Definitions

  • the invention relates to a device for producing leno fabrics according to the preamble of claim 1. It also relates to a Loom with such a device.
  • the device is a set blade for guiding standing threads (hereinafter referred to as needle bar) and on the other hand a shaft that is moved up and down, used for moving leno threads.
  • the vertical movement of the leno threads is a first component of movement.
  • the leno threads are moved laterally, d. H. it will performed an offset movement, with this second Movement component that creates the weave typical of leno fabrics.
  • the object of the invention is for weaving machines that are only used to manufacture Turner fabrics are provided to create a device with which the motion sequence necessary for the upright and leno threads can be carried out is, this device due to an appropriate construction Construction of cheaper weaving machines should enable. This task is solved by the device defined in claim 1.
  • the device for producing leno fabrics in a weaving machine comprises a needle bar for upright threads, at least one insert element for Leno threads and means for inserting weft threads.
  • a Swivel assembly is directly on a main drive of the weaving machine connected. This can be done with this swivel arrangement Move the insert element and the needle bar so that the for Upright and leno threads result in the necessary sequence of movements.
  • the dependent claims 2 to 8 relate to advantageous embodiments the device according to the invention.
  • the subject of claim 9 is a Loom with this device.
  • a leno fabric 1 from weft threads 12 and Warp threads namely upright threads 13 and leno threads 14 are - see the Figures 1 to 3 - the upright threads 13 with a needle bar 3 and the Leno threads 14 with an insert element 4.
  • the needle bar 3 carries Needles 31 with eyelets 32.
  • the insert element 4 contains an insert rail 41, which is a perforated rail with holes 42. A series of regular arranged holes 42 is indicated by dash-dotted lines as strips 42 '.
  • Fig. 1 extends the transport direction 10 of the warp threads 13 and 14 (arrows 10a or 10b) and the tissue 1 (arrow 10c) from the back to the front. In the 2, the transport direction 10 is reversed, 3 from right to left.
  • a reed 2 between the needle bar 3 and the tissue 1 becomes Beating a freshly inserted weft thread 12 'actuated: double arrow 20.
  • the needle bar 3 with needles 31 and the insert element 4 with the Insert rail 41 are moved up and down in opposite directions: double arrows 30 or 40a.
  • the first movement component 40a of the insertion rail 41 an offset movement 40b as a second movement component superimposed.
  • the stroke of the offset movement 40b is selected so that the Leno thread 14 between adjacent gaps 34 of the needle bar 3 is moved back and forth. It is at least equal to the distance between two neighboring needles 31.
  • the inventive device with a specially designed Swivel arrangement consisting of components 5, 6 and 7 is in the Figures 2 and 3 shown.
  • the drive power is from the shaft 51 (rotary movement 50) via cam disks 52a, 52b to a cam disk drive 6 transfer.
  • the pivot arrangement comprises a first axis 61 and a second, oppositely movable axis 71, which is parallel to the entry path of the Weft threads 12 (Fig. 1) aligned and spatially fixed in not shown Side walls of the loom are stored.
  • the first axis 61 is through the cam disk drive 6 via the cam disks 52a, 52b and corresponding rollers 62a, 62b set in an oscillating rotation 60.
  • the Needle bar 3 is on a first toggle lever 36, 37 between the first axis 61 and a fixed hinge 38 (Fig. 3).
  • the second axis 71 is a second toggle lever 76a, 76b in a with respect to the first Axis 61 reversed pendulum rotation 70 offset.
  • a connection 74 transfers between the second axis 71 and the insert element 4 this creates the swivel movement and thus creates the vertical one Movement component 40a of the insertion rail 41.
  • the cam disk drive 6 is advantageously in a central region of the first Axis 61 arranged.
  • a bearing of the main drive shaft 51, not shown can be arranged directly next to the cam drive 6. It can a drive can be provided by two or more cam drives 6. Then these cam drives 6 over the inner area of the first Axis 61 arranged distributed.
  • a leno thread deflecting rod 714 is attached to the second axis 71, which serves to temporarily tension the leno threads 14: cf. Fig. 3.
  • the insert element 4 is used to carry out the lateral offset movement 40b movably arranged on the swivel arrangement.
  • the offset movement 40b is by means of at least one motor 8 engaging the insertion element 4 driven.
  • the insert element 4 is over elements 74, which are designed as leaf springs, attached to the second axis 71.
  • the Motor 8 is via a cable 80 to a controller, not shown, and a Energy source connected. It is mounted on a base 78, which on the second axis 71 is firmly attached.
  • a control lever 84 which can be driven by the motor 8 and has the insert element 4 connected.
  • a connection 84a on the insert element 4 consists of a Fork on the control lever 84 and a pin that attaches to the insertion element 4 and protrudes into the space between the fork.
  • Figures 4 to 6 are by a representation of the positions that the Reed 2, take the needle bar 3 and the insert element 4, three Working phases shown.
  • the freshly struck Weft thread 12 'incorporated by the insert element 4 a Offset movement 40b 'in the horizontal direction and a vertical movement 40a 'makes a vertical movement 30' in while the needle bar 3 reverse direction.
  • the reed 2 moves away from the Selvedge: arrow 20 '.
  • the compartment between the upright threads 13 and Leno threads 14 open; a new weft thread 12 can be inserted 5.
  • the weft thread 12 is cast through the reed 2: Arrow 20 ".
  • Fig. 7 shows a second possibility, as well as the offset movement can be executed.
  • the insert element 4 is via rigid elements 74 attached to the second axis 71.
  • the insertion rail 41 can be in one Move the groove in the insert element 4.
  • a motor is 8 '(connection cable 80') spatially arranged.
  • the motor 8 ' is a linear motor with which Interaction with a spring or a second linear motor (not shown; see. following example of Fig. 8) a back and forth movement 40c is executable.
  • To carry out the offset movement 40b is one of Motor 8 'driven rocker 84' connected to the insertion rail 41.
  • the Rocker 84 ' is articulated to a part 79 which is connected to the second Axis 71 is firmly connected. So it is together with the Insert element 4 pivoted up and down.
  • a purely mechanical means 9 for executing the offset movement 40b is shown in Fig. 8.
  • the main drive shaft 51 drives via one Transmission belt 90 to an axial cam 91, which rotates freely the second axis 71 runs. Through the transmission, the speed halved.
  • a profile 92 of the axial cam 91 a roller 93, a Control lever 94, on which the roller 93 is rotatably mounted, and in Interaction with a tension spring 49, the offset movement 40b on Insert element 4 generated.
  • the axis of rotation 95 of the control lever 94 is with Advantageously designed as an eccentric, so that the stroke of the offset movement 40b changed, especially for fine tuning.
  • connection 94a between the control lever 94 and the insert element 4 is the same as connection 84a of the example shown in FIG. 2 educated.
  • the insert element 4 is also by means of Leaf springs 74 attached to the second axis 71 (not shown in Fig. 8).
