PURPOSE:To prevent the generation of stripes and that of optical strain at the time of reproduction by integrally bonding a hologram sheet to other sheet by a tape and fixing one end part of the integrated one while connecting the other end part thereof to a wt. through a fixed pulley. CONSTITUTION:Flat glass 2 is placed on a placing stand 3 at a predetermined position. A part of a PET sheet 6 is cut into a size slightly larger than that of a hologram sheet 1 and the hologram sheet 1 is arranged to a hole part to be bonded to the PET sheet 6b by an adhesive tape 7 to be integrated therewith. Next, both end parts of the PET sheet 6 are bonded to rigid support members 8, 8' such as aluminum angles by double adhesive tape and one end thereof is bonded to a bracket 10 through yarns 9, 9' while the other end thereof is bonded to two wts. 12 through fixed pulleys 11, 11. The PET sheet 6 containing the hologram sheet 1 is pressed to the flat glass 2 by rolls 6 in such a state that the flat glass 2 is heated by a heating apparatus 22. The rolls 16 are allowed to run at a constant speed by the driving of an electromotor 20 to bond the hologram sheet 1 to the flat glass 2. |
