PROBLEM TO BE SOLVED: To provide a tape winding device of a mold in which a mold set of two matrix molds is made into a shape in which a material filling gap is parallel or inclined, and a general lens for glasses or a lens with prism prescription is obtained, in molding of a plastic lens for the glasses. SOLUTION: A cylindrical mold holder 18 in which two matrix molds 19 are opposedly set in parallel or so that one side may be slanted, is sideways mounted on a fixed cradle 10 of a machine body intermediate. The mold in the mold holder is attracted and supported with an attraction unit 1 which has attraction bodies 3 and several reversible fixed shafts 4 in a pair of leading edges arranged in both sides, and an oscillating type attraction unit 5A. An adhesive tape 27 for unreeling by cutting from a tape unreeling device 12 arranged in a lateral direction of the machine body, is wound around a circumference of the mold which is opposedly parallel or one side of which is slanted, and remains after predetermined unsetting of the holder.
