Abstract: A stretch blow moulding system for PET containers with PET integral handles; the containers blown from injection moulded preforms; each preform having the integral handle projecting from a junction point on a body portion of the preform; containers blown in a continuously rotating stretch blow moulding machine of the system. In a preferred form the preforms are progressed continuously at a substantially constant speed; the containers blown therefrom progress at the same substantially constant speed through to the filling and capping machine; and wherein the containers progress continuously through the filling and capping machine at the same substantially constant speed. Also described is a continuous stretch blow moulding system applied to specified integral handle PET preform and PET blown container structures stretch blown from the preforms thereby to obtain variable wall thickness of the preforms and/or variable wall thickness of the containers.

Abstract: A method for heating a preform (1) comprising a body portion (4) 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 (1) into a heating apparatus (5) comprising an array of infrared emitters (50) arranged in multiple columns (Cj) and multiple rows (Ri); - setting power levels of the infrared emitters (50) so as to divide the array of infrared emitters into subsets of columns (SCn); and - heating the preform while translating it in a direction parallel to the rows (Ri), and simultaneously rotating said preform (1) around its longitudinal axis, the rotation and translation speeds, and the power levels of the infrared emitters (50) being set so that the greater the thickness of the zones of the body portion (4), the higher is the power level of the subsets of columns (SCn) facing said zones.
