US Patent:

50819232, Jan 21, 1992

Filed:

Dec 24, 1990

Appl. No.:

7/633009

Inventors:

Philip J. LaMantia - Verona PA
George Hardick - Pittsburgh PA
Ralph Campbell - Pittsburgh PA

Assignee:

Enamel Products & Plating Company - McKeesport PA

International Classification:

B44B 500

US Classification:

101 32

Abstract:

A method for creating a registered embossed pattern on a metal coil includes providing a pattern applicator roll and a drive motor for rotating the roll, moving the coil sequentially into contact with the applicator roll means and permit it to create a pattern on the moving strip. Measuring the pattern length and comparing the same with the desired pattern length. 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 embossed 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 where the pattern length is longer than the desired pattern length, or reduces the applicator roll speed, if the pattern length is less than the desired pattern length.
