  • the guide rail 15a and the lift guide plate 15 may be in the dovetail form.
  • Reference symbol A' represents a divided or wound thread of the present invention
  • reference numeral 40 indicates a winding section for twisting the divided thread A' by a predetermined number of pieces of thread and winding the same.
  • a yarn having a bundle of threads is unreeled from the yarn bobbin 21 which is installed in the yarn feeding section 20, divided through the yarn dividing section 30, and wound on a weaving bobbin (not shown) of a winding section 40.
  • the thread A' is first provided with tension by the tension controller 10 which is installed between the yarn feeding section 20 and the yarn dividing section 30. Passing through the yarn dividing section 30, the thread A' is again provided with tension by a tension controller 10' installed between the yarn dividing section 30 and the winding section 40, before it is wound.
  • the loose rollers 13 and 13' are moved with respect to the driving roller 12 which is rotating at a fixed position on the fundamental frame 11, thereby adjusting the contact pressure for the driving roller 12, which controls the tension of the thread A' passing between the driving roller 12 and the loose rollers 13 and 13'.
  • the entire tension of the thread A' can also be controlled by varying the extent of engagement of rollers 13, 13' with roller 12 of the transferring the thread A' from the tension controllers 10 and 10' each of which is installed on either side of the yarn dividing section 30.
  • FIG. 7 illustrates another preferred embodiment of a yarn tension controlling device of a divided thread warper, wherein the lift driver 17 is an oil pressure cylinder S which is fixedly connected to the lower surface of the lift frame 16 at the top of the rod R.
  • the cylinder S is associated with an oil pressure system which is under the control of a controller and moves the lift frame 16 up and down while the rod R is ascending and descending.
  • the other components are identical to those of the previously described embodiment. Therefore, the same reference numeral denotes the same component and will be omitted in the description.
  • FIGS. 8-10 illustrate a snapped thread sensing device provided with a divided thread guiding device of a divided thread warper in accordance with a preferred embodiment of the present invention.
  • FIG. 8 is an enlarged perspective view illustrating the principal part of the yarn dividing section 30 for dividing a yarn unreeled from the yarn feeding section 20 into a plurality of pieces of thread.
  • a plurality of bases 22 and support rods 23 are installed in the perpendicular and/or horizontal direction in a rectangular frame 31.
  • Each space defined by the bases 22 and the support rods 23 includes a plurality of thread guiding pieces 26 having a thread guiding ring 26' for guiding the dividing thread.
  • the thread guiding pieces 26 are associated with a switch operating piece 24' of a machine operating switch 24 in order to operate the machine operating switch 24.
  • the switch operating piece 24' of the machine operating switch 24 and the thread guiding pieces 26 are installed in the direction where the thread guiding rings 26' are upwardly inclined, so that the switch operating piece 24' is continually pressed by the tension of thread thereby holding in an "on” position the machine operating switch 24 while the divided thread A is travelling therethrough, and if the travelling thread A is snapped off, the switching operating piece 24' reverts to its upward "off” opsition due to an elastic force applied thereto.
  • the machine operating switch 24 is electrically connected to the driving motor M of the yarn feeding section 20 and the first and second tension controller 10 and 10'. While the tension of the divided thread A is imposed upon the thread guiding pieces 26, the machine operating switch 24 connects the power supply to the driving motor M. If the thread A is snapped off and no tension is imposed upon the thread guiding pieces 26, the power supply to the driving motor M is interrupted by the machine operating switch 24.
  • the switch operating piece 24' of the machine operating switch 24 can be associated with the thread guiding pieces 26 in a direction manner. However, it is more preferable for easier fabrication that the switch operating piece 24' and the thread guiding pieces 26 are associated with each other by means of a coupling piece 25 which has fitting and fastening structures made of a conductive metal on both ends.
  • Reference numeral 50 in FIG. 1 indicates a support foot for supporting the rectangular frame
  • reference numerals 27 and 27' indicate an interval controller for regulating the interval from before the thread passes through a dividing port immediately after passing through the first tension controller 10 to before the thread passes through the second tension controller 10'.
  • an interval controller 27 is positioned before the first tension controller 10. As illustrated in FIG. 9, the interval controller is comb-shaped in order to make the divided thread A travelling in a straight line and passing through the second tension controller 10' at a predetermined distance from it.
  • the snapped thread sensing device provided with a divided thread guiding device as constructed above, unreels a yarn having a plurality of pieces of thread in a bundle from the yarn bobbin 21 which is installed in the yarn feeding section 20, divides the yarn into a plurality of pieces of thread A' through the thread guide rings 26' of the thread guide pieces 26, and winds the threads A' on the weaving bobbin (not shown) of the winding section 40 shown in FIG. 1.
  • first tension is imposed upon the thread A' by the first tension controller 10 of FIG. 1 installed between the yarn feeding section 20 and the yarn dividing section 30.
  • the thread A is provided with second tension by the second tension controller 10' before it is divided and wound.
  • the divided thread A passes through the second tension controller 10' at predetermined intervals by means of an interval controller 27 which is installed between the yarn dividing section 30 and the driving roller 12' of the second tension controller 10'.
  • the thread guiding pieces 26 is pressed down by the tension imposed upon the thread A, thereby maintaining the switch operating piece 24' of the machine operating switch 24 associated with the thread guiding pieces 26,i.e., holding the machine operating switch 24 in an "on" position.
  • the power is applied to the driving motors of the yarn feeding section 20 and the tension controllers 10 and 10'.
  • the thread A which is divided and wound under a tension provided by the first and second tension controllers 10 and 10' in FIG. 1 is wound at a high speed of several hundreds of meters per minute.
  • a piece of thread A is snapped off in such a dividing and winding step, no tension is imposed upon the thread guiding pieces 26 that guide the thread A so that the switch operating piece 24' returns its biased "off" position(by some tensioning means such as elastic), turning off the machine operating switch 24.
  • FIG. 8 is an enlarged perspective view illustrating the principal part of a snapped thread sensing device having a divided thread guiding device in accordance with the present invention, wherein the thread A guided by the two thread guiding pieces 26 is snapped off on the left top side.
  • the tension of the thread is controlled before and after the yarn dividing section, enhancing the quality of the divided and wound threads. Furthermore, if even a piece of the divided thread is snapped off, the driving motors of the yarn feeding section, the tension controllers, and the winding section are suspended immediately, whereby it is possible to avoid the potential defect in the subsequent weaving process.
