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.

Heald assembly of loom

A weft detaining device of a shuttleless loom, including a drum having a frustoconical section and a cylindrical section, a first catching member for catching the weft yarn on the drum in the vicinity of the border between the frustoconical and cylindrical sections for at least a period of weft pickings, a second catching member for catching the weft yarn on the drum for at least a period of the first time weft picking in sequential twice weft pickings and releasing its catching action to the weft yarn for at least a period of the second time weft picking of the sequential twice weft pickings, and a third catching member for catching the weft yarn on the drum cylindrical section for at least a period wherein the detaining of the weft yarn for the succeeding twice sequential weft pickings is completed, thereby enabling a so-called dual-pick pass weft insertion though the weft detaining device is of the drum type.

Weft detaining device for shuttleless loom

Straight and arcuate members define an aperture through which a weft yarn is carried by a jet stream of pressurized air. The leading end of the arcuate member closely approaches the straight member to form an exit slot through which the weft yarn is permitted to pass on exit of the same. A flat spring member is arranged to extend from the arcuate member toward the straight member to close the exit slot and is provided with a screen which fluidly seals the space between the flat spring member and the arcuate member.
