    Abstract: A roll to roll microreplication apparatus is described. This apparatus forms a microreplicated article including a web having first and second opposed surfaces. The apparatus includes a first patterned roll, first nip roll and first coating die; the first coating die is disposed adjacent the web substrate first side and the web substrate is disposed between the first patterned roll and first nip roll. The first nip roll touches the web substrate second side and the first patterned roll touches the web substrate first side. The apparatus includes, a second patterned roll, second nip roll and second coating die, the second coating die is disposed adjacent the web substrate second side and the web substrate is disposed between the second patterned roll and second nip roll. The second nip roll touches the web substrate first side and the second patterned roll touches the web substrate second side. A drive assembly is configured to rotate the first patterned roll and the second patterned roll such that the first and second rolls maintain a continuous registration within 100 micrometers. Methods of making a microreplicated article are also disclosed.

    Abstract: Methods and systems for determining longitudinal position of an elongated web are described. Sensors are used to detect one or more substantially continuous fiducial marks disposed longitudinally on the web. The sensors generate signals associated with the fiducial marks. A position detector receives the signals and determines a longitudinal position of the web using the sensor signals. The fiducial marks may be periodic fiducial marks, such as sine and/or cosine marks on the web and/or may be piecewise continuous marks. The coarse longitudinal position of the web can be determined based on periodically recurring features of the fiducial marks. The fine longitudinal position can be determined based on continuous portions of the fiducial marks between the periodically recurring features.
