ABSTRACT:
A method of and an apparatus for punching a waste bundle from a stack of bags, especially to form a peripherally-closed hole in the stack as in the production of so-called tie bags, wherein with the lowering of the upper press tool, the waste bundle is cut from the stack of bags lying in a cutting plane pressed into a recess below the cutting plane. The stack is then laterally removed in the plane and an ejector below the plane lifts the waste bundle back into the plane so that it can be swept laterally onto a chute which carries off the waste.
