An apparatus for advancing and measuring thickness and/or irregularities of a running sliver includes a tongue-and-groove roll pair composed of a tongue roll and a groove roll which cooperate to define a nip through which the sliver passes for being compressed and advanced. The apparatus has a sensing device located upstream of the rolls which includes a biased, movably supported sensor element that preferably projects into the groove of the grooved roll and cooperates with the groove bottom. The sensing element is deflected in response to thickness variations of the sliver and the deflections are converted into electrical signals. Preferably, the rolls are stationarily supported in use although the distance between them may be manually varied.
