Abstract
384,944. Making platens for rolling screw-threads. FULD, H., 71, Frauentorgraben, and HESSDÍRFER, E., 10, Tiergartenstrasse, both in Nuremberg, Germany. July 25, 1932, No. 20953. Convention date, July 24, 1931. [Classes 83 (ii) and 83 (iv).] Platens R, R<1> for rolling non-intersecting but parallel screw-threads are made from platen blanks by rolling between them a hardened threaded die bolt r. The platens are bevelled at their ends n. Both platens may move in opposite directions or one may be stationary. The top platen is screwed down by bolts d as required after each pass. The grooves may be rolled to final form by preliminary intermediate and finishing threaded die bolts r. Both platens are adjustable sidewise.
