The invention, therefore, is not to be restricted tothe specific construction shown and'described.` l

` Referring to Figs. 1, 2 and 3, the improved tobacco feeding channel consists of an endless horizontal belt driven at arsuitable speed 10 ovena'sup'port table 11 onto which it is guided by a pulley 12 mounted on ya shaft 13,A

and of two endless vertical belts 14 running at the same speed over flanged pulleys 15 which run in opposite directions and guideV l 15 their inside loops onto the horizontal belt 10.

Thepulleys 15 turn on shafts-16 supported by a bracket 17 attached to the frame of the tobacco feed. The insideloops of the belts 14, which form the moving side wallsk of the vtobacco feed channel, are'supported byfcastings 18 which fit into the spaces between-the loops of each of the belts 14 and are fastened to table 11.

To the top of each of the castings 18 is fas- 25 tened, by means -of screws 19, a guard 2O which projects over and along the outerloop of belt 14. To prevent the edges of the'tobacco leaves T from turning up in the feedv channel, the guards 20 are extended inwardly 3Q! and downwardly to form ledges 21 projecting into the tobacco channel near each wall and presenting flat horizontal surfaces which hold down the opposite'edges of any broad tobacco leaves which may be inserted into the feed channel. 1 Y Y The edges and points of any narrow leaves which may not be held down by the ledges 21 are guided by lead-in plates 22, which are adj ustably attached to the guides`20 by screws of 23, against an inclined` endless belt 24 running over pulleys l25 and 26, on shaft 27 and stud V28 respectively, and driven at high speed bya belt 29 running over pulley 30 on shaft Y 27. Stud 28 is stationarily supported by a '4*5-4 plate 31 attached at its upper end to frame 32 of themachine, while shaft 27 is adjustably mounted in arms 33 pivoted on stud 28 and held at the proper angle by a bolt 34 adjusta- .6oby the belt. The lforward end of this stripper is cut into individual prongs between and outside of which pass the prongs 43 of vthe compacter k44 so that the Vtop leaves of the tobacco layer T in the feeding channel are guided head-on under the c ompactor, from which the compacted tobacco layer is cary ried to devices, not shown, for measuring and cutting the tobacco into filler for the cigar bunches which are formed in the cigar machine.
