Abstract: A heald frame formed in a square configuration by joining a pair of frame staves forming the top and bottom frame members and a pair of side stays forming the right and left frame members has generally four flexibly constructed joint joints of the frame staves and side stay to prevent breakage which may result during the operation on a high-speed loom. A projection at the end of the side stay is disposed interiorly with a spacer mounted thereto within the hollow frame stave and then secured with the spacer which is depressed inwardly so as to have a deformed shape, whereby the projection of the side stay and the inner wall of the frame stave will be securely joined by the spacer.

Abstract: A heald frame for looms comprises a frame structure and support members which support opposed lateral edges of the frame structure. The support members, together with vertically reciprocating drive units connected thereto, are installed in the loop. The frame structure is adapted to be removably attached to the support members, so that the frame structure can be simply attached to and detached from the loom. Intermediate stays are attached at suitable positions and extend between the upper and lower frame staves of the frame structure, while elastic members are disposed between the respective connecting portions of the frame staves and side stays of the frame structure.
