ABSTRACT:
Control for a dobby mechanism with a wedge coupling between a drive shaft and an eccentric for the dobby motion, whereby the wedge is couplable and uncouplable with a coupling member in two coupling positions which are diametrically opposite to each other. Each coupling member is connected with one radially moveably mounted switching rod, that the two switching rods being in connection with each other via two control levers (which control levers under spring action are pulled into their starting position) and a coupling rod. One of the two control levers via a balance lever cooperates both with a known needle mechanism and with a control axle, the latter being moved back and forth synchronously in the rhythm of the pressure guides for the needle mechanism, whereas the other control lever is mounted on a fixed pivot axle.
