-cut bags (4) produced by the heat-sealing and pre-cutting station (6). Either the die-cutting station (7) or the heat-sealing and pre-cutting station (6) is fixed, whilst the other station is mounted on a slide (15), movable on a support plane (16), to adapt the distance between the die-cutting station (7) and the heat-sealing and pre-cutting station (6) to the length of the bags (4) to be produced.
