ABSTRACT:
A grinding device for the flats of a card comprises elastically bendable elements which enter between the clothing points, brush over the side flanks of the points and thereby grind the points. Additional grinding elements are provided in order to treat the front sides of the clothing points. The ground-off material may be removed by a suction device.
