- 摘要：
- A machine for the production of bags (S) made of alveolar or foamed plastic material starting from at least one continuous web (N) with superimposed flaps (L) fed continuously to a heat-sealing assembly (2). The heat-sealing assembly (2) is actuated according to a pendular motion in synchronism with continuous advance of the web (N), and is pre-arranged for carrying out, at the same time as heat-sealing, halfcuts (T) on the web (N), which is then folded in concertina fashion by means of a lapper assembly (3) at output from the machine.
