め、次のような問題がある。Generally, escalator handrails have a C-shaped cross section, and their specific structure is to have a laminated main body surface made of several layers of canvas, etc., to improve the appearance or to improve the feel to the human hand. For this reason, a decorative rubber is integrally formed on the surface of the rubber, making it 4'f/7. In this case, if we look at the manufacturing process before vulcanization of this handrail, we can see that in the past, several sheets of 11111 cloth were preheated with a tension member sandwiched between the cloths, and then the cross section was A canvas laminate main body with an approximately C-shaped cross section is formed by pressure molding into a C shape, and then the canvas laminate main body and decorative rubber are simply stacked on top of each other using a vulcanizing machine, packaged, stored, and cured. When pressing with sulfur, the packaging was immediately unwrapped and placed in a mold. Therefore, the non-adhesive laminate of the canvas laminate main body and the decorative rubber is simply left alone before vulcanization, which causes the following problems.
（１）Ｃ型帆布積層本体は、周面に接着剤が塗布された
状態で保管されるだめ、塵埃等が付き易く、接着性を阻
害させる。(1) If the C-shaped canvas laminated main body is stored with adhesive applied to its circumferential surface, it is likely to attract dust and the like, which will impede the adhesion.
（２）Ｃ型帆布積層本体と化粧ゴムを重ね合わせるため
に化粧ゴムは全長広けられるため、その時、化粧ゴムが
汚される恐れがある。(2) The entire length of the decorative rubber is expanded in order to overlap the C-shaped canvas laminated body and the decorative rubber, so there is a risk that the decorative rubber may be soiled at that time.
（３）金型ヘセットする際、両者の重ね合わせが手作業
により行な、われるため、金型仕込みに時間がかかシ、

ールド後の気泡、アパタ等外観不良を発生させる恐れが
ある。(3) When setting the mold into the mold, the overlapping of the two is done manually, so it takes time to prepare the mold.
Moreover, it is necessary to replenish rubber to the ears, and there is a risk that defects in appearance such as bubbles and apatter may occur after molding.
（４ン 帆布のＣ型積層成形工程と、その工程により
接着一体化されたＣ型帆布積層主体と化粧ゴムとの重ね
合わせ工程とが別ラインで行なわれていたため、保管や
マテハン等にムダが発生し、非能率的で、ちる。(4) The C-shaped canvas lamination molding process and the process of overlapping the C-shaped canvas laminated main body and decorative rubber, which were bonded and integrated through that process, were performed on separate lines, resulting in waste in storage and material handling. Generous, inefficient, and boring.

、次工程のモールド作業において大幅な段取作業の低減
となる。There is also a method of simply crimping the C-shaped canvas laminate body and the decorative rubber with a press before vulcanization, but this requires intermittent work and is inefficient. Originally, the canvas laminated body is molded in a continuous process, so if the specified decorative rubber could also be crimped and integrated on this production line at the same time, the process would be omitted, and the setup work in the next molding process would be significantly reduced. Become.

の製造方法にある。The purpose of this invention is to eliminate the drawbacks of the prior art described above,
It is an object of the present invention to provide a method for easily manufacturing a handrail preformed before vulcanization, which can significantly streamline the process of manufacturing moving handrails. The 10th roll part, which consists of a grooved roll having a groove similar to the back surface of the main body in the center and a front roll rotating toward the grooved surface of the grooved roll, is inserted through a band-shaped unvulcanized decorative rubber. By passing the decorative rubber through it, the central part of the decorative rubber is crimped and integrated with the back part of the canvas laminated body, and both sides of the decorative rubber are made to stand almost upright in the direction perpendicular to the axial direction of the (a) Nisotrol, and later the canvas is Preforming in which both sides of the upright decorative rubber are crimped and integrated with the canvas laminate main body by passing through a 20th roll section consisting of two curved rolls each having a curved surface similar to the ears of the laminate main body. It's in the manufacturing method of handrails.

言うまでも々い。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.The working process is carried out in front of the handrail guide 1 shown in Fig. 1.First, several sheets of cotton canvas are placed between appropriate cotton canvases. A canvas laminated body 2, for example as shown in FIG. A band-shaped unvulcanized decorative rubber 3 with a slightly thick portion is prepared. Next, as will be explained based on FIG. 1, the canvas laminated body 2 is introduced into the 10th rule section A, which characterizes a part of the present invention, with the middle mold 4 disposed inside the canvas laminated body 2 using a lead wire or the like. At the same time, the band-shaped unvulcanized decorative rubber 3 is sequentially passed through the centering guide plate 6 and the rat/ξ guide 7 from the decorative rubber delivery stand 5 disposed below the canvas laminated body 2 to form the canvas laminated body 2. Nagisa on the back of 2. makeup rubber 3
Needless to say, the adhesive surface of the decorative rubber 3 is previously coated with adhesive by a solvent coating device W8, as shown in FIG. Next, when introduced into the 10th-rule part A, the 10th-rule part A forms a second concave or, as shown enlarged in FIG. Since the lower concave groove roll 9 and the flat roll 10 located above the roll 9 and which rotates toward the concave groove form a +f/i, the lower concave groove roll 9 and When introduced between the furanotrol 10 and the rolls 9 and 10, the central part of the decorative rubber 3 is bonded and integrated with the back of the canvas laminate main body 2, and both sides of the decorative rubber 3 are bonded together. is bent almost vertically in a direction perpendicular to the axial direction of the front roll 10 due to the influence of the compression on the 10th roll portion and adhesion near both side portions of the decorative rubber 30. For this reason, the canvas laminated body 2 led out from the 10th loop section A in which both sides of the decorative rubber 3 are upright is immediately introduced into the 20th loop section B; Le part B
As shown in FIG. 2 or FIG. 4, there is one lower concave roll 11 having similar, drum-shaped grooves on the back surface of the canvas laminated body 2, and grooves on both ends of the concave roll 11. '@11
C-shaped canvas laminated body 2 standing perpendicular to the direction
12.1 Two curved rolls with curved surfaces similar to the ears of
3, so those roles 11.12
and 13, the upright portion of the decorative rubber 3 is immediately pressed by these rolls, so that the decorative rubber 3 is immediately integrated by pressure bonding to the outer surface of the canvas laminate body 2, and is vulcanized. The manufacturing method of the preformed band rail is completed. In this case, both sides of the decorative rubber 3 are very thin, and since they are unvulcanized rubber, if they are crimped with a normal roll, the rubber will loosen backwards, causing wrinkles, so this phenomenon is eliminated. Therefore, it goes without saying that the circumferential speed of each roll in the 20th roll section B is adjusted to be faster as the decorative rubber 3 approaches the end in the longitudinal direction.

成してもよい。Incidentally, in one embodiment of the present invention, the 20th roll portion B is composed of three rolls, but if the upright portions on both sides of the decorative rubber 3 can be reliably integrated into both ear portions of the canvas laminated body 20, As shown in FIG. 5, it may be constructed from two pressing rolls 14 and 15 whose central portion has a curved surface similar to the entire surface of the ear portion of the main body 2.

品質の安定化がはかれる。As described above, according to the present invention, by utilizing a unique roll mechanism, the C-shaped canvas laminate main body and the decorative rubber can be bonded and integrated together smoothly, and the quality can be stabilized because they are continuously molded.
しかも帆布積層本体を形成するラインに容易に連動させ
ることができることから大幅に作業性が向上し、よって
その工業的価値は犬である。Moreover, since it can be easily linked to the line for forming the canvas laminated body, workability is greatly improved, and its industrial value is therefore significant.
