Abstract: The card for producing a fiber includes a swift and a doffer which takes the carded fibers off the swift and supplies them to a nip formed between at least two rotating rollers. The fiber web emerging from the nip is deposited on the top run of a transverse conveyor which moves axially of the rolls between guide rollers in order to convey the fiber web laterally away from the card. The conveyor has a shoulder on at least one longitudinal side against which the fiber web may abut during travel along the transverse conveyor.

Abstract: A fiber carding web emerging from a pair of crush rollers is taken off and is gathered into a fiber sliver by at least one endless conveyor belt which is guided by means of a first and a second guide roll and is tangent to the pair of rollers across their feeding width. In order to ensure that the carding web is taken off correctly when the relative axial position of the rollers to each other changes, the axis of the guide rolls is supported so that it can be locked in the changed axial position of the rollers and the conveyor belt is guided over a driving roll removed from the plane connecting the axes of the guide rolls.

Abstract: A carding machine has a doffer, a web delivering assembly cooperating with the doffer, a calender unit arranged for receiving a fiber web discharged by the web delivering assembly. The calender unit includes a sliver trumpet and calender rolls. The calender unit is displaceable between an operative position in which the sliver trumpet is situated in the immediate vicinity of the web delivering assembly and an inoperative position in which the sliver trumpet is remote from the web delivering assembly. A start-up tray is movably supported underneath the doffer and the web delivering assembly. The start-up tray guides leading portions of the fiber web from the doffer to the web delivering assembly during start-up operation.

Abstract: A web crushing arrangement for a card web comprises cooperating working rolls (6,7) which are supported by a pressure-loadable support member (23), elastic pressure transmitting means (26,29) being provided between the working roll (7) and the support member (23). By supplying compressed air between the surface of the working roll (7) and the pressing surface (27), of the pressing slat (26) facing and shaped to be complementary to it, an air film is generated between the complementary surfaces.

Abstract: The present invention concerns a crush roll arrangement for a card web with two co-operating working rolls 6 and 10 as used, e.g. for crushing of seed and shell particles contained in a thin card web. At least one of the two rolls 6 and 10 is designed as a hollow member, the cylindrical sleeve 19 of which is pressurized inside and thus deforming in radial direction. By this deformation, which is counteracted by a second roll, the crushing pressure is generated between the working rolls 6 and 10. The sleeve 19 can, among other solutions, be of varying thickness along the longitudinal direction of the roll in such a manner that its radial deformation can be adapted in longitudinal direction along the working rolls 6 and 10.

Abstract: A card is equipped behind the doffer roll (7) with a pair of delivery rolls (8, 8a) for the web (9) provided each with a stationary grazing blade (12, 12a) for seed particles or similar impurities. Between the nip line K of the delivery rolls (8, 8a) and the grazing blades (12) of the delivery roll (8) a web deflecting roll (15) is supported rotatably and drivable in the same rotational direction as the delivery roll (8). The web deflecting device (15) is arranged of, but in the vicinity of, the normal free web exit path (9a) and brings a web (9b) possibly clinging to the delivery roll (8) and carried on thereon back to the normal web exit path (9a) and separates the web (9b) from impurities on the cylindrical surface. The impurities are only subsequently mechanically eliminated by the grazing blade (12), in such manner that the cleaning operation for the delivery roll (8) is effected in two subsequent separate cleaning steps.

Abstract: The dispersibility of cotton filter fly in an elastomeric composition is greatly improved by applying point contact compressive force to the filter fly prior to mixing it into the elastomer.

Abstract: A method of removing a carded web of cotton type fibers from a cotton type carding machine which includes the use of spaced apart control rollers for redirecting and controlling the direction of travel of the web.
