TRAINING DEVICE FOR WEB MACHINES

Priority dated September 18, 1970 USSR No. 1477602

The present invention relates to looms, in particular on shedding devices, which are in these weaving machines are used.

The present invention can be most advantageously used in i7el? nia3chincn with multiple subjects are applied that Create fabrics of different articles.

At the present time, shedding devices are known which contain systems of shaft supports, which carry bars with vaults for the passage of warp threads and which receive their reciprocating movement from an angled lever which swivels on an immovable axle.

is arranged.

In the device mentioned, each shaft is supported as one part is executed and supports a rigid "fixed frame" with 'tfeblitKen (see for example the BHD patent IO72569 from 1956).

In the mentioned devices it is made possible by the presence of shafts made as one part are, not, the position of the subject in relation to the fabric and consequently to regulate the tension of the warp thread, 'what at It is necessary to switch to another article of the au generating fabric; otherwise the "changing the sentence" is the Shaft butts required.

The aim of the present invention is elimination the disadvantages mentioned above.

The invention is based on the object of developing a shedding device that makes it possible A wide range of different fabrics can be created and changed by regulating the position of the compartment of the profile of the shaft, which is formed by warp threads.

The problem posed is achieved in that in the Fachbl dung s ν or direction, which contains systems of shaft supports, the strips with wobbles for the passage of warp thread wear and receive their reciprocating movement from angle levers on an immovable axis

are arranged according to the invention "

; i . Ck **

Each shaft support consists of two mutually overlapping ends which are movably connected at their free ends with an angle lever and the strips, the mentioned parts of each support being displaceable relative to one another to change the position of the compartment in relation to the fabric edge and a smock for fixing the same included in the given position.

This constructive solution allows e3, a tissue breitos range thanks to the mutual displacement of the parts of a support shaft to change. . the position of the fac .: in relation to the tissue edge and thus

the tension of the branches of the shed formed by warp threads. It also makes it possible that3

to set the required profile of the specialist shaft.

Each part of the shaft support is expediently provided with teeth on the inside at the point of overlap, which mesh with one another in a rack and ensure the mutual displacement of the parts. one of the parts having a bore and the other having a hat for the retainer to pass therethrough.

For a better understanding of the invention, an exemplary embodiment is considered below with reference to the accompanying drawings; in the drawings shows:

General description of the structure of the specialist training device

The shedding device contains systems of shaft supports with healds 1 (Fig. 1, 2) for the passage of warp threads 2, each shaft support consists of two mutually overlapping parts 3 and 4, each with their free ends with an angle lever 5 of an eccentric drive 6 of this device and are movably connected to strips 7 which carry the weblits 1. The levers 5 are pivotably arranged ^{on an axis 8 1.}

The mentioned parts 3 and 4 of each support are to the amazement of the position of the compartment with respect to the fabric edge against each other arranged displaceably and contain a means 8 for fixing the parts 3 and 4 in the predetermined

Location. The shaft supports move in guides 9, which are arranged on V-angle * 10, those on the frame of the loom "are attached.

Detailed description of the components of the technical training device

The fixation means 8 contains a holder which is in. Shape of a form screw 11 and a nut 12 is made, each shaft support on the overlapping parts inside has teeth 13 which come into rack engagement with each other and the mutual displacement allow the parts, where

one of the 'feile a bore 14 and the other _e ine hat 15 has to pass the fixed holder therethrough.

7 can either be rigid on the shaft supports, as shown in FIG. 2, or articulated, such as it is shown in Fig. 4, be attached.Depending on this form from the warp thread 2 shed waves Profile step-shaped, as shown in Fig. 3, or continuous, as can be seen from Fig. 5, is formed.

Function of the shedding device

Takes place before the technical training device is started the setting of the multi-compartment weaving machine. The warp thread 2 are drawn into the healds 1 (Fig. 6) * Depending on the Article of the fabric to be produced becomes the required

Location of a compartment in relation to a fabric edge 16 of a fabric 17 and the corresponding tension is set on the branches of the shed, which is necessary for tissue formation. The required position of the compartment is achieved by moving part 3 of the shaft support over part 4 of this support with subsequent fixation of these two parts

by means of

the screw 11 and the wires 12, as well as the. teeth 13, which come into rack engagement with one another, are set at the "overlap points of the shaft supports".

When the drive 6 is working, the movement is transmitted to the y-arm levers 5 and via these to parts 3 and 4 of the shaft s, which, by executing a reciprocating movement with a phase shift, imitate a wave-like movement, which in turn is given the warp thread 2, ie the set position of the shed , via the strips 7.
