Abstract
The invention relates to a rotary dobby having a wedge coupling between a drive shaft and an eccentric device for the harness motion, in which the wedge is displaceably supported in a radially extending recess in an eccentric disk arranged in a crank arm and can be coupled and uncoupled in accordance with a pattern in an axially extending groove of the drive shaft at two diametrically opposite coupling locations by a shift rod which is controllable in accordance with a pattern and engages by a coupling member into a groove of the wedge which is open in axial direction of the drive shaft. In order to assure a dependable coupling and uncoupling at high speeds of revolution, the wedge is locked against displacement in its coupled position by a spring-biased locking pawl on the eccentric disk and the locking pawl is displaceable by the coupling member of the shift rod into a position which permits the uncoupling of the wedge.
