Definitions

  • the present invention concerns a turning device for binding fabric edges in a loom.
  • Turning devices are known in which the plying or twisting of the turning threads are effected by turning dics.
  • Each of these turning discs carries two thread bobbins the threads of which are passed through eyes offset with regard to each other by 180.
  • the axes of said are arranged transverse to the warp threads.
  • the eyes move back in the direction of the comb reed.
  • the turning threads each time become loose and are tensioned again.
  • means such as tension springs are provided for equalizing the thread tension.
  • tension equalizers which are adapted properly to regulate the thread tension at high speeds. It occurs that the thread return pull is not effected properly which in turn brings about faults in the goods and can cause disorders.
  • FIG. 1 represents a device according to the present invention with open contacts and push hook or lifter.
  • FIG. 2 shows the device of FIG. 1 with lowered push hook or lifter and closed contacts.
  • FIG. 3 is a top view of the drive for the turning discs.
  • FIG. 4 shows a thread regulator device with closed contacts.
  • FIG. 5 shows the device of FIG. 4 in front view with open contacts.
  • the axes of the two turning discs are substantially parallel to the warp threads.
  • the threads passing from the eyes of said discs to the edge of the goods describe cones, the generatrix of which is formed by the turning thread.
  • the return springs which frequently cause disorders can be omitted.
  • the two turning discs may be driven so as to move in counter direction with regard to each other.
  • This has the advantage that the weft threads are firmly tied up so that it is not necessary, in contrast to heretofore known devices, to turn the turning disc forwards and backwards.
  • a push hook or lifter is provided for holding down the respective lower threads of the rotating shed.
  • This hook or lifter is for instance, by
  • the turning threads are passed through a thread regulator the movable contact members of which are controlled by the threads conveyed into the lower shed. It is by the movement of these threads that the contacts are opened, however, the contacts remain closed when a thread has broken. With a closed circuit, the loom is then stopped in a manner known per se.
  • Such thread controls for the turning threads have heretofore not been suggested.
  • FIG. 1 shows the turning threads 1, 2, 3, 4 on the rotatably journalled bobbins 5, 6, 7 and 8.
  • the bobbins 5 and 6 are rotatable on the turning disc 9, and the bobbins 7 and 8 are rotatably journalled on the turning disc 10.
  • the axes of discs 9 and 10 extend substantially parallel to the warp threads 43 and the discs rotate in the directions of the arrows shown in FIG. 1.
  • the threads 1 and 2 extend from bobbins 5 and 6 through eyes 11 and 12 to the fell at the edge of the goods 13.
  • the threads 3 and 4 which pass through eyes 14 and 15 or disc 10 likewise extend to the edge 13 of the goods.
  • the device 16 comprises a frame 17, two movable contacts 18 and 19 and a fixed contact 20. In view of the turning of discs 9 and 10, always two threads pass outwardly and disengage the contacts as shown in FIGS. 1 and 5.
  • the two inner threads 2 and 3 engage the recesses 21 of a push hook or lifter 22 which is guided by guiding means 23 and 24 and is pulled downwardly by a tension spring 25.
  • An elastic band 26 guided by a roller 27 has one end connected to the hook or lifter 22 while its other end is connected to the sley 44. In view of the reciprocatory movement of sley 44, hook or lifter 22 is moved upwardly and downwardly.
  • FIG. 3 shows the drive for the two discs 9 and 10-.
  • a sprocket wheel 29 with chain 30 and a sprocket wheel 31 are driven and thus also shaft 32.
  • Shaft 32 is journalled in bearing means 33 and has one end provided with bevel gear 34 which meshes with a bevel gear 35 of the type the size of bevel gear 34.
  • Bevel gear 34 is journalled in a bearing 36 and drives the rotating disc 9.
  • FIG. 3 also indicates how the bobbins 5, 6, 7 and 8 with the turning threads are journalled.
  • a helical spring 41 acting as brake takes care of the corresponding thread tension inasmuch as it presses the bobbin against disc 9 or disc 10 and thus brings about a certain frictional connection.
  • the thread or threads are passed through a spring eye 42 which brings about a certain thread equalization. It is only then that they pass through eyes 11, 12, 14 and 15 to the edge 13 of the goods.
  • FIG. 4 shows the two threads 2 and 3 in their intermediate position which means that the contacts 18, 19 and 20 are closed.
  • the threads 1 and 4 are moved outwardly, they act upon the resilient contact members 18 and 19 and disengage the same from the fixed contact member 20.
  • the device according to the present invention furnishes an arrangement which, particularly with smooth warp material such as silk, rayon or other synthetic fibers forms a fixed edge which makes it possible to finish the resulting goods on tenter frames.
  • a device for binding an edge of a fabric being woven in a loom comprising; a pair of rotatable discs each having a pair of bobbins thereon and each disc having thread eyes therein for the threads from the respective said bobbins displaced from each other 180", said threads leading from said bobbins through said eyes to the loom edge of the fabric being woven, said discs being mounted on axes which are substantially parallel to and coplanar with the warp threads of the fabric, and means for rotating said discs and in timed relation to the operation of the loom continuously and in unison so the threads leading therefrom to the fabric will alternately occupy upper and lower positions and will twist at the edge of the fabric.
  • a device which includes a vertically reciprocable member moveable in timed relation to the operation of the loom and operable to hold the lower threads leading from said discs in the lower side of the shed of the loom.
  • a device in which guide means is provided guiding said member in the vertical direction, resilient means connected to said member and biasing it in the downward direction, and actuating means connecting said member with the sley of the loom to cause upward movement of said member when the sley moves toward the fell of the fabric.
  • said actuating means comprises a flexible element connected at one end to said member and at the other end to said sley, and a support roller above said member over which said element is entrained.
  • a device in which a stop motion device in the form of a thread regulator is interposed between said discs and the edge of said fabric, said regulator having a frame through which said threads lead, a pair of normally closed contact means in the frame, and means operated by a respective thread from each disc for opening a pertaining one of said contact means at least during the interval that said respective threads are in the range of their lower position.
