Definitions

  • Its object is a new self-regulating thread feeder whereby the thread is delivered under a practically constant tension irrespective of the rate at which the thread is delivered and of the variations in the tension of the thread as it leaves the pay-off bobbin.
  • My device is characterized thereby that it com prises a rotary member by means of which the thread is moved along simply by friction, the said member being rotated at such a speed that at all points of its periphery its circumferential speed is higher than the rate at which the thread is consumed by the machine.
  • the shape of the rotary member is that of a frustum of a cone about which the thread winds as a helix from the larger to the smaller end of said cone.
  • a stationary friction member is arranged opposite the skirt of the rotary member for the purpose of preventing the turns of thread wound about it from getting entangled with one another.
  • Figure 1 is an elevational view showing how the thread is moved along between the pay-off bobbin and the yarn carrier.
  • Figure 2 is a sectional view taken on line II-II in Fig. 1.
  • the thread that comes from the pay-off" bobbin passes through the guide eye l after which it winds spirally on the smooth surface of a tapered rotary drum 2 driven at a constant and predetermined angular speed.
  • the distance between the stationary guide eye I and the drum 2 is suiiicient to limit the different turns of yarn on the drum to take the equilibrated positions corresponding to the various take-up speeds of the machine.
  • a pinion 4 is provided which meshes with the teeth of a spur ring 3; the drum 2 may be driven by the machine itself or by any other extraneous hprime mover.
  • the peripheral speed of this latter measured at the very point where the thread leaves the drum, should be higher than the rate at which the thread is taken up by the machine.
  • the device thus behaves like a capstan, with the difference that the drum is a surface of revolution the diameter of which varies along its axis, whereby owing to the action of the brush 5, automatic separation of the turns of the thread coiled about the drum is ensured.
  • a stop-motion may be provided either ahead of or below the thread-feeding drum.
  • a further advantage of such an arrangement is that the thread turns wrapped around the drum can find from themselves a suitable equilibrated position.
  • Fig. 2 more clearly shows the position of the brush 5 on the surface of the drum 2.
