Abstract

509,983. Stamping. DEUTSCHE ROHRENWERKE AKT.-GES. Nov. 28, 1938, No. 34654. Convention date, Feb. 1. [Class 83 (iv)] A metal bottle 2 is necked-in between mandrel dies 5 and 7, the die 5 comprising radial segments pressed out to the required size by the descent of a tapered plug 4 and maintained under pressure between the stop 3 and the plug 4 while the matrix cylinder 6 descends. On withdrawal of the plug 4, spring pressed stops 8 move in horizontally to prevent the segments 5 rising with it and allow them to close up and be lifted out of the .bottle. The bottle is ejected by fluid pressure under the piston 9.
