Coupled shafts on eccentric disks, each of which has a Linkage moves a shaft. The chronological sequence and type of movement of the shafts is the same in these well-known Runcwebstunien through the training of the curve boxes and, above all, only oie drive coupling of the individual eccentric disks lays that with curve boxes of a certain type only in each case eLr tubular fabric with a certain type of linkage (e.g. linen weave or woolen weave) can be produced can.

Xs ¹ - with these known round looms a change in the linkage of the tubular product produced is desired, all Kifvenkästen must be removed from the Rurdwebstuhi and replaced by other curve boxes adapted to the desired changed weave. Not only is this very time consuming, but it also means that for one. Runewebstuhl, optionally with the hose * "örmige i roducts are crforceriich. Leinenbindunc and with K-perbincung to be produced, two complete sets of cam boxes, what the actual Koster such a aundwebstuhls significantly increased.

The innovation lies in the task of creating a Runawe chair type described above while maintaining its basic advantage that several warp threads are the same with each shaft can be moved up and down in good time to the effect that there is no need for major retooling and, in particular, also without replacement from curve boxes a change in the weave of the fabric produced sch] cake-like product is possible.

To solve this problem, a circular loom of the type described above is designed so that each Scixft has its own drive element and the drive elements of all shafts are actuated by signals supplied by a control or drive device.

The design of a circular loom allows the shafts to be controlled by an electronic device

7821980 01/25/79

to carry out the supplied program, with any desired Weave by simply switching the thread is manageable, without; that extensive mechanical changes to the circular loom are required.

In the round loom according to the invention, the shafts are preferably as flat or slightly curved plate-shaped elements formed, which as strands or as facen-leading openings several have parallel slots. In particular, the circular loom in accordance with the revision can be designed in such a way that that all shafts have the same design, whereby By using many similar elements, both the production and repairs can be made much easier will.

The drive -: es webs <~ hützes occurs with the new: gemäfien Circular loom, preferably in that an electromagnet is provided on a suitable support, which extends along the Moved guideway and its magnetic field via a magnet armature provided on the weaving gate this weaving gate.

Compared to other previously known drive methods for the web shuttle, this results in significant advantages, since, for example Computationally heavy and complicated partsV7üe push blocks that were customary up to now are avoided. In addition, the drive has of the web guard with the help of an electromagnet compared to other purely electrical ones. Drive methods (e.g. linear motor) advantage of a very simple structure and low energy consumption .

As already mentioned above, a separate drive element 34 is provided for each S-chatt 3 jin. In a similar way, each shaft 3 'and 3''has its own drive element 34'
and 34 "(Fig. 5). The drive elements 34, 3 <, 'and 34" are sine
Connected via lines to the outputs of a control device 40 which, depending on the design of the drive elements 34, 34 ',

To cen steurtechr.ischen effort th low as possible to ha ^1, it is convenient to de drive elements of several on a ar. the f oicen—
of the sectors to be connected in parallel and to be connected to a common input of a control device 41. The same applies to the drive elements 34 'and 34 ".

In FIG. B, for the sake of simplicity of illustration
It was also assumed that the control device 41 has only three outputs. However, it is also possible to design this control device in such a way that it has several groups of three outputs each, with each group then having a drive element 34, 34 'or 34 "or 2 or also with each output
