Abstract

557,998. Celluloid mandrels. MORRIS MOTORS, Ltd., DONO, G. E., and GODDARD, R. H. Jan. 2, 1942, No. 81. [Class 2 (ii)] [Also in Group XXII] In bending a thin metal tube a this is supported internally by a mandrel b of celluloid or other non-metallic material sufficiently elastic to return to its initial straight form when removed from the bent tube but not to effect the shape of the tube between successive passes between bending rollers.
