Abstract
A device for supplying a succession of die cut tobacco blanks with a given profile to a web of a coiled type, storage bobbin. This device comprises a set of die cut stations each including a cutting die blade with an upstanding cutting edge matching the profile of the proposed blank and vacuum means surrounding the edge of the blade for capturing a tobacco sheet material on the stations in a position overlying the cutting edge. The stations are moved along an endless, preselected cutting path which intersects a cutting means at a first position in the path of movement of the stations so that a tobacco leaf can be cut from a manually placed tobacco sheet captured on the movable station. After passing the cutting means, which includes two rolls generally fixed in the direction of movement of the station, the station continues in the same endless path to a transfer position at which position the cut profile is released from the cutting station and is transferred to an awaiting web of a coiled type storage bobbin.
