Abstract: Successive tubular wrappers of cigarette paper, which are conveyed sideways in the peripheral flutes of ail indelible rotary conveyor, receive elongated batches of smokable material during intervals of dwell at a filling station. The batches are introduced by an elongated channel-shaped implement which is reciprocable with a batch into, and without a batch out of, a wrapper at the filling station. The wrappers are propped by the concave surface of a pivotable holder during introduction of batches and the batch-receiving open ends of the wrappers are calibrated by causing them to move axially into a cylindrical portion of a passage in a mouthpiece at the filling station immediately prior to introduction of the batches.

Abstract: A container which is filled with an array of parallel hollow cylinders of cigarette paper is opened at the top and is overlapped by a retractible temporary cover prior to being partially inverted onto a downwardly sloping top wall of a magazine. The cover is thereupon retracted and the top wall is pivoted to permit entry of cylinders from the interior of the container into a chamber of te magazine. Such cylinders are thereupon caused or permitted to enter the flutes of an indexible drum-shaped conveyor which transports the cylinders seriatim to a station where successive cylinders receive rod-like fillers of particulate material, such as comminuted smokable material.

Abstract: Particles of comminuted smokable material are loosened in a downwardly converging compartment defined by a funnel-shaped array of intermittently driven endless flexible belts. The outlet at the lower end of the compartment delivers flows of loosened material into a receptacle wherein the level of the material is monitored and a motor for the belts is started to admit additional material into the receptacle when the level of material descends below a predetermined minimum level. The bottom portion of the reservoir can be expanded and contracted to convert the lowermost part of material in the receptacle into a succession of properly compacted batches each of which can constitute a rod-like filler, and such batches are thereupon evacuated longitudinally of the bottom portion of the receptacle into successive empty tubular envelopes which can be made of cigarette paper or other wrapping material for rod-shaped smokers' products.
