    • 专利摘要:
    A stretching frame and vacuum former having an identical geometric shape with the vacuum former being proportionally reduced in peripheral dimensions, permits a stretched molecularly-oriented, light-polarizing, organic film having a uniform direction of polarization to be bonded to a substrate without distorting the direction of polarization. The method is practiced by supporting the molecularly-oriented, light-polarizing, organic film in contact with the edge of the vacuum former with the vacuum former being located substantially equidistant from the stretching frame and then a vacuum is applied to the chamber of the vacuum former to draw the film down onto the optical element. By utilizing a stretching frame and vacuum former having identical geometry, the uniform direction of polarization is not distorted by uneven stretching of the organic film as it is drawn down into contact with the glass element by the reduced pressure.

    (54) DEVICE FOR COVERING THE SURFACE. OPTICAL ELEMENT LIGHT-POLARIZING CAPTIVE
    view from above; in FIG. 5 - the same, front view,
    The vacuum moulder 1 (Fig. 1) contains a group of optical elements 2 placed on the holder 3. The tension frame 4 is positioned around the vacuum moulder on the supports 5.
    The rectangular-shaped vacuum moulder (Fig. 2) has parallel sides b and 7 and ends 8 and 9. The bottom 10 of the vacuum moulder 1 and its partial sides 6-9 have many grooves 11 that allow air to be sucked through vacuum through the channel 12. The rim 13 of the vacuum moulder provides a continuous smooth surface in contact with the organic film 14.
    The rim 13 must have an edge lying in the same plane in order to obtain a good tightness without distorting the polarization direction of the organic film.
    The vacuum moulder 1 is mounted on a stand 15, which can be manually moved in a column 16 having a bore hole 17 in which the stand 15 is placed (FIG. 3). A male screw 18 with an external thread is screwed into a threaded hole 19. By hand-spinning button 20, the operator can position the vacuum molder to the desired position relative to the organic film using a locking screw 18. For convenience, column 16 can be mounted on base 21 to support the tension frame it was also possible to mount on this basis.
    The duct 12 is located vertically and connected to a horizontal pipe 22, which can be connected to a source of reduced pressure.
    The grooves 11 on the inner side surfaces of the ends 8 and 9, the walls 6 and 7 and the bottom 10 are cut in the raised shoulder extending along the periphery, having a vertical portion 23 and a horizontal portion 24 that holds the holder at a distance from the surface 25 of the bottom 10 forming device, providing a passage for air between the channel 12 and the grooves 11.
    The tensioning frame (Figures 4 and 5) can have longitudinally located clips 26 and 27 connected to each other by means of hinged levers 28 and 29. The clips 26 and 27 have fixed 30 and swinging parts 31.
    After the organic film is prepared for tension in the usual known manner, the opposite
    The edges of the film are clamped. 26 and 27 and pull, pushing the pivot arms until they take a linear form.
    In order to facilitate the installation of the tension frame 4 together with the tension film, support pins 32 are provided in the supports 5, which are included in the recesses in the upper part of one pair of corresponding supports 5.
    For a better tension of the polarized organic film, the holder is provided with apertures 33 for accommodating optical elements. The surface 34 of the latter is located at several points of the top 35 of the holder. Thus, when the film 14 is in contact with the rim 13 before creating a vacuum, all the optical elements are at an equal distance from the surface of the specified film and are located in the center of space, inside the rim. When vacuum is created, air is sucked through channel 12, pressing the film down until it contacts the surface 34 of the optical elements.
    The clamps 26 and 27 of the frame 4 need to be parallel and equally spaced from the longitudinal sides of the vacuum moulder. When the frame, and 4 is on the supports 5, the geometry of the clamped film and the geometry of the moulder formed by the rim 13 are identical, which allows the film to be pressed to the surface of the element with a predetermined tension pattern, which leads to a uniform polarization direction without causing noticeable tension. wives
