ABSTRACT:
The machine (1) is provided for production of containers (8) having a trapezoid or triangular form in plane, starting from two films (4) of plastic material superposed on each other. The machine (1) comprises a work station (6) provided with a pair of heat sealing and cutting-out elements (18) extending in directions converging towards each other and transverse to the feed direction of the films (4) so as to simultaneously form two adjacent containers (8) disposed in an inverted relationship with each other in the plane of the films (4). The containers (8) are simultaneousLy removed from opposite sides of the work station (6) by respective removing means (7) provided with clamps (22) and are then released from the clamps (22) and fitted on pairs of underlying needles (36) thus forming stacks.
