<p>A coupling device (100) has a controllable clutch for selectively coupling the mechanical elements (10,20) to a drive element (53). The coupling device has a freewheel which is set up such that the mechanical elements are moved from one end position to other end position, during half cycle movement of the drive element, by interaction with the freewheel. A feedback element (70) set to work synchronously with the drive element is moved such that the mechanical elements are moved from one end position to other end position during half cycle movement. An independent claim is included for method of generating controlled reciprocating movement of movable mechanical elements between two end positions.</p> |
