A device for gripping a hollow body includes a freely-rotating shaft and a mandrel that is integral with the shaft. The mandrel itself includes: an end fitting; a radiator that is mounted directly on the end fitting; a crosspiece inserted between the end fitting and the radiator; an expandable ring mounted between the end fitting and the crosspiece; an elastic element mounted between the end fitting and the expandable ring; an insert made of a material with high thermal conductivity, set in a housing made in the end fitting and emptying onto a free end face of the former, with the insert extending up to the point facing the radiator.

The invention relates to a method for controlling confined preforms which are stopped in a heating station during a production interruption, the heating station comprising a device for conveying preforms comprising individual supports which move in a closed circuit and a heating cavity which is bordered by at least one row of transmitters of monochromatic electromagnetic radiation. The method includes a step of heating, by the transmitters of the heating cavity, the confined preforms referred to as “cold” preforms which have been stopped before being exposed to the electromagnetic radiation emitted by the transmitters.

Described herein is a preform heating device, in particular a heating device which uses monochromatic infrared radiation preferably generated by lasers. In particular, a heating device for preforms is configured so as to be positioned outside a preform and radiate an electromagnetic radiation in the infrared range, forming a radiation disk in such a device according to a radial symmetry with respect to the center of the preform axis.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A trouble recovering method of an aseptic filling machine and an aseptic filling machine which can resume operation at an early stage if a trouble occurs in any of portions during an operation of the aseptic filling machine are provided.

A door of a chamber in which the trouble occurred is opened while a pressure in the chamber other than the chamber in which the trouble occurred is kept positive, the trouble is removed and then, the door is closed, an inside of the chamber in which the trouble occurred is cleaned as necessary, the inside of the chamber is sterilized and then, the operation of the aseptic filling machine is resumed.

Provided is an apparatus for heating plastic preforms with a transport device which is suitable and intended for transporting the plastic preforms along a predetermined transport path, with at least one stationary arrange heating device which heats the plastic preforms transported along the transport path, wherein the heating device has at least one heating element which emits radiation which heats the plastic preforms and at least one focusing device which focuses the radiation emitted by the heating element onto predetermined regions of the plastic preforms to be heated, wherein a position of this focusing device is changeable.

This disclosure provides new methods to characterize and relate residual stress and orientation imparted to the injection molded polymeric preform with orientation and residual stress in the resulting blow molded bottle. The method developed allows one to define and map the coupled thermal stress histories of both processes to define applicable preferred mutual processing windows for both preform and bottle molding processes. Stretch blow-molding parameters are developed using the disclosed method.

A continuously rotating, non-symmetric preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetric preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.

In a method for manufacturing a resin container, in the adjusting the temperature of the preform, the preform is accommodated in a cavity mold, a refrigerant introduction member is inserted into the preform, the refrigerant introduction member including a first flow path and a second flow path which are different in introduction or discharge position of a refrigerant, the preform is cooled by bringing the preform into close contact with an inner wall of the cavity mold at a pressure of the refrigerant introduced from the refrigerant introduction member. When the preform is cooled, cooling is performed by switching between a first cooling blow for introducing the refrigerant from the first flow path and discharging the refrigerant from the second flow path and a second cooling blow for introducing the refrigerant from the second flow path and discharging the refrigerant from the first flow path.

The apparatus for manufacturing a resin container includes a heating unit configured to heat a preform using heaters and, a blow molding unit configured to blow-mold the preform that has been heated, accumulators that are connected to the blow molding unit and for storing a pressurized gas to be used for blow molding, and a connection pipe that connects the heating unit and the accumulators via an electrically driven valve, in which the electrically driven valve is closed when electric power is supplied, and is opened when electric power is not supplied to cause the gas in the accumulators to flow to the heating unit.
