Method of indexing a preform comprising lugs during the production of a container and station and device used for same

摘要

A method of indexing a preform (1) includes anchoring lugs (2) which project out from the body of the preform, the method being used when a container, such as bottle, is being produced from the preform by blowing or blowing/drawing. The method includes a heating step which is performed prior to the blowing or blowing/drawing step, whereby the preform is disposed on a transport support such that it can be rotated around the longitudinal axis thereof. Following the heating step, the preform is transferred to a corresponding mould (300) by a transfer clamp (210). The indexing step consists in mechanically blocking the rotation of the preform on the transport support thereof at a precise angular position which is determined according to the desired position of the preform in the mould (300).
