Abstract

556,495. Spinning-machines. ROBBINS, H. G. May 19, 1942, No. 6753. [Class 83 (iv)] A sheet metal blank 5 or a spun or stamped article is spun or planished against a former 7 by a multiplicity of balls adapted for relative displacement. The blank 5 is held against the former 7 by a plate 4, these being carried by shafts 6, 3 respectively. The balls are held between a spring-pressed member 8 and a cup 1, rotated by means of a pulley 2 and moved up, to spin the blank, by means which may act through a spring 14. If desired, the cup 1 may be non-rotary and the former 7 and plate 4 be rotated.
