Abstract

A method of making a heald comprises producing a unitary metal blank having an elongated centrally located slot and forming a terminal eye at at least one end of the blank. Round steel wire stock is rolled to a flattened cross-section and longitudinal notches 9 are formed therein at regular intervals by tools (7), (8), Fig. 2 (not shown). The notches are expanded by a tool 10, which also places a thread eye insert member 12 in the slot so formed, the member 12 being subsequently secured as by soldering. Individual healds are separated by cutting the steel stock generally midway between the slots. To form a terminal eye 30 one end of a heald 41 is bent between movable pins 17, 18 and tools 15, 16. In second and third stages, the offset portion 19 is located between pins (171), (181), which correspond with the pins 17, 18, and the leg 21 is twice bent through 90 degrees by tools (22), (23) in succession, Figs. 6, 7 (not shown). The eyes 30 are additionally stamped to give them a precise inner shape. The heald may also be made from band steel stock and the terminal eyes are formed by punching a narrowed terminal portion (371) which is then bent to shape by bending in the direction of the larger crosssection dimension, Figs. 13, 14 (not shown).
