Abstract: A heald assembly of a loom, comprises a heald frame including two beam members which are formed with respective two inner faces which face to each other; two straight elongated openings formed respectively in the two beam members; two straight elongated slits formed respectively on the two inner faces of the heald frame beam members and merging respectively in the two straight elongated openings; a plurality of healds each having a heald body, and two installation sections secured respectively at the opposite end portions of the heald body, each heald installation section being located within the elongated opening and larger in width than the elongated slit; and a device for maintaining a damping-contact between each heald installation section and the heald frame beam member, thereby achieving weight and noise reduction of the heald assembly while maintaining secure connection between each heald and the heald frame.
