ABSTRACT:
In the loom, a thread guide channel is formed by upper plates and lower plates located in different cross-sectional planes of the channel. The lower plates are fixed to a sley, while the upper plates have their own guidance system formed in such a way that in each movement phase, points of the upper plates located furthest from the sley pivot point describe predetermined path lines which intersect the path lines of points on the lower plates furthest from the sley pivot point, so that during weft fastening the path line of upper the plates are at a smaller distance from the sley pivot point than in the weft insertion position of the sley. The upper plates are mounted on a pivot point on the sley and are pivotally connected by means of a connecting rod to another pivot point mounted extraneously of the sley.
Despite the smaller sley travel, an adequate spacing of the plates of the thread guide channel from the weft fastening during insertion into the shed is achieved.
