Accurate rolling line alignment for forming aluminum heat exchangers

A method for controlling an adjustable rolling line, the method comprising:

• obtaining, while the adjustable rolling line is operating, a first measurement of a first convolution spacing of first corrugated material formed from coiled material by a pair of primary rollers and one or more adjustable finger tensioners;
• determining, based on the first measurement, one or more first adjustments to the one or more adjustable finger tensioners;
• adjusting, based on the one or more first adjustments, the one or more adjustable finger tensioners;
• obtaining, while the adjustable rolling line is operating, a second measurement of a second convolution spacing of second corrugated material formed from the first corrugated material by a pair of adjustable restrike rollers;
• determining, based on the second measurement, one or more second adjustments to the pair of adjustable restrike rollers;
• and
• adjusting, based on the one or more second adjustments, the pair of adjustable restrike rollers.

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware and storing instructions that, when executed by the data processing hardware, cause the data processing hardware to perform operations comprising:
• obtaining, while an adjustable rolling line is operating, a first measurement of a first convolution spacing of first corrugated material formed from coiled material by a pair of primary rollers and one or more adjustable finger tensioners;
• determining, based on the first measurement, one or more first adjustments to the one or more adjustable finger tensioners;
• adjusting, based on the one or more first adjustments, the one or more adjustable finger tensioners;
• obtaining, while the adjustable rolling line is operating, a second measurement of a second convolution spacing of second corrugated material formed from the first corrugated material by a pair of adjustable restrike rollers;
• determining, based on the second measurement, one or more second adjustments to the pair of adjustable restrike rollers;
• and
• adjusting, based on the one or more second adjustments, the pair of adjustable restrike rollers.
