    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a handrail, capable of manufacturing the handrail integrally by making an extruding speed of an extruder for an outer material constant and by manufacturing a synthetic resin handrail member separately from a metallic pipe and then inserting the metallic pipe into the handrail member.SOLUTION: A base resin material is extruded by a first extruder 15 and is cooled so as to mold a base pipe 2. The base pipe 2 is taken off at a constant speed by a first take-off machine 13 and the base pipe 2 is taken off by a second take-off machine 14. At the same time, the base pipe 2 is pushed to a second extruder 15 and by adjusting a take-off speed of the second take-off machine 14 while an outer resin material is extruded from the second extruder 15 onto an outer peripheral face of the base pipe 2 at a constant speed, an outer pipe 3 in which swelling parts 7 are formed at intervals in a length direction of the base pipe 2 is extruded and cooled, so as to be molded integrally with the base pipe 2. A handrail member 4 having a double pipe structure consisting of the base pipe 2 and the outer pipe 3 is taken off by a third take-off machine 17 at a constant speed.
    • 要解决的问题:提供一种制造扶手的方法,其能够通过使外部材料的挤出机的挤出速度一致地制造扶手,并且通过与金属管分开制造合成树脂扶手构件,然后将 将金属管插入扶手构件中。解决方案:基础树脂材料由第一挤出机15挤出并冷却以使基管2成型。基管2通过第一取料机以恒定速度取出 13,基管2由第二送出机14取出。同时,将基管2推入第二挤出机15,并通过调节第二出料机14的取出速度 同时外部树脂材料从第二挤出机15以恒定速度挤出到基管2的外周面上,在基管2的长度方向间隔地形成有膨胀部7的外管3是 挤压和 冷却,以便与基管2一体模制。具有由基管2和外管3组成的双管结构的扶手构件4以恒定的速度被第三送出机17取出。

    • PROBLEM TO BE SOLVED: To provide a resin cylindrical body which has various uneven designs on an outer peripheral face thereof, is suitable for a cover of a pipe for a handrail and can be manufactured inexpensively.SOLUTION: A resin cylindrical body 1 includes: a body 11 of the cylindrical body formed to have a cylindrical shape by fitting a nozzle 23a into a die 23 of an extruder 2 and extruding resin; and an uneven design 12 formed on an outer peripheral face of the body 11 of the cylindrical body. The uneven design 12 is formed by pressing an uneven pattern 33 which is formed on a roll outer peripheral face of a roll 3 rotated in the same direction as a direction in which the body 11 of the cylindrical body is extruded against the outer peripheral face of the body 11 of the cylindrical body.
    • 要解决的问题:为了提供在其外周面上具有各种不均匀设计的树脂圆筒体,适用于扶手用管的盖,并且可以廉价地制造。解决方案:树脂圆筒体1包括: 通过将喷嘴23a装配到挤出机2的模具23和挤出树脂中而形成为圆筒形状的本体11; 以及形成在圆筒体的主体11的外周面上的不平坦的设计12。 凹凸图案12是通过挤压形成在辊筒3的辊外周面上的不均匀图案33而形成的,该卷筒3沿与筒状体11的主体11挤压的方向相同的方向旋转, 圆柱体的主体11。
