Abstract
A reversible reservoir for cigarettes or filters includes relatively small and relatively large capacity sections arranged in series with a drive for driving these sections at different rates. The small section is preferably arranged adjacent the reservoir inlet and is capable of buffering the main part of the reservoir so that the latter is not required to undergo high accelerations. The reservoir may be in the form of an elongated helix with an endless conveyor (2;102) passing around spaced columns of wheels (8, 10, 12, 14, 16; 108, 112, 114), one of the lowermost wheels (8;108) being bodily movable so as to be capable of imposing an additional velocity on the section of conveyor adjacent the reservoir inlet (7;107). The movable wheel is carried on a (36;136) which also carries a pulley (26;126) for the conveyer return run. Tensioning (42-50;142-150) for the conveyor is provided by arranging for the position of the pulley (26;126) to be adjustable relative to the beam (36;136).
