Abstract: A sliver supplying apparatus for simultaneously feeding a plurality of slivers to a draw frame includes an intake table; a plurality of supply rolls supported in a series by the intake table for guiding the slivers from the coiler cans to the draw frame; and an rpm-setting device for individually setting a circumferential speed of the supply rolls. The rpm-setting device includes a roll drive independent from the drive of the draw frame.

Abstract: A carding machine includes a main carding cylinder, a travelling flats assembly having a plurality of flat bars provided with a clothing cooperating with the clothing of the main carding cylinder; an endless flat bar driving element trained about end sprockets and circulating the flat bars in an endless path; a flat cleaning device supported at a location above the flat bar driving element and including a rotatably supported flat brush roller. A shifting device is provided for raising the flat bar driving element and the flat bars situated at the location towards the flat brush roller for establishing a contacting relationship between the flat brush roller and the clothing of the respective flat bars and for lowering the flat bar driving element and the flat bars situated at the location away from the flat brush roller for discontinuing a contacting relationship between the flat brush roller and the clothing of the respective flat bars.

Abstract: A fiber processing machine for forming a fiber lap from fiber tufts includes a generally vertically oriented reserve chute, a generally vertically oriented feed chute having an inlet adjoining the outlet of the reserve chute, and a fiber feeding assembly drawing fiber from the reserve chute and advancing fiber into the feed chute. The fiber feeding assembly includes a generally horizontally oriented feed roll having a rotary axis extending parallel to the horizontal width of the reserve chute, and a feed tray array cooperating with the feed roll and being composed of a series of individual feed trays lined up along the feed roll and rotatable about an axis. Each feed tray defines a nip with the feed roll. Measuring elements are coupled to each feed tray for emitting signals representing an extent of excursion of the respective feed tray as the fiber material passes through the respective nip. A control and regulating device is connected to the measuring elements for receiving the signals therefrom.
