Abstract: A method and apparatus for securing card-clothed tops to the flats of revolving flat-type carding machines is disclosed, which obviates the necessity for specialist machines used for securing clipped tops to the flanges of the flats. A special type of top clip is provided which, besides being preformed to engage with the bottom side of the top as is usual, also has an inward hooked formation along its upper longitudinal edge. In addition, various kinds of tensioning elements are provided, each of which is engagable with the hooked formations on the clips, and is resiliently loaded, so that in the assembled condition, it causes the clips to pull the top tightly into engagement with the flanges of the flat.

Abstract: The invention relates to opening rollers for open-end spinning apparatus, particularly of the type in which there is a roller body on which is wound a helical coil of metallic wire type card-clothing.The card-clothing coil is located between a pair of abutments, each of which has an annular inner end face in the shape of a helix with an acclivity or step between its maximum and minimum axial displacements, this annular face being complementary in shape to the adjacent end of the card-clothing coil, so that when the ends of the coil are engaged with their respective abutments, there are no recesses between the roller body and the ends of the coil in which lint can lodge.The abutments can be formed by separate distance pieces, or by forming integrally with the roller body, or by moulding after the card-clothing coil has been applied to the roller body.It is preferred to use interlocking type card-clothing wire.

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.
