ABSTRACT:
The teeth of the saw tooth wire of the card clothing are provided with a discontinuity. This discontinuity is located at the tip section of the teeth and at its trailing edge. The discontinuity forms an obstacle member retaining the fibers for a prolonged time on a corresponding drum of a textile machine. This leads to an improved random orientation of the fibres in the fibre fleece leading finally to a more stable non-woven product.
