A thermoregulation system of rotating metal cylinders in plants for the extrusion and conversion/transformation of plastic films includes heating elements applied to each rotating cylinder, wherein the heating elements are infrared heating elements, and wherein the rotating cylinder includes a metal tube rotating around a fixed shaft, which is rigidly connected to two side plates.

This application relates to an imprinting apparatus and method. In one aspect, the imprinting apparatus applies pressure between a master substrate and a polymer film to transfer a pattern formed on the master substrate to the polymer film. The imprinting apparatus includes a plurality of coils and the surface of the master substrate is heated by an electromagnetic field induced by the plurality of coils. Through holes are defined in each of the plurality of coils, and support bars are inserted into the through holes. The positions of the plurality of coils are changed corresponding to the master substrate.

An anti-glare film and a method of fabricating the same. The anti-glare film includes a transparent substrate, a photocurable resin layer stacked on one surface of the transparent substrate, and a plurality of amorphous patterns formed on a surface of the photocurable resin layer. The anti-glare film can provide excellent diffusion of light, exhibit excellent brightness without deterioration of transmittance, and provide excellent front brightness and visibility when applied to polarizing plates and display devices.

Methods, apparatus and systems are disclosed by which patterned layers can be formed in a roll-to-roll process using a variable and programmable means for applying liquids and solutions used in the patterning process.

The present invention is a roll as may function as an anvil roll that comprises protrusions on its outer surface, that are outwardly or z-directionally oriented arcs of an arc wire such as wavy wire or an axially canted helical coil extending along a length or x-direction, which are pinched perpendicularly to the z- and x-direction. Such anvil rolls may be used to treat materials such as web materials, such as by embossing or bonding these web materials. In a particular application, such rolls may interact with an ultrasonic sonotrode.

Provided is a decorative sheet that, due to an asperity profile, creates a highly textured impression, such as a contoured impression, three-dimensional impression, impression of depth, and the like, even after being molded, and that has exceptional surface flatness. This decorative sheet has a layer that includes at least a transparent resin film layer, the layer that includes at least the transparent resin film layer having on one surface thereof an asperity profile having recesses that reach the transparent resin film layer, and includes an area in which the depth (d) of the recesses of the asperity profile, and the thickness T from the start point of the depth (d) to the surface on the opposite side from the surface that has the asperity profile in the layer that includes the transparent resin film layer, satisfy the relationship (d)/T×100=5-10, and is intended for use as a decorative resin molded article in which a molding resin is laminated to the surface having the asperity profile.

Systems and methods that prevent oxygen inhibition of a light-initiated polymerization reaction by forcing the oxygen away from the reaction surfaces. In some embodiments, oxygen is purged by bringing a planarizing surface (e.g., a thin transparent film and/or a transparent planar surface) into contact with a layer of UV curable material disposed on a workpiece and then moving the planarizing surface away from the workpiece once the UV material is cured.
