Abstract
A new shaft drive provides for a switch-on and switch-off of individual heald shafts even at high working speeds. For this purpose switching pawls are provided which couple an eccentric with permanently revolving and/or back-and-forth oscillating disks. Measures for improving the controllability of such a clutch device are the control of the switching pawls by slot guides, associating bi-stabile biasing devices with the switching pawls and/or dividing the switching function into individual switching pawls () which are associated individually with differently running disks (). Preferably, one of the two disks executes a continuous rotary motion, while the respective other disk performs only an oscillating motion which determines the heald shaft motion during the resting phases thereof.
