980,935. Cutting tobacco. ROBERT LEGG Ltd. July 26, 1963 [July 31, 1962], No. 29419/62. Heading A4C. In a machine for compressing tobacco leafs prior to shredding leaf tobacco is fed from hopper 5 into the duct 1 of a tobacco cutting machine, the duct being enclosed by two vertical walls 2 and two conveyer belts 3 and 4. The tobacco is conducted by the conveyer belts under increasing compression to a mouth-piece 6 at which it is shredded by a shredder 7. The wall of the feeding area remote from the mouth-piece is comprised by the plate 8, of compactor 9, mounted at an angle of 35 degrees to the horizontal (i.e. an obtuse angle to conveyer 3) which is caused to vibrate orbitally over its whole area, by a mechanism mounted on anti-vibration mountings and including throw weights 10 clamped on a shaft carried in bearings mounted on a frame 11 and driven by a motor 12. The vibrator plate 8 in combination with the movement of conveyer belts 3 and 4 causes the leaves to flow in the direction shown by the arrows without the formation of voids and the straight lay of the leaves is retained and uniform compression exists through the mass at mouth-piece 6. Alternatively the compactor may comprise an orbitally vibrating conveyer belt movable towards conveyer 3 and mounted at an obtuse angle thereto
