Definitions

  • This invention relates to a double twist twisting spindle, in which the upper part 'of the spindle, consisting of a threadtake-up disc 'and of a hollow spindle, is rigidly connected with the 5 lower part of the spindle, and in which the thread coming from the supply spools is drawn through a guide passage by means of a threading wire. The thread coming from the stationary supply spool and passing out under the thread take-up disc is then conducted over the thread guide to the winding spool.
  • the known spindles of this type are, however, open to the disadvantage that the hollow twisting spindle or the passage for the running ofi thread has its outlet only at a point of the wharve below the thread guide or below the thread take-up disc.
  • a double twist twisting spindle is known in which two diametrically opposite passages leading outwards are provided for the thread.
  • these two passages only serve for avoiding the impetus moments within the spindle.
  • this construction also possesses the above mentioned disadvantages as two diametrically opposite passages do not yet ensure that, when the spindle has been stopped, one passage will be directed towards the front for threading the thread.
  • there is also the danger of the thread cutting into the material as thread- 5 ing the thread through one and the same passage is easier.
  • the object of the present invention is to eliminate the above mentioned disadvantages.
  • Ac cording to the'invention several passages are provided for the thread on the entire periphery of the wharve or'of the take-up dis'c made in one piece with the wharve, said passages converging in upward direction and terminating in the hollow spindle.
  • These passages may be of round or slot shaped cross section. It is advisable for the transition of the thread from the hollow'spindle to the passages to allow the hollow spindle to project, whereas for the transition from the passages to the take-up disc a so slightly projecting steel wire is arranged so that the thread runs freely through every passage, that is without coming into contact with the side walls.
  • This construction possesses the advantage that 40 a cutting of the thread into the material need no longer be feared as the thread not always runs through one and the same passage but changes the passage when' threaded again.
  • Another advantage consists in the greatly Iacilltated attendance as the spindle need not be turned for the threading of the thread, or the threading hole need not be found for threading the 'wire'. When the spindle is stopped always one of the passages is'directed towards the front 5 so that the attendant can immediately carry out the threading of the thread without difficulty. However, this at the same time results in a simpler construction of the braking device, as it is no longer necessary to turn the spindle by part of the wharve.
  • Fig. 1 shows a double twist twisting spindle in longitudinal section
  • Fig. 2 is a cross section on line II-II oi Fig. 1,
  • Fig. 3 shows in longitudinal section a modified form of construction
  • Fig. 4 is a cross section on line IVIV of Fig. 3.
  • the wharve i and the take-up disc 2 are made in one piece and have several slot-shaped passages 3 which converge in upward direction and end below the take-up disc 2.
  • the bore in the hollow spindle 6 forms extensions of these passages 3 and the spindle which is only short is held in the upper 5 is a stationary thread guide body.
  • the thread is threaded through one of the passages 3 with the aid of a threading wire and pulled out at the lower end of the passage.
  • the short spindle t or the lower outlet of the bore in the spindle projects slightly and at the transition point between the passages 3 and the thread take-up disc 2 a projecting steel wire 6 is provided so that-the thread can run freely through every passage.
  • Another spindle I is fixedin the lower part of the wharve.
  • Figs. 3 and 4 show a similar spindle 411 carrying a thread guide 50. only with the difference that here the upwardly converging passages So do not terminate in the under side of the takeaisasso up disc 2a itself but laterally of the wharve la, and are of round cross section.
  • the spindle la serving as mounting is constructed as a stationary bolt on which the wharve is mounted by means of ball bearings 8a.
  • the thread passes through the hollow spindle 4 and through one of the passages do over the take-up disc 20. and thread guide 5a to the winding spindle la.
  • a wire in also projects slightly into the passages 30. at the outlet end thereof.
  • a double twist twisting spindle of the type with rigidly connected upper and lower spindle parts comprising in combination a wharve and a thread take-up disc made in one piece, a short shaft extending from the upper end of said wharve and having a cential bore, said wharve having a plurality of? thread passages converging upwards from the -lower side of said take-up disc and leading into the central bore of said shaft.
