Abstract

Method for heating a preform () comprising: introducing the preform () into a heating apparatus () comprising an array of infrared emitters () arranged in multiple columns (Cj) and multiple rows (Ri), orienting angularly the preform at an input angular position by rotating the preform around the longitudinal axis; setting power levels of the infrared emitters () so as to divide the array of infrared emitters () into subsets of columns (SCn), each subset of columns (SCn) generating heat at a different power level from an adjacent subset of columns (SCn); and heating the preform () with the array of infrared emitters () while translating the preform () in a direction parallel to the rows (Ri) of the array at a translation speed, and simultaneously rotating said preform () around its longitudinal axis (A) in front of said infrared emitters () at a rotation speed.
