<p>A method and apparatus for producing open-sided V-belts by cutting from a vulcanized, sleeve-shaped roll. The sleeve-shaped roll is disposed over two drivable rollers. A tensioning arrangement which includes one of the rollers has a weight. This weight acts solely on such roller tending to pull this roller away from the other roller. This tensions the roll. When the tensioning force attains a predetermined limit, it is partially counteracted by a force acting in the opposite direction. The counter-acting force is supplied by suitable means. Cutter means are provided for cutting the roll while it is tensioned and the counteracting force is increased by suitable means in dependence upon the number of belts cut from the roll.</p> |
