A movable, vertical friction wheel (8) can be pressed against the belt (7, 7') and there is a connection (belt drive 10) between the friction wheel (8) and the driven motor (11). A motion device (9, 15, 16, 17) moves the friction wheel vertically (8). The bell (7') rotates on a wheel (2) which drives the cutting blade (6) and the motion device can be a manually operated lever (9) or tension cable (17).</p> |
