This invention relates to a warp stop motion, particularly of the dropper type, for automatically stopping the loom associated therewith upon breakage of a warp yarn.

The dropper type warp motion comprises droppers, each being suspended from a warp yarn by making use of the warp yarn tension and between the heald system and the back rest so that when a warp yarn breaks or loosens, the associated dropper falls under its own weight to cause automatic stoppage of the operation of the loom. In a known arrangement of the dropper type, when a dropper falls, an electric circuit is completed by the dropper and a contact bar which catches it, thereby automatically actuating a device which stops the loom. The plurality of contact bars are transversely supported between a pair of opposed side frames across the path of travel of the warp yarns.
