Device for receiving and transferring cylindrical filter rods from a mass flow of filter rods being conveyed

A device for receiving and transferring cylindrical articles having a preselected radius one at a time from a mass flow of parallel articles being conveyed along a conveying path in a direction transverse to their longitudinal axes comprising:

• a stationary first semi-cylindrical filter receiving body disposed across the conveying path with its longitudinal axis transverse to the conveying path such that it is parallel to the longitudinal axis of the cylindrical articles being conveyed and concavely facing in the upstream direction of the conveying path, the inside radius of the first semi-cylindrical body being substantially equal to the radius of the cylindrical articles;
• a rotatable second semi-cylindrical body substantially longitudinally coextensive with and concentrically disposed with the first semi-cylindrical body and having an inside radius substantially equal to the outside radius of the first semi-cylindrical body;
• means for rotating the second semi-cylindrical body between a first position wherein the second semi-cylindrical body overlaps the first semi-cylindrical body and a second position wherein the second semi-cylindrical body concavely faces the first semi-cylindrical body defining a generally cylindrically shaped enclosure between the first and second semi-cylindrical bodies;
• and,
• means for moving a cylindrical article captured in the generally cylindrically shaped enclosure longitudinally thereof and out of the generally cylindrically shaped enclosure through an open exit end thereof.
