Definitions

  • a further disadvantage of this widely known arrangement is the fact that threads which are drawn-off from the bobbins at increased tension as mentioned above but without attaining the breakage tension, do not cause a signal, as the knock-off motion only reports breakage of threads.
  • Such stretched threads impair the quality of the product to a considerable degree. They appear in the finished tissue as glossy threads and lead to rejects.
  • the present invention has for its object the provision of means for avoiding both said disadvantages, namely the Winding of broken thread ends and of undesired stretched threads on the winding frame in order to prevent a further processing of threads which are subject to an increased tension during winding-off from a creel bobbin as a result of pulling or being caught.
  • the present invention contemplates a device comprising cutting means and means for guiding the thread in such a way that the thread approaches these cutting means when a definite tension is exceeded and is cut thereby.
  • the thread is severed by the cutting means placed remote from the winding frame, provoking the stopping of the winding frame in the same way as when the thread breaks, before the increased tension produces glossy threads or a natural breakage of the thread.
  • FIGURE 1 shows a front view of a creel with three bobbins and three cutting means for cutting the thread having an increased tension
  • FIGURE 2 is a plan View of FIGURE 1
  • FIGURE 3 is a sectional view of the device avoiding the further processing of threads having an increased tension
  • FIGURE 4 is a plan view of FIGURE 3.
  • FIGURE 1 of the accompanying drawings a plurality of bobbins 2 are provided on a creel (not shown) the threads 1 of which are passed through the lease reed and the spacing reed (not shown) in the form of a sliver and are wound at uniform tension onto the winding drum of a winding frame (not shown).
  • Every single thread 1 drawn-off from the bobbin 2 is caused to run through an obtuse angle by the blunt edge of a U shaped iron channel 3 (see FIGS. 2 and 4) placed near the bobbin, and through an acute angle in V-shape about a feeler pin 4, whereupon it arrives at the reeds and at the winding drums.
  • Each feeler pin 4 cooperates with a cutting means, such as a blade 5 and guide 6 rigidly mounted on the U-shaped iron channel.
  • Each feeler pin 4 is radially forced into the end portion of a rotatable shaft 7 which traverses the inner space of the U-shaped iron channel 3 and is rotatably mounted with respect thereto.
  • a sleeve 8 is rotatably mounted on the shaft 7 in the interior of the channel 3 where it is protected from dust. This sleeve 8 is urged by a tension spring 9 along a sector-shaped opening 10 against an abutment pin 11 radially protruding from the shaft '7.
  • An angle iron contact portion 12 is associated with each sleeve 8, said angle iron contact portion 12 being fixed to an insulated cover plate 13 closing the open side of the channel 3 and being connected with a contact strip 14 to form a contact.
  • the leg of the portion 12 projecting from the cover plate 13 is provided with a quadrangular hole 25 receiving an insulating block 15 which is axially movable on a rod 16 and is pressed against the portion 12 by a compression spring 17 bearing against a collar 18 fixed to the rod 16.
  • the lower end face 19 of the insulating block 15 serves as stop for the sleeve 8, a leg 20 of which engages this surface 19.
  • the sleeve 8 In the rest position of the represented device the sleeve 8 is rotated by the tension spring 9 until a switch member 24 on the sleeve 8 engages the free end of the angle iron contact portion 12. Upon cutting of the thread by the blade 5, the shaft 7 is angularly moved a small amount by the edge 21 of the sector shaped opening 20 in sleeve 8 acting on the pin 11 and is pivoted together with the feeler pin 4 towards the left in FIGURE 3. In the position of rest of the device the feeler pin 4 is freely pivotable through an angle between a stop 22 fixed to the U-shaped channel 3 and the edge 21.
  • the feeler pin 4- is pivoted into its operating position by the tension of the running thread in which position the leg 20 is pressed with a force corresponding to the thread tension against the lower surface 19 of the insulatin g block 15.
  • the sleeve 8 is so arranged that the pin 11 may continue its angular motion in the milled-off sector-shaped opening of the sleeve in the same direction until the feeler pin 4 meets the stop 22.
  • a tension actuated device for responding to tension in the thread being unwound from a bobbin, said device having a feeler pin around which thread is adapted to be passed, a rotatable shaft on which said feeler pin is mounted, a cutting means cooperating with said feeler pin against which the thread is drawn and cut when the tension gets too great, and a contact adapted to be contacted to close a circuit when the tension in said thread is released suddenly, that improvement comprising an abutment pin on said shaft, a sleeve rotatably mounted around said shaft and having a sector-shaped opening therein in which said abutment pin is free to move, a switch member projecting from said sleeve and adapted to contact the contact when said sleeve is rotated, and spring means connected to said sleeve urging said sleeve to rotate said switch member against the contact in the opposite direction from that in which said shaft will be rotated by increasing thread tens-ion acting on the feeler pin, whereby
  • the improvement as claimed in claim 1 further comprising a leg on said sleeve, and tension adjusting means engaged with said leg and comprising a rod movable axially of itself, a collar fixed on said rod, a block slidable on said rod, said block engaged with said leg on said sleeve, a spring between said collar and said block, and a fixed member against which said block is abuttable, said block being moved away from said fixed member against said spring when said shaft and said sleeve with said leg thereon are rotated by the tension in the thread moving the feeler pin, whereby movement of said rod will adjust the tension in said spring and the total tension on said sleeve against which said shaft is rotated by the tension in the thread acting on the feeler pin.
