DEVICE FOR CUTTING STACK OF FLAT WORKPIECE
Document Type and Number:
Japanese Patent JPS6165799
Kind Code:
A
Abstract:
Apparatus for cutting stacks of flat workpieces, particularly of undershirt-shaped bags from stacked tubular film sections made of thermoplastic material and formed with side gussets and with top and bottom end seam welds. The apparatus includes a group of two punch-and-die sets, which are mounted in a transversely movable machine frame and include punches associated with drive means for moving the punches up and down, and die plates, which are fixed to the machine frame, and also includes a conveyor for intermittently feeding the stacks to and for removing them from the punches and dies. At least two punch-and-die sets and a drive motor associated with them are arranged in a row in a carriage, which is guided for reciprocation in the machine frame in a direction which is transverse to the direction of travel of the stacks. The carriage is adapted to be secured in the machine frame in two operating positions, in each of which at least one of the punch-and-die sets protrudes laterally from the machine frame.
