The cam is eccentric by being connected to a ball joint portion(12). The heat adhering portion is cut by a cutting blade(10) fixed to a cutting frame(7) of the cam holder moving back and forth with the cam and spring(8b). A support frame(18) approaches the heat adhering portion of the packing gas with shaking up and down in the curve track by a cam holder(17) contacting a cam(16).
