摘要

Clamping device for the opening out and holding of, in particular, cut-open unround piston rings, preferably in batches, for machining the said rings in the region of the gap, by opening out the work pieces by means of a spreading element, such as preferably a bar of triangular cross-sectional profile, and clamping them in the opened-out state between clamping jaws bearing on both sides against the associated circumferential surfaces of the piston ring gap, and subsequently machining them. <IMAGE>
