Abstract
L'invention concerne un rouleau destiné au transport du verre plat à haute température, pendant des durées prolongées, sans détérioration de la surface du verre avec laquelle ce rouleau est en contact Le rouleau est constitué de minces disques d'amiante 16 comprimés axialement sur un mandrin 15. L'amiante est imprégnée d'une solution de sulfate de potassium, puis séchée totalement avant la mise en service du rouleau 12. Les cristaux de sulfate de potassium lubrifient la surface du rouleau tout en minimisant la détérioration causée par ce dernier au verre chauffé. Application fabrication du verre flotté.
