Description
【発明の詳細な説明】 (発明の技術分野) 不発明にローラの製造方法に係る。[Detailed description of the invention] (Technical field of invention) The invention relates to a method of manufacturing a roller.
(発明の技術的背景およびその問題点)例えば複写機の

ゴム層を被覆して構成されている。(Technical Background of the Invention and Problems Thereof) For example, the pressure roller of a copying machine has a foamable rubber layer such as silicone rubber on the outer periphery of a metal roller core shaft, and the outer periphery is further covered with a non-foamable rubber layer. It is configured as follows.
従来上記のようなローラを製造するには、金型内に芯金

多かつ几。Conventionally, in order to manufacture the above-mentioned rollers, a core metal tube is inserted into a mold and a foamed rubber layer is formed by heating the foamed resin for 20 seconds to 1 hour in the air or vacuum. Place the rubber roller in the mold and press in air or vacuum.
A casting method in which non-foaming resin is injected is used.This casting method often causes air bubbles to enter the non-foaming rubber layer, resulting in defects.
又ただ単に非発泡性ゴム槽に浸漬して非発泡性ゴム層を

う欠点全有していた。Furthermore, the method of simply immersing the sponge in a non-foaming rubber bath to form a non-foaming rubber layer also has the disadvantage that air bubbles may enter the non-foaming sponge layer.
(発明の目的)

ものである。(Objective of the Invention) The invention was made in view of the above circumstances, and provides a method for manufacturing a roller that prevents air bubbles from forming between the foamable rubber layer and the non-foamable rubber layer during the formation of the non-foamable rubber layer. This is what we are trying to provide.
(発明のi表)

よシ前記目的を達成している。(Table i of the invention) "Non-expanding" is a method for manufacturing a roller in which a foamable rubber layer is formed on the outer periphery of a core shaft, and then a non-foaming rubber layer is entirely formed on this outer periphery. The layer achieves this objective by being formed entirely of thin layers of uncured, non-foamed rubber.
不発明の発泡性ゴム層は常法により形成されるが、この
発泡性ゴム層の外周に形成される非発泡性ゴム層は形成

あり、前記樹脂が硬化する前に非発泡性ゴム層を設ける
。The non-inventive foamable rubber layer is formed by a conventional method, but the non-foamable rubber layer formed around the outer periphery of the foamable rubber layer requires the interposition of an uncured non-foamable thin layer during formation. Yes, and a non-foaming rubber layer is provided before the resin is cured.
(発明の実施例) 以下不発明の詳細な説明する。(Example of the invention) The non-invention will be explained in detail below.
まず、金属円筒外型に非発泡性ゴムを注型し樹脂内型を

却し、外型よジ離型しチューブ會作成する。First, a non-foaming rubber is poured into a metal cylindrical outer mold, a resin inner mold is inserted, and the resin is cured. After that, it is cooled at a temperature lower than room temperature and released from the outer mold to form a tube.
一万、芯軸と発泡性ゴム層;n り成るスポンジローラ
表面に非発泡性ゴムを塗布し、前記非発泡性ゴムが硬化

して発泡層と非発泡層を一体化させる。10,000, non-foaming rubber is applied to the surface of the sponge roller consisting of a core shaft and a foamable rubber layer; the tube is covered before the non-foaming rubber hardens, and then the foam is formed by heating it at room temperature. The layer and the non-foamed layer are integrated.

布しても同様の効果が得られる。According to this method, no air bubbles enter the non-foamable rubber layer, and the non-foamable rubber lying on the surface of the sponge roller improves the adhesiveness between the foamable rubber layer and the non-foamable rubber layer. A similar effect can be obtained by applying uncured non-foaming rubber to the inside of a non-foaming rubber tube.

成することもできる。In addition, as another embodiment of the present invention, a core shaft and a foamed rubber layer! JIy, by applying uncured non-foaming rubber to the surface of the sponge roller to remove all air bubbles on the surface of the sponge roll, then immersing the roller in a bath containing the non-foaming rubber, and then heating it at room temperature or heating. A non-foaming rubber layer can also be formed.

でよく切削刃ロエ會必要としない。With this method, there are no air bubbles in the non-foaming rubber layer, and since no molds are used, there is less loss of material, and the required thickness of the covering syllable can be obtained, so the finishing process requires only polishing and cutting. Blade loe meeting not required.
