Description

Xnote-free fish net The achievement concerns a bond pattern, which enables from a multitude of endless threads a knotless fishing ,. to establish a network. It was primarily concerned with processing made of yarns, twines, etc. from synthetic fibers, thought. The well-known fishing nets are all represented in such a way that the mesh threads are connected by knots at the crossing points are bound, which, especially in the case of close-meshed networks, have a high 8 Cause weight and undesirable material consumption. the Net tying machines work with contactor coils, which in particular which can take up little yarn in heavier nets, and therefore have to be replaced very often, which leads to undesirable downtime de has the consequence. The network construction described below can be kneading machines (e.g. the Raschel machine. These machines have a high production capacity, which is several times that of the known net knotting machines. The material expenditure caused by the mesh can be compensated by inserting working thread so that the total weight of the net is below that of the knotted remains. The braid that represents the net thread is one of two Single thread existing double stitch row in the according to Fig. 1 of the Single thread is pulled through the stitch of the next thread ' This type of binding has the advantage of greater security in that if the thread breaks, the formation of ladder stitches is made much more difficult.

Since the graphic representation of the crossing points, as handled in Fig. 1, is confusing, a schematic table representation (Fig. 2) passed over, b / a means dasa der Thread b pulled through the loop of thread a.

At the crossing points there are now several possibilities of connection, which are fairly equivalent in terms of their strength and also security against opening in the event of thread breakage. Quenching this "knot is practically impossible. The Coupling itself takes place by swapping the feed threads.

Figs. A, B, C, D show such connection possibilities for the production of the crossing points, whereby not all possibilities of the coupling are shown. Of four feed threads a, b, c, d running next to one another, only a, b and c, d are coupled with one another according to the scheme before and after the crossing point abcd ba de from cd which can also be read in such a way that z. B. in the second line of thread b through stitch a, thread a through stitch b, etc. is pulled. So it is always in the line about which stitch the thread has been pulled through. The following picture emerges for Fig. A. lab cd uncoupled ... dabc 1st coupling / cdab 2. bcda 3. " abcd 4. " badc uncoupled As you can see from Fig. A, the connection of this crossing point is eight-stranded over four steps, and also asymmetrical, which requires that all four aden be led individually. The latter also applies to all other types of binding.

Figs. B and C are symmetrical couplings and the connection via four steps 16-ply. Fig. D is a symmetrical eight-strand connection. The above four step 16-ply connections are in each case more durable and because of the For durability, it is also impractical to try to get by with just two steps.

Finally (Fig. E) there is the possibility of so-called half-connections, where only two of the four threads are used to establish the connection will. Here, too, you can achieve an eight-wire connection in four steps.

For the sake of completeness, Fig. F shows an excerpt from the Overall network.

The following claims for protection are derived from the above examples :
