Definitions

  • the material may come out of the funnel-shaped passage and thereafter travel forward by the side of the collector instead of through it.
  • the supporting face of the known collector is curved to conform to the curvature of the roller upon which it rests, and a nip is thus formed between the lower edge of said face and the fluted adjacent surface of the roller.
  • the tips of stray fibres are liable to be caught in this nip and if such stray fibres are sufficiently interlaced with the others in the strand, the whole strand is pulled down and'forced to pass under the collector. Immediately this happens, the strand pushes the collector out of the way and subsequently proceeds in the unthreaded position.
  • this drawback is overcome b forming the face (or each face) of the collector that may be arranged to be adjacent the associated drafting rollers, with a recess which extends from the inlet side of said face, whereby a clearance is afforded between the (or each) face of the collector and the adjacent surface of the roller with which it is associated.
  • Figure 1 is a, diagrammatic view of known drafting mechanism
  • Figure 2 is an isometric view of a. known collector
  • FIG. 3 is a diagrammatic representation of a drafting mechanism with a collector of the invention applied thereto. the collector being shown in section,
  • Figure 4 is a plan view of the collector of Figure 3 showing the face thereof which is supported upon one of the drafting rollers, and
  • Figure 5 shows the collector of the invention in isometric projection.
  • the known collector is formed with a triangular prismatic body I having a trough 2 formed therein to act as a funnel.
  • the face 3.0f the collector l is shaped so as to lie upon the surface of a fluted draft roller 4 operating against a, roller 5.
  • the fibres 6 pass from between the bands I of a Casablancas drafting mechanism through the collector l and hence between the roller pair 4 and 5. It can occur, as previously indicated, that a loose fibre 8 becomes detached from the main bulk of the fibres and enters between the lower end 8 of the supporting surface 3 of the collector, and the adjacent outer surface of the fluted roller 4. If the fibre 8 separates from the main bulk, the occurrence has no consequence.
  • the fibre or fibres 8 should be sufiicientl-y interlaced with the fibres of the strand 6, the latter is pulled down and .forced to pass under the collector body. As a, result, the strand pushes the collector laterally out of the way and will proceed to pass through the roller pair 4 and 5 without being properly threaded through the collector.
  • the collector body whilst being of the same general shape as that hitherto usual, has the supporting face thereof which seats upon the fluted roller 4, formed with a recess 10 which affords a. clearance between the lower end ll of the supporting surface and the adjacent part of the fluted roller 4.
  • the recess I0 is formed over the length of the supporting surface except for two rib-like portions i2 and I3 which remain at each end of the surface.
  • the recess slopes upwardly towards the end of the supporting surface so as to merge into said surface. It will of course be appreciated that by the provision of the recess, the collector is effectively supported upon the two rib-like portions l2 and I3, and of course. upon the upper part of the surface of the body in contact with the, roller 4.
  • a collector can be formed with a body which is more truly of triangular base prismatic shape, in that the inlet mouth of the trough therein opens only onto one face of the body.
  • both the faces adjacent the pair of associaed draft rollers are substantially similar and in applying the invention both said adjacent faces are preferably provided with a recess.
  • a collector for use-in drafting mechanism for textile fibres comprising a substantially triangular base prismatic-shaped body formed with a funnel-shaped trough having an inlet in one face of said body and an outlet adjacent the line of convergence of the other two faces of said body, and rib-like projections on each end of at least one of said convergent faces, said projections being shaped to lie on the surface of a draft roller and to provide a recess therebetween which extends over substantially the width of the face on which said projections are formed, at the inlet side of said collector body, and merges into said face towards the outlet side of said collector body.
  • a collector for use in drafting mechanism for textile fibres comprising a substantially triangular base prismatic-shaped body formed with a funnel-shaped groove which extends through the said body from one face to a point adjacent the line of convergence of the other two faces, and rib-like projections on each end of that face of said body which bears against a drafting REFERENCES CITED
