Method and machine for the manufacturing of containers allowing a modification of a heating rate

摘要

The method involves modifying the speed of movement of blanks (3), and modifying a heating profile. An actual thermal profile of one blank is established, and a singular pressure point is detected in the blank. A difference between the actual thermal profile and a theoretical thermal profile, and a difference between the singular pressure point and a theoretical singular point are measured. The steps are repeated as long as the differences are below a preset tolerance, and the modification of the speed of movement of the blanks is repeated when the speed has not reached a preset final value. Independent claims are also included for the following: (1) a computer program for manufacturing containers from blanks of plastic material (2) a machine for manufacturing containers from blanks of plastic material.
