Abstract
The object of the invention is a device for withdrawing rod-like articles (B) from a feeding hopper (1). More particularly, the invention provides a device for withdrawing filter plugs for the manufacture of filter-tipped cigarettes. A portion of the hopper bottom is formed by a fluted drum (2) for receiving one rod-like article (B) into each one of its flutes (3) at the time of its passing by the feeding hopper (1). A portion of the hopper bottom, which is adjacent to the fluted drum (2), is formed by at least one endless conveyor belt (7) having a width which is sensibly smaller than the length of the rod-like articles (B) and the length of the fluted drum (2). The upper branch of the conveyor belt (7) entrains articles to the drum flutes and gets into and through a respective peripheral annular groove (6) in the fluted drum (2), at least as far as to substantially reach the path of the bottoms of the drum flutes (3) situated at both sides of the groove. The conveyor belt (7) preferably is a suction belt, and is led around the fluted drum (2) on the bottom of the peripheral annular groove (6) in the drum.
