Definitions

  • the present invention relates to a circular loom, in which inner and outer part shafts are arranged in a circle in two rows around a main shaft of the machine, which part shafts serve in pairs to guide a part of the two warp thread groups distributed all around and which form the weaving or traveling shed via one revolving main shaft an opposing up and down alternating movement is given.
  • Such a circular loom is known from FR-A-25 28 881.
  • a so-called leno weave in which two adjacent warp threads are no longer parallel to each other, but the so-called leno thread the other warp thread, here basic thread, wraps around or crosses in such a way that the weft threads are incorporated in a push-proof manner, although there has long been a desire to be able to produce such leno fabrics on circular looms, in particular for tubular fabrics made of plastic tapes for the production of sacks.
  • the problem here is to design the partial shafts that go in and out in opposite directions so that the two interacting warp threads can be mutually arranged after each interchangeable push.
  • actuating means act on at least one part shaft of a pair of part shafts after each shedding stroke for the momentary lateral relative counter-displacement of the part shafts; and that the warp threads are guided freely from one part of each pair of parts to form a shed by thread guide means and on the other part to change sides; wherein the partial shafts carry comb-like guide means for the warp threads, the tines of which each have a thread eyelet for the shed forming at the free end Have guidance of a warp thread and limit thread guiding slots between them for the warp threads released to change sides; and wherein the comb-like guide means are arranged opposite on the partial shafts of a pair of partial shafts.
  • frame-separating tongues extend in the gaps of the comb-like guide means.
  • the comb-like guide means can both sit on shaft rods and be arranged on the slotted inner or outer run of a belt band forming a pair of shaft parts.
  • the comb-like guide means can be laterally displaced along a horizontal guide or around a tilting bearing.
  • actuating means for the momentary lateral relative counter-displacement of the comb-like guide means of control cams rotating with the main shaft can be pivoted into the lifting movement of the partial shafts, respectively.
  • pawl means which can be actuated by the lifting movement of the partial shafts.
  • the base 9 supports the carrier 9 for the tissue extraction device, which includes the gear means 10 for the fabric take-off, further comprises fabric take-off rollers 11 and 12 and the fabric bale 13.
  • a fabric spreader 14 is also effective in the trigger area.
  • the feed roller 15 for the warp threads or ribbons not shown in detail on the left and the feed roller 16 for the warp threads 50, 51 on the right and also the overflow rollers 17 for these warp ribbons are visible.
  • These warp threads or warp tapes 50, 51 are divided into two warp thread groups arranged all around and are drawn off in a known manner from groups of warp thread spools, not shown in any more detail.
  • one of these shares is then raised by the partial shafts 6, 7, while the other is guided downward from the height of the weaving plane by the so-called shed changing movements, so that an upper warp thread compartment and a lower warp thread compartment are formed, between which at least one in usually several shooters 30 with a weft spool is passed on a horizontal circular path. Due to the circular movement of the shooters, the weft thread 52 (FIG. 8) unwound from the weft bobbin is delivered to the fabric edge of the tubular fabric produced, so that this weft thread can be woven into the fabric. The tubular fabric can then be pulled off and folded flat.
  • the shooters 30 are driven by a control disk 33, which is seated in a rotationally fixed manner on the main shaft 8 of the machine and which pushes with pushing means on the shooters. Furthermore, the main shaft 8 here carries a further control disk 33 ⁇ , which is in operative connection with a plurality of pivoting levers 36 and 37 arranged radially around the latter with so-called shaft rods 46 and 47, which shaft rods 46 and 47 in a known manner the subject-changing movements to the partial shafts 6 and 7 transferred.
  • the partial shafts can also be formed by slotted belt belts, for which purpose an endless belt 26 is guided for each pair of partial shafts via a deflecting roller 29 which is rotatably supported on the upper and lower frame part (FIG. 7).
  • the inner strand and the outer strand of the belt now each carry thread eyelets through which a warp thread of one or the other warp thread family is pulled. Generating an opposing upward and downward alternating movement of the strands of the belt then allows the above-mentioned shedding movement to take place on the two warp thread groups.
  • Such a leno fabric with the intersecting leno threads 51 and the basic thread 50 of two adjacent warp threads and with some weft threads 52 incorporated in a sliding-resistant manner are shown in FIG. 8.
  • actuating means engage for the momentary lateral relative counter-displacement of the Partial stocks.
  • the warp threads are to be guided freely from one part of the pair of part of the pair of shafts for shed formation by thread guide means 24 (FIG. 3) and on the other part of the shaft for a change of sides, as is explained in more detail below with reference to FIGS.
  • the partial shafts 6, 7 carry comb-like guide means 22 for the warp threads 50, 51, the prongs 23 of which each have a thread eyelet 24 at the free end for the shed guiding of a warp thread and between them limit thread guide slots 25 for the warp threads freely guided for changing sides.
  • the configuration is such that the partial shafts 6 and 7 of a pair of partial shafts carry oppositely arranged comb-like guide means 22, which here rest on the shaft rods 46 and 47.
  • frame-fixed separating tongues 610 also extend between the thread guide slots 25, as is indicated in FIG. 5. These separating tongues prevent the changing warp threads from jumping over.
  • the partial shaft 7 moves upwards and the partial shaft 6 downwards, first leno thread 50 lies to the left of the basic thread 51 (FIG. 4).
  • the comb-like guide means 22 of the inner partial shaft 7 is shifted to the right.
  • the warp threads 50 and 51 receive a pretension, which causes the warp threads 50 and 51 to jump over the side at the next zero crossing, as can be seen in FIG. 5, which illustrates the completed change stroke.
  • the leno thread 50 lies to the right of the base thread 51.
  • the comb-like guide means 22 of the inner partial shaft 7 can then return to its other (left) extreme position under the action of the spring 21, which again leads to a change of sides of the warp threads 50 and 51 and so on away.
  • each inner part of the shaft 7 ⁇ extends a pivoting lever 61 which can be swiveled horizontally about an axis 62 and which has stop means 63 and 64 which are pivoted in alternately with each downward movement of the part shaft, whereupon the comb-like guide means 22 in each case from one side to the other and vice versa be tilted.
  • the pivoting of the swivel lever 61 takes place via control cams 60 on the control disk 33 of the machine.
  • FIGS. 10 and 11 A further embodiment variant of the arrangement according to the invention can be seen in FIGS. 10 and 11, which in two different functional positions illustrate the tilting of comb-like guide means 22 ⁇ supported by the tilting bearing 28 in the partial frame 7 ⁇ .
  • a locking shaft 95 which extends horizontally near the relevant partial shaft 7 ⁇ and is mounted in a stationary manner is provided, which carries the cam-like guide means 22 ⁇ near the edges of cam wheels 94 with here three cams 93.
  • These adjusting cams 93 cooperate with pawls 96 projecting from the comb-like guide means 22 ⁇ such that the comb-like guide means 22 ⁇ is tilted from one side to the other with each stroke-like downward movement, stop means 77 limiting this tilting movement.
  • cams 93 and pawl 96 have inclined surfaces according to FIG. 11. Furthermore, a ratchet wheel 90 sits on the ratchet shaft 95 and cooperates with a detent ball 91 loaded by a pretensioning spring 92. This detent ball 91 can weigh in the tooth base of the ratchet wheel 90 by certain angular degrees, in each case a skipping of one or the other cam 93 over the relevant pawl 96 without twisting to enable setting cam wheel division.
  • the same procedure can be used for circular looms in which the partial shafts 6 ⁇ and 7 ⁇ are formed by belt bands 26 in the manner described above, as shown in FIG. 7 in detail.
  • the comb-like guide means 22 ⁇ on the inner partial shaft or strand 7 Tr can be supported for its displacement via a horizontal guide 27 ⁇ or also via a tilting bearing (not shown) with adjusting means according to the above-described embodiments according to FIG. 6 or FIGS. 9 and 10.
