PROBLEM TO BE SOLVED: To provide a straw member locking part molding device to which a mechanism for molding locking parts to be formed in sequentially supplied straw members is assembled in relation to the conveying of the straw members. SOLUTION: In a straw member locking part molding device, a straw member 50 is conveyed from an input drum 67 to an output drum 71 via an intermediate drum 69. Straw holding parts 68, 70, 72 are installed on the outer peripheries of the drums 67, 69, 71 at intervals to one another. A molding mechanism 74 is assembled in relation to the intermediate drum 69. While the straw member 50 is being conveyed by the intermediate drum 69, a locking part that is recessed either partly or throughout its periphery is molded in a predetermined part of the straw member 50 by thermal deformation. |
