する、。Methods for manufacturing this type of rubber roll include method 1 in which the rubber roll is coated with a nylon sleeve, and a method in which nylon powder is applied to the surface of the comb roll and then heated and welded. Not only is it difficult to make close contact between the main body and the sleeve, but also there is a problem with the mechanical strength of nylon. I can't make rolls. The latter has a problem in the heat resistance of the rubber roll, and has the disadvantage that other parts are limited to the use of nylon powder. In addition, it has drawbacks such as weak adhesion between the main body and the nylon sleeve.

This is supported and sealed in the holding mold 7 consisting of the upper and lower molds of the cylindrical mold 1, and the roll shaft 5. Unvulcanized rubber is poured into the cavity 8 formed by the support split mold 6 and the nylon coating 3, and the roll main body 9 is cured and aged (165° C., 20 uin), and the roll main body 91 is cured with the nylon coating 8. A rubber roll 10 (inner diameter JJffL length 250+1ff), which was molded into one piece by transfer bonding and having a surface fc nylon coating, was taken out from the mold. Coating of nylon powder is carried out by means such as powder electrostatic coating and fluidized dipping. In the figure, 78 is an injection hole, and 7b is a runner.
