Definitions

  • the present invention relates to a weaving machine with a leno binding device and a device for regulating the thread tension of the leno and ground threads guided by the leno binding device with two lifting healds and a half heald, the heald hitches being arranged on the oppositely moving upper and lower healds of the loom.
  • a device for regulating the thread tension of the leno and ground threads guided by a leno edging device is known from e.g. EP 1036228 B1 known.
  • Such a Lenherkantenvorraum turns, for example, as a lifting hitch-half combination
  • two lifting healds, in conjunction with a half heald are known to be used for producing a so-called leno weave, also called a leno selvedge in the edge region of a fabric.
  • Such lifting seats are attached directly or indirectly to the heald frames of a weaving machine.
  • the leno thread is passed between half heald and huckle, the ground thread is passed through the eye of the half heald.
  • This principle is in principle from the DE 3818680 C1 known.
  • the weft thread is tied off by the resulting leno weave in combination with the ground thread, which is guided through the loop in the half-heald.
  • a so-called thread hold-down Immediately before the leno binding device, viewed from the Garnzu semiconductor substances, ie, before the heddles is usually a so-called thread hold-down, which ensures that both the leno thread and the ground thread is always performed under tension by the lifting healds or half heald.
  • the object underlying the invention is a loom with a leno bonding device and a device for regulating the yarn tension according to the aforementioned type be provided, in which the tension difference of the threads in the position open or closed tray, is lower than in the prior art according to the EP 1036228 B1 ,
  • the invention proposes that the device for regulating the thread tension comprises two lifting healds and one guided and controlled by the heald half heald, wherein the apparatus for regulating the thread tension is substantially the same design as the leno binding device, the uprights and leno threads are passed through the yarn tension regulating device and the leno bonding device, and the yarn tension regulating device is disposed rotated by 180 ° to the leno bonding device at the looms of the loom.
  • the control is done by arranged on the lifting heald magnets, which come into contact with the metallic half heald at each shedding, as already in the DE 3818680 C1 has been described, which is explicitly referred to in this context.
  • This means that the device for regulating the thread tension on the one hand, and the leno binding device on the other hand are constructed in principle identical, however, when attached to the loom, that is, when attached to the oppositely moving heddle shafts of the loom are rotated by 180 ° to each other. That is to say, a half-heald points upward with its lug arranged in the web, whereas the other half-heald points downwards with its eyelet arranged in the web.
  • the eyelet of the heald of the yarn tension regulating device receives the leno thread of the leno bonding device, whereas the ground yarn of the leno bonding device is interposed between the thighs of the half heald and the corresponding healeage of the yarn tension regulating device.
  • the lifting healds of the yarn tension regulating device have magnets for controlling the half heald.
  • the half-heal itself is U-shaped in the view, wherein the two legs of the half heald, which are connected by the web to the eyelet, in contact with the magnets of the lifting heald like this DE 3818680 C1 with respect to the leno bonding device is known.
  • the lifting healds for receiving by the heald frames each have a hook-shaped element at the end, by means of which the lifting healds can be suspended on the heald frames.
  • the hook-shaped elements of the lifting healds attached to the upper healds are attached to the hook-shaped element have a pivotable latch. Through the pivotable latch, the hook-shaped element can be opened, so that the lifting hooks can be pushed onto the corresponding weaving shank, in order then to fix the lifting healds on the heald by pivoting the bar.
  • the leno binding device is attached to the device for regulating the thread tension by 180 ° twisted to the corresponding mutually moving weaving shafts of the weaving machine, so far the corresponding latch on the lifting jacks of the device for regulating the thread tension at the exact opposite end to the bars on the two lifting healds arranged the leno binding device. That is, the bars are arranged on the hook-shaped elements, which are attachable to the upper healds, so that the bars are easily accessible. In contrast, the lower end of the lifting heald, so also the respective lower heald, accessible only with difficulty.
  • the thread tension regulating device is indicated at 1, the leno binding device at 20.
  • the thread tension regulating device comprises two lifting healds 2, 4 attached to the alternately moving healds 30a, 30b, 30c, 30d of the weaving machine.
  • the lifting healds For attachment of the lifting healds 2, 4 to the corresponding heddle shafts 30a-30d, the lifting healds each have a hook-shaped element 2a, 2b; 4a, 4b, wherein the hook-shaped element 2a, 2b for fixing to the heddle shafts 30a, 30b (upper heald frames) has a pivotable latch 7 (see Fig. 2 ).
  • the lifting healds 2, 4 each show a magnet 9, 10 which cooperates with the metal half heald 11 in the sense that the magnets are controlled by the magnets 9, 10 during halfway hauling by the respective lifting heald.
  • the half-heald 11 has in the region of the web 13, which connects the two legs 12, the eyelet 15. It can be seen that the pivotable latch 7 is located at the end of the respective lifting heald 2, 4 of the device for regulating the thread tension on the Also, the magnet 9, 10 in the lifting heald 2, 4 is arranged.
  • the leno bonding device 20 is formed in the same manner as the yarn tension regulating device 1.
  • the healds indicated at 31a, 31b, 31c, 31d hereby receive the hawks indicated at 22 and 24.
  • the lifting healds 22, 24 here too each have a hook-shaped element 22a, 24a; 22b, 24b.
  • magnets 28, 29 are provided in the lifting seats 22, 24 which, with the half-heald 21 entrained by the lifting healds, alternately come into contact with the limb of the half heald 21 during the respective shedding of the heddle shafts.
  • the half-heald 21 also comprises two legs 12, a web 13 connecting the legs and an eyelet 15 arranged in the web.
  • the hook-shaped elements 22a, 24a of the lifting jacks 22, 24 each have a pivotable bar 27
  • the pivotable latch serves for the simple attachment of the lifting healds with their upper end the corresponding heddles 31a, 31b.
  • the corresponding latches 27 are located on the hook-shaped elements 22a, 24a of the lifting lugs 22, 24, on which the end of the half heald 21 is dressed with the lug 15.
  • Downstream of the leno bonding device 20 is the reed designated 40. Behind the reed is the warp beam marked 50.
  • the stay thread 60 when entering the leno binding device 20, becomes the leno thread
  • the leno thread 70 when entering the leno binding device 20, becomes the ground thread, since it is guided in the loop 15 of the half lap 21 of the leno binding device 20.
  • the device for regulating the thread tension 1 leads to a very small difference in tension of the threads 60, 70 in the respective pocket open position.
  • the twisted by 180 ° arrangement of the apparatus for regulating the thread tension 1 to the leno linking device 20 also ensures that the compartment is opened as large as possible. That is, in particular, the device for regulating the thread tension acts as a thread hold-down.
