The wiper device (10a-g) has at least one automatically activated wiper lip switching unit (20a-g) which is provided in order to switch a wiper lip (18a-g) that is active in at least one sub-process of a wiping process.

Abstract: A cleaning element to be fastened on a cylindrical basic body has a longitudinal axis and is designed as a cylindrical hollow element and comprises a skeleton and a spiked lattice stretched on the skeleton. The skeleton is connected to the spiked lattice by means of a rubber sealing compound, and an inner surface of the cleaning element facing the longitudinal axis is formed by the skeleton or the rubber sealing compound. The skeleton is formed by support rings which are arranged at certain intervals concentric with the longitudinal axis and which are held by means of one or more webs extending in the direction of the longitudinal axis.

Abstract: A grinding device for the flats of a card comprises elastically bendable elements which enter between the clothing points, brush over the side flanks of the points and thereby grind the points. Additional grinding elements are provided in order to treat the front sides of the clothing points. The ground-off material may be removed by a suction device.

Abstract: The invention relates to fastening means (in particular to so called clothing clips) for the fastening of clothing strips on flat rods, made of light metal or light metal alloys. Thereby the fastening means are laid-out in such a manner that, when the flat rods assume their operating temperature, these are not deformed.

Abstract: A drive belt assembly for a revolving flat card includes a flexible belt. At least a pair of connecting elements are integrally formed with the belt. The connecting elements include a cross-beam with an inclined surface. A locking element is disposed between the pair of connecting elements in order to prevent the connecting elements from approaching one another. The locking element is removable from the pair of connecting elements to allow for the approaching of the connecting elements to one another.

Abstract: The present invention relates to a method or device for removing dust, waste and short fibres in the removal zone of a carder or carding machine, having a stripper roller or doffer, a doffing cylinder, an upper and a lower press roller, and a transverse conveyor belt. A solution according to the present invention provides at least one of the following means: means, for example a compressed air device, for generating a preset air flow in the region between the stripper roller, the doffing cylinders and the press rollers; an exhaust device for the area of the lower stripper and the lower press roller; an exhaust device for the area above the upper mote knife.

Abstract: The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.

Abstract: EP-A-627505 describes a connecting system between a revolving flat bar of a revolving flat card and a flexible drive belt. The system is based on snap-in connections. According to EP-A-753610, every snap-in connection comprises two rails (230) which each touch an inclined surface (214, 216) on the belt. According to the present invention such a snap-in connection can be supplemented by a locking element (300) which prevents an inadvertent loosening of the snap-in connection.
