Definitions

  • the invention relates to a row shed weaving machine with a weaving rotor which has the warp threads holding the warp threads in their up or down position and arranged alternately within lamella combs, and with a control means arranged in the running direction of the warp threads in front of the weaving rotor for lateral deflection and assignment of each Warp thread to a specialist holding element that defines the high or low compartment.
  • the row shed weaving machines together with the wave shed weaving machines form the genus of multi-phase weaving machines, in which a plurality of weft threads which are shifted step by step against each other are always entered into shifts which are also shifted and migrating step wise. While in the wave shed looms the sheds are formed several times over the weaving width and move in the weft direction, in the shed weaving machines one shed is formed over the entire weaving width and the successively formed shed weaves simultaneously move several times in the warp direction.
  • control means for lateral deflection of the warp threads are formed by rotatable control rollers, which run on their jacket with self-contained oblique guide grooves back and forth for each warp thread are provided.
  • the warp threads are laterally deflected in accordance with the course of the guide grooves and are thus assigned to the desired compartment-holding element, this assignment being supported by separating elements which are arranged in the warp threads immediately after the control rollers and are immersed in the warp threads.
  • the invention is intended to provide a row shed weaving machine, the control means of which only little use the warp threads and which can also be adapted to changes in weave without modification.
  • control means extending in the weft direction and hubverenfine in this direction and connected to a controlled actuation device identifies rods with guide eyelets for the warp threads.
  • a row shed weaving machine essentially consists of a warp beam 1, a coating roller 2, a control device 3 for the lateral deflection of the warp threads 4 in order to assign them to a high or low position according to a predetermined fabric pattern, a weaving rotor 5, one Breast boom 6, a take-off device 7 for the tissue 8 produced and from a goods tree 9.
  • the weaving rotor 5 which rotates in operation in the direction indicated by an arrow P, is of a cylindrical shape and is provided on its circumference in the direction of rotation alternately with lamella combs 10 and 11 extending in the longitudinal direction of the weaving rotor and thus in the weft direction.
  • the lamellar combs 10 consist of stop lamellas 12 for striking the weft threads inserted
  • the lamellar combs 11 consist of guide lamellae 13 between which the holding elements 4 and 15, which define the up or down position of the warp threads 4, are arranged alternately.
  • the warp threads 4 are held in their up or down position by the shed holding members 14 and 15 over the entire wrap angle ⁇ of approximately 120 °.
  • the weaving compartments thus formed move one behind the other to the fabric stop edge, with the time in the the compartments are open, a weft thread is inserted into each compartment in a staggered manner.
  • a unit 16 for preparing and inserting weft threads is arranged next to one of the end faces of the weaving rotor 5.
  • This unit 16 does not form part of the invention and is therefore not described in detail.
  • Any suitable weft insertion system can be used in connection with the weaving rotor 5, be it one with shooters, with boats, with projectiles, with reciprocating rods or bands or with a fluid.
  • entry systems known in connection with row shed looms, reference is made to DE-AS 1 089 695 and to US Pat. Nos. 2,742,058, 4,122,871, 4,122,872 and 4,129,153.
  • Fig. 2 it can be seen that along the jacket of the weaving rotor 5, on the one hand, the stop lamellae 12 of the lamella combs 10 and, on the other hand, the guide lamellae 13 of the lamellar combs 11 are each aligned and that the alignment line of the individual guide lamellae 13 in the middle of the intermediate space, the so-called tube, of the assigned stop plates 12 and the alignment lines of the stop plates 12 run in the middle of the tube of the associated guide plates 13.
  • the specialist holding members 14 on the one hand and the specialist holding members 15 on the other hand are aligned.
  • the control device 3 consists of a plurality of rods 17, as shown in the illustration, arranged parallel to the firing direction, which are connected to an actuating device 18 and can be moved back and forth by the latter in the direction of the double arrow A.
  • the rods 17 are provided with guide eyes for the warp threads 4, so that the latter are laterally deflected when the rods 17 move in the longitudinal direction thereof.
  • the number of rods 17 depends on the type of binding to be produced, two such rods 17 are sufficient for plain weave, and more rods 17 must be used for more complicated bindings.
  • the actuating device 18 is of the type of a conventional control mechanism for dobby machines, which uses a program to move each of the rods 17 corresponding to a conventional shaft before each immersion of one of the two lamellar combs 10 or 11 in the warp threads 4 into one of its two end positions. In this end position, the relevant warp threads 4 lie within its tube on the left or right of the lamellae 12 or 13 delimiting this tube and, as a result of the displacement of half a tube pitch between the successive lamella combs 10 and 11, will surely enter the correct tube of the next tube Lamellar comb read.
  • FIG. 3 The figure schematically shows two lamella combs 111 and 11 2 with guide lamellae 13 and the lamella comb 10 running between them with stop lamellae 12.
  • the other two rods 17 shown in FIG. 1 have been omitted, so that every second tube has no warp in the fin comb 10 and only one warp thread 4 in the fin comb 11.
  • the rods 17 and 17 2 have to be moved by the actuating device 18 (FIG. 2) in such a way that the warp threads 4 guided by them assume the positions shown in full lines.
  • the led by the rod 17 Warp threads 4 are moved to the left and the warp threads 4 guided by the rod 17 2 are moved to the right until they rest against the stop lamella 12 delimiting their tube on the left or right.
  • the guide slats 13 can each enter between two spread-apart warp threads 4 into the warp thread array, one of two of these spread-apart warp threads 4 always in a tube of the slat comb 112 with a compartment holding element 14 for the high position and the other in one with one Compartmental organ 15 arrives for the deep compartment.
  • the rod 17 1 in the direction of arrow B and the rod 17 2 are moved in the direction of arrow C so that the warp threads 4 assume the position shown in dashed or dash-dotted lines.
  • the weaving rotor 5 is shown in detail.
  • this consists of a tubular roller 20, which is connected to a drive shaft 21 and is provided on its jacket with a plurality of grooves 22 and 23, which run parallel to the longitudinal axis of the rotor and thus to the weft insertion direction, for receiving the lamellar combs 10 and 11, respectively.
  • the grooves 22 and 23 have an L-shaped cross section, two grooves 22 and 23 each form an associated pair, in which the transverse legs of the L-shaped profile point away from one another.
  • the jacket of the roller 20 has a total of 14 such pairs of grooves.
  • This construction of the weaving rotor 5 from the roller 20 with the circumferential grooves 22 and 23 means that the shed retaining members 15 (FIG. 3) for the low-level position can be dispensed with, since the warp threads 4 are supported in the low-level position as shown in FIG. 4, through the jacket of the roller 20 can be done.
  • the individual lamellar combs 10 and 11 have, instead of the compartment holding members 15 (FIG. 3) for the low compartment position, spacer elements 24 (FIGS. 5, 6) which at most slightly protrude beyond the jacket of the roller 20.
  • both the guide slats 13 and the shed holding members 14 are provided with a recess 19 for the high shed position of the warp threads 4.
  • These recesses 19 form a channel for the weft insertion for each lamella comb 11.
  • two guide slats 13 alternate between a shed retaining element 14 for the high shed position of the warp threads 4 and a spacer element 24, and that two stop slats 12 also delimit a spacer element 24.
  • the stop lamellae 12 of the adjacent lamella comb are each aligned with the tube center of the lamella comb formed by the guide lamellae 13.
  • there are two warp threads 4 in each tube of each of the two lamella combs in the tube between two guide fins 13 both warp threads 4 are located together either in the high or the low position, in the tube between two stop lamellae 12 there is in each case one warp thread 4 in high and the other in the low position.
  • This representation corresponds to the use of four rods 17 indicated in FIG. 1. In contrast, only two rods 17 are shown in FIGS. 2 and 3 for the sake of clarity. Accordingly, every second tube between the stop plates 12 is empty.
  • Each lamella comb 11 is constructed from compartment holding members 14 for the high position, from guide lamellae 13 and from spacer elements 24.
  • the lamellar combs 10 are constructed from spacer elements 24 and from stop lamellae 12.
  • the compartment holding members 14 and the spacer elements 24 are substantially thicker than the stop and guide plates 10 and 13.
  • the thickness of the compartment holding members 14 and / or spacer elements 24 arranged between the plates of the one plate comb 11 or 10 is Three times the thickness of the lamellae of the other lamella comb 11 or 10.
  • each lamellar comb 10, 11 are connected, for example by gluing, to comb portions of, for example, 100 mm in length, and these portions are inserted into the corresponding grooves 22 or 23 and fixed therein.
  • the individual lamella combs 10 or 11 can simply be exchanged without the entire weaving rotor 5 having to be dismantled.
  • the individual elements forming the lamellar combs 10, 11 each have a foot part, the cross section of which is adapted to that of the grooves 22 and 23.
  • the spacer elements 24 are dimensioned such that their upper end does not protrude from the jacket of the roller 20 or only slightly.
  • the compartment holding members 14 for the high compartment position, the stop lamellae 12 and the guide lamellae 13 each have an upper part 25, 26 or 17 projecting beyond the lateral surface of the roller 20 after their foot part.
  • the upper part 25 of the shed holding members 14 for the high shed position has the shape of a finger curved counter to the direction of rotation P of the weaving rotor 5, the outer curved surface of which forms the support for the warp threads 4 in its shed position and the inner curved surface of which forms the guide channel 19 for the weft insertion from above and in Direction of rotation P seen from the front limited. From below, the guide channel 19 is delimited by the jacket of the roller 20, towards the rear from the stop elements 12 of the adjacent lamella comb 10.
  • the upper part 27 of the guide slats 13 has the shape of a parallelogram-shaped wing, which is provided on its edge facing the roller 20 with a contour corresponding to the inner curvature surface of the finger-shaped upper part 25 of the compartment holding members 14 for the high compartment position, which also the channel 19 from above and from limited at the front.
  • the upper part 26 of the stop slats 12 has a sickle-like shape.
  • the tip of this sickle faces the direction of rotation P to the rear.
  • the outer edge of this upper part 26 serves to strike the inserted weft threads and therefore protrudes the furthest from all the mentioned upper parts in the radial direction from the jacket of the roller 20.
  • the outer edge of the upper part 27 of the guide slats 13 is somewhat closer to the roller 20 and the outer surface of curvature of the finger-shaped upper part 25 is somewhat less than half the distance between the jacket of the roller 20 and the outer edge of the upper part 26 of the stop slats 12 which strikes the weft threads.
  • the shape and dimensions of the lamellae 12 and 13 and the mutual distance of the grooves 22 and 23 and thus the lamella combs 10 and 11 are selected such that there is only a small distance of approximately 1 between the individual lamella combs mm or less.
  • the weaving rotor 5 could also be constructed in the manner of the rotary reed known from the shaft weaving looms from individual lamellae in the form of circular plates provided with projections.
  • a web rotor of this type would have to be completely removed, disassembled, reassembled and reinstalled practically every time the article was changed.
