Counter-pressure is recommended
Busch have been manufacturing counter-pressure systems since 1972. The powerful units are easy to handle - available for each die-cutter.
The pneumatic mobile counter-pressure unit for models B, B+P, BL, BLS and CL can be retrofitted and wheels up to the machine in place of the delivery tray. For die-cutter of series A the unit is easy to fit on the support of the delivery tray.
The die is especially manufactured for counter-pressure cutting, with a matrix of plastic or aluminium inside the die. The unit is connected to a compressed air supply. The material is placed in front of the matrix and is held vertical for stabilizing when the hydraulic pressure of the ram pushes the material through the die. When the ram reaches the end of its stroke, the material is pushed back into the feeding tray by the pneumatic counter-pressure cylinder. The die-cut material is then removed from the feeding tray. This reduces the throughput of the machine by half.
For die-cutting small-size inmould labels and neck labels from tempered and varnished aluminium foil. After removing the delivery tray the counter-pressure unit is easy to fit on the support.
The protective hood remains on the machine.
The unit is fitted to the machine instead of the delivery tray. The trolley facilitates the removal and storage of the tray.
