<p>A device for accumulating and supplying lengths of material in sheet form or in cuttings, such as, for example, labels, adhesive stamps, revenue stamps, coupons and cuttings of various shapes, etcetera, to be used in wrapping machines in conjunction with a fixed container or vertical well-shaped cavity from the base of which the cuttings are removed so that they can be supplied to the wrapping units of a wrapping machine. This device consists of a cylindrical body which is rotatably supported around its vertical shaft above the well-shaped cavity and is provided with a plurality of peripheral compartments, each of which is able to contain a pile of cuttings. A plurality of movable supports is provided for supporting a given pile of cuttings at a point inside the compartments corresponding to where the base of the stack is located. The cylindrical body is caused to rotate in an intermittent fashion in such a way as to cause the compartments to halt, one at a time, in alignment with the aforementioned well-shaped cavity responsive to a photoelectric sensor sensitive to the level of the pile of cuttings in the inside of the well-shaped cavity. This allows the subsequent transfer of the cuttings from the compartments to the well-shaped cavity once a predetermined level has been reached inside the cavity.</p> |
