Embodiment Construction

[0017] A rapier conveyor 10, shown in FIG. The shed 13 is formed by lifting warp threads 14 , 15 . Once the rapier conveyor 10 has received the weft thread, the weft thread is separated by the fabric 16 . After the weft yarn 11 is sent into the shed 13, it is beaten on the edge of the fabric 16. Typically, the rapier conveyor 10 feeds the weft yarn all the way approximately to the center of the shed 13 . There, the weft thread 11 is picked up by a rapier receiver (not shown in the figure) and brought to the opposite side. The rapier conveyor 10 is fastened to a rapier belt 17 which is pushed together with the rapier conveyor 10 into the shed 13 by means of a drive (not shown) and pulled out of the shed.

[0018] The rapier conveyor 10 comprises a base body which is made of a thin sheet, in particular sheet steel, which is bent into an approximately tubular shell. The rapier conveyor 10 essentially has a U-shaped cross section. The crossbar 18 is located on the top face of...

Abstract

The invention relates to a rapier housing, especially for a transfer rapier of a loom. The rapier housing is composed of a metal plate whose edges form guides (23, 25, 26, 31) having a width that is larger than the thickness of the metal plate.

Description

technical field [0001] The invention relates to a rapier case for a rapier of a weaving machine, in particular a rapier case for a rapier conveyor, made of one or more metal plates, the edges of which at least partially form the guides for the yarns device. Background technique [0002] In order to achieve high-speed weaving, the rapier should be as light as possible. A reduction in rapier dimensions was provided for this. But this reduction is limited because certain minimum dimensions must be maintained. [0003] In rapiers of this type, as in the rapier described in WO 99 / 18274, a base body made of one or more thin sheets, in particular thin steel sheets, is bent. In order to achieve further weight savings, efforts are made to reduce the thickness or wall thickness of the above-mentioned metal plates or sheets. Although the thickness may be 0.3 mm to 0.5 mm for strength reasons, this is practically impossible. The edges of this thin metal plate act like blades or bla...
