Abstract
A chamfer cutting device for cuffing packaging materials comprises a die and a knife part which has a plurality of knives. The die can be moved toward the knife part in order to carry out a cut. The knives are arranged individually in the knife part in a force-dependent manner in such a way that their position with respect to the tool plate varies in a defined way as a function of the force produced by contact with the packaging material or the die. In the event of contact between the knife and the die, a force acts on the knife which does not exceed a predefined maximum force. The chamfer cutting device has the advantage that the die can be guided right up to the knives.
Claims16
A chamfer cutting device for cutting a packaging material, the chamfer cutting device comprising:
- a die;
- a tool plate;
- a knife part including at least two knives, at least one of the die and the knife part being movable relative to the other to cut a packaging material interposed between the die and knife part;
- and
- a gas piston, wherein at least one knife of the knife part is mounted on the tool plate via the gas piston so that position of the at least one knife with respect to the tool plate varies as a function of force produced by contact of the at least one knife with the packaging material or the die.
