Abstract
A method of making a multi-row, multi-column laminated product including the steps of providing a printed rectangular paperboard sheet having a leading edge, two perpendicular side edges and a trailing edge parallel to the leading edge, feeding the leading edge of the sheet in a first direction and cutting out a narrow transverse segment in the middle of the sheet to produce a transverse gap, leaving connecting portions at each end of the transverse gap, the transverse gap being parallel to the leading edge, gripping the paperboard sheet and feeding its leading edge in the same first direction and continuously cutting the paperboard sheet into adjacent panels in a direction parallel to the side edges and perpendicular to the leading edge, thereby to remove strips of waste from between adjacent panels, and feeding the leading edge into a laminating roller nip with laminating sheets prior to cutting into the transverse gap and continuously gripping the sheet between its side edges at a distance from the laminating roller nip that is less than the distance between the leading edge and the transverse gap.
