Abstract
An apparatus for the high speed transportation of cigarette filter rods from a magazine containing the rods to a transfer drum. The apparatus has a magazine, a downwardly extended chute connected to the magazine adapted to receive filter rods singularly, a rod separation means at the junction of the magazine and chute, and a vacuum means adjacent to the chute exit. The vacuum means creates a negative pressure within the chute to hold the lowermost rod in the chute in a fixed position for accurate transfer to the transfer drum.
