Claim 5:
6. A method of deforming preforms using a registered shaping machine, comprising:
carrying the preforms in series on a conveyor;
reciprocating a tool table along an axis towards and away from the conveyor to bring forming tools at a plurality of tool stations on the tool table into and out of operative engagement with the preforms which are conveyed between the tool stations by indexed motion of the conveyor;
deforming the preforms to an out-of-round shape using a registered shaping tool located at one of the tool stations;
sensing the angular orientation of each preform in a plane normal to an axis of the preform using at least one sensor;
rotating each preform and the registered shaping tool relative to one another using at least one reorientation actuator, whereby the registered shaping tool and the preforms are brought into a predetermined relative angular orientation about an axis of the preform at the registered shaping tool station;
the relative rotation with respect to a given preform taking place during a plurality of reciprocations of the tool table and/or indexing movements of the conveyor.
