関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a spacer for an optical fiber cable, and more particularly to a method for winding a spacer for an optical fiber cable without deformation or twisting of a rib due to engagement of the spacers.

程においてスペーサの溝に光ファイバが収納される。2. Description of the Related Art Conventionally, a spacer for an optical fiber cable mainly formed of polyethylene (PE) is wound around a bobbin comprising a cylindrical winding body and flanges fixed to both ends after rotary extrusion molding. After the process, the optical fiber cable is supplied to the manufacturing process of the optical fiber cable, and the optical fiber is housed in the groove of the spacer in the process of assembling the optical fiber.

列巻きが推奨されている。In the winding step, when the spacers intersect with each other, the ribs are likely to be deformed. The deformation of the ribs causes abnormal assembly in the optical fiber assembling step and a decrease in the optical transmission performance of an optical fiber cable as a final product. Therefore, a winding method in which adjacent spacers do not intersect, so-called aligned winding is recommended.

り、光ファイバを収納するＰＥスペーサに関しても細径
化の要求が厳しくなってきている。[0005] Recently, in order to reduce the price and installation cost of optical fiber cables, studies have been made on reducing the diameter and weight of the cables and increasing the density of optical (fiber) fibers. Demands for reducing the diameter of spacers have also become severe.
【０００６】一方、最近の架空光ファイバケーブルに

反転状に設けられたＳＺ型ＰＥスペーサを使用しかつ、

ァイバケーブルが多く使用されてきている。On the other hand, recent overhead optical fiber cables are required to have an intermediate branching performance of optical fibers in addition to increasing the optical density. Using a mold PE spacer,
An SZ type optical fiber cable in which a plurality of tape-shaped optical fibers are accommodated in each groove has been widely used.

溝の撚り方向が切り変わるいわゆる反転部において噛み
合いが生じやすく、細径化によりその傾向は顕著にな
る。As described above, when the diameter of the spacer is reduced, the dimensions of the optical fiber housing groove do not change, so that the thickness of the rib defining the housing groove becomes thinner. As a result, the rib of the adjacent spacer becomes the groove of the adjacent spacer. The so-called meshing that easily enters is likely to occur. In the case of the SZ type spacer,
Engagement is apt to occur at a so-called reversal part where the twist direction of the groove changes, and the tendency becomes remarkable as the diameter is reduced.

ーサに捻れが入ったりする問題があった。Here, for example, if the spacer being wound up meshes with an adjacent spacer wound up in the front circumference, the ribs are deformed as described above, or the spacer is moved in the front circumference. There was a problem that the winding was disturbed by riding on the vehicle and the spacer was twisted.

が生じるという問題があった。Furthermore, in the case of aligned winding, the second and subsequent layers are:
It takes up the shape of the lower layer winding while winding it up along the valley, but in the case of the SZ type spacer, the lower layer winding meshes with the lower layer winding spacer, and the winding spacer oscillates to take up the winding position. However, there has been a problem that the spacer is displaced and the spacer is twisted.

おいては、巻き取り中のスペーサと既に巻き取った下層

干渉の問題があった。That is, in the SZ type spacer having a reduced diameter, there is a problem of two interferences between the spacer being wound up, the lower layer spacer already wound up, and the front spacer in the same layer.

いは防止できていなかった。The problem of meshing with the lower spacer can be solved by inserting kraft paper having a thickness of about 0.1 mm between the winding layers in order to prevent this problem. Engagement with the spacer next to the layer could not be prevented.

動が生じ、巻き崩れが発生する恐れがあった。Here, if winding is performed while leaving a slight gap between the adjacent spacer, that is, the front spacer already wound on the drum, meshing with them can be prevented, which is also described above. As described above, the spacer is moved by the vibration or the like, and there is a possibility that the winding collapse occurs.

装される。The bobbin B has a cylindrical winding drum C and a pair of disc-shaped flanges D provided at both ends of the winding drum C. Spacer A rotates bobbin B while rotating
Further, it is wound around the outer periphery of the winding drum C in a multilayer shape while being traversed along the axial direction of the winding drum C. At this time,
An interlayer material E is interposed between the surface of the winding drum section C and the layer before the winding.

A sheet-shaped material having a cushioning property and flexibility of not more than 3 cm3, for example, a thermoplastic resin foam sheet, a piece of paper cardboard-like sheet in which a corrugated core is attached to one side of liner paper, a relatively thin liner, Examples include a paper cardboard sheet made of a corrugated core or a plastic cardboard sheet having a two-layer cross-sectional structure.

にする。Since the interlayer material E needs to be fitted to the outer periphery of the winding drum or the layer after winding, it is required to have flexibility in the rotating direction, that is, the circumferential direction. When a sheet is used, the running direction of the groove of the corrugated core is set to be parallel to the width direction of the winding drum.

3を超えると層間材Ｅの占有率が高くなってスペーサの
巻き効率が低下する。When the thickness of the interlayer material E is less than 0.4 mm, the degree of deformation due to winding tension is small, the spacer after winding cannot be fixed, and the apparent density is 0.3 g / cm.
If it exceeds 3 , the occupancy of the interlayer material E increases, and the winding efficiency of the spacer decreases.

材料との間で摩擦力が働くものが望ましく、滑り易い、
即ち摩擦係数の低い材料は、巻取り時及び巻取り後のス
ペーサＡの巻状態の安定性において好ましくない。It is desirable that the interlayer material E exerts a frictional force with the material constituting the spacer A, so that it is easy to slip.
That is, a material having a low friction coefficient is not preferable in terms of stability of the winding state of the spacer A during and after winding.

Note that the interlayer material may be divided and inserted in the width direction or the circumferential direction without being entirely inserted.

る。According to the method of winding a spacer for an optical fiber cable of the present invention, an interlayer material having a cushioning property is used for the surface layer of the bobbin winding cylinder or the wound-up front layer. Is difficult to move and the winding position is fixed, so that the spacer being wound does not interfere with the previous winding layer or the previous spacer wound immediately before in the same layer. Winding can be easily and efficiently performed without causing troubles such as deformation of the spacer, twisting of the spacer body, and reverse running of the winding.
