Abstract
A process for angular indexing of a pre-form having a body and a neck. The process includes a step of marking the neck of the pre-form which consists of production of at least one reference point on the neck of the pre-form. The process also includes a step of a heating station taking charge of the pre-form, during which the pre-form is transported along a heating course by a support unit, known as a spinner, which makes it possible to turn the pre-form around its axis, and during which the body of the pre-form is heated. The marking step is carried out during the step of taking charge, when the pre-form, supported by a spinner, travels along the heating course.
