Abstract
A mote knife arrangement is fitted to a flat of a card or carding machine in a position so as to extend substantially transversely to the carding direction and the mote knife or blade is at an inclination so as to extend in a direction substantially opposite to the carding direction. A steel profile defining the mote knife or blade is provided for the mote knife arrangement. The steel profile is positively and non-slidably retained at a support or carrier which is mountable at the associated flat. The steel profile provided for the mote knife arrangement is retained at the support or carrier by permanent plastic deformation of such support or carrier which has a predetermined profile or sectional shape. The longitudinal direction of the profiled support or carrier also extends substantially transversely to the carding direction.
