Elastic sleeve for shoe press, method of manufacturing the elastic sleeve for shoe press, and shoe press roll

摘要

A method of manufacturing an elastic sleeve for a shoe press having an inner diameter gradually reduced from both ends toward a center in an axial direction, comprising the steps of stretching the sleeve formed of an uncured or imperfectly cured elastic material between two rolls, moving the two rolls in directions apart from each other while deflecting the two rolls in such directions that the center parts thereof are moved close to each other by utilizing the tension of the sleeve, and perfectly curing, in this state, the elastic material while rotating the sleeve to gradually reduce the inner diameter of the elastic sleeve from both ends toward the center in the axial direction.
