Abstract
Official abstract text for this publication.
An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.
First claim
Opening claim text (preview).
We claim: 1. A method for patterning an opaque web having a first side and a second side, the method comprising steps of: patterning a curable material onto a web having a first side and a second side with a first patterned roll and a second patterned roll, the first patterned roll comprising a first plurality of raised opaque regions disposed on a transparent substrate and the second patterned roll comprising a second plurality of raised opaque regions disposed on a transparent s…
