Abstract
Abstract A work support has a surface provided with at least one groove. A limit stop device is provided for positioning and retaining workpieces on this surface against displacement. The device has a pair of self-locking wedge-members which can be inserted into the groove with at least one of the wedge members projecting out of the groove and beyond the surface so that a workpiece can abut against it. The wedge members are displaceable relative to each other in the groove between a released and a self-locking position, and in the latter they are wedged against the walls bounding the groove and thus become immovable.
