Abstract (en)

Filter plugs or sticks are directed from a filter maker onto a pair of conveyor rollers (19, 20) counter-rotating substantially in contact one with another at a point of tangency (30) and furnished with equispaced peripheral flutes (25) by which the single sticks (11, 12) are taken up and transferred from an infeed position (26, 27) to a release position (28, 29). The flutes (25) occupying a limited sector (41) of each roller (19, 20) are connected selectively to a source of suction by an internal valve mechanism (32, 39) composed of a slide (40) positionable to set the width of the sector (41), and a selector sleeve (32) slidable axially between operating positions in which suction is generated across the sector (41) through flutes (25) spaced apart respectively at a longer pitch (P), and at a shorter pitch (p) equivalent to half of the longer pitch (P).
