This International Standard applies only to drop wires that are drawn in by hand or pinned by means of a pinning machine. It applies to the following types of drop wires: a)formechanicaland electromechanicalwarpstopmotions MG (closed end) MO (open end) b) forelectrical warp stop motions EG (closed end) EO (opcn cnd) Dimensions 2.1 The dimensions for drop wires type MG and MO for mechanical and electromechanical warp stop motions are given in tigure 1 and table 1. 2.2 The dimensions for drop wires type EG and EO for electrical warp stop motions are given in figure 2 and table 1.
