ABSTRACT:
The invention relates to the positioning of rolls to ensure the correct alignment of rolling grooves in the rolls with each other and with the pass line of the product. Hitherto to ensure correct alignment of rolling grooves, repeated trial runs and roll adjustment have been effected until rolling is correct, and when production can recommence. The invention eliminates this problem by predetermining the distances of grooves in a first reference and a second roll from a fixed datum on a base for the roll stand, preferably in a prior calibration stage, which information is stored preferably in a microprocessor, the microprocessor subsequently controlling drive means to move the rolls to align co-operating rolling grooves and align the rolling grooves with the pass line, or to move the second roll with reference to the reference roll to align co-operating rolling grooves, and move roll guides to align the pass line with the rolling grooves.
