Abstract
Cigarette rolling and forming devices include parallel cylinders extending between a pair of support plates, and a looped belt trained therearound. One cylinder is moveable relative to the other for alternately receiving and compressing loose tobacco into a tobacco rod with the belt. In some devices, a pair of slots allows movement of the cylinder, and guard plates are disposed to prevent tobacco from the belt from entering the slots. Some devices include two pairs of slots and two moveable cylinders. Some devices include a support trough disposed to prevent sections of the belt from contacting each other. Some devices include a folding device configured to engage and fold the edge of a piece of paper received between the cylinders and rolled around the tobacco rod. Some devices include a nozzle to retain a pre-formed tube and a pushing device adapted to push a formed tobacco rod into the tube.
