ABSTRACT:
An apparatus for measuring sliver thickness in a drawing frame includes a sliver guiding device having converging inner wall faces for bringing a plurality of simultaneously introduced slivers together to form a sliver assembly constituted by side-by-side positioned running slivers arranged in a plane. The apparatus further includes a sensor element laterally contacting the sliver assembly; and a counterelement laterally contacting the sliver assembly. The counterelement is so supported that it may pivot parallel to the plane of the sliver assembly for purposes of adjustment and immobilization. The sensor element is urged into a resilient contact with the sliver assembly whereby the sensor element undergoes excursions upon variation of thickness of the sliver assembly. The sensor element and the counterelement together define a constriction through which the sliver assembly passes. A transducer converts excursions of the sensor element into electric pulses. A withdrawing roller pair supported downstream of the sliver guiding device pulls the sliver assembly through the sliver guiding device.
