Abstract

A spreader tool for the individual coupling and decoupling of heald shafts to or from the respective drive rods or shaft pulls of a heald loom is constructed to be inserted into a gap between two connecting spring sections from above the loom healds for spreading the connecting spring sections apart. The tool has two jaws that are normally biased into their closed position by a spring for insertion into the gap and are then spread apart by a cam drive or the like. The assembly and disassembly is thus greatly facilitated and the time previously required for this type of work has been substantially reduced.
