摘要

APPLIANCE ON A WIRING PREPARATION MACHINE, ESPECIALLY A TOOTHPAD, ROLLER OR SIMILAR LOAD TO DETERMINE CARD PROCESSING VARIABLES. The present invention relates to an apparatus in a spinning preparation machine, especially a toothed blade card, roller card or the like, wherein a rapidly rotating coated roller is located opposite at least one coated component. associated with the component, in contact with it, a piezoelectric sensor that is connected to an electrical rating device in communication with a display device and / or switching device. In order, by means that are simple in construction, to make it possible to verify the contact intensity between fibers and the component fiber guide liner (carding intensity), the piezoelectric sensor is a sound sensor produced by the The high sensitivity and electrical rating device is able to determine, from the sound produced by the structure, the contact intensity between the fibers and the fiber guide coating of the component (the carding intensity).
