Description of the Related Art A reel on which a metal filament such as a steel cord or a wire is wound has a winding drum portion and a flange, and a curved portion is formed on an outer edge portion of the reel to reinforce the flange. Normally, in order to lock the end portion of the metal filament that has been wound around the winding drum, the lead hole of the filament pierced in the outer peripheral portion of the flange and the flange adjacent to the lead hole are formed. The clip was provided with a clip-shaped locking member fixed to the outer peripheral edge on the outer surface. Then, the end portion of the metal wire wound around the winding drum portion is led out of the lead-out hole to the outside of the flange and is locked by a locking tool. Has been carried out in the gap of the outer edge portion of the sheet.
As described above, since the terminal portion of the metal filament exists outside the flange, it not only obstructs during transportation / storage, etc. It had to be moved to the winding drum side, and it took time and effort to unwind the wire.

[0003] When inserting a metal wire such as a steel cord into the lead-out hole, the tip of the end of the steel cord usually has many loose cases. In this case, it is necessary to correct the tip. For this reason, it is difficult to automate the guidance of the leading end of the terminal portion to the outlet hole, and there is only a manual method, resulting in a large work load.

[0004] The present applicant has proposed a new reel for a metal filament in the prior art. This is a reel that can be easily locked and unwound without passing the metal wire through the lead-out hole provided on the flange. It has become.

FIG. 7 is a sectional view of a reel for a metal wire that has been already proposed. In the drawing, 31 is a flange, and 32 is a through hole formed there. The locking device 30 includes a fixing portion 33, a grip portion 34, and a bridging portion 35 connecting the fixing portion 33 and the bridging portion 35 together with the grip portion 34 when the metal filament is locked. 34 is projected from the passage hole 32 to the inside of the flange 31, and the metal wire is sandwiched between the inner surfaces of the flange 31. That is, since the grip portion 34 of the locking member 30 is not at least on the inner surface of the flange 31 when the metal wire W is wound, the metal wire W is
It can be wound up without contacting the surface.

[0006]

However, there is still a point that the already proposed reel for metal filaments still needs to be improved. For example, a metal filament to be locked on the inner surface of the flange 31 is required. It has been pointed out that if the terminal part of the body is left as it is, the position of the tip is unstable, and it is often a problem that the tip is separated.
