ABSTRACT:
Apparatus for accumulating arrays of superimposed layers of parallel cigarettes has a magazine with three layer-accumulating sections having outlets at different levels and a set of pushers which expel layers of cigarettes from the sections during the intervals of dwell of an intermittently driven conveyor for a set of receptacles each of which accumulates an array by accepting one layer from each of the sections. The top and side walls of the receptacles have aligned slots for stationary and movable portions of retaining devices which prevent the cigarettes forming layers of incomplete arrays from moving relative to each other during abrupt acceleration and deceleration of the conveyor to move the receptacles from section to section. The undersides of movable portions of the retaining devices can be raised above or lowered into alignment with the undersides of the adjacent stationary portions through distances approximating the thickness of a layer. The movable portions are disposed in pairs at the second and third sections, and the stationary portions extend along the first section as well as between successive sections. The first movable portions of the two pairs are connected to each other for simultaneous up-and-down movement, the same as the second movable portions of the two pairs. All of the movable portions are lifted simultaneously when the conveyor comes to a halt, and the first portion of each pair is lowered ahead of the respective second portion while the conveyor is in motion.
