Abstract
Unwinding arrangements for material webs which are consumed continuously by such as packing machines which 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 well adapted braking, 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 a varying force a rotatable braking appliance against a brake drum combined with the material roll.
