Abstract
A machine for manufacturing hollow bodies by blow molding thermoplastic preforms includes at least one preform heating apparatus and an assembly of molding stations fixedly arranged in an arc of a circle. The molding stations each further include a finished product ejector. A rotary transfer device is provided between the heating apparatus and the molding stations to transfer the heated preforms. The transfer device preferably has the shape of a wheel coaxial with an arc of a circle on which the molding stations are arranged. The wheel includes a carrier distributed uniformly along a circle to take heated preforms and deposit them into receptors on the molding stations.
