Abstract
A normal position of a shifting wedge of a lifting unit for a rotational dobby is achieved by a movable arrangement of the recess in a locking block which receives the wedge and has rigid side flanks. The entire locking block is, against the urging of a spring, supported for movement translatorically and/or swingably within certain limits, wherein the center axis of the recess moves only insignificantly out of its normal radial orientation.
