Abstract
Provided is a method for heating a succession of preforms. The method includes heating a body of a first preform using two heating elements that each heat a heated area of the body. The method includes determining a target heating temperature for each heated area according to the container to be produced, measuring the temperature of one of the heated areas of the body upon completion of the heating step, and modifying the heating power of the heating element corresponding to the heated area of the body if the measured temperature of the heated area is different from the target heating temperature. The method further includes heating the body of the other preforms of the succession of preforms with the modified heating power.
Claims11
A method for heating of a succession of preforms for the production of containers by deformation of the said heated preforms, each preform comprising a body extending along a preform axis, the method comprising the following steps:
- heating the body of a first preform of the succession of preforms with at least two heating elements, with each heating element heating a different heated area of the body of the first preform along the preform axis;
- determining at least one target heating temperature for each heated area of the body of each preform, according to the container to be produced by deformation of each heated area of the preform;
- measuring the temperature of at least one of the heated areas of the body of the first preform upon completion of the heating step;
- modifying a heating power of the heating element corresponding to the said heated area of the body if the temperature measured of the said heated area is different from the target heating temperature, the heating power being modified in order for the temperature of the corresponding heated area of the preform to be substantially equal to the target heating temperature;
- and
- heating the body of the other preforms of the succession of preforms with the modified heating power.
