Abstract
A method for creating a registered pattern on a metal coil includes providing a pattern applicator roll and a drive motor for rotating the roll, moving the coil into contact with the applicator roll to permit it to create a pattern sequentially on the moving strip from the coil, measuring the pattern length and comparing the same with the desired pattern length, and adjusting the speed of rotation of the pattern applicator roll if the measured pattern length departs from the desired pattern length by a predetermined amount. Preferably, coil line speed is also monitored. A microprocessor may be used to effect the comparison between the desired pattern length and the actual pattern length. Apparatus for creating a registered pattern on a metal coil includes a pattern applicator roll which has the strip from the coil moved into contacting relationship therewith, an appropriate drive motor to drive the roll, and apparatus for monitoring coil line speed, pattern length and motor speed. A microprocessor stores the desired pattern length and receives information regarding line speed, pattern length, and motor speed, and where an adjustment is desired, either speeds up the applicator roll …
