Definitions

  • the present invention consists in guides having the form of twists or helicoids of concave section adjacent the passage in the guide, which are placed-between the rollers of the drawing frames of textile combing, preparing and in particular spinning machines.
  • These guides are electrically grounded to the main body of the machine by their supports and are rapidly exchangeable so that guides having characteristics best adapted to the textile materials to be dealt with can be used and easily exchanged when the material is changed.
  • This condensation of the sliver or the like increases the cohesion of the fibres among themselves (the measure of cohesion being determined by the concavity of the section of the guide along the wall of its passage) and ensures satisfactory retention of short and medium fibres by the com pacting of the fibres themselves; this results in 351 regular and rational drawing, efiective retention of the fibres up to a very short distance from the nip of the drawing rollers and certainty that all the fibres remain perfectly parallel and well staggered during drawing, and the draft can be of a very high value.
  • the above mentioned concavity rounds the sliver or the like and facilitates its conduction in a straight line towards the drawing rollers, reducing the friction of the sliver or the like against the guide, which friction is propor- 5 tional to the length of the guide.
  • the end of the guide can be fashioned into the form of a funnel, to constrict the width of the sliveror the like at the moment of its entry between 50 the drawing rollers (in the manner of the conduits known in flax spinning frames).
  • the present invention can take various forms in its construction and applications; it enables slivers, slubbings or rovings to be drawn irrespective of whether they are twisted or not.
  • Figure 1 shows a guide a of the twisted or helicoidal type, produced by twisting a metal strip of curved section so that the concavity is towards the passage for the sliver or the like 1) formed along the axis of the guide.
  • the latter is supported by two metallic supports 0, 41 mounted in a drawing frame (not represented) so as to be electrically grounded and to thus discharge static electricity.
  • Figure 2 shows the curved section of said guide a
  • Figure 3 which is a plan view thereof, shows the end fashioned to form a constricting conduit.
  • Figure 4 shows a modification in which a similar guide passage is formed by milling a spiral groove in a solid metal bar
  • a Figure 5 shows an example of the application of the device to a spinning frame for very short fibres, A being the feed rollers, D the drawing rollers and 0. indicating diagrammatically the metallic helical guide for the sliver or roving.
  • Figure 6 shows a similar application but for fibres of medium length; the intermediate cylinders I serve to facilitate guiding of the sliver or the like while avoiding an excessive length of the guide of the invention.
  • Figure '7 relates to the spinning of long and slippery fibres; there are two metallic sliverguides a a of opposite hand and an intermediate roller pair I assisting in guiding the sliver.
  • Figure 8 shows the application of the device on a preparing machine with a rotary gill comb K.
  • the twist in. the guide 0 comprises two parts of opposite hand, which facilitates the mounting of the sliver in the machine.
  • the guide necessarily ceases at the location of the comb K, but it is partly continued by an additional guide a on the other side of the drawing rollers D in order to discharge the last residues of static electric charges, at the same time consolidating and rounding the drawn sliver with a View for example to its being tightly wound.
  • the guides instead of being grounded to the body of the machine, can be insulated and supplied with a suitable neutralizing current produced by a source specially provided to this end.
  • a guide for a sliver, slubbing, roving or the like comprising a helicoidally formed piece of electrically conducting material having a passage along its axis, a cross section of said material being concave adjacent said passage and means for neutralizing charges of static electricity collected by said piece of material when in use.
  • a textile machine comprising a drawing frame, a helicoidally formed piece of electrically conducting material having a passage along its axis, a cross section of said material being concave adjacent said passage and an electrical connection between said machine and said piece of material to discharge static electrical charges.
  • a guide for a sliver, slubbing, roving or the like in a drawing frame comprising a metal strip of curved section, helically twisted to form an axial passage towards which the concave face of the strip is turned and means for neutralizing charges of static electricity collected by said strip when in use.
  • a guide for a ribbon or sliver in a drawing frame comprising a metal member having a helical groove of such section cut into it as to form an axial passage therethrough, the section of the metal being concavely curved on the face constituting the wall of the passage and means for neutralizing charges of static electricity collected by said metal member when in use.
  • a guide for a sliver, slubbing, roving or the like comprising a helicoidally formed piece of electrically conducting material having a passage along its axis, a cross section of said material being concave adjacent said passage, means for neutralizing charges of static electricity collected by said piece of material when in use, and said passage being constricted at one end thereof.
  • a guide for a sliver, slubbing, roving or the like comprising a helicoidally formed piece of electrically conducting material having a passage along its axis, a cross section of said material being concave adjacent said passage, means for neutralizing charges of static electricity collected by said piece of material when in use, and said helicoidally formed piece of material having portions thereof wound in opposite directions.
  • a pair of helicoidally formed guides wound in opposite directions said guides being located between the feed rollers and the drawing rollers of said frame and an electrical connection. grounding said guides.
