Abstract
A machine for skiving or splitting nonmetallic planar workpieces, in particular plastic-coated paper-like workpieces, is disclosed. The machine has a motor-driven moving knife, in particular a bell knife or hoop knife, whose cutting edge moves around a closed loop and has a specific contour. A grinding device for grinding the knife is provided. In order to increase the service life, a cleaning device is provided, which can be displaced towards the cutting edge for removing contaminants adhering to the cutting edge.
Claims20
A machine for skiving or splitting nonmetallic planar workpieces, said machine comprising:
- a knife having a cutting edge of a specific contour that is movable continuously around a closed loop;
- a grinding device for grinding the cutting edge;
- a cleaning device comprising at least one cleaning element having a cleaning edge corresponding to the contour of the cutting edge, the cleaning edge being engageable with the cutting edge for removing contaminants adhering to the cutting edge, wherein said cleaning device comprises two cleaning elements having cleaning edges respectively for engaging the cutting edge on both sides.
A machine for skiving or splitting nonmetallic planar workpieces, said machine comprising:
- a knife having a cutting edge of a specific contour that is movable continuously around a closed loop;
- a grinding device for grinding the cutting edge;
- a cleaning device comprising at least one cleaning element having a cleaning edge corresponding to the contour of the cutting edge, the cleaning edge being engageable with the cutting edge for removing contaminants adhering to the cutting edge, comprising a drive for moving said at least one cleaning element back and forth along the contour transversely to the closed loop.
