Stretchable fabric
First warp yarns and second warp yarns are each interwoven with weft yarns to produce a one-layer, lightweight, stretchable fabric. The first warp yarns include stretchable yarns that are activatable to achieve a contracted state, and the second warp yarns include non-stretchable yarns. The first warp yarns may include a stretchable core yarn with non-stretchable wrap yarn wrapped around the stretchable core yarn. The first warp yarns may be in an alternating arrangement with the second warp yarns. When the yarns are woven together, the first warp yarns are in an extended state and the second warp yarns are in an unbunched state. The fabric then undergoes a finishing procedure during which the first warp yarns are activated to achieve a contracted state. The second warp yarns thus achieve a bunched state, and the resulting fabric is stretchable in the warp direction.

A novel rod linkage for driving a heddle shaft includes at least one strap (16), which for damping oscillation has a sandwich structure (37) oriented in the longitudinal direction (L) of the strap assembly (16). The sandwich structure includes at least one rigid element (27), extending in the longitudinal direction, which is joined to one end (17) of the strap assembly (16); a second rigid element (31), likewise extending essentially in the longitudinal direction, which is joined to the other end (19); and a two-dimensional damping element (34), again extending in the longitudinal direction, disposed between the first two. The element (34) exclusively effects the mechanical connection of the two parts (16a, 16b) of the strap assembly (16). Preferably, no additional connecting elements, such as rivets, screws, or other rigid connections, between the rigid elements (27, 31) are provided. Preferably, the rigid elements (27, 31) are embodied as wedges pointing in opposite directions, which thus define a wave resistance that varies in opposite directions in the longitudinal direction. This wave resistance brings about an intentional coupling misadaptation with respect to the oscillation transmission. The element (34) disposed between them damps the oscillations additionally, so that the strap assembly (16) transmits driving motions like a filter and destroys or absorbs interfering oscillations.

Weaving Machine and Method for Three-Dimensional Weaving
a weaving machine and a weaving method for direct three-dimensional weaving, wherein the weft thread (32) is imparted with its desired two-dimensional course already when the weft thread is being input. The position of the warp threads (12) is adapted to the weft thread path (23). The weft thread path (23) is defined by the lamellae (44) that extend into the shed (21) in between the warp threads (12). The lamellae (44) are arranged on a common bar (45) so that they can be individually adjusted, thus enabling the adjustment of the desired weft thread path (23) by positioning the lamellae (44). The lamellae (44) and the bar (45), at the same time, form the reed (43) that is used for casting on the weft thread (32) at the fabric edge (16).

The shed of a fluidic weaving loom is not changed simultaneously for all warp threads, but rather continuously starting at the weft entrance and continuing helically, so to speak, to the exit of the warp shed. This sequential shed closure takes place with a so-called domino effect along a helical line curved in space, whereby additional time is gained for stretching the inserted weft thread and temporarily stopping the shed formation or shedding is avoided.
