ABSTRACT:
A pressure sleeve for holding a container body blank in a die cavity at a redraw station in a press has a pair of notches formed in opposed side walls thereof. The notches provide clearance for a pair of opposed grippers of a transfer mechanism which moves container body blanks and formed container bodies between work stations of the press. The notches provide reduced travel distance of the transfer grippers thereby increasing press output speed.
