Abstract
Cigarettes in multi-layer stack formation are delivered from a maker (10) to a packer (12) on a path having a first junction (24) connected to a tray filling unit (30) and a second junction connected to a tray unloading unit (38). Control circuitry (54-72) is provided to control transfer of cigarettes at the first junction (24) according to the relative speeds of the maker and packer and/or the capacity of a reservoir (46) associated with the path. The control circuitry (54-72) prevents too frequent operation of a gate (32) associated with the first junction (24) and allows operation of the tray filling unit (30) at an optimum speed.
