The heald frame made of double wire has elongated ears at its ends to receive the heald frame, and wire eyes are provided between these ears. The ears at the ends of the healds are formed by bending double wires and wrapping the ends around the shaft and fixing them to the shaft by welding.

The disadvantage of these healds is that the lugs are thicker than the twin wires and therefore take up too much space when juxtaposing the healds on the heald rods, thus also increasing the overall weight of the healds. Furthermore, in such a construction, due to some thickening, the healds may jam and remain in the air when the shaft is raised or lowered, interfering with each other's correct intended movement.

The heald frames are arranged such that the bent ends of the wire parts engage in correspondingly shaped grooves in the small plate, and these parts of the wire are connected to the small plate by welding such that the healds are located at most not far from the connection point of the heald shaft to the steel plate. Will be thicker than the normal thread of the spool.
