Abstract
A laminator for applying pre-printed labels to a single face corrugated web to form double face corrugated sheets utilizes a control system including accurate leading and trailing edge detection of the labels to custom cut the corrugated web to match the label length in a manner which assures complete and uniform coverage of the glued flute tips of the corrugated web by the labels. The labels are fed non-stop as a series of spaced sheets into a laminating nip to join the leading edge of the traveling single face corrugated web. A positioning nip upstream of the laminating nip varies the speed of the incoming sheets to accurately match sheet leading edge to web leading edge. Detection of the sheet trailing edge triggers operation of the web cut-off knife to accurately match the corresponding cut trailing edge.
