Furthermore, there are rubber-covered rollers in which fluororubber latex is provided on a silicone rubber layer (hereinafter referred to as FS rollers), and rollers in which fluororesin is provided in the fluororubber layer (hereinafter referred to as FF rollers).

である。By the way, as shown in Fig. 5, such a rubber-coated roller is made by coating a rubber material on a core metal that has been surface-treated and coated with a primer, crosslinking it, and then grinding it to a thickness of several tens of micrometers.
It is manufactured by forming a rubber film of ~100 mm. Furthermore, in the case of an FS roller or an FF roller having an outer layer, fluororubber latex, fluororesin, or the like is painted (coated) on the ground rubber pattern and baked to harden. Here, the coating crosslinking process varies depending on the rubber material used, and there are methods such as casting curing, electrostatic powder coating, spray coating, and dip coating.
The most common method for forming a rubber film under m is the latter method.
［発明が解決しようとする課題］
ところでこのような従来ゴム被覆ローラの製造方法は以
下に述べるような欠点がある。すなわち。[Problems to be Solved by the Invention] However, such conventional methods for manufacturing rubber-coated rollers have the following drawbacks. Namely.
吹き付塗装法の場合は材料のロスが多く、又、均一な膜

りを必要とし生産性が悪いなどの問題点がある。形成さ
れる膜に気泡が入り易く、特にゴム膜がローラ最外層で
ある場合は気泡によるピンホールはそのまま画質の低下
を招く。In the case of spray painting, there is a lot of material loss, and in order to form a uniform film, the amount of coating must be several micrometers at a time, and in order to form a thick film of several tens of micrometers or more, it is necessary to apply multiple coats. There are problems such as the need for coating and poor productivity. Air bubbles are likely to enter the formed film, and especially when the rubber film is the outermost layer of the roller, pinholes caused by the air bubbles directly cause deterioration in image quality.
このような気泡は、静電塗装の場合も同様に生じやすい
。Such bubbles are also likely to occur in electrostatic coating.
一方、浸漬塗装法の場合には、芯金をゴム材料の入った
容器に浸漬して被覆するため、膜厚をコントロールし、
又、均一な膜厚とすることが困難である。On the other hand, in the case of the dip coating method, the core metal is dipped into a container containing rubber material to coat it, so the film thickness can be controlled.
Furthermore, it is difficult to obtain a uniform film thickness.
本発明はこのような従来の難点を解消するためになされ
たもので材料のロスがなく、しがも膜厚の均一性その他
性能のすぐれたゴム膜を形成することのできるゴム被覆
ローラの製造方法を提供することを目的とする。The present invention has been made to solve these conventional problems, and it is an object of the present invention to manufacture a rubber-coated roller that can form a rubber film with uniform thickness and other excellent performance without material loss. The purpose is to provide a method.

のである。[Means for Solving the Problems] A method for manufacturing a rubber-coated roller of the present invention that achieves such an object is a method for manufacturing a rubber-coated roller by coating a rubber material on the outside of the roller and then curing the rubber material. While holding the roller horizontally, a blade is arranged so that it faces the roller and has a predetermined gap between its tip and the outer periphery of the roller, and simultaneously supplies the rubber material between the blade and the roller. The rubber material is applied to the outer periphery of the roller by rotating the roller, and after the rubber material is further applied to the outer periphery of the roller, the blade is moved back from the roller to further rotate the roller. This is to make the thickness of the rubber material applied to the surface uniform.
［作用］

の跡が消え、均一な膜厚とすることができる。[Operation] By rotating the roller without supplying the rubber material between the roller and the blade, the rubber material is coated on the outer periphery of the roller with a film thickness determined by the gap between the roller and the blade. Here, it is only necessary to supply the rubber material in an amount approximately equal to the amount required for the rubber film to be formed. By idling the roller after coating, the thickness of the coating film on the outer periphery of the roller is made uniform, the marks of the blade disappear, and a uniform coating thickness can be achieved.
この後、塗布された塗膜を熱硬化させる。After this, the applied coating film is thermally cured.
