Abstract: In an apparatus on a spinning preparation machine, for example a flat card, roller card, draw frame, combing machine or the like, for ascertaining the mass and/or fluctuations in the mass of a fiber material, for example at least one fiber sliver, fiber web or the like, of cotton, synthetic fibers or the like, the fiber material is scanned mechanically by a feeler element the excursions of which are converted into electrical signals. In order to facilitate improved and more accurate measurement of the fiber in a way that is simple in terms of structure and installation, a contactless distance sensor is provided for detecting the position of the feeler element, the sensor being a sensor that measures distance using transmitted waves, and is connected to an electronic evaluating device.

Abstract: In an apparatus for consolidating a conveyable fibre web, for example of cotton, synthetic fibers or the like, there is provided, at the exit from a flat card, roller card or the like, a web funnel together with take-off rollers, the outlet region of the web funnel has a substantially rectangular cross-section, and an endlessly revolving consolidating device, for example comprising two rollers, is provided downstream of the web funnel. In order to improve the apparatus for consolidation, the consolidating device comprises at least two roller pairs arranged one behind the other, which are biased by a force and the speed of rotation of which can be controlled.

Abstract: An apparatus for introducing a plurality of slivers simultaneously to a sliver processing machine includes an arrangement for withdrawing the slivers from coiler cans; a creel; a plurality of supply rolls mounted on the creel and contacting the slivers; a drive, having at least one drive motor, for rotating each supply roll; a common converter connected to the drive; and an rpm setter for setting rpm's of the drive such that the drive has an rpm essentially corresponding to a desired rpm.
