Abstract
Machine for injecting and blowing a plastics material into hollow bodies. It comprises a rotary polygonal-sided turret which carries on each side a set of support members for the plastics material which are made to pass step-by-step to an injection station for injection of a blank and a blowing station for blowing the material into a hollow body in passing through intermediate stations including a transfer station. A rotatable oven structure having sockets rotatable step-by-step about an axis of the oven structure is located adjacent the transfer station for transferring the sets from the turret to the oven structure and, after a complete rotation about the oven structure axis, transferring the sets from the oven structure to the turret. Each turret side and each socket of the oven structure receives a respective one of the sets which is fixed to the turret or oven structure in a removable manner to allow the mentioned transfer. Heating means in the oven structure heat the material supported by the support members, during the rotation of the sockets, for the purpose of subsequently completing a bi-axial drawing of the plastics material at the blowing station.
