Abstract
A method of producing two continuous streams of cigarettes, whereby a continuous paper strip is cut longitudinally into two strips which are fed, through a tobacco loading station and along respective guides for forming respective continuous cigarette rods, to a transverse cutting device by means of respective conveyor belts looped about a number of common pulleys and more specifically about a common drive pulley, and the speed of which is controlled by respective tensioning devices operating at the same pressure.
Claims3
A method of producing two continuous streams of cigarettes, including the steps of cutting a continuous paper strip (4) longitudinally into two strips (8, 9);
- feeding the two strips (8, 9) through a tobacco-loading station (18) and along respective guides (21) by means of respective endless conveyor belts (16, 17), each belt being wound about a number of guide pulleys (27, 28, 31) and a drive pulley (29), for forming respective continuous cigarette rods (22, 23);
- advancing the cigarette rods (22, 23) to a transverse cutting device (24);
- and operating the cutting device (24) to transversely cut the cigarette rods (22, 23) into said two streams of cigarettes;
- each of said guide and drive pulleys (27, 28, 29, 31) engaging both conveyor belts (16, 17), the speeds of the conveyor belts (16, 17) being controlled by subjecting both conveyor belts (16, 17) to the same tensile stress as the strips (8, 9) are fed forward.
