Claims
- 1. The method of transporting a plurality of parisons supported on spaced supports while moving through an oven to a plurality of molds whose center-to-center spacing is different from the spacing of said parisons in moving through said oven which comprises:
- grasping a group of at least three parisons while said parisons are still moving through said oven,
- raising said group out of said oven,
- simultaneously moving said group vertically and laterally toward said plurality of molds,
- changing the intra-parison spacing between the center parison and its two adjoining neighbors during such vertical and lateral movement toward said molds to achieve a spacing required by said center-to-center mold spacing,
- clamping said parisons in said molds after said spacing has been changed, and
- releasing the gripping on said parisons after such clamping.
- 2. A method according to claim 1 which includes the step of:
- tensioning the parisons in said molds to stretch the same axially.
- 3. A method according to claim 2 which includes the step of:
