摘要： 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.
摘要翻译：第一片（10,32,56）由涂布机（47）涂覆，图案包括低粘度粘合剂的多个离散区域（12,34），然后通过以下方式层压到第二片材（70）上：成对辊式层压机（62）。粘合剂的粘度足够低，并且层压机的压力足够高，使得多个粘合剂区域（12）在层压期间被扩散并且从两个片材之间排出空气，从而形成仅填充粘合剂的单个粘结区域没有粘合剂的片材之间的空间基本上超过片材的边缘，并且没有气泡或空隙被夹在片材之间。在优选的图案中，所述区域（12）包括粘合剂条，其间具有间隔（14），所述条基本上平行于层压方向（16）。条纹可以通过在第一片的前缘（18）处的连接区域（20）连接，以增强靠近该边缘的层压，并且可以在它们的远端或尾端处切口或凹进（28）以平滑粘合剂前端在完成层压通行证。优选地，粘合剂是可辐射固化的，允许在层压之后需要时两个片材的相对移动，并且单个结构域中的粘合剂然后通过暴露于合适的辐射而固化。该方法特别适用于在形成透镜深度图像印刷物时将透镜覆盖片层压到线状图像片。

摘要： The invention is a viewer for slides having three-dimensional and/or animation type lenticular images recorded thereon in image line sets. In detail, the invention includes a frame. The frame includes a slot for receiving the slide therein having an open end at the top or side of the frame and a closed off opposite end, the slot in a planer relationship with the front and rear walls. The front wall includes a lenticular lens mounted in a planner relation therein, the lens having an internal side forming a portion of the wall of the slot; the lens having a plurality of lenticules therein. The end opposite the open end of the slot is aligned with the lenticules of the lens and positioned within the frame such that a slide positioned in the slot in contact with the opposite end of the slot will have the center of the image line sets in substantial alignment with the center of the lenticules of the lenticular lens. In a second embodiment, the viewer includes only a lenticular lens having a protursion at one end thereof for positioning the slide such that a slide positioned on the protrusion will have the center of the image line sets in substantial alignment with the center of the lenticules of the lenticular lens.
摘要翻译：本发明是用于在图像行集中记录有三维和/或动画型透镜图像的幻灯片的观看者。详细地说，本发明包括一个框架。框架包括用于接收其中的滑动件的槽，其中在框架的顶部或侧面具有开口端，并且在相对端处封闭，该槽与前壁和后壁呈平面关系。前壁包括以其中的计划关系安装的双凸透镜，透镜具有形成狭槽的壁的一部分的内侧; 透镜在其中具有多个微透镜。与槽的开口端相对的端部与透镜的微透镜对准，并且定位在框架内，使得位于槽中的与狭槽的相对端接触的滑块将使得图像线组的中心基本上与双凸透镜的微透镜的中心对准。在第二实施例中，观察者仅包括一个双凸透镜，其在其一端具有一个端部，用于定位滑块，使得位于突起上的滑块将使图像线的中心与双凸透镜。

摘要： A lenticular device is disclosed having a lens array with one or more lenticular convex ridges joined by cusped or concave valleys forming lens elements on one of its surfaces. In addition, the lenticular array is uniformly separated from a message transmitting surface by an air space directly related to a field of view of no more than 30.degree. determined by the converging light rays at the focal point. The carrier sheet or message is a plurality of messages resolved from a series of linear segments in the form of binary lineations placed in focus relative to the lens array. By establishing a proportional relationship between lens aperture and focal length, the rate of message change is predetermined for any prescribed viewing situation. Surface interference caused by reflection, chromatic diffraction, and other light loss is controlled by the relationship of optical design, and optical quality, coupled with other structural elements.
