The accumulator of an extrusion blow molding machine is constructed to include a stroke positioner that comprises inter-engaging, threaded components that enable the piston of the programming cylinder to be adjusted relative to the inner rod of the programming system in the accumulator assembly. Since the inner rod ultimately connects to the die pin, this adjustment directly determines the position at which the piston in the programming cylinder will close off the die gap. In particular, the components of the programming system can be adjusted so that the die gap is closed just as the piston of the programming cylinder reaches the limit of its stroke.
