Claim Text:
1. Installation ( 1 ) for producing hollow bodies ( 2 ) by injection molding and subsequent blow molding, comprising an injection molding tool ( 4 ) with a tool part ( 19 ), at least one cavity ( 5 ) for producing a preform ( 3 ) with a neck continuation ( 18 ) and a hollow body part ( 22 ) adjoining the neck continuation ( 18 ), a blow mold ( 6 ) for shaping the hollow body ( 2 ) from the preform ( 3 ) and transfer means ( 7 ) for transporting the preform ( 3 ) from the injection molding tool ( 4 ) to the blow mold ( 6 ), wherein the transfer means ( 7 ) comprises a carrying frame ( 9 ) on which at least one holding element ( 10 ) for the at least one preform ( 3 ) is disposed and when the preform ( 3 ) is being transferred between the opened injection molding tool ( 4 ) and the transfer means ( 7 ), the preform ( 3 ) is held by the outside of its neck continuation ( 18 ) by the tool part ( 19 ) of the injection molding tool ( 4 ) and is removed from the cavity ( 5 ), wherein the carrying frame ( 9 ) is guided by a guide arrangement formed by transport rails ( 8 ), in a straight transport movement between the injection molding tool ( 4 ) and the blow mold ( 6 ) , the transport rails ( 8 ) defining a horizontally oriented transport plane ( 41 ), wherein when the preform is being transferred between the opened injection molding tool ( 4 ) and the transfer means ( 7 ), the direction of movement of the preform ( 3 ) is vertical and perpendicular to the transport plane ( 41 ), and the preform ( 3 ) is placed onto the at least one holding element ( 10 ) by the inside of its neck continuation ( 18 ) and the at least one holding element ( 10 ) thus lies in contact with an internal face ( 20 ) of the neck continuation ( 18 ), and wherein the at least one holding element ( 10 ) has at least one gap in the region of its center forming an orifice ( 69 ) for supplying blowing air ( 68 ) as well as a stretching tool into an interior of the preform ( 3 ), and the neck continuation ( 18 ) is held by the at least one holding element ( 10 ) during the blowing operation to form the hollow body ( 2 ).
