Abstract
A dobby mechanism with a coupling, controlled according to a design, between a stationary drive shaft and a first gear with the number of teeth n, which first gear meshes with a second gear with the number of teeth 2n on a stationary axle, on which second gear an eccentric device for the dobby movement is arranged, whereby the drive shaft and the first gear are coupleable with each other by means of a radially movably mounted wedge, which wedge is controlled with a switching member from the outside according to a design, and in the coupled condition partially engages in a radially extending recess of the first gear and partially in an axially extending groove of the drive shaft. In the uncoupled condition the wedge is completely uncoupled from the drive shaft and the switching member comprises a switching rod, the latter being controlled according to the design, the switching rod in the coupling range engaging with a coupling member in a groove of the wedge.
