Definitions

  • Another object of this invention is the provision of an apparatus that embodies a disturbing means which is not positively connected to a driving mechanism.
  • An additional object of this invention is to provide a system which is characterized by supplying a spinning solution to a spinneret in a varying or pulsating manner, and the thus formed threads are withdrawn from the bath by a positively driven godet, and between the spinneret,
  • FIG 4 is a detailed view of the drive for the spinning pump in partial sectz' n;
  • Figure 5 is a view taken on line 5-.-5 of Figure Figures 6 and ,7 show details of the ratchet and pawl arrangement for driving thevpump shaft a spinning pump III which forces the spinning solution through a filter H and thence through spinning tube I2 and spinneret [3.
  • a thread l4 consisting of a multiplicity of filaments is formed and drawn through a coagulating bath by means of a positively driven draw-off device [6.
  • the spinning pump I per se is of conventional design but is so driven that the spinning solution is extruded at a varying rate. This is accomplished by driving from a shaft I! which is connected to a source of power not shown.
  • the shaft I1 is provided with a pinion [8 which is keyed thereto and which meshes with a gear l9 mounted over at ratchet and pawl assembly 20.
  • pinion I8 As the shaft 11 is rotated in a clockwise direction as viewed in Figure this movement is imparted to pinion I8 which rotates the gear I9, and through the ratchet and paWl assembly 20, the movement is imparted to a shaft 21 which is connected to the spinning pump ID.
  • the ratchet and pawl assembly 20 is comprised of three double pawls 22, 23 and 24 which are connected to and carried by the gear IQ for rotation therewith. These pawls are spring urged into engagement with a ratchet sleeve 25 which is keyed to the shaft 2 I.
  • This ratchet sleeve 25 is hollow and elongated and is connected by bolt 26 to the shaft 2
  • a bolt 21 having an unthreaded bearing surface near its head is threaded into the left end of the ratchet sleeve 25 and supports therefrom the gear I9.
  • the gear I9 is connected to a disc 28 which turns freely on the unthreaded portion of the boIt'Z'I.
  • a washer 29 is interposed between the disc 28 and the head of the bolt 21.
  • gear l8 this movement in an angular sense occurs at a greater speed than the movement of the periphery of the gear l8 despite the fact that gear 18 and disc 44 are both keyed to shaft H.
  • the above described spinning pump drive merely exemplifies one suitable way of forcing the spinning solution through the spinneret in a pulsating manner. Obviously, other mechanism might be used to effect the same result.
  • the apparatus as thus far described will vary the amount of spinning solution supplied to the spinneret which of itself will form thick and thin portions in the thread in a periodic manner if the thread is drawn from the spinneret under a uniform tension.
  • a freely rotatable, heart-shaped, thread-guiding element or disk 45 is interposed between the spinneret l3 and the draw-off device IS.
  • This thread guiding element 45 is eccentrically mounted on an axle 46 and is retained in rotative position by means of collars 41 and 48 (see Figure 2). Also by reference to this figure it will be seen that thread guiding element 45 is provided with a concave thread guiding groove 49.
  • the spinning solution In the operation of the system the spinning solution is forced through the spinneret, and due to the fact that the supply of the solution varies as a result of the variable drive of the spinning pump, a thread is formed having denier variations therein.
  • the thread As the thread is coagulated in the spin bath and withdrawn therefrom by means of a positively driven godet, it i passed around the freely rotatable eccentric thread guidin element or disk and the movement of the thread therearound causes the disk to rotate. Due to the eccentricity of the disk, the thread-which is still very pliable and already contains irregularities, is influenced in an unusual manner.
  • the eccentric disk can be manufactured from any suitable material that is acid resistant, and for different types of thread, can be either Weighted or hollow in the center, so as to adapt the weight of the disk to the strength of the thread.
  • This system can be successfully employed in any rayon plant in which a spinning solution is extruded through spinnerets and coagulated in an acid spin bath. It can also be used for the manufacture of threads having aperiodic denier variations and spun accordin to the dry spinning method wherein the spin bath is replaced by a spinning cell and gas or steam is used as the coagulating medium.
  • the essence of the invention is combining a thread-driven, threadvariations in fabrics results in a fabric that simulates shantung to a much better degree than has heretofore been possible.
  • An apparatus for the production of synthetic threads having aperiodic denier variations therein which comprises a spinneret, means for pumpin a spinning solution through the spinneret in a pulsating manner to form a variable denier thread and means driven solely by, and directly from, the thread for drawing the thread from the spinneret at an irregularly varying linear speed whereby to effect haphazard recurrence of thick and thin portions in the thread.
  • An apparatus for the production of synthetic threads having aperiodic denier variations therein which comprises a spinneret, means for pumping a spinning solution through the spinneret in a pulsating manner to form a variable denier thread and an eccentric disk driven solely by, and directly from, the thread for drawing the thread from the spinneret at an irregularly varying linear speed whereby to effect haphazard recurrence of thick and thin portions in the thread.
  • An apparatus for the production of synthetic threads having aperiodic denier variations therein which comprises a spinneret, a spinning pump provided with a rotatable shaft, a constant drive and an auxiliary drive for the pump shaft to increase the peripheral speed of the shaft at intervals in order to pump a spinning solution through the spinneret in a pulsatin manner to form a variable denier thread, positively driven means for drawing the thread from the spinneret and an eccentric heart-shaped disk interposed between the spinneret and drawofi means driven solely by the thread to cause the thread to travel at an irregularly varying linear speed whereby to effect haphazard recurrence of thick and thin portions in the thread.
  • An apparatus for the production of viscose rayon threads having aperiodic denier variations therein which comprises a spinneret located in a coagulating bath, a spinning pump provided with a rotatable shaft, a constant drive and an auxiliary drive for the pump shaft to increase the peripheral speed of the shaft at intervals in order to pump a spinning solution through the spinneret in a pulsating manner in the coagulating bath to form a variable denier thread, positively driven means for drawing the thread from the bath and an eccentric heart-shaped disk interposed between the spinneret and draw-off means driven solely by the thread to cause the thread to travel at an irregularly varying linear speed whereby to effect haphazard recurrence of thick and thin portions in the thread.
  • a method for the production of thread of synthetic origin having aperiodic denier variations therein throughout its entire length which comprises pumping a spinnin solution through a spinneret in a pulsating manner into a coagulating medium, and drawing the thus formed thread through the medium by a positively driven constant-velocity draw-off device, while superimposing tension variations of an irregular and random pattern upon said thread during its passage between said spinneret and said drawoff device to produce further haphazard denier variations in said thread.
