ABSTRACT:
In a machine utilizing rolls of strip material for whatever purpose, typically a wrapping machine, the depleted rolls are replaced by new rolls taken up in succession from a magazine by a transfer unit including a gripping head that can be traversed along a guide, which in turn can be rotated about and reciprocated along the dispensing axis of the magazine. Being thus rotatable about a permanent axis, the guide can be made selectively to assume different angular positions, each coinciding with a line connecting this same axis with the axis of a respective uncoiling pivot provided by the machine.
