Abstract
A continuous-rod cigarette-making machine of the type in which tobacco is conveyed from a hopper to a winnowing zone and there thrown across a rising airstream which entrains the tobacco and carries it up to the lower face of a suction conveyor on which a tobacco filler is formed has sealing means associated with conveying means for transporting the tobacco from the hopper to the winnowing zone, said sealing means opposing air flow between the hopper and the winnowing zone to reduce disturbance of the tobacco during its transport by the conveying means.
Claims9
In a continuous-rod cigarette-making machine with a suction conveyor on which a tobacco filler is formed in which tobacco is thrown as separated particles in a generally horizontal direction across a rising airstream in a winnowing zone so that said airstream entrains the tobacco and carries it up to the lower face of said suction conveyor, and with a hopper and conveying means for transporting the tobacco from said hopper to said winnowing zone, the improvement comprising sealing means associated with said conveying means, said sealing means being arranged to oppose flow of air between the hopper and the winnowing zone so as to reduce disturbance of the tobacco during its transport by the conveying means.
In a tobacco processing machine wherein a stream of particulate tobacco is winnowed by projecting said tobacco stream and an airstream respectively along transverse intersecting paths so that said airstream entrains said particulate tobacco in a winnowing zone and means is provided for conveying said particulate tobacco stream along a further path towards said winnowing zone;
- the improvement comprising sealing means arranged to cooperate with said conveying means to oppose flow of air along said further path towards said winnowing zone whereby disturbance of said particulate tobacco during transport by said conveying means is reduced.
