Abstract: A compression molding device, which can obtain a high compression molding force without lowering the efficiency of article production, and whose molding means has a long service life, is provided. In the compression molding device, a one-side mold assembly moving means (58) includes a toggle link mechanism including two links (62) and (64), and a toggle link mechanism operating means (60), while an opposite-side mold assembly moving means (108) includes a hydraulic cylinder mechanism. When a one-side mold assembly (16) and an opposite-side mold assembly (18) are to be brought from an open state into a closed state, the one-side mold assembly (16) is first moved to a nearly closed state by the one-side mold assembly moving means (58), and then the opposite-side mold assembly (18) is moved from the nearly closed state to the closed state by the opposite-side mold assembly moving means (108).

Abstract: A method of inspecting a wrap-fitted state of a cap that is wrap-fitted to the neck of a bottle by detecting a positional relationship between a bottle mark and a cap mark, wherein an optical lens is arranged at a higher position on the vertical center axis of the bottle to which the cap is wrap-fitted, a single camera is arranged at a higher position on the optical axis of the optical lens to image the bottle mark and the cap mark through the optical lens, an illumination device is arranged for illuminating the bottle mark and the cap mark, the bottle mark and the cap mark are simultaneously shot by the camera, and the obtained image is sent to an image processor to detect a positional relationship between the bottle mark and the cap mark.
