FIELD: production of protective packing containers from sheets of polyvinylchloride. SUBSTANCE: the offered device includes die and plate of contact heating coaxial to die and provided with slotted hole for air supply. One part of plate of contact heating is made in form of removable plate to whose contact surface, antiadhesion material is applied. Removable plate is encircled over its entire height with hold-down frame made of heat-insulating material which makes it possible simultaneous clamping of thin sheet of thermoplast between removable plate and die and heat insulation of working surface of plate of contact heating, i.e., removable plate. EFFECT: higher efficiency. 5 cl, 1 dwg |
