Abstract
A cigarette manufacturing machine having an auxiliary recycled tobacco feed unit communicating with a downflow duct for feeding tobacco to a continuous cigarette rod forming section; the aforementioned auxiliary unit comprising an input conveyor belt communicating with a vibratory tray located between the output of the aforementioned conveyor and the aforementioned downflow duct; tobacco flow along the aforementioned input conveyor being regulated by mobile deflecting elements connected to means for controlling the tobacco level inside the aforementioned downflow duct.
Claims5
A cigarette manufacturing machine comprising:
- a main tobacco feed device (7);
- a downflow duct (8) for shredded tobacco, said duct (8) extending downwards from said main tobacco feed device (7);
- an intermediate lateral transverse aperture (20) provided in said duct (8) and extending over the whole width thereof;
- an auxiliary tobacco feed unit (17) communicating with said duct (8) at said aperture (20);
- the auxiliary feed unit (17) comprising tobacco conveying means (16, 18) having an output end arranged at said aperture (20) and fixed in relation thereto, and tobacco deflecting means (31, 32;
- 42, 44) associated with said conveying means (16, 18) to displace the tobacco conveyed thereby in relation to said conveying means (16, 18) and crosswise in relation to a traveling direction thereof;
- and
- detector means (37) for detecting the levels of tobacco at a number of points across said duct (8), and for controlling said deflecting means (31, 32;
- 42, 44) to maintain said levels within a predetermined range of variation.
