ABSTRACT:
Method and apparatus for the removal of tobacco cuttings in the wrapper cutting portion of a cigar making machine in which a hollow, rotatable die turret having a pair of hollow die units on its upper surface, air openings at its lower surface and passageways from such openings to the interior of the units, is rotatably mounted on a stationary support having a pair of air chambers therein with openings in the upper wall thereof which permit air to flow into or out of the turret passageways through the openings at its lower surface at various portions of the cycle of rotation of the turret. Each die unit has holes around the periphery of the cutting edge which extend into the die unit interior. One of the chambers is kept continuously under vacuum so that during part of the rotation of the turret, air is drawn through the die unit holes to maintain a strip of tobacco on top of a die unit. The other chamber successively is a vacuum chamber, contains air under pressure or contains air at atmospheric pressure, a cycle which repeats. After the strip is cut and the cut strip is removed, the turret rotates and the other chamber which then contains air under pressure is connected through the turret to the interior of the die unit from which the cut strip was removed thereby causing air to flow out of the die unit holes and causing any tobacco cuttings to be dislodged. As the cuttings are dislodged, they are removed by a nozzle connected to vacuum means.
