Abstract
A cigarette reversing apparatus comprises a rotating transfer drum having a plurality of openings arranged equidistantly along the circle on the end surface of the drum, the openings being communicated with suction holes formed at the bottom of slots which are formed in the peripheral surface of the drum. A control ring faces the openings in the drum and has a suction distribution chamber spanning a cigarette overturning section of the drum. A rotating ring is slidably and rotatably interposed between the transfer drum and the control ring, the rotating ring being eccentric with respect to the drum and having a plurality of communication holes communicating with both the openings and the suction chamber. The communication holes are arranged equidistantly along a circle at intervals or pitches two times those of openings, the number of communication holes being half of the even number nearest to the odd number of the openings; whereby as the transfer drum makes a complete turn, the rotating ring is rotated at a speed corresponding to 1/2 pitch of the communication holes faster or slower than the drum so that suction is applied only to the every other slot where the cigarettes are installed so as to overturn the cigarettes efficiently.
