いて折り返されている。Handrails are used as movable handrails on escalators and auto lines, and their structure has a C-shaped cross section as shown in Figure 1, and the surface is covered with a decorative rubber layer.
．． The middle layer is tensile material Ir! :2. The lower layer is a sail r1pfi3 with an unvulcanized rubber sheet on the upper surface. This canvas layer 3 with an unvulcanized rubber sheet on the upper surface is folded back at the edge portion 4 as shown in FIG.

損し、加硫ビートゴム５がＪ臣び出し乗客に危害を加え
る懸念がある。Recently, in order to improve the bending characteristics of handrails, as shown in FIG. 2, a round string-shaped beat rubber 5 has been inserted. This heat rubber 5 uses vulcanized bead rubber 5 to prevent deformation during insertion into the hunt rail. Therefore, in the mold vulcanization work of the Hen 18 rail, the unvulcanized rubber sheet of the canvas layer 3 with the upper surface unvulcanized rubber sheet 41 and the vulcanized heat rubber 5 are welded together by mold vulcanization, which increases the adhesive strength. A decline is inevitable. For this reason, when the handrail is attached to an escalator or an auto line and is being operated, there is a fear that the ears of the huntrail may be damaged and the vulcanized beat rubber 5 may come out and cause harm to passengers.

作業性が悪化する難点がある。Conventionally, as a method for improving the adhesion between the unvulcanized rubber sheet of the canvas jacket 3 with an unvulcanized rubber sheet on the top surface and the vulcanized vinyl rubber 5, unvulcanized rubber glue was applied to the surface of the vulcanized vinyl rubber 5. Apply,
Methods have been used to improve the adhesion of vulcanized beet rubber 5. However, this method has the disadvantage that the unvulcanized rubber paste sticks, which deteriorates the workability of applying the unvulcanized rubber paste and inserting the σ vulcanized beet rubber 5.

することにある。The present invention has been made from this point of view, and its purpose is to eliminate the drawbacks of the prior art described above and to use beet rubber that has good mold vulcanization workability and mold vulcanization adhesion. The purpose of the present invention is to provide a method for manufacturing a handrail.

製造方法にある。The gist of the present invention is that the cross-sectional shape is C-shaped,
The surface is unvulcanized decorative rubber jg l, and the middle layer is tensile material N2.
In the method for manufacturing a handrail, the lower layer is composed of a canvas layer 3 having an upper surface of an unvulcanized rubber sheet, and a beat rubber 5 is inserted into the ear portion 4 of the canvas layer 3 having an upper surface of the unvulcanized rubber sheet, and then the beat rubber is mold-vulcanized. 5, there is a method for manufacturing a handrail characterized in that a two-layer bead rubber 20 is used in which the inner layer is a vulcanized rubber layer 21 and the outer layer is an unvulcanized rubber N22.

硫接着できる。In the method for manufacturing a handrail of the present invention, the inner layer is made of vulcanized rubber, I! ! 21. The two-layer bead rubber 2o, whose outer layer is composed of the vulcanized rubber layer 22, has no adhesiveness and is strong, so that it can be inserted into the ear portion 4 very smoothly. Furthermore, 2)-Since the surface layer of the beet rubber 20 is made of unvulcanized rubber with excellent mold vulcanization adhesion, the two-layer beet rubber 20 and the canvas layer 3 with the upper unvulcanized rubber sheet are unvulcanized by mold vulcanization. Strong mold vulcanization adhesion is possible between the rubber sheet and the rubber sheet.

る。The two-layer beet rubber 2o used in the method for manufacturing a handrail of the present invention has an inner layer of vulcanized rubber, m! 21゜The outer layer consists of an unvulcanized rubber layer 22, but the inner J- is 65%~ of the total thickness.
98% is appropriate. That is, if the inner layer is less than 65% of the total thickness, plastic deformation of the two-layer beet rubber 2o occurs during mold vulcanization, and the original reinforcing effect of the beet rubber is impaired. In addition, if the inner layer exceeds 98% of the total thickness, the outer unvulcanized rubber layer 22 becomes relatively dense, and as a result, the mold vulcanization adhesion of the two-layer beet rubber 20 is impaired.
