  • Patent number: 7730591
    Abstract: An apparatus on a carding machine has a covering comprising work and cover elements lying opposite the clothing of a high-speed cylinder. There is, in succession, an air exhaust opening for the exit of air and an opening for entry of air, past which openings a flow of fibers and air is passed. To allow improved detachment and elimination of short fibers in a simple manner, the spacing of the covering upstream of the exhaust opening is smaller than the spacing of the covering between air exhaust opening and air inlet opening and an airflow flows against the direction of rotation of the cylinder along the surface of the cylinder and flows with short fibers through the air exhaust opening.

  • Publication number: 20080178431
    Abstract: In an apparatus in spinning preparation for separating foreign objects at a roll for opening or doffing fibre material, at least one device for separating the foreign objects is associated with a face of the roll. That device comprises an arrangement for producing a current of blast air flowing onto the face for detaching the foreign objects and carrying them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the roll. To permit separation and allow rapid changes of the action of the blast air current, a bar for mounting the blast nozzles is present and the outlet of the blast nozzles is locally displaceable in relation to the face of the roll.

  • Patent number: 7173207
    Abstract: In an apparatus at a spinning preparation machine, for example a cleaner, opener, carding machine or the like, for detecting waste which is separated out from fibre material, for example cotton, and consists of foreign matter and good fibres and which is collected in a collecting device, there is provided an optical measuring device having a brightness sensor, which measuring device examines the waste. In order to make it possible, by simple means, for the content of good fibres in the waste to be detected and to allow optimum adjustment of the composition of the waste, especially with a high content of trash and low content of good fibres, the waste material is moved past at least one sensor arrangement responding to good fibres, and the sensor arrangement comprises a light source, the light reflected by the moving good fibres being detected by the brightness sensor and being converted into electrical signals, from which the good fibre content can be determined.

  • Patent number: 6145166
    Abstract: In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.

  • Patent number: 5144723
    Abstract: In order to optimally control the air supply in a diverging gap between a card main cylinder and a doffer roll, an air guide plate with a predetermined spacing on the narrowest part between the air guide plate and the surface of the main cylinder and with an aperture angle is arranged close to the main cylinder so that a converging gap is provided between the air guide plate and the surface of the main cylinder. In this converging gap, a pressure head builds up in operation through the air conveyed from the surface of the main cylinder, which leads to an overflow over a nose of the air guide plate. This overflow helps the fleece, which is loosened from the main cylinder, to more easily reach the doffer surface. In order to control the quantity of overflowing air, the gap is to be determined by trial.

  • Patent number: 4126915
    Abstract: An apparatus is illustrated which is especially useful for cleaning the flats of a textile carding machine wherein a rotatable suction conduit has circumferentially spaced slots therein which are successively exposed in cleaning relation to successive flat or carding surfaces by means of a substantially imperforate flexible cover sheet extending about the rotatable suction conduit, being fixed on one end so that the cover extends as a shroud preferably extending in the direction of rotation of the conduit away from the fixed end so as to leave an opening between opposed ends of the shroud. The shroud covers the slots rendering them inactive so that only that slot portion between opposed ends of the shroud actively exert suction. Thus, the suction is concentrated at a specific area, between the ends of the cover, adjacent a limited portion of a flat while permitting rotation of the suction conduit without buildup of excessive lint accumulation as to interfere with the operation of the conduit.
