Embodiment Construction

[0028]FIG. 1 shows a heald frame 1 having an upper, generally horizontally arranged heald frame plate 2 and a heald frame plate 3 fastened parallel thereto at a distance. The heald shaft plates 2 , 3 are connected to one another at their ends by side supports 4 , 5 so that together with the heald shaft plates 2 , 3 they form a rectangular frame. A plurality of healds 6 arranged parallel to one another are arranged in the frame and are each provided with a thread guide eye 7 for guiding a warp thread. The healds 6 arranged parallel to the side supports 4 , 5 each have a heald lug at their upper and lower ends, with which they are fastened to a heald rod 8 , 9 . The heald rods 8 , 9 extend parallel to the respective adjacent heald frame plates 2 , 3 and are held at a distance therefrom. Connecting devices 11 , 12 , 13 , 14 are used for this purpose, and they respectively form a releasable connection between each heald frame plate 2 , 3 and the heald rods 8 , 9 assigned to the h...

Abstract

Holding devices are provided for detachable fastening heald carrying bars (8) on heald staves (2) of a shaft (1) of a weaving machine. These holding devices consist of, for example, two metal sheets of which one part forms an adhering surface for joining to the heald stave (2). The remaining part serves to accommodate metallic reinforcing strips (rib (31, 32)) that can be riveted or welded to themetal sheet. These reinforcing strips serve to accommodate fastening elements for a plate and to position this plate. The positioning is realized in a positive manner. The metal sheets are preferablytightened against the plate by means of screws in order to positively fix them in the designated position. Alternatively, rivets can be also be used that can be removed, as required, by means of simple tools, for example, by pressing them out. The reinforcing strips are designed and fixed to the metal sheets in such a manner that the reinforcement simultaneously serves to precisely position the plate (22) in order to positively prevent a vertical displacement of the plate during the operation of the heald shaft.

Description

technical field [0001] The invention relates to a heald frame, in particular for a weaving machine. Background technique [0002] To form the shed, the loom has a heald frame to which a plurality of healds are fastened, which guide the warp threads. Such a heald frame is known, for example, from DE 196 07 532 A1. The heald frame has an upper and a lower heald frame plate oriented transversely to the direction of motion of the heald frame, wherein the two heald frame plates fixed at a distance from each other and parallel are connected at their ends by so-called lateral supports. . A substantially rectangular frame in front view is thus formed. In this frame, a heald screw rod is respectively fixed on the upper heald frame plate and on the lower heald frame plate. Healds are fixed between the heald rods, and the healds are respectively hung on the heald rods with their heald lugs. Each heddle has a guide eye or eyelet for one warp thread. [0003] The heald rod is provi...
