Filter rods of predetermined length are placed in a hopper and fed to a slitting drum. This drum contains flutes divided into four groups, two of which are separated and their flutes are open whereas the other two groups of flutes are closed. The rods are received in the open flutes and there they are cut by a series of rotary knives into equal sections to provide filter plugs. The adjacent group of closed flutes in the path of rotary travel of the drum permits the cut filter plugs to be directed to a bagging station at which they are enclosed in a bag before the next group of cut filter plugs are permitted to pass through to the bagging station. As the cut filter plugs leave the slitting drum, they are directed into a funnel which has associated therewith a gate. The gate closes off the base of the funnel until the preceding group of cut filter plugs are completely enclosed in a bag. Thereafter, the hate is opened to permit the collected plugs to pass through to the bagging station. At this station a web of heat sealable wrapping material is fed into a tube former which forms the wrapping material into a tube which extends vertically. A heat sealer seals the overlapped marginal side edges of the tube of wrapping material. A pair of opposed and reciprocal heat sealers operates to heat seal and close the lower end of the tube at which the group of cut plugs collect. When the predetermined number of cut filter plugs is collected, the pair of reciprocal heat sealers are reciprocated to heat seal and close the tube above the group of collected plugs. This upper heat sealed zone is cut along an intermediate section to thereby produce a severed bag of filter plugs and at the same time provides the heat sealed and closed lower end of the next bag to be formed. The filled and severed bags are then permitted to drop and be collected in a suitable receptacle.

There is disclosed apparatus in a high speed continuous cigarette processing plant for maintaining substantially constant the length of an accumulated layer of cigarettes. The apparatus comprises a carrier for carrying cigarettes in a predetermined direction, a charging device to displace the cigarette transversely to the respective longitudinal dimensions thereof and thereby to load the cigarettes onto the carrier to be accumulated thereon side-by-side in a single gapless layer, and a discharging device disposed downstream of the carrier to remove the cigarettes in uniform sequence from the carrier. The apparatus further comprises a device to provide a target signal indicative of the optimum length of the accumulated layer of cigarettes, a first sensor disposed to sense the passage of each cigarette loaded onto the charging device from the carrier and to provide a first signal indicative of the passage of each cigarette, a second sensor disposed to sense the passage of each cigarette removed from the charging device to the discharging device and to provide a second signal indicative of the passage of each cigarette, a reversible digital counter arranged to count forwardly in response to the first signal and to count backwardly in response to the second signal, and a control device responsive to a control signal indicative of an instantaneous count state of the reversible digital counter and responsive to the target signal to so control the rate at which the cigarettes are removed from the carrier by the discharging device that the length of the accumulated layer of cigarettes is maintained substantially constant.

A funnelling device for use in a cigarette packing machine is disclosed. Cigarettes are fed into the mouth of a funnel-shaped housing from a container, which contains cigarettes and is mounted above the inlet mouth of the funnel. A displaceable shutter is disposed between the bottom of the cigarette container and the mouth of the funnel to control the flow of cigarettes. The funnel housing comprises vertically extending walls, which define the inlet mouth at the top of the funnel. A pair of deflector members are pivotably mounted in the funnel housing below the mouth. These deflector members are each pivotably displaceable through a predetermined angular displacement about a respective horizontal axis, and each deflector member has an exterior surface portion of substantially spiral-shape centered on the respective axis of rotation. In use, the deflector members are pivotably displaced so as to raise them and, thereby, to raise the level of cigarettes remaining in the funnel-shaped housing during periods when an emptied cigarette container is being replaced by a replenished one. In this way the distance, through which cigarettes have to drop from a replenished container before striking the uppermost layer of cigarettes remaining in the funnel-shaped housing, is minimised. The deflector members are so shaped and mounted that substantially no risk of crushing cigarettes against the walls of the funnel arises when the deflector members are upwardly angularly displaced. Expediently, the deflector members are angularly displaced by displacement means automatically controlled by sensing means, which is responsive to the level of the uppermost layer of cigarettes in the funnel to generate electrical control signals.

The operation of a single machine or a group of two or more machines for the production and/or processing of smokers'' products is monitored by detectors serving to measure the quantity of comminuted tobacco or filter material which is admitted at each inlet and discharged at each outlet of the machine or machines. The detectors produce electric signals for evaluation by a computer or by a system of totalizing, multiplying and/or dividing circuits which furnish indications of the ratio of admitted to discharged quantities of tobacco or filter material.

A marking device for the wrapper in a cigarette-making machine including a photoelectric device for counting cigarettes at the discharge end of the machine arranged to energize an electromagnet which moves a pencil into momentary contact with the wrapper tape within the machine. When a preselected number of cigarettes has been counted, a drum having a peripheral lug rotates to close a switch which energizes the electromagnet.
