A blow molding apparatus includes: an injection molding section for injection molding a plurality of preforms at a time; a cooling section for cooling the preforms; a heating section for heating the preforms while continuously transporting them along a transport line; and a blow molding section for blow molding the preforms to form hollow containers. The blow molding section includes a primary blow molding section which is equipped with a heat-treating blow mold and blow molds the preforms moved from the transport line into the heat-treating blow mold to form intermediate molded products, and a secondary blow molding section which is equipped with a final blow mold and blow molds the intermediate molded products moved from the heat-treating blow mold into the final blow mold to form the hollow containers.

An apparatus for molding a handle-equipped container is provided. The apparatus has a gripping mechanism section 160a which comprises a first gripping member 161 having a pair of first chuck members 163 for grasping a preform 200, and a second gripping member 162 having a pair of second chuck members 167 for grasping a container handle 20 in association with the action of the first gripping member 161. The apparatus can simultaneously grasp a plurality of the preforms 200 and a plurality of the container handles 20 and reliably transport them to a blow molding section.

A synchronous running safeguard for transfer stations or devices for handling containers, in particular for handling bottle-like containers made of glass or plastic, having a first and a second rotary element, which each have holding elements for the containers and each have a motor drive. The rotary elements are disposed in relation to one another such that the containers can be transferred in a transfer area from one of the first holding elements to one of the second holding elements. The rotary elements, each rotationally connected, have a control element having engagement elements, and the control elements are in meshing engagement with one another. The control elements are disposed in such a way that, during operation the control elements are interengaged without contact during the rotary movement of the rotary elements and that, in the event of a fault, the control elements are interengaged with contact.

An apparatus for handling plastic preforms includes a feeding line for preforms that comprise a preform body and a preform mouth, a conditioning oven, a setdown device for the preforms being provided which is designed to feed the preforms to a transfer or blow-molding carousel, the conditioning oven being associated with a closed conveyance circuit which includes supporting elements to support respective preforms. The feeding line has a feeding device to feed the preforms to respective supporting elements; the setdown device has an overturning element adapted to pick up the preforms and to bring them to a pickup condition in which the respective mouths are directed upward. The setdown device further includes a pickup device to pick up the preforms in the pickup condition from the overturning element to feed them to the transfer or blow molding carousel.

A blow molding device and a blow molding method are disclosed that can blow-mold a container with a handle without requiring a handle inserter that inserts a handle into a blow molding section. A blow molding method for blow-molding a container with a handle includes heating a preform (2) that is held by a heating transfer jig (370), transferring the preform from the heating transfer jig to a blow transfer jig (420), and transferring the blow transfer jig in a state in which a handle (500) is held by the blow transfer jig to be adjacent to the preform in a transfer direction.
