Embodiment Construction

[0033] attached image 3 and 4 A system 10 for making an elongated and continuous web of lenticular lenses 30 is shown. The lenticular sheet 30 may be rolled into a continuous sheet roll 40 . A lenticular pattern-forming device 21 for making the lenticular sheet 30 is briefly described here, and the detailed structure of the device 21 will be described in more detail below. The system 10 includes a support 19 supporting a lenticular arrangement 21 . System 10 also includes a pair of rollers 20 mounted on frame 19 . The lenticular device 21 comprises a housing 22 having an outer surface 24 . The outer surface 24 has a groove structure 26 which is preferably engraved into the outer surface 24 around the circumference. In other words, the groove structures 26 are distributed around the circumference of the outer surface 24 . The grooves 28 form a groove structure 26 which runs parallel along the outer surface of the cylinder. A housing 22 is placed longitudinally between t...

Abstract

The present invention provides a lenticular lens and method for manufacturing the lens, and in particular when the lens is a lenticular lens web, such that finishing operations (e.g., cutting, laminating, etc.) and various end-use applications of the lens (e.g., labeling) can be achieved or accommodated in-line with the manufacture of the lens web. A lenticular pattern-forming device comprising a housing that is rotatable about a central longitudinal axis is disclosed. The housing has an outer surface having a groove pattern. The groove pattern includes circumferentially and longitudinally extending grooves on the outer surface and the grooves have substantially equal groove widths. The longitudinally extending grooves are substantially parallel with the central longitudinal axis and grooves cover the outer surface of the housing. In addition, the invention further includes a method of using the lenticular pattern-forming device to produce a lenticular lens web, which can be used to make a lenticular image web. The image web can be used to create end products such as wallpaper, banners, labels and the like.

Description

technical field [0001] The present invention relates generally to convex lenses, and more particularly, the present invention relates to devices, systems and methods for fabricating convex lenses. Background technique [0002] The convex lens takes the form of a transparent plastic plate or sheet, and the layer usually includes a set of identical curved or ribbed surfaces (i.e., a convex lens structure) formed (such as by casting, coating deposited, embossed, extruded or co-extruded) on the front side of the plastic sheet. The back of the lens is usually flat. Each microlens or individual lens is part of an elongated cylinder that extends the entire length of the underlying image and is focussable on it. Other lens shapes or profiles are also possible (eg pyramidal, trapezoidal, parabolic or similar). In general, the selected convex lens should be suitable for the underlying image and the distance at which the viewer usually views the image. Various different types of co...
