<p>The device has two braking parts (4a, 4b) movable between a sliding position and a braking position. The braking parts comprise driving elements (45) and braking elements (41), where the braking elements are arranged at distance from the driving elements. A fastener (7) connects the driving elements and the braking elements with each other. The fastener defines multiple configurations for assembly of the driving elements and the braking elements to obtain different distances between distal ends (49) of the braking elements for the braking position.</p> |
