The Function of Oscillating knife cutting machine

The Oscillating knife cutting machine provides that at least one knife pulley device comprises a drive. In this context it may be provided that one knife pulley of the knife pulley device is driven by this drive. In particular, it is provided that only a single knife pulley of the entire cutting machine is driven. Thereby, it is avoided that an asynchronous drive of a plurality of knife pulleys causes stress on the band knife or causes oscillations during the circulation of the band knife.

In one embodiment of the Oscillating knife cutting machine it is provided that at least one knife pulley device comprises a tensioning device. The tension of the band knife can be adjusted by means of the tensioning device. Thus, the tension of the band knife can be adjusted to the material to be cut, and it is also possible to compensate for knife tensions that vary due to thermal expansion. It is further possible that several knife pulleys of the knife pulley devices respectively comprise one tensioning device, the tensioning device allowing for a displacement of the knife pulleys in the principal plane. Of course, it is possible that several knife pulleys of two different knife pulley devices can share a tensioning device. Preferably, Oscillating knife cutting machine provided those knife pulleys that are not equipped with a drive comprise a tensioning device.
