Abstract
A method for orienting a preform of axis in a forming mold of a blowing machine, a neck of the preform being provided with at least one marker, the method including (i) installing the preform in the mold; (ii) detecting the current angular position of the preform by determining the angle of rotation through which the preform has to be rotated to reach the reference angular position thereof; and (iii) orienting the preform about the axis thereof in relation to the mold until a reference angular position is reached.
Claims19
A method for orienting an axisymmetric preform of a main axis in a forming mold of a blowing machine, a neck of the preform being provided with at least one marker enabling determination of the angular position of the preform about the main axis thereof in relation to a reference angular position that is static in relation to the mold, the method including:
- installing the preform in a cavity of the mold, the neck projecting outside the mold,
- detecting the current angular position of the preform and calculating an angle of rotation through which the preform has to be rotated to reach the reference angular position thereof, wherein calculating the angle of rotation includes determination of a minimum angle and of a related direction of rotation in which the preform has to be rotated to reach the reference angular position thereof, and
- orienting the preform thus installed, in which the preform is automatically rotated about the axis thereof in relation to the mold until the reference angular position is reached, wherein the orienting is triggered on completion of the detecting.
