Definitions

• the present invention relates to a method for producing a fabric on a weaving machine with a stop and at least one shed, and a heald, in particular for use here.
• the associated long-repeat, individually programmable control option means that, in contrast to the above-mentioned, uniform binding sequences coming from the shaft control, can be flexibly interrupted in such a way that figures, emblems or contours functionally or optically, by contrasts between warp and weft material in the event of interruptions in the binding or lengthening of the float Appearance.
• weaving tapes are created in this way, which are inserted on modern needle-weaving looms, weft by weft as double weft.
• additional elastic threads can also be incorporated, which, for example, with 1H-IT binding make the even-numbered wefts to top shots and the odd-numbered wefts to undershots. This is because the weft threads when Raising of the elastic thread below and the draft of the elastic thread above.
• wefts are inserted which, depending on the need, also produce double-layer fabrics in the form that, for example, the odd-numbered wefts increasingly form the lower fabric layer and the even-numbered wefts increasingly form the upper fabric layer or vice versa. If you interrupt the thread movement, which creates the double layer, by a thread movement, which creates a connection between the upper and lower fabric, you can create contours in the desired way.
• the invention is based on the object of proposing a method for producing a fabric and a heald, in particular for use here, the disadvantages known from the prior art being avoided or at least greatly reduced.
• the object is achieved by a method according to claim 1 and a heald according to claim 4.
• the advantages of the method according to the invention and of the heald that can be used in the process can be described as follows. With this method it is possible to use double-shot technique (two superimposed shots are brought in simultaneously) and with normal halved basic bindings (2H-2T becomes 1H-1T; 4H-4T becomes 2H-2T etc.) shaft-controlled to produce the specialty high and low, by doubling the production by (for example in the case of elastic bands) the (elastic) threads standing in the middle compartment through the interruption of the normal binding threads necessary for the creation of a figure be kept in the middle position by stopping movement despite the full shaft stroke. This movement stop is reached from one end of the elongated hole wire, which is controlled up / down by a corresponding normal jacquard wire movement. The warp thread guided in it cannot be moved beyond the middle position.
• the warp threads which have a figure, emblem and / or contour-producing function, are drawn in both in shaft heddles and additionally in healds according to the invention with a slotted strand eye.
• the slot in question is, for example, in the low position [high position], in which the slot threads, which are moved by normal shaft movement with shaft strands in the up and down position, are not hindered due to the slot position.
• the elongated hole strand is brought into the upward position [draft position] by a normal control impulse and if the elongated strand strand is constricted so that the lower [upper] end of the elongated hole is in the middle position or the middle shed position, the greater warp thread movement - generated by the shaft strands - stopped in the middle position or middle compartment position and prevented from executing a normal binding pattern and thus created the possibility of generating a respective figure point in the normally programmable long repeat. It is of great advantage that the programming is carried out normally on machines that only carry out high / low control. Nevertheless, with this procedure, the double compartment mentioned can be produced, with which tissue can be produced at twice the speed than with methods known from the prior art.
• the output of goods is doubled with the same number of turns of the machine and a correspondingly desired fabric structure.
• the intensity of movement of the jacquard machine is enormously reduced for the benefit of its service life.
• Figures 1 to 4 show different strand positions of the shaft strands as the elongated hole strands.
• Fig. 1 shows schematically and very greatly simplified, and for the sake of illustration with slight lateral distortion, the arrangement of four shaft strands for four warp threads, to which four elongated strand strands are assigned, in the position in which a two-day fabric is produced.
• FIG. 2 shows the positioning of the strands analogous to FIG. 1 at the material formation point of a weaving machine, the strands, however, working in opposition.
• FIG. 3 shows schematically and very greatly simplified and for reasons of illustration with slight lateral distortion, the arrangement of four shaft strands for four warp threads to which four elongated strands are assigned, in the position in which a single-layer fabric is produced.
• FIG. 4 shows the positioning of the strands analogous to FIG. 1 at the material formation point of a weaving machine, the strands, however, working in opposing action.
• Fig. 5 shows a very simplified and schematic of an elongated hole strand according to the invention.
• Figure 1 shows a highly schematic of the shedding and material "area of origin" in a weaving machine 14, in which two pairs of heald strands 1, 2 and 3, 4 are shown between a stop 12 and a "warp thread delivery point" 20 by the warp threads I, II and III , IV walk through it.
• the warp threads I, II are guided through a respective elongated strand eye 16 by pairs of elongated strand strands Ol, O2 and XI, X2 arranged between the shaft strands and the stop.
• the shank strands which are actually arranged one behind the other in the viewing direction penetrating the sheet vertically are shown next to one another in order to be able to understand the course of the warp threads guided through them.
• the shots SO, above the middle compartment line 18 and SU, below the middle compartment line 18 are shown in a stylized manner.
• the double weft consisting of the upper weft SO and the lower weft SU is in a direction which penetrates the plane of the drawing essentially vertically in the upper compartment formed by the warp threads I and II (weft SO) and at the same time in the lower compartment formed by the warp threads III and IV (weft SU ) entered.
• the warp threads I and II together with the upper weft SO form an upper layer OL
• the warp threads III and IV together with the lower weft SU form a lower layer UL of a two-layer fabric, the four warp threads representing the smallest repeat of a multiple thread.
• the first shaft strand 1 lifts the first warp thread I into the highest upper position, while the second shaft strand 2 pulls the warp thread II into its lowest position.
• the warp thread II cannot reach below the middle shed line 18 in the binding point B, since it is prevented from doing so by the elongated eye 16 of the elongated wire strand Ol. As a result, the deficit SU is inevitably entered below the warp thread II.
• the upper compartment OF formed by the warp threads I and II looks similar to the upper compartment shown in Figure 1.
• the shaft strands 1 and 2 are in the representation according to FIG. 2 in opposition to the representation of FIG. 1, so that the warp thread II experiences the highest upper deflection and the warp thread I experiences the highest lower deflection.
• the warp thread I between the location of the elongated hole strand 02 and the stopper 12 moves below the elongated strand strand O2 the middle compartment line is hindered.
• the upper weft SO is only entered in the compartment formed from the warp threads I and II.
• the elongated hole strands XI and X2 shown in FIGS. 1 and 2 are shown in their lower end position, so that the elongated hole 16 incorporated in them permits movement of a warp thread III and IV guided through this upward only up to the middle shed line 18.
• the lower shed UF between the stop and the elongated strands XI and X2 is only penetrated by the lower weft due to this arrangement.
• the arrangement of the shaft strands 3 and 4 are shown analogously to the arrangements of the shaft strands 1 and 2 (in FIGS. 1 and 2).
• FIG. 1 and 2 show the production of a two-layer fabric, the upper fabric consisting of the warp threads I and II and the lower fabric consisting of the warp threads III and IV.
• the elongated stranded wires Ol and 02 work the middle of the slot SM deep> high (high pitch) and the elongated stranded wires XI and X2 work the middle of the slot SM high> deep (draft).
• Raising the elongated strands Ol and O2 means that the warp threads I, II are prevented from drafting into the lower compartment UF.
• Draft of the elongated strands XI and X2 means that the warp threads III, IV are prevented from going up into the upper compartment OF.
• FIGS. 1 and 2 show positions of the healds 1, 2, 3 and 4 analogous to the positions shown in FIGS. 1 and 2. Accordingly, the warp threads I to IV are guided high and low by the healds 1 to 4.
• all elongated stranded wires are moved into their respective other end positions. So now the elongated strands Ol and 02 are in their lower end position, so that their slot centers SM (middle of the elongated holes, see Fig. 5) are at the level of the middle shed line 18 and both warp threads I and II are the movements carried out by the healds 1 and 2 can be carried out completely and unhindered by the elongated wire strands Ol and 02.
• the slot wires XI and X2 are in their upper end position, so that their slot centers SM are also at the level of the middle shed line 18 and both warp threads III and IV can carry out the movements carried out by the healds 3 and 4 completely and unhindered by the slot wires XI and X2 ,
• the wefts OL and UL are therefore entered in the "full" shed, which takes up the space of the aforementioned partial shed OF and UF.
• a single-layer fabric with double weft insertion is consequently produced, that is to say twice as quickly as the previously described two-layer fabric produced simultaneously.
• FIG. 4 shows the positions of the healds 1 to 4 and thus the course of the warp threads I to IV in opposition to the representation according to FIG. 3.
• FIG. 5 shows an example (not to scale) of an elongated hole strand Ol with an elongated strand strand eye 16, which according to an advantageous development can have an additional regular eye 22.
