Embodiment Construction

[0031] FIG. 1 shows a heald frame comprising an upper shaft 2 , a lower shaft 3 and transverse supports 4 , 5 . The shafts 2, 3 and the transverse supports 4, 5 are connected to each other to form a rectangular frame which in operation can be moved vertically up and down by a drive mechanism not specifically illustrated in the figures. The frame supports healds 6 for guiding the warp threads in the loom. Guides 7, for example composed of wood, are fixed to the shafts 2, 3 in order to maintain the distance between adjacent heald frames. Alternatively, the guide 7 can be replaced by other mechanisms.

[0032] Basically, the shafts 2 , 3 correspond to each other, so that the following description of the shaft 2 also applies to the shaft 3 .

[0033] The shaft 2 comprises a shaft body 8 substantially made of a sheet metal member 9 . The sheet metal member 9 is, for example, shown alone in FIG. 9 . It may be a component produced by a roll forming process. This member has a con...

Abstract

The shaft rod in accordance with the invention consists of only one (steel) metal sheet which is essentially configured without a large hollow chamber. The metal sheet has two stiffening means which are preferably located at the top and at the bottom of the shaft rod and are configured as edges. Preferably, the upper stiffening means ( 10 ) is implemented in the configuration of a small hollow chamber or of a solid reinforcement. The lower stiffening means ( 11 ) is implemented by attaching the heald support rail. Attachment may occur in accordance with any joining method, such as, for example, welding, cementing, clinching. The shaft rod may be manufactured by shape-rolling or roll-forming, as well as by all other reforming processes that are suitable for metal sheets. It is preferred that the heald support rail be directly integrated in the sheet metal form of the shaft rod. As a result, the entire shaft rod consists of a single metal sheet.

Description

technical field [0001] The present invention relates to shaft rods, in particular heald shafts for looms that do not run too fast. Background technique [0002] In order to provide a cost-effective weaving machine, it has been an aim to manufacture the shaft in a cost-effective manner. Currently, shafts typically include light metal cavity profiles to achieve greater stiffness at lower weight. The outlay and effort required to manufacture the shaft for this purpose is generally relatively high in most cases. [0003] For example, US Patent No. 4,633,916 discloses a shaft comprising metal profiles defining between these metal profiles cavities of rectangular cross-section, said cavities being filled with a honeycomb structure. In addition, a reinforcing profile is provided on one narrow side of this cavity, the parts being bonded to each other. [0004] In addition, the manufacture of roll-formed sheet metal components is also contemplated. In this regard, US Patent No. 4...
