Pedestal assembly
Abstract
Abstract A pedestal assembly for accurately receiving and positively capturing a lower thermoplastic container half when it is being transferred into and rotated by a spin welding apparatus. The spin welding apparatus frictinally joins the lower container halt to an upper container half to form a unitary container. The lower container half is received by the pedestal assembly from a rotating star wheel transfer device which slides the lower container half onto a stage portion of the assembly. The pedestal assembly having the container half thereon is then rotated in an opposite direction from that of the star wheel transfer device. The pedestal assembly including the stage portion has a dome-shaped upper surface which cooperates with a complementary recessed bottom of the lower container half. Vacuum means is applied through a central opening in the pedestal assembly for aiding in the positive capture of the lower container half.
