When the internal pressure of the space 21 and the material press-in pressure P 2 are balanced, the core shaft 1 and the cap 60 descend due to their own weight, and the tapered surface 51 of the cap 50 fitted to the lower part of the core shaft 1 becomes as shown in FIG. As shown, it is pressed against the tapered surface 41 of the lower plug body 40 and comes into close contact with it, and operates like a check valve against the press-fitted material. Therefore, the inner pressure in the space 21 is maintained under pressure until the rubber or plastic material hardens, and after hardening, the core shaft 1 is pulled out from the cylindrical mold 30 to produce the rubber or plastic coated roller of the present invention. Ru. The rubber/plastic layer 2 thus obtained has no discernible pinholes or pores, and furthermore, the upper stopper 70
By providing an air vent hole in at least one of the tapered surfaces 71, 61 of the cap 60, some burrs are generated on the end face of the roller core shaft, but since these burrs are string-like, they are easy to remove and melt, and the end face No special secondary processing is required.

[Effects of the Invention] According to the method of manufacturing a rubber or plastic coated roller of the present invention, the molding device is provided with a mechanism such as a check valve with a simple structure, so that the loss rubber removal operation after the rubber roller is released from the mold becomes easy. . Furthermore, since it has a mechanism such as a check valve, there is no occurrence of liquid leakage during case transfer, and intermittent continuous injection is possible.
Further, it is possible to easily produce a roller that satisfies the required performance as a rubber or plastic coated roller for various uses without requiring any particular secondary processing. Furthermore, since the manufactured roller does not have pinballs, holes, etc., it will not cause uneven contact or clogging with foreign matter when it comes into pressure contact with other rollers in use.
