ABSTRACT:
A rubberized roll for the sealing device of a high-pressure apparatus comprises a shell with pins provided at both ends thereof and protruding with their enlarged portion thereinside, thus defining the shell interior. One of the pins is provided with a through axial duct for a cooling agent to feed into the shell interior while the other pin has a similar duct only in its enlarged portion. Provided at the ends of the enlarged portions are collars forming an annular cavity in each of said enlarged portions, said annular cavity being connected to the axial duct of the respective enlarged portion and to the shell interior. An annular groove for retaining the rubberizing material therein is cut in the outer end face of the collar located at the outer ends of each enlarged portion of the pin. Such a construction of the roller provides for a uniform cooling of the surface thereof and contributes to a reliable adhesion of the rubberizing material to the roll end faces.
