Abstract: An apparatus for measuring sliver thickness in a drawing frame includes a sliver guiding device which has an inlet for simultaneously receiving a plurality of side-by-side running slivers having an advancing direction; and a sliver combining arrangement defining a plane extending parallel to the advancing direction for bringing the slivers together to form a sliver assembly constituted by a plurality of side-by-side positioned running slivers arranged in the plane and laterally contacting one another. A movable sensor element is situated at the apparatus outlet and laterally contacts the sliver assembly with an adjustable force. The sensor element undergoes excursions upon variation of thickness of the sliver assembly. The sensor element and a counterelement together define a restriction through which the sliver assembly passes. A transducer converts excursions of the sensor element into electric pulses.
