Abstract
A system in which a substrate having a number of longitudinally-extending patterns thereon is slit along longitudinally-extending parallel lines intermediate the patterns so that a longitudinally-extending portion between each pair of patterns may be removed. The substrate, with the portion(s) removed, is then guided between plastic sheets, and the plastic sheets are sealed to each other along the area from which the substrate portion(s) has been removed and along the outside edges of the substrate. The substrate is aligned relative to the slitter using a system that includes a fixed guide roll the axis of which is parallel to and spaced from the slitter and a second guide roll mounted so that its axis is rotatable relative to the axis of the fixed roll in a plane parallel to and about an axis perpendicular to the axis of the fixed guide roll. A sensor intermediate the fixed and second guide rolls senses the transverse position of substrate passing from the second guide roll to the fixed guide roll, and rotates the second guide roll to shift the substrate transversely when transverse misalignment is detected. The gaps in the slitter and guide through which the substrate passes are only slightly thicker than the substrate so as to prevent wrinkling.
