DEVICE FOR MANUFACTURING PANEL WITH FUNCTIONAL FILM, METHOD OF ITS MANUFACTURING, AND PANEL

摘要

The present invention relates to a technique for affixing a functional film on a panel surface having a curvature in three dimensional directions with a pushing roller. Even if the pushing roller has a mechanism for controlling a roller pressure to be uniform on the basis of the curvature on the panel surface in the roller travelling direction, since the panel surface has a curvature in a plane perpendicular to the roller travelling direction, at the first and second end portions of the panel surface intersecting the above plane, there arises a problem that the functional film can not be affixed uniformly due to a difference in roller pressure, generation of air bubbles and so on. In the present invention, addition to the main pushing roller unit (3) used in the background art, pushing roller units (41 and 42) each having an equalizer (4E) which allows follow-up displacement according to variation of the curvature in the roller travelling direction (X) at first and second end portions (E1 and E2) of a panel surface (1S) are disposed behind the main pushing roller unit (3) relative to the roller travelling direction on the sides of the first and second end portions, respectively, and pressure control mechanisms (9, 39 and 40) for making the roller pressures uniform are provided for the respective pushing roller units. Then, the main pushing roller unit (3) travels along the roller travelling direction (X) while pushing the functional film (2) against the panel surface (1S), followed by the two follow-up displacement pushing roller units (41 and 42) which are displaced in response to the travel of the main pushing roller unit while pushing the functional film (2) against the panel surface (1S). The present invention is applied to a CRT display unit and the like. <IMAGE>
