For several years, Oscillating knife cutting machine are used to cut and severe foamed materials etc. The band knives run over a plurality of knife deflecting pulleys and span freely in a cutting zone for a length of up to 2.5 m. Such a cutting machine is known, for example, from the applicant's documents DE 11 84 069 or DE 75 50 595. With such cutting machines, however, it is necessary to return the band knife above the material so that a large frame is required for the circulating band knife. A Oscillating knife cutting machine is known from DE 101 29 909, in which the band knife is twisted by means of a knife rotating head, so as to perform contour cutting.

Cutting machines, in particular cutting machines for cutting plastic and foamed materials, are faced with ever increasing demands with respect to cutting quality, speed and robustness.

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.

Oscillating knife cutting machine, in particular cutting machines for cutting plastic and foamed materials, are faced with ever increasing demands with respect to cutting quality, speed and robustness.

In hitherto existing cutting machines with an oscillating knife and a so-called material presser foot mounted on a carrier bar which extends in the longitudinal direction of the knife and is displaceable in this direction at the housing, a clamping device is normally mounted to hold the material presser foot at a certain level once it has been raised.

The Oscillating knife cutting machine was to create a cutting machine with an oscillating knife comprising a grinding device which need not be displaced manually, and being of a simpler design than the known cutting machine with an oscillating knife comprising a grinding device which is displaceable
