Definitions

  • This invention relates to the preparation of fibres for spinning.
  • US-A-3 358 432 proposes a technique for spinning yarn from sliver with a ring spinner in which drafting problems are reduced by supporting fibre being drafted on card-clothing covered rollers.
  • a fibre preparation apparatus including means to receive sliver from a card, means to both open the sliver in to fibres and direct the fibres on to a moving elongate surface, means to exert suction to collect the opened fibres on said elongate surface, control means urged against the surface to hold collected fibres to the surface, means to withdraw collected fibres from between the control means and the surface as a continuous strand and supply the strand to a ring spinning arrangement.
  • the means to withdraw collected fibres may include means to draft the strand to a required count.
  • the means to withdraw collected fibres may include means to apply a false twist to the strand.
  • the surface may be the peripheral curved surface of a hollow disc.
  • the surface may have a groove to receive the fibres.
  • a method of preparing a sliver of fibres for spinning including: opening fibres from the sliver on to a surface, collecting opened fibres on said surface by suction, moving collected fibres on the surface past a control means urged against the surface, withdrawing collected fibres from between the surface and the control means as a continuous strand and supplying the strand to a ring spinning arrangement.
  • a method of preparing fibres for spinning including carding fibres to a state to be suitable for rubbing into slubbings, presenting the carded fibres as slivers, opening fibres from the sliver, directing fibres by said opening action on to a collecting surface, holding fibres on the collecting surface, moving collected fibres held on the surface past a control means urged against the surface, withdrawing collected fibres from between the surface and the control means as a continuous strand and supplying the strand to a spinning arrangement.
  • the method may include the introduction of a core yarn and wrap spinning the fibres onto the core yarn.
  • a generally conventional opening wheel is indicated at OW.
  • a collecting device CD is conveniently of hollow disc form with the peripheral curved collecting surface CS perforated to permit suction to be exerted through the surface by means not shown but indicated by arrow SU. Over part of the periphery suction is obstructed by a suitable plate or like device OB inside the disc.
  • the disc is arranged to rotate in the direction indicated.
  • the opening wheel OW is arranged to direct fibres F opened from a sliver S from a supply SC, in conventional manner, onto the collecting surface CS.
  • the opening wheel rotates past the surface CS in the direction shown by the arrow. Other relative rotations are possible.
  • a control means such as a rubber control roller CR, is urged against the collecting surface e.g. by spring SP, to provide a "nip" and revolves with the rotation of the disc CD. Over the greater part of the surface CS, between opening wheel OW and control roller CR, the collected fibres are held by the suction SU. Suction is obstructed elsewhere, as mentioned above.
  • the individual fibres F opened from the sliver S by the opening wheel OW are moved directly onto the collecting surface CS, partly by the action of the wheel and partly by the suction through the perforated surface.
  • the fibres can be held to the surface by the suction as the disc rotates although in any cases suction only at the initial approach to the surface is enough to ensure that the fibres stay in place on the disc surface.
  • the pressure produced by suction can of course be produced in other ways if preferred, as stated below, the present embodiment being only an example.
  • the opened fibres are not allowed to "float" or form a cloud, being under control throughout the movement between the opening device and the collecting surface. On the surface the fibres have the general appearance of the fibres in a card web. As the disc CD rotates the fibres are carried into the "nip" between the control roller CR and the disc.
  • the fibres which now are a loosely-formed fibre strand FS, are drawn through a pair of parallel friction-twisting belts TB and a pair of drafting rollers DR.
  • the belts apply a false twist and the rollers draft, i.e. draw out, the strand to a required count.
  • the strand is then supplied to a conventional ring-spinning arrangement RS.
  • the false twisting operation can be omitted.
  • the drafting operation can be omitted.
  • the degree of false-twisting and/or drafting, if any, is adjusted as required.
  • the strand prepared as described produces the same surface structure in the spun yarn as does the slubbing which has been treated by the rubbing aprons of the conventional technique.
  • the yarn surface structure preferably emulates that of condenser produced yarn.
  • the opening wheel is about 100 millimetres in diameter.
  • the collecting device disc is conveniently about 160 millimetres in diameter with a curved surface about 30 millimetres wide.
  • the perforated area is about 10 to 20 millimetres wide along the middle of the surface. Lips are provided at each side of the surface and the "nip" control roller fits between the lips to hold the fibres against the surface.
  • the surface may be flat or shaped but the control roller must be shaped to fit.
  • the surface can have a V-groove about 10 millimetres wide, provided with perforations, to receive the fibres.
  • the control roller is arranged to exert a "nip" similar to that in conventional processes.
  • the techniques described are particularly suitable for the longer fibres, about one hundred millimetres or more, of wool for which ring spinning is preferred but the techniques are suitable for shorter fibres.
  • Wool fibres range from twenty to four hundred millimetres in length.
  • a further gain in efficiency is possible as the capacity of a slubbing bobbin is generally much less than that of a sliver can, so when fed from slivers a ring frame can run with much less down-time. Also the transport of sliver In cans is simpler than that of slubbing bobbins.
