Abstract
The arrangement contains a carrier (4) which is mounted in a drive shaft (1) which is formed as a hollow shaft with holes (10) which are arranged in a radial plane, two switching tappets (5) which are displaceably arranged in the holes, two control members (7) which can be brought into operative engagement with the switching tappets, means (8) for the actuation of the control members and two resetting elements (9) for the control members (7). The control members are displaceable in the carrier with respect to the drive shaft into a first position in order to switch the coupling apparatus into a drive position and into a second position in order to switch the coupling apparatus into an idling position. The resetting members (9) are arranged inside the drive shaft (1) in order to displace the control members (7) into the second position. With this arrangement the resetting of the control members is ensured. In a coupling apparatus for a rotational dobby with an apparatus of this kind two followers are provided for the coupling of the drive shaft with the eccentric disc which can be brought into and out of engagement at the same time in order to divide up the holding force acting on the follower.
