（発明の技術分野）本発明は逆クラウンローラの製造方
法に関する。TECHNICAL FIELD OF THE INVENTION The present invention relates to a method of manufacturing an inverted crown roller.
（発明の技術的背景及びその問題点）
従来、逆クラウン形状のローラを製造するのに、砥石ロ
ーラを被研磨ローラ中心軸を平行に動かしながら、かつ
、同時にローラ径方向に砥石を動かさなければならなか
った。そのため加工工程、加工装置の構成が複雑になり
研磨精度もそれだけ落ちるものである。さらにはこうし
た複雑さが、コストアップにもつながるという欠点を有
していた。(Technical background of the invention and its problems) Conventionally, in order to manufacture an inverted crown-shaped roller, it was necessary to move the grindstone roller parallel to the center axis of the roller to be polished and at the same time move the grindstone in the radial direction of the roller. did not become. As a result, the machining process and the configuration of the machining equipment become complicated, and the polishing accuracy deteriorates accordingly. Furthermore, this complexity has the disadvantage of increasing costs.
（発明の目的）
本発明は上記の欠点を除去するためになされたもので無
研削タイプでしかもコスト低減を図った逆クラウンロー
ラの製造方法を提供することを目的とする。(Object of the Invention) The present invention was made in order to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a method for manufacturing an inverted crown roller that does not require grinding and is cost-reduced.

型することを特徴としている。(Summary of the Invention) The present invention is a method for manufacturing an inverted crown roller in which a drum-shaped rubber coating is molded on a mandrel so that the outer diameter increases continuously from the center in the axial direction toward both ends. The liquid rubber and mandrel are inserted into a cylindrical case whose outer diameter increases continuously from the center in the longitudinal direction toward both ends, and are released from the mold after hardening.

温度上昇が遅くなる０したがってゴム厚は中心部が薄く
両端部が厚くなり、硬化後離型することにより本発明の
逆クラウンローラが容易に製造できる。(Embodiments of the Invention) The present invention will be described in detail below with reference to the drawings.As shown in Fig. 0, the cylindrical shape is open at both ends and has a uniform inner diameter, and the outer diameter increases from the center in the longitudinal direction toward both ends. A lower cap 2 aligned with the drum-shaped case 1 is attached to the bottom of the case. Next, a predetermined amount of liquid rubber 3 is injected and the mandrel 4 is set. Liquid rubber may be injected after the mandrel is set. This liquid rubber is heated and cured by a well-known means (not shown), but in this case, since the center of the case 1 is thin and the ends are thick, the temperature rises quickly at the center and slows at both ends. The rubber is thinner at the center and thicker at both ends, and by releasing the rubber after curing, the inverted crown roller of the present invention can be easily produced.
（発明の効果）
以上述べたように本発明の逆クラウンローラの製造方法
によれば、研削工程を必要とせず生産性が大幅に向上す
るという効果が得られる。(Effects of the Invention) As described above, according to the method for manufacturing an inverted crown roller of the present invention, it is possible to obtain the effect that a grinding process is not required and productivity is significantly improved.
