附近で口が開く現象が発生する欠点があった。2. Description of the Related Art Conventionally, as a material for a wire harness protector, a long strip E (FIG. 5) having a channel-shaped cross section having flanges on both edges has been manufactured and supplied. This band-shaped material is cut to a length equivalent to the outer circumference of the wire harness to be attached, and then wrapped around the wire harness.
The method of winding the tape and fixing it with the clamp metal fittings j has been used. However, when winding a straight protector material cut without bending the nose, as shown in FIG. 7, the joint opens near the flanges on both sides and the mouth opens. There was a drawback that the phenomenon occurred.

の問題が発生するようになった。As shown in FIG. 4, in the manufacturing apparatus for the protector material E (FIG. 5), the high temperature material extruded from the nozzle a is solidified into a band shape while passing through a straight water tank c containing cooling water and wound. It is taken up by the take-up machine d. When this strip-shaped material E is cut into the wire harness outer peripheral length, wound, and attached by the clamp j, as shown in FIG. 7, even if the tape h is strongly wound and pressed, i at both ends is opened and the wire harness is damaged. In addition, due to the elasticity of the strip E to return to a straight line, the tape h gradually extends to open the connection part and loosen the fixing of the wire harness, which causes a quality problem. .

A method has been adopted in which the series according to size (Fig. 6) is systematically manufactured, kept in stock, selected according to the outer diameter of the wire harness, and attached with the clamp j.

どの管理面を含めると極めて高い総合コストになる欠点
があった。The outer diameter of the wire harness varies depending on the type of wire to be manufactured, and even with the same wire harness, the diameter changes with each branch, so that molded products with an extremely large number of inner diameters can be manufactured. Since it is necessary, the management cost such as production planning, ordering, manufacturing, inventory, delivery by size, selection and use, etc., causes a very high total cost.

It is pushed out at a high temperature and a high pressure, and while being helically in contact with the outer surface of the cylindrical body in the cooling water tank installed in front of the nozzle while pulling, it is moved in the axial direction of the cylinder to lower the temperature and solidify, and then wound up. It is characterized in that it is configured to be wound up on a machine.

【実施例】以下この発明について、図面を参照して具体
的にプロテクタの製造方法を説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of manufacturing a protector according to the present invention will be specifically described below with reference to the drawings.

ったプロテクタの説明斜視図である。Here, FIG. 1 is a continuous manufacturing apparatus of a curling protector material, and FIG. 2 is an explanatory perspective view of a protector made by cutting the curling material according to the outer peripheral length of a wire harness. .
【0010】図1で、射出成形機のチャンネル形ノズル
孔をもつ射出ノズル1から押し出された高温度のプラス
チック材料2aを、冷却ノズル3から噴出する冷却水で
冷やしながら、プラスチックの押し出し方向とほぼ直角

て、カーリングのついた帯状材2cを、円筒体の側方に
ある巻き取り機軸6に帯状で巻き取り、これを切断して
プロテクタ2を形成する製造方法である。In FIG. 1, while cooling the high-temperature plastic material 2a extruded from the injection nozzle 1 having the channel-shaped nozzle holes of the injection molding machine with the cooling water ejected from the cooling nozzle 3, the direction of extrusion of the plastic is almost the same. While being in contact with the cooled outer peripheral surface 4a of the cylindrical body 5 provided in the cooling water tank 4 at a right angle, it is spirally pulled toward the winder side to be cooled, and with a curvature equivalent to the outer diameter dimension of the cylindrical body. This is a manufacturing method in which the belt-shaped material 2c, which is solidified and curled, is wound around the winder shaft 6 on the side of the cylindrical body in a belt-like shape and cut to form the protector 2.
【0011】この製造装置で製造されたプロテクタ帯状
材2cの固有曲率半径rは、円筒体5の円半径rとほぼ
同等の曲率にカーリングしているので、この曲率半径よ

切断したプロテクタ(図2)は、カーリングによって半
径rにまるくなり、両端2e部も半径rに鼻曲げされる
ようになる。Since the protector strip 2c manufactured by this manufacturing apparatus is curled to have a curvature radius r substantially equal to the circular radius r of the cylindrical body 5, the outer circumference of the wire harness is slightly larger than this curvature radius. The protector (FIG. 2) cut in accordance with the length dimension is rounded to a radius r by curling, and both ends 2e are also bent to the radius r.
【0012】このカーリングしたプロテクタ2の口を開

曲げされているために接続部も密着して、高密着のプロ
テクタとなり、図7のような口開き現象iは全く発生し
ない。When the curled protector 2 is opened and attached to the wire harness, the curl protects the wire harness and hugs the wire harness firmly. Moreover, since the nose is bent, the connection portion also comes into close contact with the protector. Therefore, the mouth opening phenomenon i as shown in FIG. 7 does not occur at all.

出来るために、生産に於いては、段階的に少ない外径寸
法の円筒体5を準備すれば十分である。In the protector 2 manufactured by this method, even if the outer diameter of the wire harness changes to a certain extent, the curling force of the protector 2 bites the outer circumference of the wire harness. Since it is possible to cope with a change in the outer diameter of the wire harness to a considerable extent by changing the above, it is sufficient in production to prepare the cylindrical body 5 having the outer diameter gradually reduced.
【0014】なお、図1に示す円筒体5は、図3に示す

もよい。The cylindrical body 5 shown in FIG. 1 may use a grooved cylindrical body 7 having a spiral groove 7a as shown in FIG.

設けても作用は同様である。Also, instead of the spiral grooved cylindrical body 7, a spiral guide cover (not shown) may be provided on the outside of the grooveless cylindrical body 5 to obtain the same operation.

大幅に低減される。As described above, the wire harness protector produced by the protector material manufacturing apparatus of the present invention has a high quality protector performance because it is bitten and closely adhered to the wire harness by curling, and also has a common size. Since the width is wide, it is possible to support a wide variety of products, which reduces the manufacturing cost. Since all you have to do is prepare the materials, various management costs for all processes such as manufacturing, inventory, and assembly will be greatly reduced.
