Abstract

A travelling-wave loom comprises a rotary reed. The rotary reed includes a shaft with disks angularly offset relative to one another and provided with teeth of different radial lengths. The disks are mounted on the shaft in groups of at least two disks. In one disk of each group, in the direction of the reed rotation, at least one of the teeth is located relative to the corresponding tooth of the other disk of each group so that a helical line formed by the front edges of these teeth is of a step-like shape. Such an arrangement of the disks and the teeth thereof creates favorable conditions both for reliable engagement of the weft and for advancing the latter to the fell of the cloth for subsequent beating-up.

Claims6

Dependent claims

In a travelling-wave loom having a plurality of weft thread carriers, a rotary shaft;

disks fixed to said shaft for rotation therewith;
said disks forming groups each including at least two disks, said disks having teeth of different radial lengths arranged in increasing order of radial length in the direction of rotation, said disk teeth having front edges and said disks being angularly offset relative to one another with said teeth thereof forming parts of helicoids, one of said teeth of each disk engaging the weft thread as soon as the latter emerges from the weft thread carriers, at least one of the teeth of a disk of each group being located relative to the corresponding tooth of the other disk of each group in such a way that a helical line formed by front edges of these teeth has steps.
