Embodiment Construction

[0031] figure 1A heald frame 10 is shown, which is a part of a loom which is not particularly shown. The heald frame represents a rectangular frame in which the individual heddles 11 are arranged. Healds are provided for guiding warp threads, not shown in particular, during the weaving process. The heald 11 is arranged on the heald support rails 12 and 13, and the heald support rails 12 and 13 are horizontally arranged with a certain vertical distance therebetween. The upper heald support rail 12 is held on the upper heald frame rod 14 . The lower heald support rail 13 is held on the lower heald frame rod 15 . Each of the upper and lower heald shaft rods 14, 15 is constructed of a suitable lightweight material, such as fiber reinforced plastic, honeycomb reinforced sheet metal, thin wall extruded aluminum profiles or the like. Lateral supports 16 , 17 are connected to the ends of the heald frame rods 14 , 15 so as to form a rectangular frame with the heald frame rods 14 , ...

Abstract

The invention provides a heald shaft with a lightweight shaft rod. The heald shaft comprises at least one haft rod and at least one side supporting member made of light materials, and the haft rod and the side supporting member are connected with each other via a specially constructed accepting part. The accepting part comprises two perferably flat members, and at least one flat member is connected with two butting elements. One of the butting element is retained or installed fixedly, and the other one is retained or installed to be able to move slightly. The two butting elements are protruded out of the edges of the right sides of the flat members at different distances, a tensioning component plays a part between the two butting elements and is configured to tension the shorter butting element toward the longer butting element, so that an extending part of the side supporting member is clamped at an appropriate position between the butting elements. The flat members transmit force between the side supporting member and the shaft rod, and the force is applied on a large surface of the shaft rod.

Description

technical field [0001] The invention relates to a heald shaft with a shaft rod made of fiber-reinforced plastic material. The invention relates in particular to the connection between the lateral supports of the heald frame and the heald frame rod. Background technique [0002] In general, heald shafts are rectangular frame-shaped structures comprising horizontally arranged long shaft shafts and vertical lateral supports connecting the shaft shafts to each other along their respective ends. The heald frame rod supports a heald support rail for receiving the healds. The basic structure of such a heald frame can be derived, for example, from the publications DE 10116813B4 or EP 0531886A1, EP 0695178B2 or EP 1985733A1. In order to install the healds on the heald support rail, the heald frame needs to be detachable. To do this, connect the lateral supports to the heald frame rods using suitable corner connectors. In most cases, corner connectors are designed as clamping or t...
