Abstract
The present invention relates to an all-steel card clothing for rollers and/or cylinders of carding machines. Carding machines comprise rollers which are configured to actively take over raw fiber materials from rollers arranged upstream in work direction. Therefore, such card clothings have a relatively large front angle. The problem is that the stability of the card clothings suffers. According to the invention, the teeth have a head angle of >85° in order to solve this problem. The length of the head surface extending at said angle from the tooth tip to the tooth back corresponds to at least ¼ of the length of the tooth pitch. This achieves a considerably more stable card clothing while maintaining the high carding quality.
