  • the transfer drum 38 of the cigarette rod making machine ZM delivers two rows of plain cigarettes Z of unit length to a pair of aligning drums 52 in the machine FA.
  • the plain cigarettes Z of one row on the transfer drum 38 are staggered with reference to the cigarettes of the other row and the purpose of the drums 52 is to move each cigarette of one row into axial alignment with a cigarette of the other row.
  • the thus aligned pairs of cigarettes Zare introduced into successive flutes of an assembly drum 53 in such a way that the cigarettes of each pair are separated from each other by a gap having a width which at least slightly exceeds the length of a filter plug section of double unit length.
  • the filter cigarette making machine FA further comprises a magazine or hopper 54 for a stack of prefabricated filter rod sections of six times unit length which are discharged by way of a chute 54a to enter successive flutes of a so-called cutting drum 56 cooperating with two coaxial rotary disk-shaped knives 57 which sever each filter rod section of six times unit length so that each such rod section yields three coaxial filter rod sections or filter plugs of double unit length.
  • the plugs are transferred to three staggering drums 58 which move the originally coaxial plugs sideways with reference to each other so that the plugs are moved out of axial alignment with each other and are introduced into successive flutes of a shuffling drum 59.
  • the drum 59 cooperates with cams 59a to move the plugs axially so that the plugs form a single row which is transferred onto an intermediate drum 61.
  • the drum 61 delivers the plugs into successive flutes of an accelerating drum 62 which introduces such plugs into the gaps between successive pairs of plain cigarettes Z in the flutes of the assembly drum 53.
  • the drum 53 moves the resulting assemblies (each of which consists of two plain cigarettes Z and a filter plug between the respective plain cigarettes) along one or more condensing cams 53a which cause at least one plain cigarette Z of each assembly to move axially toward the other plain cigarette whereby the assemblies are condensed so that the inner ends of the plain cigarette Z abut against the respective ends of the filter plug therebetween.
  • the thus condensed assemblies are transferred onto an intermediate drum 63 which moves the assemblies past a suction drum 69 serving to provide each assembly with an adhesive-coated uniting band.
  • the uniting bands are obtained by severing the leading end of a web or tape 65 which is being withdrawn from a bobbin 64 and is caused to pass through the nip between two advancing rolls 66, 67.
  • the tape 65 thereupon advances along a paster 68 having a roller-shaped applicator 68a which coats the underside of the tape 65 with a film of adhesive.
  • the tape 65 thereupon reaches the suction drum 69 which cooperates with the blades of a rotary knife 71 to sever the tape 65 at regular intervals in order to form adhesive-coated uniting bands which are attached to the assemblies in the flutes of the intermediate conveyor 63.
  • Each of the thus attached uniting bands adheres to the respective filter plug and to the adjacent inner ends of the corresponding plain cigarettes.
  • each group is converted into a filter cigarette of double unit length.
  • the filter cigarettes of double unit length are transferred onto a testing drum 74 whereon the cigarettes are tested for the presence or absence of defects.
  • a suitable ejector device 226 (see FIG. 14) segregates satisfactory cigarettes from defective cigarettes.
  • the satisfactory cigarettes are transferred onto a cutting drum 76 which cooperates with a rotary disk-shaped knife 76a to sever each filter cigarette of double unit length midway between its ends to form pairs of filter cigarettes of unit length.
  • Each filter cigarette of unit length consists of a plain cigarette, a filter plug of unit length, and one-half of a uniting band which is convoluted around the filter plug and the adjacent end portion of the plain cigarette.
  • the two rows of filter cigarettes of unit length are thereupon transferred onto an inverting drum 77 which inverts the cigarettes of one row end-for-end and preferably places the inverted cigarettes between the cigarettes of the other row to'form a single row of filter cigarettes which are transferred onto an intermediate drum 78 prior to transfer onto a second testing drum 79 which tests the density of the exposed ends of tobacco fillers and cooperates with an ejector which segregates the defective filter cigarettes from satisfactory cigarettes.
  • a transfer drum 8] delivers satisfactory filter cigarettes onto one or more endless belts 82 for delivery to the tray filling machine, SF.
  • the moving parts of the filter cigarette machine FA receive motion from the motor 39 of the cigarette rod making machine ZM.
  • the detectors IFl to IF7 which monitor the operation of discrete processing units in the filter cigarette machine FA are distributed as follows:
  • the detector lFl (which can but need not constitute the detector IZ4 of the machine ZM) is adjacent to the transfer drum 38 to monitor the delivery of plain cigarettes Z of unit length to the machine FA.
  • the detector [F2 is adjacent to the path of the tape 65 which is to be severed to yield uniting bands.
  • the detector IF3 scans the supply of paste in the tank. 177 of the paster 68.
  • the detector IF4 is adjacent to the chute 54a of the maga- Zinc 54 to monitor the feed of filter rods of six times unit length to the cutting drum 56.
  • the detector IFS is adjacent to the inlet of the rolling gap 201 (see FIG. 12) between the drum 72 and the stationary rolling member 73 to detect eventual pileups of groups.
  • the detector IF6 is adjacent to the rolling drum 72 downstream of the rolling member 73 to scan the filter cigarettes of double unit length.
  • the detector IF6 is designed to detect the absence of filter cigarettes of double unit length.
  • the detector IF7 is adjacent to the testing drum 74 and is designed to produce signals in response to detection of a certain number of successive defective filter cigarettes of double unit length.
  • the de tails of the detectors [F1 to IF7 are shown in FIGS. 7, 9, 10,11, 12, 13 and 14.
  • FIG. 5 A tray filling machine SF which can be used in the production line of FIG. 1 is shown in FIG. 5.
  • This machine is of the type known as CASCADE and is produced by Hauni-Werke of H'amburg-Bergedorf, Western Germany.
  • the machine SF comprises a first station 91 for storage of empty trays 92 which are held in readiness for transport toward, past and beyond a tray filling station 98.
  • the means for moving the empty trays 92 off the station 91 comprises a combined lifting and transporting mechanism 93 receiving motion from a drive 94.
  • the mechanism 93 advances successive empty trays 92 sideways (in a directionto the left, as viewed in FIG.
  • the tray filling station 98 is adjacent to the path of trays 92 with the chain conveyor 97.
  • the aforementioned endless belts 82 of the filter cigarette making machine FA deliver a single row of filter cigarettes 99- of unit length to the station 98 and such cigarettes are picked up by a pneumatic row former 103.
  • the cigarettes 99 on the belts 82 move sideways in a direction at right angles to the plane of FIG. 5, and the underside of the row former 103 is provided with parallel flutes or receiving means 102 which receive filter cigarettes 99 and accumulate rows or layers containing predetermined numbers of such cigarettes.
  • the row former 103 When the row former 103 completes the formation of a layer or row, it is lifted above and away from the upper stretches of the belts 82 and the row is thereupon removed from the flutes 102 a direction to the right; as'viewed in FIG. 5, to be transferred into the adjacent tray 92 which is at a standstill whenever a fresh row is caused to leave the flutes 102.
  • the construction of the row former 103 is disclosed, for example, in US. Pat. No. 3,519,143 issued July 7, 1970 to Kochalski et al. This row former has a suction chamher 106 which is connected with the flutes 102 by channels 104 and insures that the row former can accumulate a row of closely adjacent filter cigarettes 99 which can be properly stacked in the adjacent tray 92.
  • the means for moving the row former 103 up and down comprises a drive 107.
  • the means for transferring rows of filter cigarettes 99 from the flutes 102 (in raised position of the row former 103) into the adjacent tray 92 on the chain conveyor 97 comprises a reciprocable transfer member or pusher 109 which receives motion from a drive 108.
  • the operation of the drive 108 is synchronized with that of the drive 107 for the row former 103.
  • the cigarettes 99 of the row which is being transferred from the flutes 102 of the row former 103 pass through suitable guide means or mouthpieces 111 and are deposited in the adjacent tray 92 on top of the previously transferred row.
  • the drive 96 thereupon causes the conveyor 97 to lower the tray 92 by a step so as to provide room for the delivery of a fresh row.
  • Thelength of each step is slightly less than the diameter of a filter cigarette 99.
  • the row former 103 accumulates a fresh row while the tray 92 at the station 98 descends, and the drive 107 thereupon lifts the row former with a freshly formed row in the flutes 102 before the drive 108 causes the pusher 109 to perform the next-working stroke and to push the fresh row of filter cigarettes 99 through the mouthpieces 111 and into the tray 92 where the fresh row comes to rest on the preceding row, preferably in such a way that the cigarettes in suc-
