FIELD: process engineering.
SUBSTANCE: invention relates to production of plastic bags. Polymer films are fed intermittently in lengthwise direction relative to the machine. Polymer films at intermittent feed are soldered together with the help of thermal soldering device for making of plastic bags from polymer films. Proposed machine comprises cutting blade to cut off film edges at the feed of films and blade actuator to drive the blade at said feed to cut bag angles to preserve cut length connected with edges.
EFFECT: ruled out sticking of film junks to plastic bags.
