  • the clamping tool is a cartridge ejecting device.
  • the stamp compresses the pasty mass stored in the cartridge and presses it out of the outlet opening. If the driver described above relieved by reducing a driving force on the propulsion lever, the force of the compressed mass causes a slight return displacement of the punch or the push rod, before their displacement is inhibited by the remindd Wegsperre. This may result in the cartridge relax compressed pasty mass, so that dripping from the outlet opening is prevented.
  • the locking member of the reverse lock may be spaced after the displacement of a support stop.

Against thisthsendanschlag the locking member can strike when it is dragged in the forward displacement of the push rod in the clamping direction by a small distance. This can be done simultaneously with a compression of the return spring.
