Abstract

PURPOSE: To enhance the durability or the like, by a method wherein a preliminary molding product of the titled sleeve formed by winding an inner surface rubber sheet, an outer surface rubber sheet or the like cylindrically around a winding jig, is subjected heat treatment at a temp. not promoting vulcanization, and then the vulcanization thereof is completed.
CONSTITUTION: In a method for preparing a flexible sleeve used in a fluid pressure apparatus such as an air spring apparatus or a shock absorber as a rolling seal material, a preceding procedure 7 and a preliminary molding procedure 8 forming a cylindrical shape by succeedingly winding an inner surface rubber sheet, two layers of reinforcing tire fabric cords mutually wound to reverse directions and an outer surface rubber sheet around a winding jig are carried out. Subsequently, the preliminarily molded article is withdrawn from the winding jig and applied to a heating core metal and, after the heat treatment 9 is carried out at a temp. of about 70W 110°C for about 30min., a vulcanization procedure 11 is carried out and, after this procedure 11 is completed, a post procedure 12 such as a surface finishing procedure is carried out to obtain the titled sleeve.
