ABSTRACT:
A universal movable upper tool for a waste-stripping station situated within a machine designed for die-cutting sheet or web-like matter to be converted into packages includes a tool with a rectangular lower plate provided with apertures. Push-rods destined to push waste material through corresponding openings of a perforated upper plate forming a lower tool of the station are fitted against a lower side of the upper plate with the help of quick-fitting means situated on the upper plate's upper surface. Sponge rubber pressers are fitted against a lower side of the upper plate by means of strips affording an easily disengageable mechanical engagement such as hook and loop locking strips (such as VELCRO fasteners) or frictionally engaging locking devices (such as LEGO fasteners).
