Embodiment Construction

[0029] figure 1 A heald frame 1 is shown, which has an upper heald frame bar 2 , a lower heald frame bar 3 and two side supports 4 , 5 . On the heald frame bar 2,3 fixed heald guide rail bar 6,7, they are as by figure 2 As can be seen, it can be made from flat profiled steel.

[0030] Usually, the heald frame rod 2 is made of figure 2 Visible, made from an aluminum continuous extrusion profile designed as a box-shaped hollow section. It has two side walls 8, 9 forming a flat surface. Bands 11 , 12 are provided at the top and bottom, which are integral with the side walls 8 , 9 and enclose an interior space 13 . The cross section of the heald rod 2 is constant over its length.

[0031] image 3 A variant of such a conventional heald rod is shown, which is designed as a double-chamber section with a longitudinally extending intermediate strip 10 . The heald rod has two inner chambers 13 , 14 . A part of the heald rod can be milled, in particular at its upper corner, in...

Abstract

The present invention provides a shaft rod 2 ) according to the invention has, particularly in its mid region, a particularly low mass. The shaft rod has an upper ledge ( 11 ) and a lower ledge ( 12 ) which have a reduced thickness in the mid region of the shaft rod. As a result, the load induced by acceleration forces is significantly less in the mid region than in conventional constructions. Byvirtue of the reduced acceleration forces, the extent of bending of the shaft rods in the middle is less and therefore a shaft rod of such a structure is better adapted for use in very rapidly operating weaving machines.

Description

technical field [0001] The invention relates to a heald frame rod for a heald frame and to a weaving machine equipped with such a heald frame. Background technique [0002] In order to form the shed, heald frames are used in looms, which carry healds and with which the warp threads are moved out of their central warp thread plane. Here the heald frames extend over the entire width of the fabric to be processed, each having a heald frame rod above the warp threads and below the warp threads. The ends of the heald rods are connected to each other by side supports. A heald guide rail rod with a heald is arranged on the heald frame rod. The shed is formed by a rapid upward and downward movement of the heald frame. After this upward and downward movement is induced by the rotational speed of the main drive shaft of the loom, an increase in the rotational speed of the loom is also mentioned in view of the faster and faster reciprocating speed of the heald frames. Efforts are b...
