Definitions

  • the annular flanged part retains the traveller in position when the frame is stopped or when the thread draws the traveller towards the spool during its initial operation.
  • a slot is provided in the upper part of the ring.
  • the ring is provided with two grooves having inclined walls formed one on each side of the annular rib, and inside which the curved arms of the traveller freely engage so as to be thrust against the walls and also the bottoms of the said grooves when the traveller is rotated.
  • Fig. 1 illustrates one embodiment of the invention, showing a ring in section and a traveller located inside the ring in elevation,
  • Fig. 2 shows a fragmentary view in elevation from the inside of the ring shown in Fig. 1,
  • Fig. 3 illustrates a further embodiment, showing a ring in section and a traveller and winding support in elevation, and
  • Fig, 4 shows a fragmentary view in elevation from the inside of the ring shown in Fig. 3.
  • Figs. 1 and 2 show a steel ring 1 and a traveller 2 made of resilient steel wire.
  • the traveller mounted inside the ring, forms an open loop laterally extended by two arms 2a, 2b, which possess a curvature corresponding to that of the inside wall of ring 1.
  • the ring 1 is formed with an internal annular T-section flange in on which the traveller, inserted by means of its resilience, is frictionally maintained by its arms 2a, 2b.
  • ring 1 is provided with a slot 5 in its upper part.
  • the length of the arms 2a, 2b can easily be related to technical requirements such as the :gauge of the thread, the speed of the spindle and the required tension.
  • Annular grooves 7, 8 are formed on either side of the flange la inside which are situated, besides the sides 20 and 2d, the arms 2a and 2b which are curved to conform with the curvature of the walls of the said grooves.
  • the thread 3 takes its normal path, passing from the loop of the traveller 2 to be wound on to the spool 4, then when the spindle begins to turn, the thread 3 draws the traveller 2 towards the inside of the ring in the direction of the spool 4 so that the arms 2a and 2b come into contact with the walls 7a and 8a respectively of the grooves 7 and 8.
  • the traveller slides on these surfaces as it rotates until its speed is high enough for its arms 2a and 2b to lose contact with the walls 7a and 8a and to be thrown by centrifugal force against the walls 7b and 8b respectively, and also, because of the inclination of the walls 7b and 8b of the grooves, against the bottoms 7c and 8c of the said grooves.
  • the arms 2a and 2b of the traveller are, in operation, thrust not only against the inside walls of the ring but also against the bottom of the grooves 7 and 8 that a large contact surface is obtained and therefore a greatly reduced pressure applied per unit area, thus permitting higher spindle speeds. Further, the stability of the traveller is greatly enhanced, in its rotation, by the length of its arms and their support in the depth of the grooves.
  • Ring and traveller device for spinning and twisting frames, comprising a ring having an annular rib projecting inwardly between two annular inwardly facing surfaces thereof and a traveller mounted entirely within the ring so as to be guided and supported by said rib and provided with curved arms located parallel to said rib and having substantially the-same curvature as said surfaces, said traveller being mounted for free movement along said rib and being capable of limited radial movement between an outer position in which said arms engage. said surfaces and a radially inner position in which said arms are out of contact with said surfaces.
  • Ring and traveller device for spinning and twisting frames as claimed in claim 1, wherein the ring is provided with a slot extending through the thickness of said ring in a direction transverse to the central plane of the rib and completely interrupting the upper of said two annular inwardly facing surfaces thereof.
  • Ring and traveller device for spinning and twisting frames as claimed in claim 1, wherein the annular rib is provided with annular flanges projecting laterally from its radially inner edges.
  • Ring and traveller device for spinning and twisting frames as claimed in claim 3, wherein the ring is provided with a slot extending through the thickness of said ring in a direction transverse to the central plane of the rib and completely interrupting the upper of said two annular inwardly facing surfaces thereof.
  • Ring and traveller device for spinning and twisting frames, comprising a ring having an annular rib projecting inwardly between two annular grooves provided with inclined walls and located on the interior of the ring, and atraveller mounted entirely within the ring so as to be guided and supported by said rib and having curved arms located parallel to said rib,'said arms having substantially the same curvature as the walls of said grooves, said traveller being mounted for free movement along said rib and being capable of limited radial movement between an outer position in which the arms engage the walls and the bottoms of said grooves and a radially inner position in which said arms are out of contact with said walls and bottoms.
  • Ring and traveller device for spinning and twisting frames as claimed in claim 5, wherein the ring is provided with a slot extending through the thickness of said ring in a direction transverse to the central plane of the rib and completely interrupting the upper of said two annular grooves thereof.
