ABSTRACT:
In a processing device which includes a pair of rotatable rolls and a support for supporting a coil of foil-like material, a device is provided for feeding the leading end of the outer turn of the coil of foil-like material into the gap between the rolls. The device comprises a structure which is movable along a path which brings it close to the periphery of the coil and to the roll gap. The structure includes suction apparatus for picking up the outer turn of the coil and apparatus for blowing air over a surface of the leading end of the foil to cause the leading end to tauten and enter into the roll gap.
