Abstract
A vacuum molding roll structure for molding in vacuum convex forms on the surface of a film such as a synthetic resin sheet or the like. Recesses corresponding to the convex forms are formed on the outer periphery of the roll. A vacuum passage which communicates with the recesses is formed in the roll through the width of the roll along the axial direction of the roll. A vacuum side plate which supports a roll shaft and is secured to the roll body side is provided at the side face of the roll. This side plate is formed with a groove of an adequate length extending circumferentially of the side plate at the position faced with the vacuum passage. Communicating means for communicating with a vacuum source is provided at the groove. A plane metal formed through the periphery with a hole of substantially the same area as the vacuum passage at the position faced with the vacuum passage is formed between the side face of the roll and the side plate. Only while the roll is rotated so that the groove of the side plate engages the vacuum passage of the roll and the hole in the metal, the vacuum of the vacuum source is led to the recess of the roll to attract the film wound on the roll only during this time so as to form a convex portrusion on the surface of the film.
