ABSTRACT:
A filter plug aligning device has an aligning drum having many feeding grooves on the outer peripheral surface thereof. As the drum rotates, each feeding groove receives a pair of charcoal tips and one plain plug while being separated from each other. On both sides of the feeding groove are formed leads, which extend along the feeding groove. Part of the outer peripheral surface of the aligning drum is covered by a sealing sheet, which forms the feeding groove into a tunnel-shaped passage. When the feeding groove which has received the tips and plug passes through the sealing seat, suction pressure is generated in the tunnel-shaped passage and air currents are generated in the leads of the passage. The suction pressure and air currents move the tips and plug in the feeding groove in one direction, and the movement of the tips and plug are stopped and aligned by a stopper ring fixed to the aligning drum.
