Abstract: Apparatus for removing filter cigarettes from a mass flow between one or more producing machines and one or more processing machines when the output of the producing machines exceeds the requirements of the processing machines, and for returning filter cigarettes into the mass flow when the requirements of the processing machines exceed the output of the producing machines, has a filling unit which withdraws cigarettes from the mass flow and introduces them into successive empty chargers or trays, and an emptying unit which dumps the contents of filled trays into a receptacle for reintroduction into the mass flow. The emptying unit is located at a level above the filling unit, and each of these units cooperates with two magazines, one for empty trays and the other for filled trays.

Abstract: A multi-layer stream of cigarettes is transported from a making machine to a packing machine by way of a first and a second junction. The first junction diverts some or all of the cigarettes from their path and into a tray filler when the output of the making machine exceeds the requirements of the packing machine, and the second junction receives some or all of the cigarettes from a magazine filler when the requirements of the packing machine exceed the output of the making machine. A trickle of cigarettes can flow into the tray filler and a trickle of cigarettes can flow from the magazine filler even at such times when the requirements of the packing machine match the output of the making machine. This prevents moving cigarettes from rubbing against one and the same group of stagnant cigarettes which fill the location where the first junction can discharge cigarettes into the tray filler and the location where the second junction can receive cigarettes from the magazine filler.

Abstract: The lower end portion of a magazine for parallel cigarettes or like rod-shaped articles contains a horizontal grid of parallel rods which divide the outlet opening of the lower end portion into parallel passages wherein the cigarettes descend into an empty tray therebelow. When the tray is filled (such filling takes place while the tray descends, either continuously or stepwise), the passages are blocked by rod-like closing members which are parallel to the rods of the grid and are movable from inoperative positions behind the rods of the grid to intercepting positions in or above the passages. The closing members are oscillated and/or vibrated to prevent jamming of passages and/or bridging of cigarettes above the grid. The mechanism for moving the closing members between inoperative and intercepting positions employs a pneumatic motor or an electromagnet which can shift a common carrier for the closing members. The mechanism is actuated in automatic response to completed filling of a tray.

Abstract: Groups of coaxial filter rod sections and plain cigarettes are delivered onto the peripheral surface of a rotary drum in such orientation that each group extends in parallelism with the axis of the drum and overlies the adhesive coated outer side of a discrete uniting band which adheres to the surface by suction and is formed on the drum in such a way that its leader overlies a groove in the surface. The cigarettes of each group are attracted to the drum by suction, and the sections of the groups are mechanically urged against the leaders of the respective bands by claws which are retractible into and extendable from the drum by one or more stationary cams, followers which track the cams and gears which receive motion from the followers and rotate discs having eccentric pins coupling them to the respective claws.

Abstract: Apparatus for transporting rod-like articles in the form of cigarettes or filter rod sections from one or more makers to a packing or other consuming machine has a pair of superimposed surge bins which receive articles from a first transporting unit when the output of the maker or makers exceeds the requirements of the consuming machine, and a second transporting unit which conveys articles from the surge bins to the consuming machine when the requirements of the consuming machine exceed the output of the maker or makers. A control system is provided to effect the filling of the upper surge bin prior to filling of the lower surge bin and to effect evacuation of the contents of the lower surge bin prior to evacuation of the contents of the upper surge bin. Each transporting unit has one or more pairs of endless belts and/or ducts which convey multi-layer streams of articles.

Abstract: Apparatus for transporting cigarettes or analogous rod-shaped articles from one or more makers to a packing machine has a transporting system consisting of belt conveyors and one or more ducts which advance the output of the makers into the inlet of an upright channel serving to deliver the cigarettes to the packing machine. When the output of the makers exceeds the requirements of the packing machine, the surplus is diverted from the discharge end of the transporting system into one or more variable-volume surge bins by way of a reservoir wherein the height of the cigarette stream exceeds the height of the stream in the transporting system but is less than the height of the stack or stacks of cigarettes in the surge bin or bins. The reservoir has one or more conveyors which can advance cigarettes from the transporting system into the surge bin(s) or from the surge bin(s) into the channel.

Abstract: Apparatus which delivers rod-shaped articles, such as cigarettes or filter rod sections, from a producing machine to a consuming machine has a switching unit whose inlet receives articles from the producing machine, one outlet of which can feed articles to a first transporting unit for admission of articles into a surge bin cooperating with a second transporting unit for delivery of articles to one side of the magazine of the consuming machine, and another outlet of which can feed articles to a third transporting unit for direct delivery of articles to another side of the magazine of the consuming machine. The third transporting unit delivers articles to the magazine when the latter is not filled to capacity, and the first transporting unit delivers articles to the surge bin when the magazine is filled to capacity.

Abstract: The mass of successive increments of a wrapped rod-like filler of filamentary filter material is monitored by a beta ray detector and the signals which are generated by the ionization chamber of the dectector are utilized to adjust the ratio of a variable-speed transmission which regulates the rate of delivery of a stretched tow of filamentary material to the gathering horn of a filter rod making machine.

Abstract: A holder which is turnable about a horizontal axis supports two carriers for filled or empty trays. The holder moves one carrier with a filled tray therein from a first station to a second station where the carrier deposits the filled tray, in inverted position, on top of the magazine of a packing machine, while the other carrier moves back from the second to the first station. The carriers are pivotable relative to the holder so that a carrier with a filled tray therein can descend on top of the magazine during the last stage of movement to the second station and that the carrier with an empty tray therein is lifted above the magazine during the initial stage of its movement from the second station. This is achieved by connecting the carriers to links which are pivoted directly to the holder or to a lever which is rotatable by a shaft eccentrically mounted in the interior of a hollow cylinder serving to turn the holder.

Abstract: A storing unit with a series of discrete and separately operable magazines is adjacent to the path of cigarette packs which are transported by a conveyor from a packing to a processing machine. First blocking devices are located downstream of those sections of the path which are adjacent to the magazines, a second blocking device is installed ahead of the foremost magazine, and a third blocking device is installed ahead of the second blocking device. When a magazine is to receive a row of packs, the corresponding first blocking device is moved into the path together with the second blocking device whereby the latter intercepts the oncoming packs and is removed from the path when the number of intercepted packs matches a preselected number. The thus obtained group is thereupon permitted to advance toward that first blocking device which extends into the path. At the same time, the third blocking device intercepts packs ahead of the second blocking device.

Abstract: Apparatus for treating biscuits which are discharged from an oven in the form of several rows has a discrete conveyor system for each row of biscuits. The biscuits of each row are converted into blocks each consisting of several arrayed biscuits, and such blocks are confined in wrapping material on their way to variable-output packing machines, one at the discharge end of each conveyor system, and each provided with turrets which convert blanks into containers for one or more wrapped blocks of biscuits and fill the containers. If a packing machine breaks down, the blocks on or in the respective conveyor system are transferred onto or into the other conveyor systems, and the output of packing machines at the discharge ends of the other conveyor systems is increased. Facilities are provided for temporary storage of blocks when the rate at which one or more conveyor systems deliver blocks to the respective packing machines exceeds the capacity of such machines.

Abstract: Apparatus for producing composite filter plugs for cigarettes or other smokers' products has two sets of conveyors which feed filter rod sections of different types to the flutes of a rotary assembly conveyor. The latter assembles the sections into groups each having a section of first and second type and moves the groups to an auxiliary conveyor which transports the groups sideways to successive pneumatic holders of a transfer conveyor. The transfer conveyor has two carriers which rotate about parallel axes and are coupled to each other by linkages, one for each holder. The linkages cause the holders to rotate relative to that carrier which supports the holders so that the orientation of holders remains unchanged during travel through 90.degree. or 270.degree. when the groups are taken over by successive increments of a web which is moved lengthwise and is draped around the resulting rod-like filler to form therewith a rod.

Abstract: A link chain which transports and compacts tobacco leaves in a tobacco shredding apparatus has a succession of neighboring metallic links each of which has a trailing end provided with a cylindrical male coupling portion extending into and turnable in a complementary socket at the leading end of the next-following link. The socket is formed at the inner side and the coupling portion is at the outer side of the respective link. Each outer side has a convex cylindrical surface at its front end, and such surface slides along a complementary concave cylindrical surface at the rear end of the outer side of the preceding link. Each link is further formed with a scraping edge which cleans the convex cylindrical surface of the next-following link. The convex cylindrical surface of each link bounds a portion of a recess which is formed in the outer side and is adjacent to the coupling portion of the respective link.
