A warp knitting machine in which the thread guides are held in tension by tensioning means and are supported in a common bar support, the thread guides belonging to one displacement row.

[0002]

2. Description of the Related Art Such a warp knitting machine is disclosed in US Pat. No. 2,534,
Known from No. 184. A plurality of blocks are secured to a continuous rail that serves as a common bar support.
The block has a slot in which a guide belt is guided. An extension is provided at the bottom of each slot so that the guide belt does not drop, and the thick cylindrical portion of the guide belt is guided in the extension. The rod driven by the handle mechanism acts on one end of the guide belt and the return spring acts on the other end. The thread guide is firmly attached to the guide belt.

[0003]

However, such a design has a relatively large depth and therefore has a corresponding installation space and a large weight, so that a defective part, for example, a guide needle, can be replaced. It is troublesome to assemble and rearrange, and only provides poor operability.

The object of the present invention is therefore to increase the operability and reduce the installation space and the weight of a warp knitting machine of the kind mentioned at the outset.

SUMMARY OF THE INVENTION According to the invention, the problem is that the motor support carries a servomotor for each guide belt and the tensioning means support is a tensioning means for each guide belt. And each guide belt is solved by having one connection at each of its two ends for detachably connecting the pulling element transmitting the displacement movement.

This design consists of three components: a bar support, a motor support and a tensioning means support, all of which can be prefabricated and first assembled on the warp knitting machine. I have to. All that is then required is to assemble the support at a suitable location on the warp knitting machine and attach the tensioning element to the connecting part of the guide belt. When the warp knitting machine is reassembled, the support can be installed in a new place as it is. Since the servomotor and the tensioning means can be assembled side by side relatively densely, and the servomotor originally occupies a smaller space than the patterning mechanism, the arrangement for the motor support and the tensioning means support is provided. The space is small.

The motor support preferably carries additional tensioning means for each guide belt. The tensioning means acting in opposition to this is such that the guide belt connected to the tensioning means is in a state of balance of force, and the servomotor connected to the tensioning means requires only a small operation force. Can be designed.

In a preferred embodiment, the motor support has a plate, which carries tensioning means on one side and a servomotor on the opposite side, the axis of which is on the plate. It has been inserted. As a result, a space-saving structural form can be obtained.

It is also preferred that a toothed belt is used as the tensioning element. As a result, the connection with the drive is virtually free of play and a more precise displacement of the thread guide can be achieved.

Another solution of the problem presented can also be applied together with the above solution, according to the invention the guide belts have their belt surfaces abutting each other and one surface of each guide belt is The part is exposed on one side, that is, on the operating side.

Since the guide belts are adjacent to each other,
Separate guides are eliminated, reducing installation space and weight. The exposed, ie, non-covered, surface area of the guide belt allows for operational comfort as described further below.

It is preferable that the guide belt has a slot and that the guide belt is supported by a common guide member of the bar support. This ensures that the individual guide belts are supported.

Advantageously, the guide belt has thin strips carrying the connections at both ends, the strips being:
All connections are offset from each other so that they are exposed on the operating side. All connections are exposed, ie not covered by other guide belts, so that the connections are easily accessible. The connection is made up of a simple hole into which a hook of the tensioning element or a connection pin can be inserted.

Edge areas of the surface of the guide belt are at least partially exposed, which edge areas are preferably used as connections for attaching the thread guide. This can be achieved very simply by the fact that the width of the guide belts decreases for each belt towards the operating side. With this design, all connections can be reached from the operating side.

Preferably, the guide belt carries two connecting members at each yarn guide connecting portion, and the connecting member is displaced in the direction of the handle portion of the yarn guide with respect to the other guide belts. As a result, a stable state is given to the handle portion of the yarn guide.

In a preferred design, the coupling member has a grooved pin, and the handle portion of the thread guide inserted into the groove is
It is gripped by covering a pin-shaped portion continuous to the groove bottom. As a result, the handle portion of the yarn guide is fixed so as not to be displaced in the direction along the belt surface of the guide belt.

It is also preferable that the handle portion of the thread guide is guided in the displacement direction by a part of the bar support. This guide prevents the yarn guide from moving in a direction perpendicular to the belt surface of the guide belt.

In a preferred embodiment, the bar supports have a back wall and two such bar supports are grouped into a pair of bar supports with the back walls next to each other. Therefore, a large number of handle guide bars can be accommodated in a very narrow space.

The bar support preferably has 4 to 12 thin guide belts. They can also be composed of other materials, for example carbon fiber reinforced plastics.

As another structure of the present invention, the thread guide is
It consists of a flat handle, a needle holder and a guide needle, which is firmly held by being elastically locked in the needle holder and is therefore replaceable. In this way, the guide needle can be replaced without opening the bar support.
