Abstract
An apparatus for preventing defective packing of cigarets wherein a presser which moves a plurality of cigarets arranged on two or three steps so as to be packed at a fixed velocity in the lengthwise direction of the cigarets along a frame is provided, a plurality of contact arms opposed to the respective cigarets arranged on the uppermost step are respectively independently rotatably supported on a shaft arranged above and at right angles with the frame, each contact arm is fitted with a shielding plate at the upper end and with a roller at the lower end so as to be suspended by the self-weight of the roller and to be pressed to rotate by the cigaret on the upper step with which it contacts, on the other hand, a sensing lever rotated by a supporting shaft is projected at right angles with the advancing direction of the cigarets on the side of the lower step of the cigarets so as to rotate clockwise and anticlockwise against a spring and to be pressed to rotate by the side of the cigarets with which it contacts and a shielding plate is fitted to the supporting shaft so as to normally intercept a beam from a projector and to open the beam when rotated.
