る問題もある。Conventionally, escalators and automatic line rails are made of a rubber material on the surface side that comes in direct contact with the passenger's hands, and the back side is made of cotton canvas, etc. However, in the escalator drive part, the surface rubber layer is made of a-lar material. Due to the shift to a drive system in which pressure is applied by the upper and lower pressure rollers, the feeding friction due to the upper and lower pressure rollers is increased compared to the conventional method, and the friction between the rollers and the surface rubber layer causes a problem in that the luster of the rubber surface decreases. Factors that can reduce the luster of the surface rubber layer include dirt from passengers' palms, oil and dust in the air, gum and receipts stuck to the rubber due to mischief by passengers, and detergents, cleaners, and solvents other than those specified by the handrail manufacturer. The use of These stains penetrate and stick to the rubber, making them difficult to remove by general cleaning work, and the luster of the surface rubber cannot be restored using cleaning agents, solvents, etc. other than those specified. There is also the problem that cracks occur in the surface rubber layer during use.

合成樹脂膜を形成する場合は以下のような欠点がある。Solutions to these problems include periodic cleaning using a cleaner specified by the handrail manufacturer, and forming a synthetic resin film such as urethane on the outer surface of the decorative rubber layer. However, periodic cleaning has the drawback of consuming a lot of time and effort, and when a synthetic resin film such as urethane is formed on the outer surface of the rubber layer, there are the following drawbacks.

Moreover, if the thickness of this synthetic resin coating is large, fatal cracks will occur due to co-cracking, and if the coating is short, the life span will be 1 to 2 years.
(2) コーティングの際の刷毛、布などの塗りすじ

Prepare the one in the state where it is placed. At the same time, a band-shaped unvulcanized decorative rubber body 4 is prepared by applying and drying a synthetic resin film 6 made of urethane paint on the surface. In this case, it goes without saying that the cotton canvas 1 and the unvulcanized decorative rubber body 4 constitute a handrail preform that is part of the present invention. Next, when the preparation of the preform is completed, a synthetic resin film 6 is placed on the lower mold 5 shown in FIG.
The unvulcanized decorative rubber 4 is placed with its side facing down, the laminated cotton canvas 1 in which the tensile material 2 is embedded is laminated thereon, and the middle mold 6 and the upper mold 7 are further placed. After successively overlapping, the lower mold 5 and the upper mold 7 are heated and pressurized (vulcanized) for a certain period of time, thereby completing the molding of the handrail. In this case, during vulcanization, the synthetic resin film 6 applied to the surface of the decorative rubber 40 is softened by the heat of vulcanization, in other words, the coating is softened, and at the same time as the coating is softened, the coating lines are pressed by pressure. and is formed in a smooth direction that is approximately equal to the inner circumferential surface of each mold (in this case, each mold has a smooth surface plated with chrome).

効果をもたらしているものと考えられる。Next, a handrail with a width of 25 mm and a length of 250 mm from the flat (central) part of the handrail formed by this method, and a synthetic resin film coated after vulcanization (after handrail molding) (conventional) Handrails (depending on the method) were prepared, and strips of 25 mm in width and 250 mm in length were cut out from their flat parts (center parts) as samples, and the bending test conditions were as follows: A
According to STMD430-73, as shown in Figure 3, ψ
Apply a load of 45 kg to pulley 8 of 32, and stroke 7
When a Scott bending test was conducted with the number of reciprocations at 0 mm + 170 times/min and with the synthetic resin film 3 on the upper side,
In the case of the conventional method, cracks occurred after 7×10' bending, but in the case of the method of the present invention, no cracks occurred even after bending 2.5×10 seconds or more. Regarding this crack, according to the manufacturing method of the present invention, the synthetic resin film 3 is pressed against the rubber layer 4 by heating and pressure during vulcanization, and the crack resistance is affected because the synthetic resin film 3 acts as if it were baked or baked. It is thought that this has an even greater effect.

側のゴム層は化粧ゴム層4に限られるものではない。In one embodiment of the present invention, five layers of cotton canvas are temporarily bonded and placed in advance, and then set in a vulcanization mold. may be individually set in the mold. Moreover, in this embodiment, in order to make the most of the decorative rubber layer 4, a synthetic resin film 6 that is transparent or has approximately the same color as the decorative rubber layer 4 is formed on the rubber layer, but the synthetic resin film 6 itself is If it has cosmetic properties, will a film 6 be formed? The side rubber layer is not limited to the decorative rubber layer 4.

あり、その工業的価値は大である。As described above, according to the present invention, since the film is formed on the rubber layer before vulcanization, it is possible to easily obtain a film having a uniform surface thickness. The coating lines formed on the film surface before vulcanization disappear after vulcanization. Vulcanization has the effect of strengthening the adhesion between the rubber layer and the film, increasing the flex life, and has great industrial value.
