Abstract:
An apparatus for feeding fiber tufts to a fiber processing textile machine includes a feed chute having upper and lower ends; a densifying air stream generating arrangement for introducing an air stream into the feed chute to densify the fiber tufts therein; a screen forming part of a lower region of the feed chute for separating the air stream from the fiber tufts; an air removal hood immediately adjoining the screen externally of the feed chute; and an arrangement for forcing the air stream through the screen openings out of the feed chute into and through the air removal hood.
Abstract:
An apparatus for making a fiber lap comprises the following combination: a plurality of serially arranged, vertically oriented hoppers charged with fiber tufts from above; removing device for removing the fiber tufts from the hoppers from below; a conveyor arranged to successively run past the hoppers and simultaneously receive fiber tufts therefrom whereby a multilayer fiber tuft mass is formed on the conveyor; a reinforcing device for stabilizing the multilayer fiber tuft mass and forming a fiber lap therefrom; and a wet treatment device.
Abstract:
An apparatus for opening and cleaning fiber material includes consecutively arranged first, second and third clothed rolls each having a clothing thereon. The second clothed roll cooperates with the first clothed roll as a doffer and opening roll and the third clothed roll cooperates with the second clothed roll as a doffer and opening roll. The centrifugal forces generated at peripheries of the clothed rolls increase from roll to roll from the first clothed roll. There is further provided a fiber feeder for advancing the fiber material towards the first clothed roll. Covers closely surround the respective first, second and third clothed rolls which have at least approximately identical diameters. Waste discharge openings are provided in the cover of each clothed roll, and a mote knife bounds each waste discharge opening.
Abstract:
A card feed is disclosed in which, in order to prevent machine stoppages from causing the formation of permanent impressions in a fiber web delivered from a feed chute, a displaceable delivery roller is movable on the occasion of a machine stoppage by means of a pressure-operated reciprocating actuator from an operative position, in which the fiber web is being compressed between a pair of delivery rollers, into another position in which the fiber web is no longer compressed to an extent such that a permanent impression would be produced in it during the period of machine stoppage.
Abstract:
In order to effect a controllable change in the production of a fiber-processing machine there is changed the working width of the fiber-processing machine.
