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: Apparatus for producing plastic containers has a heating device having a transport device for transporting the plastic preforms singly along a predefined transport path. The transport device has a plurality of holding devices for holding the plastic preforms, and at least one heating unit for heating the plastic preforms, wherein furthermore a rotating device is provided which rotates the plastic preforms held by the holding devices and is connected to a forming device, which transforms the plastic preforms transported by the heating device into plastic containers. The apparatus has an alignment device which enables alignment of the rotational position of the plastic preforms with respect to their longitudinal direction relative to the holding devices holding these plastic preforms and/or the apparatus has a rotational position alignment device arranged along the transport path which enables alignment of a rotational position of the holding devices with the plastic preforms arranged thereon.

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.

Abstract: Provided are a handle-orienting preform feeding mechanism and orienting preform feeding method for a bottle preform with a handle. Under the combined action of the axial rotation of a plastic bottle preform and a handle positioning structure on a preform feeding tray, the handle of the plastic bottle preform with an integrated handle (especially a PET plastic bottle preform with an integrated handle) is positioned so that the plastic bottle preform with an integrated handle enters a heating machine and a bottle blowing machine of the next process according to the predetermined orientation. Accordingly, the wrong orientation of the integrated handle of the plastic bottle preform is avoided so that a mechanical arm can grasp the plastic bottle preform correctly and place the plastic bottle preform at the correct position of a bottle blowing mold. Thus the plastic bottle preform can be blown successfully.

Abstract: Plastic preforms are transported during their heating along a predetermined transport path and rotated with respect to their longitudinal axis during transport along a first transport path section to achieve uniform heating of the plastic preforms in the circumferential direction. The plastic preforms remain at least in sections in a predetermined first rotational position with respect to their longitudinal axis during their transport along a second transport path section so that first predetermined circumferential sections of the plastic preforms are heated differently from second predetermined circumferential portions of the plastic preforms. The plastic preforms remain at least in sections in a predetermined second rotational position with respect to their longitudinal axis during their transport along the second transport path section, the first and the second rotational position differing from one another by a predetermined differential angle.

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 C 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.
