A device for controllably influencing the friction forces between the guide surfaces and the contact surfaces of bearing chocks of the rolls guided in the housing windows of roll stands includes planar support plates for supporting the guide surfaces, wherein the support plates are guided so as to be slidable perpendicularly relative to the guide or contact surfaces of the housing window and the bearing chock, and wherein a device is provided for applying pressure to the rear side of each support.
Dispositif pour influencer de manière contrôlée les forces de frottement entre les glissières et les surfaces de contact de cales de coussinets des rouleaux guides dans les fenêtres de logement de dévidoirs, qui inclut des plaques de support à surface plane pour soutenir les glissières, où les plaques de support sont guidées, de manière à pouvoir coulisser perpendiculairement par rapport aux glissières ou aux surfaces de contact de la fenêtre de logement et des cales de coussinets, et où un dispositif est prévu pour appliquer une pression vers le côté arrière de chaque support.
