Definitions

  • This invention particularly relates to the particular method of collecting the filaments in twisted form known as ring spinning.
  • the difdculty in the twisting and winding of artificial filaments by means of the ring spinning process has hereto been that the threads or filaments are extruded, and paid out by the godet roller at such a high speed that some dirficulty is found in getting the thread under the traveller and in applying the thread to the bobbin, without fouling the machinery with an accumulation of loose filaments or threads.
  • the present invention describes two distinct methods of performing the same operation, with the use, in one case, of the waste roller, and in the second case, without any additional device whatsoever.
  • it has the advantage of enahling the ring spinning method of twisting and winding to he used without the use of any extra apparatus and without temporary stoppageoi the spindle, whilst threading the traveller, as it is necessary in the case of other devices, the proper tmist being obtained immediately as soon as the thread is thrown onto the bobbin.
  • 1 provide a loose ring surrounding the bobbin and resting on a bracket, characterized by a traveller partly surrounding the ring section, and placed in a radial plane, adapted to receive the threads, filaments or the like, said ring being provided with two identical notches adapted to engage corresponding smooth cylindrical (that is, headless) steady pins on the bracket, and being thereby prevented from rotating when resting on the said bracket.
  • Fig. 2 shows the loose ring in section, with the traveller threaded
  • Fig. 3 shows the thread heing drawn through the loose ring by hand
  • fig. 5 shows a plan of the device
  • Fig. 6 shows the bobbin in side e1evation, the loose ring being shown in section, and illustrates the alternative method for applying the thread to the bobbin without the waste roller.
  • the untwlsted filaments (2) run round the godet roller (1) over the guide (9), through the traveller (5), and then on to the waste roller (10); (3) is a steadying pin for keeping the loose ring in position; (d) is a loose ring, and (6) is a bracket for carrying the loose ring; (8) represents the means on the spun thread is collected. This may he in the form of hoohin or spool or any other suitable collecting device.
  • the yarn while it is run on the waste roller (10) is pressed on the bottom flange oi the collecting device loy means of a piece of rod (7), which may he of any suitable material.
  • the yarn breaks at (7,) and begins to wind on the bobbin or the like.
  • Fig. 2- shows the loose ring which has been lifted ofi the bracket (6) and the method of passing the thread through the traveler (5).
  • the traveler may he of any design. 'lhe ring may or may not he supplied with two diametrolly opposite raised portions constituting finger pieces (15) (Fig. 5), for conveniently holding the said ring.
  • Fig. 3 shows the loose ring which is still oii its bracket, and the method of passing the thread through the ring by means of the operators finger (11).
  • the ring is then replaced on to its bracket as shown in Figs. at and 5, and the thread is run on to the waste roller ⁇ 10).
  • the collecting device is then placed on the spindle (14) and the yarn then placed on to it as already described. 4
  • the thread (2) is drawn in the form of a loop from the godet roller and threaded on the traveler in the manner described with reference to Figs. 2 and 3.
  • the ring through which the thread is looped as shown in Fig. 3 is then held by the operator in his free hand in any convenient position on the steady pins while the thread (2) takes up the position as shown in Fig. 6.
  • the thread (2) is caused to touch the moving bottom flange of the collecting device; the thread immediately breaks at the point of contact and begins to twist and wind on the collecting device. As soon as this begins the loose ring is replaced on to its bracket (6) and the operation proceeds.
  • the characteristics of this invention are (1) the use of a loose ring, with or without finger. pieces; (2) the superfluity of any help from other threads, loops, rollers or hooks, except when a waste roller is used; (3) there is no need to stop the collecting device in order to start up the twisting and winding.
  • a bobbin for twisting and winding artificial threads, filaments or the like, a bobbin, a bracket mounted in operative relation to said bobbin, smooth cylindrical (that is, headless) steady pins on the said bracket, a loose ring surrounding said bobbin and capable of resting on the said bracket, notches in-said ring adapted to engage said steady pins on the bracket, a traveler, partly surrounding the ring section of said loose ring and placed in a radial plane, being adapted to receive the threads, filaments or the like, and the said loose ring, while being prevented by the steady pins from rotating when resting on the said bracket, being capable of being swiftly lifted vertically free from the rail plate, without preliminary lateral displacement.
  • a bobbin for twisting and winding artificial threads, filaments or the like
  • a bracket mounted in operative relation to said bobbin, smooth cylindrical (that is, headless) steady pins on the said bracket, a loose ring surrounding said bobbin and capable of resting on the said bracket, notches in said ring adapted to engage said steady pins on the bracket, a traveller, partly surrounding the ring section of said loose ring and placed in a radial plane, being adapted to receive the threads, filaments or the like, the said loose ring, while being prevented by the steady pins from rotating when resting on the said bracket, being capable of being swiftly lifted vertically free from the rail plate, without preliminary lateral displacement and provided with two diametrically opposite raised portions constituting finger pieces for conveniently holding
