９の大きさの形状が好ましいのである。That is, the size of the uneven portions 8a, 8b and the uneven portion 9 is 1μ.
If it is less than 15 μm, the contact area becomes large, so there is a problem that the unwinding property of the rubber plate W is poor as in the past, and that they stick together when stacked. becomes too small, causing problems with the product. Therefore, it is preferable that the concavo-convex portions 8a, 8b and the concavo-convex portion 9 have the above-mentioned size ranges.

の表面に凹凸部９を形成するのである。When continuously vulcanizing, for example, unvulcanized rubber FiW using the continuous vulcanizing device as described above, the unvulcanized rubber plate W is placed between the main roll 1 and the first pressure roll 2. into the vulcanization area X while pressing the top surface with the steel belt S.
The rubber plate W in an unvulcanized state is continuously vulcanized by passing through the rubber plate W. At this time, the uneven parts 8a and 8b formed on at least one of the surface of the main roll 10 or the surface of the steel belt S cause the rubber plate W to
The uneven portion 9 is formed on the surface.
