20210031503 · 2021-02-04 ·

A method of laminating a contoured part including heating a flexible membrane, positioning the heated flexible membrane into thermal contact with the contoured part, maintaining the heated flexible membrane in thermal contact with the contoured part to raise a surface temperature of the contoured part, moving the flexible membrane out of thermal contact with the contoured part, positioning a laminate between the flexible membrane and the contoured part, conforming the laminate to a surface of the contoured part, and heating the conformed laminate and contoured part to adhere the conformed laminate to the surface of the contoured part. The laminate may be conformed to a surface of the contoured part by applying a vacuum between the flexible membrane and the contoured part.

POLARIZING FILM, METHOD FOR MOLDING POLARIZING FILM, AND METHOD FOR PRODUCING POLARIZING LENS

A polarizing film having a molded shape, in which a difference in average transmittance of the polarizing film at a wavelength of 400 to 700 nm is 5% or less before and after molding the shape of the polarizing film. In addition, when molding the polarizing film into a shape such as a curved surface, the polarizing film is heat-treated in a temperature range of Tg20 C. or higher and Tg+10 C. or lower, where Tg is a glass transition point of a resin constituting the polarizing film. Further, one chamber is divided into a first space and a second space by the polarizing film disposed in the chamber, and the polarizing film is transfer-molded along a molding surface by a differential pressure generated by making a pressure in the first space and a pressure in the second space different from each other.

Method for manufacturing a lighting device

A method is provided, wherein a lighting device (200, 300, 400, 500) comprising an at least partly light transmitting envelope (110) and a solid state light source (120) is manufactured. The method comprises arranging (710) an at least partly light transmitting plastic material (140) in a mold (130) having a surface structure (132) arranged on an inner surface portion of the mold and blow molding (720) the plastic material so as to form the envelope. During the blow molding, the surface structure is at least partly transferred to the at least partly light transmitting plastic material, thereby forming an optical structure (150) on a portion of an outer surface of the envelope. The envelope is then removed (730) from the mold and arranged (740) to at least partly enclose the solid state light source. The optical structure may be formed to generate a desired optical effect.

METHOD AND DEVICE FOR PRODUCING A 3-D SUBSTRATE COATED WITH A LAMINATE
20210023766 · 2021-01-28 ·

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.
