A lamination system includes a film supply, a non-woven material supply, and a laminator. 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.
Claims20
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.
