In an apparatus at a spinning preparation machine, especially a card, having a clothed roller, at least machine element located opposite the roller clothing and spaced radially therefrom, and having two fixed lateral holding devices on which work elements are mounted, first and second measuring elements, connected to a control device are provided for detecting variables linked to the dimensions of the roller. The first measuring element comprises a temperature probe for the temperature of the roller surface. The second measuring element comprises a rotational speed sensor for the roller speed. To allow an actual carding nip to be determined, permitting a comparison with a preset carding nip, a third measuring element for the temperature of the holding devices is provided and the control device determines the actual spacing for the roller and the side panels. |
