TODAY’S PATENT- MOUNTING A PRESS SHELL TO A PRESS ROLL FOR DEWATERING A WEB

Today’s patent was invented by Hans Flaming, Andreas Schutte, Christian Schiel, Karl Steiner, and Josef Mullner on July 31, 1990, bearing patent no. US4944089A.

The present invention relates to a press roll which serves for treating material in web form. It includes a support body that is either stationary or rotatable and a press shell that is rotated over the support body and against a mating roll. A respective shell support element or disc is disposed of axially outward of both ends of the support body and the support element has an axially outward face side. The flexible, liquid impervious endless belt press shell has lateral edge zones.

That each zone has a respective plurality of outwardly projecting tongues and has cutouts between neighboring tongues. The edge zone is turned radially inward and its tongues are each respectively mounted on a holding element projecting from the face side of the shell support element. The object of the present invention is to improve the press roll in such a manner that the centering and attachment of the ends of the press shell to the shell support elements can be carried out more dependably and faster than up to the present time.
