Abstract
The warp yarn stop motion is provided with a locating rail which is sub-divided into electrically insulated sections from the U-shaped rail. Each of these sections is electrically connected with pilot lights at the ends of each section. Should a drop wire fall on to a rail section, the pilot lights at the ends of the section are also illuminated so as to define the segment of the weaving width within which a broken warp yarn is located.
Claims10
In a warp yarn stop motion, the combination of:
- a first substantially rectilinear supporting rail;
- a second locating rail mounted on said first rail in electrically insulated manner, said rail being sub-divided into at least two electrically insulated sections;
- a plurality of drop wires mounted over said rails, each said drop wire having at least a pair of surfaces for contacting said respective rails to complete an electrical circuit therewith;
- and
- a plurality of signalling means, each said signalling means being electrically connected to a respective insulated section.

A warp yarn stop motion comprising:
- a first substantially rectilinear supporting rail;
- a second rail mounted on said first rail in electrically insulated manner, said rail being sub-divided into at least two electrically insulated sections;
- and
- a plurality of visual signalling means, each signalling means being mounted at an end of a respective insulating section for emitting a visual signal in response to said first rail and a respective insulated section of said second rail adjacent said respective signalling means becoming electrically connected to each other.
