<p>The clamp consists of a flat support for the top of a plastic bottle preform neck (3), a curved thrust member (2) for the outer surface of the neck and a pivoted pin (4) that is held against the neck's inner surface by a spring-loaded lever (7). A roller (6) on top of the lever interacts with an actuating mechanism to open the clamp and release the preform at an appropriate point.</p> |
