Abstract
A card is equipped with a regulating drafting system at the card delivery arrangement. The measuring values for regulating the drafting system are obtained from the drafted fibre sliver. The sliver depositing device can be pre-controlled relative to the drafting system in order to keep the stresses in the fibre sliver between the drafting system and the sliver depositing device within limits. A fibre sliver storage device ( ) is arranged upstream from the regulating drafting system ( ) with relatively small capacity. In order to enable timely action if long term deviations are detected in the fibre sliver mass (m) delivered, a sensor ( ) can be arranged between the card ( ) and the regulating drafting system ( ), and the base rotational speed (U ) of the drive ( ) of the regulating drafting system ( ) can be adapted based on signals transmitted by the sensor ( ).
