ABSTRACT:
There is disclosed a chuck assembly defining a longitudinal axis for internally holding a hollow substrate having an open first end and a second end including: (a) an alignment shoulder positioned along the longitudinal axis; (b) an end portion, positioned along the longitudinal axis, that is adapted to be inserted into the substrate through the open first end and comprised of a polymeric member, wherein the polymeric member has a changeable width including a smaller width to permit insertion of the polymeric member into the substrate and a larger width to contact the polymeric member with the substrate inner surface, and the polymeric member is moveable along the longitudinal axis; and (c) a width changing apparatus operatively coupled to the polymeric member, wherein the polymeric member, which is in contact with the substrate inner surface, pulls the substrate a distance along the longitudinal axis towards the alignment shoulder when the polymeric member moves towards the alignment shoulder.
