| Zusammenfassung: | In a biaxial stretch blow molding apparatus (
10
) for wide-mouthed containers, preforms (
6
) that are in an inverted state are conveyed on a single plane by preform carriers (
40
) that go around a carrier circuit (
30
) in the form of a loop, are heated via a heating station (
60
), and are then transferred via a transfer station (
80
) to stretch blow molding mold assemblies (
72
) that go around a circular looped path (
71
). The molded wide-mouthed containers (
1
) are taken out of the stretch blow molding mold assemblies (
72
) along a conveying path on a same plane and collected by a collection station (
90
). Wide-mouthed containers can be formed continuously and at high speed, which is less wasteful and more economical than the case where wide-mouthed containers that are formed from films. |
