ABSTRACT Unwinding arrangements for material webs which are consumed continuously by e.g. packing machines are provided frequently with an arrangement which brakes the roll so that it does not continue to rotate when the unwinding ceases. To make possible a well adapted braking, also in the case of thin, delicate webs or strips and heavy rolls, the unwinding arrangement in accordance with the invention is provided with a maneuvering arm adapted to be acted upon by the material, which in the event of changes in the web tension presses with varying force a rotatable braking appliance against a brake drum combined with the material roll.
