The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet. ## Claims ### Claim 1 An in-line lamination system comprising a film slitter aligned along a machine direction and adapted to receive a sheet of film along the machine direction and form film strips from the sheet of film, the film strips aligned along the machine direction in a series of adjacent lanes, a non-woven material supply adapted to provide a first substantially continuous non-woven web and a second substantially continuous non-woven web along the machine direction, and a laminator aligned with the film slitter along the machine direction and configured to receive the film strips, first non-woven web, and second non-woven web and bond selectively the film strips in adjacent lanes alternatingly to one of the first non-woven web or second non-woven web to form a first laminate sheet and a separate second laminate sheet, each of the first laminate sheet and a second laminate sheet having alternating sections of exposed non-woven material and film material. ### Claim 2 (depends on 1) The in-line lamination system of claim 1, wherein the laminator includes adhesive applicators and a pair of lamination nip rollers. ### Claim 3 (depends on 2) The in-line lamination system of claim 2, wherein the adhesive applicators are configured to apply an adhesive material to the first non-woven web and second non-woven web and the lamination nip rollers are configured to force the film strips against the first non-woven web and second non-woven web. ### Claim 4 (depends on 3) The in-line lamination system of claim 3, further comprising print heads configured to apply an anti-bond material to the film strips. ### Claim 5 (depends on 2) The in-line lamination system of claim 2, wherein the adhesive applicators are configured to apply an adhesive material to the film strips and the lamination nip rollers are configured to force the film strips against the first non-woven web and second non-woven web. ### Claim 6 (depends on 5) The in-line lamination system of claim 5, further comprising anti-bond kiss coaters configured to apply an anti-bond material to the first non-woven web and second non-woven web in zones. ### Claim 7 (depends on 1) The in-line lamination system of claim 1, wherein the laminator includes a pair of alignment nip rollers and an ultrasonic welder. ### Claim 8 (depends on 7) The in-line lamination system of claim 7, further comprising anti-bond kiss coaters configured to apply an anti-bond material to the first non-woven web and second non-woven web in zones. ### Claim 9 (depends on 1) The in-line lamination system of claim 1, wherein the laminator includes a first lamination station and a second lamination station, each lamination station is arranged along the common direction and off-set from one another, the first lamination station is configured to receive a first plurality of the film strips and the first non-woven web, the second lamination station is configured to receive a second plurality of the film strips and the second non-woven web, and the first plurality of film strips and the second plurality of film strips each include film strips in non-adjacent lanes. ### Claim 10 (depends on 1) The in-line lamination system of claim 1, further comprising a film supply adapted to provide the sheet of film in a continuous form. ### Claim 11 (depends on 10) The in-line lamination system of claim 10, wherein the film supply is an extruder. ### Claim 12 (depends on 10) The in-line lamination system of claim 10, further comprising a breathable film activation station configured to impart breathability to the film. ### Claim 13 (depends on 10) The in-line lamination system of claim 10, further comprising an elastic film activation station configured to impart elasticity to the film. ### Claim 14 (depends on 10) The in-line lamination system of claim 10, further comprising at least one of a breathable film formation station configured to form the sheet of film into a breathable film and an elastic film formation station configured to form the sheet of film into an elastic film. ### Claim 15 (depends on 1) The in-line lamination system of claim 1, further comprising a slitting station configured to separate the first laminate sheet and the second laminate sheet into strips of laminate material. ### Claim 16 (depends on 1) The in-line lamination system of claim 1, further comprising an alignment station configured to align film strips of the first laminate sheet with film strips of the second laminate sheet in confronting relation to one another. ### Claim 17 (depends on 16) The in-line lamination system of claim 16, further comprising a lamination station configured to bond the first laminate sheet to the second laminate sheet along the sections of exposed non-woven material to form a laminate product. ### Claim 18 (depends on 17) The in-line lamination system of claim 17, further comprising a slitting station configured to separate the laminate product into strips of laminate product. ### Claim 19 An in-line lamination system comprising a film slitter aligned along a machine direction and adapted to receive a sheet of film along the machine direction and form film strips from the sheet of film, the film strips aligned along the machine direction in a series of adjacent lanes, a non-woven material supply adapted to provide a first substantially continuous non-woven web and a second substantially continuous non-woven web along the machine direction, and a laminator aligned with the film slitter along the machine direction and configured to receive the film strips, first non-woven web, and second non-woven web, wherein the laminator is configured to provide means for selectively bonding the film strips in adjacent lanes alternatingly to one of the first non-woven web or second non-woven web to form a first laminate sheet and a separate second laminate sheet, each of the first laminate sheet and a second laminate sheet having alternating sections of exposed non-woven material and film material. ### Claim 20 (depends on 19) The in-line lamination system of claim 19, wherein the laminator includes a first lamination station and a second lamination station, each lamination station is arranged along the common direction and off-set from one another, the first lamination station is configured to receive a first plurality of the film strips and the first non-woven web, the second lamination station is configured to receive a second plurality of the film strips and the second non-woven web, and the first plurality of film strips and the second plurality of film strips each include film strips in non-adjacent lanes.
