After-sizer for polygonal spectacle frame edges - has clamp jaws and stroke hammers adjustable and pivotable at bending zones

摘要

The after-sizer for polygonal eyepiece edges for spectacle frames of profile wire has clamp jaws to push on the edge, with stroke hammers adjustably and pivotably fitted at the polygon zones (bending zones of the edge), so that their hammer heads respectively are movable over the zones. Preferably there are four jaws, interchangeable corresponding to the respective polygonal shape and movable centrally, together with a support edge for the respective eyepiece edge. The hammers are mounted by a superposed rotary frame to pivot concentrically of the jaws and in the working position in a plane with these, and can be raised for insertion of the eyepiece edges. Manual after processing is eliminated.
