Abstract

A trailing end of a leading metal strip is joined to a leading end of a trailing metal strip by first overlapping the leading end of the trailing strip with the trailing end of the leading strip and then clinching the ends together at the overlap by pressing at least one punch of a joining tool into one of the strips at the overlap sufficiently to complementarily deform both of the strips. The thickness of the leading and trailing ends is measured and a depth of engagement of the punch into the strips is controlled in accordance with the measured thickness.
