PROBLEM TO BE SOLVED: To provide an internally pressing lid in which wires such as welding electrodes are passed through a contracted mouth of a longitudinal paper drum for accommodating the wires, and always and reliably brought into contact with a wall surface of an inside diameter causing the dimensional tolerance, and smoothly suspended therefrom so that the welding electrodes can be continuously pulled out. SOLUTION: A plurality of blocks of deformed horseshoe shape in a radially curved shape at substantially equal intervals in the flat circumference by providing a plurality of ribs formed of a flexible resin strip plate used for a screen at an angle of inclination from the center are integrally arranged in a circumference. By the deflection in the horizontal direction by a rib stock, or by providing a flexible bent part on the straight horseshoe like rib, a pressing lid capable of expanding/contracting the outside diameter is formed. The lid is formed drawable upwardly from the inside of the block while rotating horizontally in the reverse-winding direction of the wire. Alternatively, the wire can be drawn from a center opening part and formed in a nonrotatable manner. |
