Abstract

The invention relates to a method for producing vierfaedigen, knotless braided nets using the Dreichtegelradprinzips. The purpose of the invention is to improve the Kloeppellauf on the Flechtkoepfen for the preparation of the net legs and thus reduce the oeconomic effort to produce the joint. The object of the invention is to provide such a method by which a gleichmaesziges, symmetrical braid is made. The object is achieved according to the invention by starting from a Kloeppel position in the braiding for the production of the network leg, in which every third section of the wicker trajectory is occupied by a Kloeppel, and between the Kloeppelstellungen adjacent Flechtkoepfe an offset by a braiding step (90 degrees ) consists. In an offset of Flechtkoepfe to a Fluegelrad is assumed that the same Kloeppelstellung in each braid.

Process for the production of four-thread, knotless braided nets

Field of application of the invention

The invention relates to a process for the production of four-filament, knotless braided nets, which are braided according to the three-impeller principle.

Characteristic of the "known technical solutions

It is already a device for producing four-strand knotless braided nets (DD-PS 103 282) is known in which the individual braids for the production of the network legs of three vanes exist (three-impeller principle). The axes of the impellers of a braiding are either at right angles to each other or on a straight line · The production of the net leg on a braiding is done by circulating four bobbins, which are moved in a certain pattern by the rotation of the impellers in achtförraigen trajectories · To produce a Lichen in the network leg requires six steps or · six 90 ° revolutions of the clappers. After twelve steps, each bobbin has once again reached its starting point ·

For the preparation of the connection point between adjacent network legs turnouts are provided for the exchange of bobbins from one braiding to the adjacent between the vane wheels of adjacent braids · For the preparation of the connection point with the device described in DD-PS 103 282 twelve steps are required · To the economic Various solutions have already been proposed for reducing the connection point (WP DO 4 C / 219 260).

The investigations into the three-impeller principle have led to the finding that the quality of the braid and the economic effort for the preparation of the joint is determined by the initial position of the bobbins on the braiding heads.

In the patent application V / P DO 4 C / 217 383 it is assumed that a starting position of the bobbin on the braiding head, in which each pair of bobbins runs in an eight-shaped path, the middle of the three impellers shared by the eight-shaped paths of both pairs of bobbins This lace runner reduces the cost of making the net leg from twelve to eight paces. The disadvantage of this Klöppellaufs is that the resulting mesh has textile-physical deficiency.

In the DD-PS 103 282 and in the patent application WP D 04 C / 219260 Is assumed from a starting position of the bobbins on the braids, in which the bobbins are also arranged in pairs, but the bobbin runs in the braided tracks formed from the three impellers , The disadvantage of this Klöppellaufs is also in the textile-physical properties of the braid.

Object of the invention:

The invention aims to improve the bobbin run for the production of the net leg and thus to reduce the economic effort for the preparation of the joint.

Explanation of the essence of the invention

The invention has for its object to provide a method for producing vlerfädlger, knotless braided nets, through which a uniform, symmetrical braid can be produced.

The object is achieved in the method according to the principle Dreiflügelrad, according to the invention that is assumed for the production of the network leg of a bobbin position in the braiding, in which every third section of the wicker web forming impellers is occupied with a clapper, and between the bobbin pitches adjacent braids Offset by one braiding step (90 °). Another feature according to the invention is that when the braiding heads are displaced around an impeller, the braiding position is assumed to be the same in each braided head.

The invention makes it possible to produce a symmetrical and therefore stronger mesh. The clutches change in the production of the connection point on the shortest paths, whereby an economically rational production is ensured ·

Pig · 1 shows the section of a braiding device in which the two braided heads 1 and 2 each consist of three vertically adjacent impellers 3, 4, 5 and 6, 7, 8 (three-impeller principle). The direction of rotation of the impellers is indicated by arrows. Each impeller is provided with four mutually perpendicular cutouts 9, which serve for receiving and transporting the clappers 1 ¹ to 4 ¹ and 5 'to 8' during the braiding process. The braiding head 1 is occupied with the bobbins 1 'to 4' and the braiding head 2 with the bobbins 5 'to 8 ¹ . The clappers run in the Flechtbahnen formed by the impellers 3, 4, 5 and 6, 7> 8. According to the invention, the clappers 1 ¹ to 4 'and 5 ¹ to 8 ^{1 are distributed} on the braiding heads 1 and 2 so that of the twelve existing vane cutouts 9 every third cutout is occupied «

The stepwise production of the network legs is shown in the subfigures 1 a to 1 f (a braiding step equal to a 90 ° rotation of the impellers), After six steps, a braid is made and after 12 steps, the clappers have the starting positions on the braids heads 1 and 2 taken ·

2 shows the section of a braiding device for producing the connection point between the adjacent braiding heads 1 and 2. The bobbin positions between the two braiding heads are offset by a braiding step of 90 ° to each other. The stepwise production of the connection point can be seen from the partial figures 2 a to 2 f. After six steps, the clappers 1 'to 4 * of the braiding head have assumed a position corresponding to the starting position on the braiding head 2. The same applies to the clappers 5 ¹ to 8 ·.

Fig. 3 also shows the detail of a FIeinrichtung for making the connection point between the adjacent braids heads 1 and 2. The bobbin positions are the same on both braids heads, between the braids but an offset is provided to an impeller. The gradual
