The present invention refers to a process for bonding flexible films by converting the surface of a first film into a softened state before contacting the softened surface with a second film, a device for carrying out the inventive process as well as a composite body obtained by the inventive process or by the inventive device.

Methods for preparing multi-layer optical laminates include placing an optical film that is free form an adhesive layer between first and second glass substrates that are free of an adhesive layer, placing this laminate under vacuum, and then heating the laminate under pressure to a temperature above the softening temperature of the optical film. The glass substrates are free of an adhesive layer but may include a silane surface treatment. The resulting multi-layer laminate is optically clear and does not show scattering of reflected light by the optical film.

A decorative sheet that includes at least a thermoplastic resin substrate layer, a transparent thermoplastic resin layer and a surface protective layer in this order. The surface protective layer is formed by laminating at least two layers. At least a second surface protective layer, which constitutes an outermost layer that is a layer located furthest from the transparent thermoplastic resin layer among layers constituting the surface protective layer contains an ionizing radiation-curable resin containing a multifunctional hexamethylene diisocyanate oligomer at a weight ratio of 60% or more. The arithmetic mean height of a profile curve measured from the second surface protective layer in accordance with JIS B 0601 is 15 μm or more, and the maximum height of the profile curve is 38 μm or more.

Provided is a laminating apparatus configured to improve the uniformity of the thickness of a laminate to be obtained to improve the yield of a product, such as a laminate. The laminating apparatus includes a pressing device including a first press block that is advanceable and retreatable, a second press block arranged to face the first press block, a first pressing rubber mounted inside the first press block, and a second pressing rubber mounted inside the second press block, the first pressing rubber and the second pressing rubber facing each other, the first pressing rubber having formed on a surface thereof facing the second pressing rubber a convex frame configured to surround a peripheral edge portion thereof.

The present invention refers to a process for bonding flexible films by converting the surface of a first film into a softened state before contacting the softened surface with a second film, a device for carrying out the inventive process as well as a composite body obtained by the inventive process or by the inventive device.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a flange may be configured to couple to the protective film. The flange may aid in the accurate application of the protective film to the electronic device.

The present invention relates to a method for adhesively bonding substrates in film form, wherein one of the substrates has a thermoplastic surface which is converted into a softened state prior to adhesive bonding, and wherein the surface of this substrate that is opposite to the thermoplastic surface is cooled using a cooling roller. Furthermore, the present invention relates to a device for carrying out the method according to the invention.

The method for producing a multilayer covering film includes having a pressure sensitive adhesive layer protected by a liner with a system for controlling adhesion. The method includes a step of forming the adhesion-controlling system, which includes an operation for selectively positioning a polymeric, non-adhesive material composition in microcavities provided on one face of the liner. The invention also relates to a multilayer film produced using this production method and a method for applying this multilayer film.

A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.
