Abstract: In an apparatus at a spinning room machine, especially a carding machine, cleaner or the like, for drawing a clothing onto a roller using a roller drive unit, which apparatus comprises a drive motor arranged to be in drive connection with the roller drive unit or with at least one roller of the machine, the drive motor co-operates with a rotary speed adjustment device. In order to allow, by simple means, automatic matching of the actual value of the speed of rotation to a prespecified value of the speed of rotation, the drive motor co-operates with a closed-loop rotary speed control device which is incorporated into the control and regulation device of the spinning room machine.

Abstract: An apparatus at a spinning room machine, especially a spinning preparation machine, for example a carding machine or draw frame, for visual signal display, has at least two light sources in the form of light-emitting diodes (LEDs), each of which is associated with a cover, the signal display—which is in communication with a control device—being capable of emitting signals of light of different colours. In order to provide an apparatus which especially is of simple construction and allows a reduced outlay in terms of manufacture and installation, a plurality of light-emitting diodes or lighting means, which are located inside a clear or opaque cover, are capable of emitting coloured or white light corresponding to the particular operating situation of the spinning room machine.

Abstract: In a method at a spinning preparation machine, for example a cleaner, opener, carding machine or the like, for cleaning fiber material, especially cotton, an examination of the nature of the trash is carried out, which examination is used for adjustment of at least one adjustable cleaning element, for example a separating blade, cleaning grid or the like. In order to make possible improved and undisrupted production by simple means, the optimum adjustment of the at least one cleaning element for a specific fiber batch is stored in a memory of an electronic control and regulation device and, when the same fiber batch is processed again, the optimum adjustment of the cleaning element is implemented automatically.

Abstract: An apparatus for detecting foreign bodies in fiber material includes at least two light sources. At least one of the light sources has at least three light emitting elements. Each light emitting element radiates a light of different color. An arrangement directs the light emitted by the light sources to the fiber material for illuminating the fiber material, and a sensor detects the illuminating light after illumination of the fiber material for emitting an electric signal upon a sudden color change of the fiber material. An arrangement causes the light sources to alternatingly illuminate the fiber material with different colors, and further, an arrangement selects the color emitted by the light sources as a function of the color of the fiber material.
