1. A method of making a laminate comprising:
unwinding a collector flow of a collector material from a collector spool;
unwinding a first lamination flow of a first material from a first lamination spool;
producing a first laminate by laminating the first material to the collector material with a first lamination roller positioned downstream of the collector spool, the first laminate including the first material and the collector material;
unwinding a second lamination flow of a second material from a second lamination spool;
producing a second laminate by laminating the second material to the collector material with a second lamination roller positioned downstream of the first lamination roller, the second laminate including the second material, the first material, and the collector material;
unwinding a third lamination flow of a third material from a third lamination spool;
producing a third laminate by laminating the third material to the collector material with a third lamination roller positioned downstream of the second lamination roller, the third laminate including the third material, the second material, the first material, and the collector material;
controlling the third lamination roller to apply a third pressure for laminating;
controlling the second lamination roller to apply a second pressure for laminating, the second pressure being less than the third pressure;
controlling the first lamination roller to apply a first pressure for laminating, the first pressure being less than the second pressure; and
determining the first, second, and third pressures as a function of a thickness desired for the third laminate, including setting of the third pressure to a value sufficient to spread the third laminate to the thickness and setting the first and second pressures to values insufficient to spread an entirety of either one of the first and second laminates to the thickness.
