The present invention provides a method for improving visibility of an image display device which is capable of providing an image display device excellent in anti-reflection properties and bright-field contrast even using an optical layered body including a light-transmitting substrate having in-plane birefringence, such as a polyester film. The method of the present invention is a method for improving visibility of an image display device that has an optical layered body including a light-transmitting substrate having in-plane birefringence and an optical functional layer disposed on one surface of the substrate. The method includes the step of disposing the optical layered body such that the slow axis showing a greater refractive index of the light-transmitting substrate is in parallel with the vertical direction of a display screen of the image display device.

The invention relates to the detection and use of film topography (23) of a film web (13, 40, 51) produced in blow film or casting film methods for improving the quality of the film web (13, 40, 51). In particular, film topography (23) can be quantitatively detected using said the invention. In another aspect of the invention, the film topography (23) is analysed using a pattern recognition algorithm and is optionally allocated an error image (50). This information is used in order to improve the quality of the film web (13, 40, 51) by controlling action recommendations dependent on the error image and to quantitatively detect the flatness of a film web (13, 40, 51). The invention also relates to an influencing element (30) for influencing the properties of a film web (13, 40, 51) in the position where the film topography (23) is determined.

The invention relates to a method for monitoring a film quality in the production of a plastic film, comprising the following steps: determining a first temperature (10) of a film material (1) of the plastic film during a transport of the film material (1), in which the film material (1) is cooled along a conveying direction (2) of the film material (1). The invention further relates to a film machine (50) comprising a device for monitoring a film quality in the production of a plastic film.

Polyvinyl acetal films with less blocking tendency and which allow for escape of gas during laminating to form laminated composities are prepared by a process for embossing a film comprising plasticized polyvinyl acetal with a roughness Rz on at least one surfaces of 20 to 100 m by the steps of a. extruding of plasticised polyvinyl acetal to a film with a stochastic roughness of the surfaces of Rz =1 to 70 m, b. embossing at least one surface of the film obtained in step a) with channels having a depth of 5-50 m, a width of 10-200 m and a pitch of 50-2500 m, wherein c. the surface roughness of the elevations between the channels is at most 20% lower as obtained in step a).

Provided is a production apparatus capable of producing a flexible tube whose hardness is naturally varied along the length direction thereof. This mixing valve includes: a first valve configured to distribute a first resin to a resin supply path and a resin discharge path; and a second valve configured to distribute a second resin to the resin supply path and the resin discharge path. In the mixing valve, the mixing proportion between the first resin and the second resin is increased or decreased in association with molding of the flexible tube, by changing a distribution ratio of the first resin in the first valve and a distribution ratio of the second resin in the second valve while keeping constant the total of the supply mounts of the first resin and the second resin supplied to a die.

The invention relates to an apparatus and to a method for film production and/or film processing, characterized by a device for determining the flatness and/or evenness of the film and for further processing and/or outputting the determined results.

The invention relates to novel processes for the lamination of semi-crystalline, high-melting point, low glass transition polymeric films, which are extruded and subsequently laminated on various thermally sensitive substrates to form laminated medical device constructs in a specific time interval to allow low processing temperatures to avoid polymer film and/or substrate degradation or heat-related distortions. Also disclosed are laminated medical device constructs made from such processes.
