CHORDING AND TILTING FOR RAPID, UNAMBIGUOUS TEXT ENTRY TO MOBILE PHONES

This invention relates to an automatic control device adapted to regulate, without interruptions, cigarette-making process and in a substantially continuous way, the cut tobacco being re-circulated back to the distributor, as trimmed excess tobacco (S) from the uniform tobacco rod, formed in the pneumatic suction belt forming assembly (N) of a continuous cigarette-making machine. Said device substantially comprises a detector suction head (1), through which all of said trimmed excess tobacco (S) is passed pneumatically, in its path of suction re-circulation, from trimmer (R) of the belt (N) the distributor of the cut tobacco for the formation of the rod. Said detector suction head (1) is associated with a photo-cell sensor (4, 5) whose light beam is liable to be attenuated by the total flow of trimmed cut tobacco (S) sucked through said head. Depending upon the intensity of said attenuation, said optical sensor (4, 5) generates a primary measurement and control signal indicating the specific output of said excess tobacco. Associated with the detector suction head (1), inserted in the sucking ducts (2, 3) from the trimmer (R) to the distributor, is a regulatable means for controlling the total flowrate of the distributor, adapted to control said flowrate as a function of said primary measurement signal indicating the recirculated excess tobacco (S) to said distributor.
