Abstract: This application describes various possible modifications in the cigarette machine hopper described in G.B. specification No. 2,045,595. In particular, as shown in FIG. 2, a concave member 126 around a carded roller 23 from which tobacco is removed by a picker roller 24 has a straight land 126A along which the tobacco is propelled by the picker roller.

Abstract: This invention is concerned with the manufacture of double cigarette units each consisting of a double-length tobacco rod having filters secured to its opposite ends. Cutting in half of such double cigarette units to form separate filter cigarettes may be delayed until just prior to packing of the cigarettes, until which time the filters at the ends of the double cigarette units seal in the tobacco. The manufacture of double cigarette units according to this invention is an in-line process in which double tobacco rods and intervening double filters are joined by portions of tipping paper while moving axially so as to form a continuous rod which is then cut through the middle of the double filters to produce the desired double cigarette units.

Abstract: In the hopper of a cigarette making machine the tobacco slides down a ramp into a narrow downwardly extending channel situated at a position spaced from the area in the hopper which initially receives the tobacco. The tobacco is fed upwardly from that area by a spiked elevator band and is then removed from the spiked elevator band and transferred to the downwardly extending channel by further conveyor means.
