Abstract
The mold halves of a tire press are provided with sensors which determine the contact times of a green tire at certain points on the mold surfaces. The timing so obtained is processed by a microprocessor to determine the run-out profile of the tire. The data is further used for determining the average gap between the green tire and the mold surfaces both at the time of mold closure and at the time of first contact between the green tire and the mold surfaces. This data is then used to regulate the closure rate of the mold halves and/or the inflation rate of the green tire. The sensors contemplated include pressure switches, vacuum switches, microswitches, linear variable differential transformers, and thermocouples.
