Abstract: An improved servicing attachment, for occasional use on a carding machine, having a support beam traversing a roller of the carding machine and removably mounted on the carding machine, a traversing unit reciprocably mounted on the support beam and a motor on the beam for moving the unit, a motor and driven spindle on the unit, a grinder or fettler on the spindle for treating the card clothing on the roller of the carding machine, support structure including stub axle supports on the beam mating with bearings on the carding machine which are aligned with the axis of the traversing unit driven spindle so that there are a range of angles about the axis of the spindle at which the attachment can be oriented without altering the setting between the grinder or fettler and the roller being treated, and handles on the beam ends for lifting the servicing attachment onto and off of the carding machine being serviced.

Abstract: The invention relates to flats as used in carding machines in which there is a releaseable component at one or each end, this component having a surface for frictional engagement on the carding machine and the component being self-retaining on the flat. Spring clip type components are described and there is also a flat made as an extrusion with end parts machined off to adapt the flat to receive the releaseable components.

Abstract: A method and apparatus wherein a machine for carding cotton, man-made fibres and mixtures thereof is provided with a trash removing device usually in the form of a longitudinally fluted roller that cooperates mechanically with a roller clothed with flat-topped card-clothing. The flat-topped clothing roller may be a taker-in roller located in a feed section and the fluted roller is set close to the flat-topped card-clothed roller whereby it is adapted to remove trash projecting above the teeth on the flat-topped card-clothed roller. The trash removing roller is provided with a cowling spaced radially from the periphery of the roller and providing a longitudinally extending gap part way around the roller. A radial lip extends along the one edge of the cowling substantially closing the gap. A deflector lip projects into the gap so as to deflect material travelling in the space between the trash removing roller and the cowling out through the gap.

Abstract: Interlocking metallic wire type card-clothing has a male section protruding from one flank of its rib and a female section formed in the other flank of the rib. The pitch width of the rib is not more than 1.65 millimeters (giving not less than 16 turns per 25 millimeters length of the roller) and the maximum depth of the female section is not substantially greater than half the pitch width of the rib.

Abstract: An arcuate card-clothed element is manufactured by combining a deformable sustaining element which may for example be a slotted stiffener or a layer of fibre glass with a flexible toothed foundation while the sustaining element is in a deformable condition and shaped to the desired arcuate contour of the card-clothed element, and introducing a hardenable bonding medium such as a resin to hold the foundation in the shape of the sustaining element and convert the sustaining element to a substantially rigid state. The card-clothed element may be made in individual sectors, or may comprise sectors cut from a cylindrical assembly built on a former.

Abstract: A method of manufacturing flexible card-clothing for use in textile carding comprising the steps of producing a foamed polyvinylchloride compound having a density of between 0.6 and 1.00 grams per cubic centimeter; applying a sealing coat of a material which is compatible with the foamed compound to a fabric layer; applying a layer of the foamed p.v.c. onto the seaing coat to produce a finished foam layer of between 2 and 5 millimeters thickness on the fabric; heating the applied foamed layer to p.v.c. to cause the foamed layer to fuse; applying a surface layer of sealing material onto the exposed surface of the foamed layer to provide a smooth non-absorbent external surface, with the fabric, foamed p.v.c and surface layer together forming a composite foundation face, combining the foundation face with a foundation back to form a laminated foundation, and then inserting card-clothing wires into the foundation so that parts of the wires project from the surface layer.

Abstract: A method and apparatus whereby a carded web is removed from a rotating member carrying the web by passing the web through a mouth constituted by a nip between a rotating element such as a stripping roller which may have a non-circular cross-section and a stationary element such as a blade-like member that may be oscillated toward and away from the rotating element, the mouth continuously opening and closing in a plane radial of the rotating element.

Abstract: Fiber processing machinery including feed plates, carding plates and web strippers wherein means are provided for carefully adjusting the relative settings of adjacent components of such plates and strippers.

Abstract: A card clothing foundation, to which the carding wires are fitted, has an anti-friction surface layer of polyurethane about 0.006 inch in thickness and containing silicone.
