A first sheet (10, 32, 56) is coated by a coater (47) with a pattern comprising a plurality of discrete domains (12, 34) of a low-viscosity adhesive and is then laminated to a second sheet (70) by a paired-roller laminator (62). The viscosity of the adhesive is sufficiently low and the pressure of the laminator sufficiently high that the plurality of adhesive domains (12) are caused to spread during lamination and to displace air from between the sheets, forming thereby a single domain of adhesive which just fills the space between the sheets without adhesive being extruded substantially beyond the edges of the sheets and without air bubbles or voids being entrapped between the sheets. In a preferred pattern, the domains (12) comprise stripes of adhesive with spaces (14) therebetween, the stripes being substantially parallel to the direction of lamination (16). The stripes can be joined by a connecting domain (20) at the leading edge (18) of the first sheet to enhance lamination near that edge, and can be notched or indented (28) at their distal or trailing ends to smooth the adhesive front at the completion of the laminating pass. Preferably, the adhesive is radiation curable, allowing relative movement of the two sheets if desired after laminating, and the adhesive in the single domain then is cured by exposure to appropriate radiation. The method is especially suitable for laminating a lenticular overlay sheet to a lineiform image sheet in forming a lenticular depth image print.

A lenticular print (13) having image bundles (19), and method and apparatus for aligning and centering image bundles (19) in the print (13) under lenticules in a lenticular overlay (11). On the print are provided one or more two-dimensional fiducial indicia (17) containing one or more angular or linear alignment elements (18, 29, 45) disposed at about two lenticules widths apart.

An image sheet (12) is coated with a radiation curable adhesive (48) at a coating station and then laminated to a lenticular array sheet (20) at a laminating station (50). A lamination of the image and array sheets is then positioned on an aligning station (56) where the lenticules of the array sheet are aligned with the image lines (16) of the image sheet. The adhesive is set at a curing station (60).

Apparatus and methods for assembling depth image systems

To cinch a web end portion onto a core, the core is center driven by a core driving mechanism at an outer peripheral speed in excess of the speed at which the web end portion is fed to and threaded around the core. After the web end portion is cinched onto the core and the web wound to form a roll of predetermined diameter, the core drive mechanism is disengaged from the core to terminate the core center drive. The outer surface of the roll further substantially simultaneously engages a roll surface drive mechanism which is normally spaced from the core for surface driving the roll.

Web cinching and winding apparatus and method

A card injecting apparatus in which an air gun directs a jet of air underneath a stack of articles for lifting the articles above a supporting surface to form a space between the lowermost article and supporting surface. Additional jets of air are directed by the air gun for injecting a card into the space. The air gun is formed of two portions, one portion defined by a stationary member and the other portion defined by a slider member which is movable relative to the stationary member between two positions for successively feeding cards from spaced apart hoppers to the air gun.
