Abstract:
1. An apparatus comprising: an energy source adapted to provide curing energy; a first patterned roll comprising a first plurality of regions opaque to the curing energy disposed on a first substrate transparent to the curing energy, the first plurality of regions defining a first raised pattern; a second patterned roll comprising a second plurality of regions opaque to the curing energy disposed on a second substrate transparent to the curing energy, the second plurality of regions defining a second raised pattern; one or more feed rolls adapted to provide a web and to feed the web into contact with the first and second patterned rolls, the web having first and second sides; a first dispenser adapted to dispose a curable material onto the first side of the web, or onto the first patterned roll before the web contacts the first patterned roll; a second dispenser adapted to dispose a curable material onto the second side of the web, or onto the second patterned roll before the web contacts the second patterned roll; and a control arrangement configured to rotate the first and second patterned rolls such that the first and second raised patterns are imprinted in the curable material on the first and second sides of the web while the web is in continuous motion, and the first and second raised patterns are maintained in continuous registration on the first and second sides of the web to within 100 micrometers.
