Abstract

A method for heating a preform () comprising a body portion () having a thickness which varies progressively along any transverse cross-section between a thick zone and a thin zone of the body portion. The method comprises the following steps: —introducing the preform () into a heating apparatus () comprising an array of infrared emitters () arranged in multiple columns (Cj) and multiple rows (Ri); —setting power levels of the infrared emitters () so as to divide the array of infrared emitters into subsets C of columns (SCn); and—heating the preform while translating it in a direction parallel to the rows (Ri), and simultaneously rotating said preform () around its longitudinal axis, the rotation and translation speeds, and the power levels of the infrared emitters () being set so that the greater the thickness of the zones of the body portion (), the higher is the power level of the subsets of columns (SCn) facing said zones.
