Abstract

Method for press vulcanizing, not only of dry, wholly or partly vulcanizable articles (1), such as auto rubber mats, piled rubber mats, etc., of a humidity of 0-3 weight percent but also of such articles (1) of a humidity of 3-5 weight percent or more, in the press zone of a vulcanizing press (P) having a shiftable part for closing and opening of the press (P) capable of applying a uniform surface pressure against any article (1) fed into the press. In that at least from the beginning of the vulcanizing operation to the end of it, a multitude of flow routes is established between the press shiftable part and each article (1) for vapors and gases released from each article (1), and a multitude of flow routes out from the press zone from where said vapors and gases may thus escape at least along part of the border of said press zone border, a method is brought about in which no vulcanizing heat is lost for heating of confined vapors and gases at high pressures.
