Abstract: A device for inverting hollow bodies gripped by the neck, characterized in that it includes a series of gripper mounted at the periphery of a rotary wheel and each of which is adapted to grip a hollow body by the neck, and each gripper is mounted on a wheel so as to be tilted between a first and a second position, and each gripper is designed to grip the neck of the hollow body at two substantially opposite points on either side of the neck axis, and the gripper is designed to cause the neck of the hollow body to be engaged in the gripper by one side of the gripper and to be released by the other side of the gripper, with substantially radial movements relative to the neck axis.

Abstract: A blow molding machine including at least a blow mold (12), wherein is introduced a preform (14) previously produced by injection molding, and a blow nozzle (22) for injecting pressurized air into the preform (14). It is equipped with a device for orienting the preform in the mold, the device including a grip member (30) adapted to grip the preform (14) by its neck (18) when it is engaged in the mold (12); a device (66) for driving in rotation the grip member (30); a device for detecting (70) at least a reference angular position of the preform (14); and a control device to cause the grip member to rotate until the detecting device detects the reference angular position of the preform.

Abstract: The invention concerns a blow moulding machine comprising at least a blow mould (12), wherein is introduced a preform (14) previously produced by injection moulding, and a blow nozzle (22) for injecting pressurised air into the preform (14). The invention is characterised in that it is equipped with a device for orienting the preform in the mould, said device comprising a grip member (30) adapted to grip the preform (14) by its neck (18) when it is engaged in the mould (12); a device (66) for driving in rotation the grip member (30); a device for detecting (70) at least a reference angular position of the preform (14); and control means to cause the grip member to rotate until the detecting device detects the reference angular position of the preform.
