Establishment of .first and Yerfa jiries for the production of fourf? s

The invention relates to a device and a method for producing vierfädigen. Knotless braided nets based on the four-wheel principle *

There is already a device 1st aur production _{vierfädiger?} Knotenlos braided Wetze known (DD-PS 30922, 43176 and 86061) "It is designed in this way; that for the production of the network legs a plurality τοη braiding heads is provided side by side j which consist of four square arranged Jlügelrädern (four-wing principle) «

On each of the four impellers braiding heads made the production of the network leg by circulation of four bobbins in diagonally arranged eight-shaped paths «The impellers are provided with four rectangular sections for receiving and transporting the clapper.

In order to establish the connection point between adjacent network branches, there are provided switches between the impellers of the adjoining floor headers? about the transferring '

the clapper is made from one braiding head to the adjacent braiding head «. ...:. "

Due to the arrangement and number of impellers in Tierflügelradprinzip'und by the formation of the impellers with four cutouts are for the preparation of 'a lichen in Netzschenkel.acht steps or''90 ° turns, the impellers required »The same number of steps is for the production of the joint is necessary * Is also a gate direction for producing vierfädiger, knotless braided nets (DD-PS 103 282) known in which the individual braids for the production of the network legs of three impellers consist (three-impeller principle) «The production of the network leg on a Braiding head is made by circulating four pairs of bobbins arranged in pairs according to a specific pattern * Each impeller has four right-angled cut-outs for the clappers * Due to the arrangement and number of impellers in the three-blade principle, braiding is done in a square cord Twelve steps or ₀ 90 rotations of the impellers required "The connection point between the mesh legs can be produced in three steps"

Summing up the state of the art, the advantage of the animal-flywheel principle over the three-worm wheel principle is the lesser number of steps required to make a braid in the net leg (eight compared to twelve). "The disadvantage is due to the higher number of vanes (four in comparison to three) _f apart from the resulting higher technical effort *. _v

Lm. With regard to the connection point, the disadvantage of the Tierwradradprinzips compared to the Dreiwügelradprinzip in the higher number of.Schritten for the connection point (eight compared to three) «''

One can therefore conclude that the Tierflügelradprinzip for knotless braided nets with large mesh sizes (long network legs, little joints) and the three-wheel principle for short network legs and many joints is advantageous «'' ·" '· ·.

The invention "is intended to ₅ ye rf ahrens technical effort to produce the Netzsc.henkels and the junction of knotless braided networks naoh the Vierflügelradprinzip to reduce"

The invention has for its object to provide a process for the production of vierfädigen, knotless gefJ 'wuchten networks au by which the technical complexity of each impeller and the economic cost of producing the joint are reduced on the condition that receive the Quadratkordelform of Netaschenkels remains"

The device for producing four-ply, knotless braided nets based on the Vierflügelradprinzips according to the invention is characterized in that the four impellers of each braiding are squareförmig 'and each impeller' three provided at an angle voni20 ° cutouts «. , , , '

The method for producing vierfädigen ^ knotless braided nets on the three-impeller principle according to the invention is characterized in that for the production of the net leg two pairs of bobbins in the diagonal crossing, eight-shaped paths of a braiding head wicker and circulating for the preparation of'Verbindungsstelle the clapper over between Switches from one Fleohtkopf to the adjacent braiding head provided for the vanes of adjacent braiding heads »

The method is further characterized in that the diagonally crossing, eight-shaped tracks of a braiding head are formed by the diagonally opposite impellers and in each eight-shaped track, a pair of towers revolves »The bobbin position is in" each braiding head during manufacture "of Netzschenkels- and the joint, 'so that an IO-öppelstellungsversatz on the Siidflechtköpfen deleted «

By virtue of the invention, the door part of the four-impeller principle, the three-impeller principle - small number of steps for making a braid in the net leg - is used in conjunction with a reduction in the steps of "eight to five steps in making the joint" Advantage of the proposed device according to the invention "is _? that for each impeller only three cutouts for receiving and transporting the bobbin are necessary (the four-wing principle four cutouts per-impeller necessary) "Due to the lower technical complexity per impeller there is the possibility to use _s larger coils with a higher capacity «. ..

The invention will be explained below with reference to the embodiment described in the drawings. Show it:

FIG. 1: braiding head and the steps for producing a braid in the wetzschenkel

FIG. 2 shows two adjacent braids and the steps for producing adjacent braids. FIG

Fig. 3: two adjacent braids and the "Steps for making the joint between adjacent net legs

Fig. 1 shows in the upper part of the braiding .10, which is composed of four dromatically arranged Flügelrädern .11j 12, 13 and 14. 'Each impeller has three in Y / inchel of 120 ° provided cutouts 15 on über.die the recording and The bobbins 1 and 2 run in the aohtförmigen path formed by the impellers 11 and 13 and the bobbins 3 and 4 in the path formed by the impellers 12 and 14 in order to pass through the Diagonal Verkrsuzung the with the Hoppeln, running thread develops the. so called,. Square cord «, The direction of rotation of the Flügelrad 11 to 14 is indicated by arrows.

In the lower part of Fig. 1 (a - f), the steps, ie 120 ^ό ~ rotations of the impellers, for the preparation of the network leg shown »Wach, six steps is a lichen in the. Netzschenkel produced and the clapper have their initial position again occupied

Compared to the well-known four-impeller principle, the proposed principle is characterized by the fact that the smaller number of cuts, per section per impeller longer ways and thus higher running speeds are possible «

In Fig _e 2, one of the two braids 10 and 20 existing braid unit is shown. The braided heads are arranged to each other so that each two impellers 13 _? 14 and 23 ,. Tangent to 24 adjacent braids *

In the lower part of FIG. 2, the stepwise production of the two adjacent net skeletons is represented by six 120 ° rotations of the vanes.

Figure "3 refers to the preparation of the junction of two adjacent mesh side" The starting position of the clapper in the upper part of Figure 3 corresponds to _e st RECOVERY in oberen'Teil the KLb'ppelausgangs, the Pig * 2. The transition of the clapper from a braiding to adjacent braiding occurs in the formed of the vanes, eight-shaped paths. From the stepwise representation according to FIGS. 3 a to 3 e it can be seen that the production of the connection point is completed after five steps and the sixth step is already the first step for the subsequent production of the network legs.

The advantage of producing the joint based on the principle proposed by the invention is that. compared to the well-known four-wing wheel prinsip, the number of steps for producing the connection point is reduced from eight to five »
