Abstract: In an injection stretch blow molding method, at least one injection molded preform is transferred from a preform molding section to a blow molding section by way of a transfer section and the at least one preform is blow molded into at least one container in the blow molding section. In the preform molding section the at least one preform is injection molded in an upright state with an open neck section thereof facing upward. In the transfer section, the at least one upright preform is turned upside-down and transferred to the blow molding section in an inverted state. Then, the blow molding section blow molds at least one container from the at least one inverted preform.

Abstract: An injection stretch blow molding apparatus has an injection molding station and a blow molding station, with a transfer station positioned therebetween. The injection molding station has an injection molding section which molds preforms and a removal section which removes the preforms from an injection core mold. The blow molding station carries out circulating transfer of carrying members which support the preforms, and in the blow molding section the preforms are blow molded into containers. The transfer station has a receiving mechanism which receives preforms removed from the injection core mold in the injection molding station in the upright state, an inverting receiving mechanism which inverts the preforms and passes them in the inverted state to carrying members, and between the receiving mechanism and the inverting receiving mechanism, a movement mechanism transferring the preforms from the receiving mechanism to the inverting receiving mechanism.

Abstract: A preform heating device has a plurality of infrared heaters disposed horizontally and spaced apart in the axial direction of a preform carried along a carrying path which carries a preform in a state that the axial direction thereof is vertical. The preform is at least rotated when facing the infrared heaters. First and second insulating plates, and an insulating air layer formed therebetween are disposed facing the carrying path with the infrared heaters between. The infrared heaters are supported by a plurality of support members. Each of this plurality of support members is able to be moved upward and downward by a height adjustment means, and is fixed to the second insulating plate at a given vertical position.

Abstract: An injection stretch blow molding apparatus has a preform molding section for molding preforms and a blow molding section for blow molding containers from the preforms retaining heat from when the preforms were injection molded. At a location in a path along which the preforms are carried from the preform molding section to the blow molding section there is a discharge guide section for guiding preforms which are not to be carried to the blow molding section off the carrying path.

Abstract: An apparatus for molding a container has a standby section disposed between a heating section and a blow molding section. A preform is supported by carrier members, and is intermittently carried from the heating section via the standby section to the blow molding section. In the standby section are provided a temperature conditioning member which conditions temperature on the preform carried from the heating section; a positioning plate which positions a carrier member stopped at the standby section; and a cylinder which advances and withdraws the temperature conditioning member with respect to the preform, and simultaneously advances and withdraws the positioning plate with respect to the carrier member. The advanced positioning plate contacts with the carrier member to position the carrier member. The advanced temperature conditioning member is set enabling temperature conditioning of the preform.

Abstract: A blow molding apparatus which can be simplified in structure, reduced in size and facilitated in maintenance, and which can improve the heat efficiency and equalize the temperature gradations. The blow molding apparatus has a preform supply section, preform heating sections, a blow molding section, a product removing section and a conveying section. The conveying section intermittently conveys preforms while maintaining a fixed spacing between adjacent preforms. The preform heating section is divided into first and second heating portions. The first heating portion has heaters extending along the preforms while the second heating portion includes heaters extending in the direction of preform conveyance and aligned vertically. The first heating portion heats the preforms, and the second heating portion applies a temperature distribution to the preform.

Abstract: An injection stretch blow molding method sequentially circulates a plurality of neck mold moving units for supporting and conveying neck molds adapted to hold the neck portions of hollow containers and preforms used to mold the hollow containers at least through preform injection molding, blow molding and ejecting stations, the preform injection molding step, the blow molding step for blow molding the hollow containers from the preforms having their potential heat provided by the injection molding step and the product ejecting step being repeatedly carried out. The injection molding stations of M in number are provided for blow molding stations of N in number (M>N.gtoreq.1). Preforms are injection molded in each of the injection molding stations at an injection molding start time staggered from those of the other injection molding stations by time equal to N.times.T/M where T is an injection molding cycle time in each of the injection molding stations.
