Disclosed is a method for manufacturing an optical lens including the following successive steps: a step of providing an optical lens attached to a blocking piece; a step of laminating a functional film on a surface of the optical lens; a step of obtaining an assembly constituted by the blocking piece, the optical lens and the functional laminated film; a step of cutting the excess film directly on the assembly, so as to reduce the film shape; and a step of deblocking the optical lens with the film, and the blocking piece.

An applicator is provided for applying protective films to electronic device displays. The applicator includes a base, a screen protector, and a squeegee. The base includes a pocket for receiving an electronic device. The screen protector is affixed to the base so as to overlie an electronic device. The screen protector preferably includes three layers including a protective film, cap sheet, and back liner. The squeegee is provided for removing the back liner and for simultaneously affixing the protective film to an electronic device.

A flat laminate element made of thermoplastic is hot-formed in a two-stage method. In a first stage, the flat laminate which includes film(s) and/or panels(n) is placed on a flat frame-shaped pallet and is heated to a forming temperature in a heating zone between two flat heat screens in a contactless manner. The edge zone of the hot flat laminate element lies on the pallet such that the laminate piece cannot be clamped in a first laminate direction but rather can be slide on the pallet in this direction. Two non-flat rigid contours which are identical or largely identical act on two opposing parallel laminate edge sections uniaxially and perpendicularly to the laminate plane and only in the first laminate direction, i.e. monodirectionally, and shape the entire heated laminate element into a monodirectionally molded blank.

An apparatus for applying the film to the substrate includes a bed having a substrate placement surface and a selectively positionable tack bar, a roller support moveable over the span of the bed, and including the location of the positioning bar, and a roller rotatably supported to the positioning bar and moveable over the bed in response to movement of the roller support with respect to the bed. In another aspect, the tack bar is of the same thickness, or slightly less thick, as the substrate onto which the film is to be applied, such that a portion of the film to be applied can be secured thereto and not on the substrate before the backing is removed from additional portions of the film, such that the tack bar supports an end of the film in substantially the plane of, or slightly below the plane of, the substrate.

An examination of microwave oven-resistant sheets for heat-insulating foamed paper containers revealed that blisters occur in the containers in the course of microwave oven treatment. That is to say, the present invention addresses the problem of providing a sheet for heat-insulating foamed paper container such that no blisters occur during microwave oven treatment. The present inventors have found that the problem to be solved by the present invention can be solved by a method for producing a sheet for a heat-insulating foamed paper container, wherein an air gap of 150 mm or larger, a drawing speed of 65 m/minute or lower, and a polyethylene resin density of 923 to 930 kg/m.sup.3.

[Problem] The problem that unevenness occurs in the foam layer and the insulating property deteriorates when lamination is carried out at high speed was clarified in a process for producing a sheet for a foam insulating paper container. Specifically, the problem addressed by the present invention is to provide a sheet for a foam insulating paper container that can be foamed without unevenness even when laminated at high speed.

[Solution] The present inventors discovered that the problem addressed by the present invention can be solved by a method for producing a sheet for a foam insulating paper container in which a polyethylene resin is laminated on at least one side of a paper substrate, wherein the method for producing a sheet for a foam insulating paper container is characterized in that the lamination conditions are an air gap of 150 mm or greater and a take-off speed of 70 m/min or higher.

The present disclosure relates to the technical field of film sticking, more particularly to a film applicator, a sticking film and a film-sticking assembly. The film applicator includes a main body portion, a pulling opening and a fixing portion. When using, the electronic product is positioned at the mounting slot and the sticking film is positioned on the fixing portion, the pulling portion is positioned between the screen and the release film layer, with a gap existed therebetween. The free end of the pulling portion is pulled to separate the release film layer and the tempered film to make the side with static electricity to attract the dust on the screen. By configuring the film applicator with the electrostatic layer, steps of pasting and dust removal are almost simultaneously carried out, and the sticking film is limited to a small space to prevent impurities and improve pasting quality.
