ABSTRACT:
A continuously-operating vulcanizing press, in which the article which travels through the press is guided on both sides between flexible enclosing strips which travel along with the article. A pressure mechanism, which acts upon the enclosing strips, is provided in the entry region of the press in order to already produce direct contact of the strips with the side edges of the pressed article in the starting phase of the vulcanization. In contrast to the heretofore known arrangement, which is disposed at a distance ahead of the press, the inventive arrangement provides a considerably more precise guidance of the enclosing strips, and hence also provides a qualitative improvement of the end product.
