Abstract
A braking mechanism for a tape transportable in opposite directions between two winding hubs, to prevent development of slack. Each hub has an associated brake disc and band, opposite ends of each brake band being connected to arms on different pivotal levers at different lever arm distances, interconnected so that unwinding braking forces are larger than winding braking forces.
