Abstract: In an apparatus at a spinning room machine, especially a carding machine, cleaner or the like, for drawing a clothing onto a roller using a roller drive unit, which apparatus comprises a drive motor arranged to be in drive connection with the roller drive unit or with at least one roller of the machine, the drive motor co-operates with a rotary speed adjustment device. In order to allow, by simple means, automatic matching of the actual value of the speed of rotation to a prespecified value of the speed of rotation, the drive motor co-operates with a closed-loop rotary speed control device which is incorporated into the control and regulation device of the spinning room machine.

Each flat bar has a flat bar clothing carried on an underside of the flat bar for cooperating with the cylinder clothing. The flat bar clothing of the flat bars is oriented at an adjustable angle to the cylinder clothing. Each flat bar has first and second flat bar parts at a longitudinal flat bar end. A first arcuate slide guide is supported adjacent a radial face of the carding cylinder, and the first flat bar part of the flat bars rides on the first slide guide. A second arcuate slide guide is supported adjacent the radial face of the carding cylinder, and the second flat bar part of the flat bars rides on the second slide guide. The second slide guide is wedge-shaped and is shiftable in a circumferential direction of the carding cylinder.

Abstract: A card top bar for a carding machine, has a carrying member and a releasable clothing portion in which card top bar there are provided two card top heads, each of which slides on a slideway, the card top heads comprise at least one sliding region, which is in contact with the slideway, and at least one fixing region, which is in engagement with the rest of the card top bar and which at the same time holds the sliding region.

Abstract: A carding machine includes a main carding cylinder having a cylinder surface carrying a cylinder clothing thereon; a licker-in cooperating with the cylinder for transferring fiber material, including long and short fibers, from the licker-in to the carding cylinder; a doffer cooperating with the carding cylinder for transferring fiber material from the carding cylinder to the doffer; a cylinder cover extending circumferentially underneath the carding cylinder between the licker-in and the doffer; a force-exerting arrangement for applying, to the short fibers, a removing force greater than a retaining force exerted on the short fibers by the cylinder clothing carrying the fiber material; a waste outlet opening provided in the cylinder cover for discharging short fibers from the fiber material carried by the cylinder clothing; a suction hood coupled to the waste outlet opening for receiving the short fibers from the waste outlet opening.

Abstract: A carding machine includes flat bars traveling in an endless path. First and second end rolls periodically reverse the travel direction of each flat bar. First and second drive shafts carry and rotate the respective first and second end rolls. An apparatus for cleaning the flat bars includes a throughgoing, eccentric aperture provided in a radial wall of the first end roll. At any time at least two mutually adjoining flat bars, situated on the first end roll, are aligned at least partially with the aperture. A suction inlet adjoins the radial wall of the first end roll for being periodically brought into alignment with the aperture as the first end roll rotates. A suction chamber is formed by a space bounded by the adjoining flat bars and a surface of the first drive shaft.
