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.

Claims

1. A method of making a multi-row, multi-column laminated product comprising the steps of:

providing a rectangular paperboard sheet with intelligence printed on at least one side thereof, said sheet having a leading edge, two perpendicular side edges and a trailing edge parallel to said leading edge,

feeding the leading edge of the paperboard sheet in a first direction and cutting out a narrow transverse segment in the middle of said sheet to produce a transverse gap, leaving connecting portions at each end of the transverse gap, said transverse gap being parallel to said 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 said side edges and perpendicular to said leading edge with cutters, thereby to remove strips of waste from between adjacent panels, and

feeding said leading edge into a laminating roller nip with laminating sheets prior to cutting with said cutters into said 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 said transverse gap, whereby a multi-row, multi-column laminated product is produced after the paperboard sheet and laminating sheets leave the laminating roller nip.

2. In the method of claim 1, and additionally cutting selvage from the sides of said paperboard sheet to remove selvage and said connecting portions, all concurrently with cutting strips of waste from between adjacent panels.

3. In the method of claim 1, and continuing laminating until said trailing edge passes through said laminating nip, and trimming the leading edge, trailing edge and side edges to provide finished edges.
