Abstract
Abstract The present invention relates to devices for holding an end of a weft thread and may be most effectively used on looms wherein the beating-up of the weft thread is performed by beat-up elements. This device includes two groups of shaped plates with notches and projections installed at each selvage of the cloth, the plates of one group being arranged closely adjacent the plates of the other group so that the projections of both are arranged against one another, thereby forming a gap for receiving the weft thread which frictionally engages the projections. Due to such an arrangement, sufficient braking of the weft thread and, consequently, reliable prevention thereof from axial displacement are ensured.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
A device for holding ends of a weft thread on a loom having a rotary shaft carrying beat-up elements, comprising: two groups of shaped plates arranged in planes perpendicular to said rotary shaft opposite one another, installed on shafts adjacent each selvage at the fell of the cloth, each said plate having a notch and a projection, said plates of at least one of said groups always occupying gaps between the beat-up elements of the loom; said plates of one group being arranged closely adjacent the plates of the other group so that their projections are also arranged closely adjacent one another forming there between a gap of less width than the thickness of the weft thread wherein the weft thread frictionally engages the projections of the plates, as a result of which the thread end is frictionally held at the selvages of the cloth.
Claim 2
Independent Claim
145 words
A device for holding ends of a weft thread on a loom having a rotary shaft carrying beat-up elements, comprising: two groups of shaped plates arranged in planes perpendicular to said rotary shaft opposite one another, installed on shafts adjacent each selvage at the fell of the cloth, each said plate having a notch and a projection, said plates of at least one of said groups always occupying gaps between the beat-up elements of the loom; said plates of one group being arranged closely adjacent the plates of the other group so that their projections are also arranged closely adjacent one another forming there between a gap of less width than the thickness of the weft thread wherein the weft thread frictionally engages the projections of the plates, as a result of which the thread end is frictionally held at the selvages of the cloth.
Claim 3
Dependent Claim
21 words
A device as claimed in claim 1, wherein thread projections of the plates of each group are provided with parallel bevels.
