Abstract

PURPOSE:To permit to decorate the picture of hologram quickly and continuously by a method wherein a positioning mark, formed on a decorated sheet previously, is detected to effect the movement as well as stopping at a predetermined position of the decorated sheet automatically. CONSTITUTION:The picture 22 of hologram, decorated on the base material 21 of belt type sheet, is formed on the same material 21 while a mark 23 for positioning in lateral direction and another positioning mark 24 in running direction are formed on the same material 21. A decorated sheet 4 is controlled in the running position thereof by upper and lower guide rolls 6 so to run between molds 1a, 1b while the positions in the running direction and the lateral directions thereof are detected by sensors 8, 9 so as to be stopped at a predetermined position. Subsequently, the decorated sheet 4 is contacted closely with the mold 1a and is fixed to the mold 1a by evacuating through a vacuum hole 2. Subsequently, the molds 1a, 1b are clamped and molten resin 30 is injected through an injection port 3. After the resin is cooled, the molds are opened and the base material 21 of sheet for the decorated sheet 4 is separated whereby a plastic molded product, transferred with the picture of hologram, may be obtained.
