  • the invention is more especially, but not exclusively concerned with a mechanism of this kind for spinning a yarn of discontinuous fibrous material.
  • the chief object of the present invention is to provide a mechanism of this kind which is better adapted to meet the requirements of practice than those used up to this time for the same purpose.
  • the yarn spinning mechanism comprises a yarn guide extending through the spinning pot and reciprocable along the spinning axis for guiding the yarn into the pot and an expansible yarn package pivotally mounted on a support about a pivot axis, parallel to said spinning axis, and adapted to be introduced into said spinning pot for removing the yarn package thereof.
  • the support is such that the pivot axis is adapted to be aligned with the yarn spinning axis at least at the end of the expansible spool travel into the spinning pot.
  • the spinning pot and the expansible spool are provided with respective clutch surfaces adapted to cooperate together at the end of the spool travel into the spinning pot.
  • Another feature of the present invention consists in constituting an expansible yarn package spool by a spool body and a sheet of resilient plastic material spiral wound about said spool body and adapted to be kept by its own resiliency in a contracted condition against the wall of said spiral body and to expand radially from this wall under the effect of the centrifugal force- Still another feature of the present invention consists in providing the expansible yarn package spool with means for holding said sheet in an expanded position when the spool is slowed down.

  • the yarn 10 is fed vertically downwardly to pot 1 through guide 8 by a feed device 11 and is carried against the inner wall of pot 1 by an air vortex created by the rotary motion of pot 1. In this manner yarn 10 is driven by the centrifugal force and the reciprocating motion of yarn guide 8, to form a hollow yarn package 12 along the inner cylindrical wall of pot 1.
  • the removing device is constituted by an expansible yarn package spool 13 adapted to be introduced into pot 1 for removing the yarn package 12 therefrom.
  • the yarn package spool 13 is pivotally mounted on a support 14, about a pivot axis.

  • Pot 1 and the expansible yarn package spool 13 are provided with respective clutch surfaces 1a and 16a, which are adapted to cooperate at the end of the spool travel into the spinning pot 1.
  • Expansible spool 13 comprises a spool body 16 and a sheet 17 of resilient plastic material spiral Wound about said spool body.
  • the spool body 16 is pivotally mounted through a ball bearing 15 on a tube 19 rigid with support 14 and has the conical clutch surface 16a at its upper end adapted to cooperate with the corresponding clutch surface 1a of pot 1, in order to drive spool body 16 in rotation by pot 1.
  • the sheet 17 is kept by its own resiliency in a contracted condition against the wall of central body 16 and expands radially from this wall under the effect of the centrifugal force, as shown by FIGURE 2.
  • an inflatable sleeve 18 is placed between spool body 16 and sheet 17.
  • the inflatable sleeve 18 is made of a tube coaxial with spool body 16, the two extremities of tube 18 being tightly fixed to respective smooth cylindrical surfaces 16b and of spool body 16.
  • the space limited by spool body 16 and sleeve 18 is fluid tight and can be connected to a fluid pressure source 22 by means operative when said clutch surfaces, respectively 1a and 16a, come into contact with each other.
  • the spool body 16 and its ball bearing 15 are mounted slidably on tube 19, a spring 20' is wound about tube 19 and adapted to push spool body 16 upwardly through ball bearing 15,.but to yield when support 14 is moved upward above the position for which clutch surface la and 16a are into contact.
  • spool body 16 The displacement of spool body 16 with respect to tube 19 has for its eflFect to connect said fluidtight space with the inside of tube 19, Whichcan be connected with fluid pressure source 22.
  • the cylindrical wall 16d. of spool body 16, in which can slide tube 19 is provided with a valve seat 21 constituting an abutment for the upper part 19a of the tube 19 which is adapted to act as a check valve opening in the direction which pushes spool body 16 upwardly under the action of spring 20; for connecting tube 19 with the fluid tight space, tube 19 is provided with orifices 19b under valve 19a and the wall 16d of central body 16 is also provided with orifices 16c.
  • Pneumatic means fed by fluid pressure source 22 cause the displacement of support 14.
  • Said pneumatic means comprise a cylinder 25 mounted vertically on frame 3 and in which is located a piston 24.
  • Piston 24 is made rigid by rod 23 with support 14 and separates cylinder 25 into, on the one hand, an annular chamber 26 continuously connected with fluid pressure ource 22 through a pipe 27 and, on the other hand, a chamber 28 of circular section which can be connected through a distributor 29 and a pipe 30 either with fluid pressure source 22 (as shown by FIG. 1) or with the atmosphere (as shown by FIG. 2).
  • FIGURE 1 shows chamber 28 connected with fluid pressure source 22. Because of the difference between the cross sections of chambers 26 and 28 and of the weight of the movable assembly comprising support 14, rod 23 and piston 24, this assembly is in its lower position.
  • FIGURE 2 shows chamber 28'connected with the atmosphere. Because of the pressure difference between chambers 26 and 28, said assembly is driven to its higher position. In this higher position fluid pressure source 22 is connected with tube 19 through a passage 31 provided along rod 23 through a passage 32 provided in support 14.
  • support 14 carries two spools 13 and 13a symmetrically disposed about the axis of cylinder 25.
  • Rod 23 is provided with a split pin 33 cooperating with either of the two helical grooves 34 provided in cylinder 25 in such manner that support 14 rotates through 180 every time that the movable assembly goes down.
  • FIGURE 3 shows that sheet 17 is Provided with hooks 17a and 17b adapted to come into contact when the diameters of sleeve 18 and sheet 17 reach their maximum values. These hooks permit of limiting the expansion of sleeve 18 when the yarn is nearly reeled off.
  • the working of this yarn mechanism is as follows: The yarn of fibrous material to be spun is fed downward by the feed mechanism 11 through yarn guide 8, into the spinning pot 1.
