Card engine

Abstract

The invention refers to a card engine or card machine comprising a measuring device for detecting the forces prevailing between the revolving cover and the drum. The device shall be improved in such a manner that the quality of the treated fibres can be influenced in an economical and efficient manner. This is achieved by virtue of the fact that the measuring device comprises a sensor for detecting the power consumption of the drive of the revolving cover. The sensor is arranged on the drive of the revolving cover or acts thereas, thereby facilitating the use of commercially available elements, which in turn is more economical.
