Kupplungsvorrichtung für Textilmaschine, insbesondere spindellose Feinspinnmaschine

A clutch, particularly for use in spinning machines, has an outer drive part mounted for rotation on the hollow shaft of an inner driven part. The shaft supports a set of angularly spaced radial holders supporting groups of coupling pawls for angular movement to and from a coupling position engaging an annular inner gear of the drive part for coupling the drive part with the driven part. An actuating rod in the interior of the hollow shaft, moves all coupling pawls out of the coupling position into which the coupling pawls are urged by springs. Preferably, a group of thin coupling pawls cooperates with each tooth of the annular inner gear of the drive part so that the clutch engages after a relative displacement between the drive part and the driven part not greater than the thickness of a pawl.
