摘要：The object of the invention is a feeding device for withdrawing from a feedinghopper (1) rod-like articles, particularly filter plugs in the manufacture of filter-tipped

cigarettes, and for singling same. The device comprises a rotary fluted drum (2) formingat least part of the bottom of hopper (1), and a repelling roller (13) that is arrangedbetween the wall (9) of the hopper (1) and the said drum (2), in correspondence of theend from which the said drum comes out of the hopper, and that is rotated in acontrolled manner in the same direction as the drum. The repelling roller (13) is somounted as to be movable substantially parallelly to the peripheral surface of drum (2)and, more particularly, it is carried by a lever (10) that is swingable about a shaft (4) whichis concventric or close to the shaft (6) for the rotation of the drum. The repelling roller(13) is urged by return means (14) toward a normal operative position in which it pushesback the rod-like articles not contained within the flutes (102) in drum (2), and preventssame from getting out of the hopper (1) or from becoming wedged between the wall (9)of the hopper and the drum (2). The abnormal, deformed, or aggregated rod-like articleswhich are engaged in one flute (102) in drum (2), and protrude therefrom to a greaterdegree than the normal one, push the repelling roller (13) toward a displaced position inwhich sensor means are actuated and determine the stopping of drum (2) and/or of themachine associated with the feeding device. The travel of the repelling roller (13) from itsnormal operative position to its displaced position is a relatively long travel, so taht theroller is given the possibility of pushing back the abnormal article or articles or ofloosening their clusters, before promoting the stopping of the drum or of the machine.
