Abstract

870,861. Making washers. WERTHEIMER, R. Dec. 4, 1957, No. 37740/57. Class 83 (2). [Also in Group XXV] A washer (see Group XXV) in the form of a strain-hardened cup 1 with a profiled rim 5 is made by deep drawing cold from a sheet metal blank and squashing the cup to form the profiled rim. A compound die simultaneously performs the squashing operation and cuts a hole 2 centrally in the flat end 1.
