Definitions
- the invention relates to a method and a device for the manufacture of textile net-like fabrics by various consolidation methods, for example the warp or sewing method.
- nets are usually manufactured using known knitting or knitting machines using knotting hooks or using known warp knitting or sewing machines using latch needles or pusher needles.
- the disadvantage here is that the product width is determined by the working width and the network opening structure, the structure variable
- the welding sword determines. Furthermore, only the processing of thermoplastic material is possible due to the selected solidification process, so that the product is limited in its possible uses.
- Sewing-knitting machines are also known, on which square-mesh networks can be manufactured with weft threads running transversely to the processing direction (DD 269298).
- parallel weft threads are fed in transversely to the processing direction and pierced in the work station * at certain intervals transversely to the processing direction of work organs forming stitch sections and tied or bound in by means of sewing threads looping around the warp thread.
- REPLACEMENT LEAF The disadvantage here is that the size of the mesh openings, which is determined by the distance between the supplied weft threads or the distance between the wales forming working organs, cannot be changed. Furthermore, the maximum product width is equal to the working width and the strength of the products is low due to the fact that point needles not involved in stitch formation pierce the weft thread template.
- the object of the invention is to provide a method and a device for carrying out the method according to various consolidation methods, primarily the warp or stitch-knitting method, for the production of textile, net-like flat structures with the net mesh legs continuous in and transversely to the direction of processing forming threads, with large mesh opening width, high structural variability and product widths that go beyond the working widths.
- FIG. 1 Schematic representation of the process steps:
- Fig. 3 Schematic representation of the process step: incorporation or connection of the functional thread to the
- REPLACEMENT LEAF Fig. 4 Schematic representation of the process step: start of laying the functional thread
- Figures 1-4 show a schematic representation of the method steps according to the invention.
- the schematic representation in FIG. 1 shows that the functional thread 11 is already integrated into the adjacent side net thread groups 14 forming the net stitch legs in the processing direction.
- the net leg thread groups are formed from warp threads 4.
- the next functional thread is guided from one long side of the fabric to be produced to the formation of the other net mesh legs lying transversely to the processing direction to the opposite long side.
- the functional thread is temporarily fixed at several points and is looped between the fixing points to form a functional thread reserve.
- the schematic representation in FIG. 3 shows that the selected function thread 11 is simultaneously led to the net thigh thread groups and is connected or bound by means of the warp threads. After the attachment or integration, the temporary fixation is released.
- the functional thread in this method step, can be fed in over the entire width and the connection or connection in one work cycle.
- the feeding of the functional thread and the incorporation or connection are distributed over several work cycles, so that a staggered, temporary work edge is created in the manufacturing process during the work process.
- a functional thread reserve is understood to be a loop-shaped thread reserve in the functional thread system which is built up during the formation of a textile network in the stitch formation process and which can be eliminated by transferring the textile product from its production position into the position of use (spreading).
- FIG. 4 shows how the functional thread is guided to the output longitudinal side in accordance with the method step illustrated in FIG. 1 for forming the next mesh stitch leg.
- the method according to the invention it is possible to lay and cumulate one or more functional threads and then to tie or incorporate the functional thread or threads simultaneously in one or more working games. Furthermore, it is possible not to deflect the functional thread between the fixing points and / or by the same and / or by different amounts, the next functional thread in the processing direction also not being deflected to the previous functional thread and / or by the same and / or different amounts can be.
- the formation of the net leg thread groups and the connection and / or connection takes place according to the warp knitting method from at least one warp thread, it also being possible to form the net leg thread groups according to the warp knitting method from a warp thread and a standing weft thread.
- the formation of the net leg thread groups and the incorporation or connection can also take place according to the known sewing method from at least one sewing thread or from at least one sewing thread and at least one standing weft thread.
- the net leg thread group and the binding in or connection can be formed from at least one warp thread according to the known net knitting method.
- the connection and connection can also be carried out thermally or chemically.
- an endless functional thread as shown in FIGS.
- SPARE BLADES s.tellt or a finite functional thread, which is separated from the functional thread supply spool 12 on each long side. For this it is necessary that the loose end is temporarily fixed on the long side.
- FIG. 5a-h show product examples in the production position and in the use position.
- FIG. 5a shows a product example in which the last functional thread was not deflected transversely to the processing direction at first, then by a small amount and finally by a larger amount different from the previous amount.
- the subsequent functional threads are deflected transversely to the processing direction and also in relation to the functional thread preceding in the processing direction by different amounts, the amount also being zero. It can be seen that any conceivable network structure can be reached through the different deflections transversely and in the processing direction. It can also be seen that a network width that is above the working width can be achieved.
- the warp knitting unit consists of a plurality of jointly movable pusher needles 1 which are combined on a needle bar and each of which a locking wire 2 is associated with, from one or more thread guides designed as laying rails, with thread guiding elements for the warp threads 4 mostly designed as perforated needles 3, and one between the sliding needles 1 arranged milling plate 5 as well as the piercing comb 6.
- the warp knitting point is assigned a functional thread insertion system acting via at least two sliding needles 1 lying next to one another transversely to the processing direction.
- it consists of a plurality of bars 7, fixed in a row on a bar 7 which extends transversely to the processing direction over the entire working width of the machine, rotatable about its longitudinal axis and horizontally movable perpendicularly to its longitudinal axis 8 trained elements for receiving the functional thread and for fixing the functional thread reserve
- the function thread reserve formation system 9 is assigned a rotatably attached function thread guide 10, which is rotated in the direction of movement of the function thread reserve formation system 9.
- the functional thread reserve is formed during the movement rest by lowering the element for functional thread reserve formation 13.
- the element for functional thread reserve formation 13 is associated with a drive designed as a transmission and this with a pattern control, the pattern control correlating with the controls of the other elements and systems of the device.
- the invention is equally applicable to warp knitting / sewing knitting work stations with two needle systems or with knitting needles designed as tongue or point needles.
- FIG 7 shows a front view of the functional thread insertion system with the functional thread reserve formation system 9 at the time of the thread reserve formation between two sinkers 8.
- FIGS. 1 to 4. 1 to 4 the work location is shown schematically in plan view. 1 shows the functional thread reserve formation system 9 when the functional thread 11 is placed by means of the functional thread guide 10 in the sinkers 8 of the functional thread insertion system, the temporary fixation of the functional thread 11 in the sinkers 8 and the functional thread reserve formation taking place in the process (FIG. 1 corresponds to FIG. 7 in plan view) ).
- the slide needles 1 are located at the rear dead center, so that the needle heads are below the upper edge of the milling plate 5.
- the functional thread reserve formation system 9 is in the waiting position outside the work area and the functional thread guide 10 has already been pivoted through 180 ° in the subsequent direction of movement.
- the piercing comb 6 moves horizontally backwards out of the working position and the bar 7 with the plates 8 which have temporarily fixed the functional thread 11 with the functional thread reserves , moves horizontally into the work place.
- the functional thread reserves are raised above the upper edge of the milling plate 5 by a rotational movement of the bar 7 about its longitudinal axis and brought to the back of the milling plate 5 by pivoting the bar 7 back.
- the functional thread 11 with the functional thread reserve is located between the back of the slide needle and the warp thread 4.
- the sinkers 8 take over the task of the piercing comb 6.
- the bar 7 moves horizontally out of the work area, the piercing comb 6 again horizontally into it, the warp threads 4 are placed on the fringe and knocked off.
- the functional thread 11 is thus tied.
