Abrégé

The invention relates to a shedding device (1), more particularly a Jacquard machine, and a shedding method for a weaving machine (2), wherein the shedding device (1) has a plurality of hook carriers (11, 12) each for a plurality of hooks (9, 10), which hook carriers can be moved up and down, and the shedding device has a drive device (15) for the hook carriers (11, 12), which drive device has driven control elements (17, 18), which act on the end regions (13, 14) of the hook carriers (11, 12). The drive device (15) has control elements (17, 18) that are driven autonomously, and independently of the weaving machine (2) in respect of driving, and separately or jointly, which control elements can be controlled differently.

The invention relates to a coupling device (1) and to a coupling method for releasably connecting harness strings (2, 3). The coupling device (1) has bushing-like and bolt-like coupling elements (4, 5) which can be joined together, comprising a connection zone (6) and a releasable locking means (7) having locking elements (8, 9) and a bushing-like releasing means (12) which, in the coupling position, is accessible from outside, can be actuated manually, and is movably mounted on the bolt-like coupling element (5). A resiliently deflectable latch element (8) is arranged on the bushing-like coupling element (4), wherein during actuation the releasing means (12) acts on the locking element (8) to release and displace the locking element.

Abrégé

The invention relates to a device and a method for shedding with a warp thread (5), said device (1) having a lifter (7) that is connected to a resilient spring element (9) and to the warp thread (5) and having a controllable actuator (11). The spring element (9) is non-rotatably clamped at both ends in mountings (13, 15) and is compressed at one side and axially by the actuator (11), forcing said element to flex and the lifter (7) to be oscillated by alternating flexural deformations of the spring element (9).
