Abstract
A method of measuring the wall temperature of a container blank, including the following operations: inserting a temperature probe into the blank in motion, upon completion of the operation of heating the blank in an oven; maintaining the probe in the blank in motion for a predetermined time; making a temperature measurement by the probe maintained in the blank without contact with the inner wall of the blank; and storing the temperature or the temperature profile thus measured.
Claims19
A method of measuring the wall temperature of a container blank, comprising:
- Inserting a temperature probe into the blank in motion, upon completion of the operation of heating the blank in an oven;
- Maintaining the probe in the blank in motion for a predetermined time;
- Making a temperature measurement by means of the probe maintained in the blank without contact with the inner wall of the blank;
- Storing the temperature or the temperature profile thus measured.
A device for measuring the inner wall temperature of a container blank, comprising a contactless temperature measuring unit, movably mounted along a circuit comprising a working section coinciding locally with a path of the blank and a buffer section separated from said path, said measuring unit being movably mounted between a standby position, adopted in the buffer section of the circuit away from the blank, and a measuring position, adopted in the working section of the circuit and in which the measuring unit is at least partially inserted into the blank in order to take a temperature measurement there without contact with an inner wall of the blank.
A method of measuring the wall temperature of a container blank, comprising:
- inserting a temperature probe into the blank;
- maintaining the temperature probe in the blank while the blank is conveyed along a conveying path;
- taking a temperature measurement with the temperature probe while the temperature probe is maintained in the blank while the blank is conveyed.
