摘要:
Method for forming and vulcanizing a hose (1), inner former (4) used in said method, and hose (1) obtained by means of said method. In the method of the invention an expandable inner former (4) is used and which is inserted in the unvulcanized hose (1), the unit formed by the inner former (4) and the unvulcanized hose (1) being housed in an internal cavity (3) formed by an external mould for its subsequent forming and vulcanization. The method comprises, prior to the insertion of the unit formed by the inner former (4) and the unvulcanized hose (1), a first stage in which the inner former (4) is arranged substantially straight, a second stage in which said inner former (4) is inserted in the unvulcanized hose (1), and a third stage in which the inner former (4) recovers its initial shape.
