Abstract

336,803. Vereinigte Leichtmetallwerke Ges., and Schwichtenberg, C. Oct. 21, 1929. Rivets; cased forms.-A rivet plated on the head or on the head and end of the stem is formed from a blank punched from metal sheet plated on one or both sides, the blank being pressed by dies a Fig. 3, to form a shouldered head b and stem and finished by a heading tool c and shank finishing punch d, Fig. 4, or the stem of the rivet may be formed by squirting, Fig. 6, in a die e, the stamp h forming the plated head and a punch forming the plating metal m into a sleeve on the end of the stem. Fig. 8 shows similar squirting apparatus wherein the stamp n coacts with a shear plate r in the die p to punch the blank from the plated sheet o.
