Definitions

  • the present invention relates to fibre processing apparatus, and in particular, but not exclusively, to apparatus forming part of a cotton card.
  • the cotton fibres are separated from one another by means of a cotton card.
  • the card comprises a rotating cylinder which bears a large number of wire points.
  • Cotton is carried by the main cylinder through a set of stationary pre-carding flats, and through a number of subsequent carding flats. Similar cards may also be used in the processing of a number of synthetic fibres, or of natural/synthetic mixtures.
  • Each blade ( Figure 1) carries a large number of "wires", that is, metal strips blanked out to form a number of teeth. The strips are mounted together on a thin bar and clipped to a support.
  • the carding flat (shown in Figure 2) comprises a body in which are mounted, through respective bores, a number of wire pins. The pins are passed into the respective bores from the rear surface of the body such that the points of the pins are shown from the front face of the body. The pins are then secured in place, by means of adhesive.
  • the body is adapted to be mounted on a support.
  • the body and support take the form of extruded parts which snap-fit together.
  • the support is further adapted to engage with a blade mounting fitting in a card.
  • the support is formed as a single piece, with a central undercut channel shaped to engage a corresponding profile in the mounting fitting.
  • an apparatus for use in fibre processing comprising: a body defining a plurality of points; and a support for the body, the body and support in combination defining a channel for engaging a corresponding mounting profile.
  • said channel is an undercut channel.
  • said body includes a number of ribs, for interlocking with said support.
  • said ribs are adapted to snap-fit together with said support.
  • all or some of said ribs define part of said channel.
  • said support includes a plurality of sections. More preferably, said support includes two longitudinal sections.
  • said points comprise a plurality of pins mounted in corresponding bores in said body.
  • said pins have tails of greater diameter than said bores, such that the pin tails will not enter the bores.
  • said pins are fixed in said bores by means of adhesive.
  • pins For use in a card, use of pins rather than wires offers the advantage that the pins may be arranged at an angle to the cylinder centre line.
  • Conventional wires are typically produced with lines of teeth at an angle of 90°to the centre line, such that each leading tooth shields the following teeth. This problem may be avoided by the use of appropriately located pins; preferably, laterally adjacent rows of points are offset longitudinally. In a preferred embodiment, the offset is such that lateral lines of teeth are at an angle of 86° to the longitudinal axis of the body.
  • an apparatus for use in fibre processing comprising a body defining a longitudinal axis and a lateral axis, a plurality of points and a support for the body, the points being arranged in longitudinally-extending rows, laterally adjacent rows being longitudinally offset.
  • FIG. 1 depicting a prior art carding flat.
  • the flat 40 comprises a number of "wires" 41, that is small sections of metal which have been blanked to form pointed teeth 42.
  • the wires 41 each define a rectangular aperture 43 to permit the wires to be mounted on a bar 44.
  • the wires are then clipped onto a support 45 defining a channel 46 for co-operation with an inverted T-shaped flat-mounting profile on a card.
  • the flat 10 comprises a body 11 with a number of bores 12 through which are mounted many pins 13.
  • the pins may have a tail of greater diameter than the bores, thus preventing the tails from entering the bores.
  • the pins may also be fixed in position by means of an adhesive.
  • the body 11 carries two ribs 14 to interlock with a support 15.
  • the support is of unitary construction and defines a central undercut channel 16 for mounting the flat on the card.
  • the flat 20 comprises a body 21 with a number of bores 22 through which are mounted many pins 23, as described in GB 2323099.
  • the body 21 defines four longitudinally extending ribs 24, 28, 29, 30 profiled to interlock with two separate supports 25, 26. These supports 25, 26 together define a central undercut channel 27 for co-operation with an inverted T-shaped flat-mounting profile on a card.
  • the supports 25, 26 define two substantially "U”-shaped pieces, the lower portions of the legs of each "U” being profiled so as to interlock with corresponding profiling on the ribs of the body.
  • the supports further possess flanges 31, 32 extending inwardly to partially enclose the area between the ribs 24, 29.
  • the profile defined by the flanges 31, 32 in co-operation with the ribs 24, 29 and the body 21 is of a suitable shape for mounting the entire flat assembly on an inverted T-shaped flat-mounting profile on a card.
  • the ribs 24, 28, 29, 30 are further placed so as to provide sufficient access to the rear of the body, when the supports are not present, for insertion and mounting of the pins 23 through the bores 22 during production of the flats.
  • a flat 20 in accordance with the present invention has a plurality of pins 23 arranged in longitudinally extending rows. Laterally adjacent rows 50, 52 are longitudinally offset. This staggering of the pins reduces the obstruction of following pins by leading pins when compared with conventional wire flats, and so increases efficiency and prolongs the life of the flat.
  • the pins have an offset such as to form lateral rows at 86° to the longitudinal axis of the flat.
