Definitions

  • the present invention relates to leaflet folding apparatus, and more particularly to leaflet folding apparatus which incorporates a pressure roller unit which ensures that the folded leaflet maintains its flatness after folding.
  • a leaflet is folded into a desired configuration and then conveyed to a flattening roller unit which is some distance, typically 1 metre, away.
  • a flattening roller unit which is some distance, typically 1 metre, away.
  • the present invention seeks to overcome this problem, and in a first aspect provides a leaflet folding machine comprising a leaflet folding station and, immediately adjacent the output of that station, a leaflet rolling station comprising at least two successive pairs of rollers.
  • the leaflet rolling station is located within one folded leaflet distance from the output of the folding unit whereby leaflets are fed directly to the rolling unit after folding.
  • the rollers are preferably positioned such that the leaflet is gripped between the rollers as it exits the folding station so as to be transported through the rolling unit.
  • the rollers each pair are biased towards one another by biasing means, for example spring means.
  • biasing means for example spring means.
  • the biasing means are arranged such that the biasing force between the rollers can be varied.
  • the first, upstream set of rollers preferably acts to squeeze air out of the leaflet while the second set of rollers preferably acts to kill the creases in the leaflet.
  • the first set of rollers is subjected to a lower biasing force than the second set of rollers.
  • rollers may be made from any suitable material.
  • one roller, for example the lower roller, of each roller pair is of metal, for example steel and the other made from a plastics material.
  • a suitable plastics material is an acetal copolymer, for example Ertacetal ® .
  • the roller pair or pairs are driven from the folding station.
  • the roller station comprises a drive gear which is drivingly coupled to a suitable output drive on the folding station.
  • just one of the rollers is driven by the folding station, with the remaining roller(s) being driven by that roller through a suitable drive train.
  • rollers are provided with gear teeth which are driven by a drive belt which engages therearound.
  • roller station is provided with a belt tensioner to keep the drive belt taut.
  • a belt tensioner to keep the drive belt taut.
  • this comprises a spring biased idler wheel.
  • the tensioner comprises a further, fixed idler drive wheel around which the drive belt extends and which is positioned adjacent to the movable drive wheel.
  • rollers may be driven independently of the folding station, but their speed synchronised with that of the folding unit in any suitable manner, e.g. electronically.
  • the rolling station is formed as a unit which can be removably mounted to the folding unit so as to facilitate servicing and setting. This will also allow the unit to be used on more than one machine, if necessary.
  • the invention extends to a method of flattening a folded leaflet comprising feeding the leaflet directly from a folding station to a rolling station which is positioned less that one leaflet's length from the output of the folding station whereby the leaflet is gripped by the rolling station as or before it leaves the folding station.
  • leaflet folding unit 2 With reference to Figure 1, there is shown a known leaflet folding unit 2.
  • the particular unit shown is an FA 35/8 FL2 unit manufactured by GUK. This machine is well known in the art, and its operation will not, therefore, be described in detail here. However, suffice it so say that leaflets are folded in a predetermined manner and output in parallel rows from the unit 2. The output from the unit is referenced 4 in Figure 2.
  • roller unit 6 grasps the leaflets as they leave the folding unit output for further processing as will be described further below.
  • the roller unit 6 comprises a first pair 8 of upstream rollers and a second pair 10 of downstream rollers arranged closely adjacent to one another.
  • the roller pairs 8, 10 are arranged generally horizontally.
  • the upstream roller pair 8 comprises an upper roller 12 and a lower roller 14.
  • the downstream roller pair 10 comprises an upper roller 16 and a lower roller 18.
  • the upper rollers 12, 16 are similar in design to one another and the lower rollers 14, 18 are also similar in design to one another.
  • the rollers each have a diameter of 4 cm, although other sizes are possible.
  • the diameter is, however, small to allow the roller unit 6 to be place immediately adjacent the outlet of the folding unit 4 so that the folded leaflets can be gripped immediately by the roller unit 6.
  • the upper rollers 12, 16 are made from an acetal copolymer, Ertacetal.
  • the rollers have blind bores (not shown) at their ends to receive either a shaft or bearing for supporting the rollers in the unit.
  • the lower rollers 14, 18 are of steel.
  • the respective rollers 12, 14, 16, 18 are supported in end plates 20, 22 provided on either side of the unit 6 and separated by an upper frame 24.
  • the frame 24 is in use provided with a with a transparent cover 26 whereby the rollers of the unit 6 may be observed during operation..
  • the respective lower rollers 14, 18 are journaled in bearings 28, 30, 32, 34 in the respective end plates 20, 22.
  • the upstream lower roller is provided with an extending shaft 36 on which is mounted a drive gear 38.
  • This drive gear 38 engages with a drive 40 of the folding unit 2 (see Figure 1). This provides the drive to the roller unit 6.
  • each roller pair 8, 10 are mounted in an adjustable manner in the end plates 20, 22.
  • the end plates 20, 22 are provided with vertically extending slots 42, 44, 46, 48 in which are slidably mounted bearing supports 50.
  • Each bearing support 50 is provided with a boss on its inner face, the boss having a recess which receives a bearing which in turn receives an end portion of the respective roller 12, 16.
  • the bearing supports 50 are slidably mounted in the slots 42, 44, 46, 48 so that a biasing force on the respective roller pairs 8, 10 can be varied.
  • adjustable biasing screws 52 engage biasing springs 54 which engage an upper surface of the bearing supports 50. The pressure between the rollers of each pair can simply be varied by screwing down more or less on the respective screws 52.
  • Springs 55 are also provided under the bearing supports, the springs being located in pockets provided in the base of the slots 42, 44, 46, 48.
  • roller unit 6 is driven by a gear wheel 38 provided on one end of the lower upstream roller 14.
  • gear wheel 38 provided on one end of the lower upstream roller 14.
  • each roller is provided, at its end remote from the drive gear 38, with a drive wheel 56.
  • a drive belt 58 passes around the drive wheels 56.
  • a tensioning unit 60 is provided. This is shown most clearly in Figures 3 and 6.
  • the tensioning unit 60 comprises a support plate 62 which is movably mounted in mounting slots 64 provided in a downward extension of one of the end plates 22.
  • the support plate 62 comprises a lug 66 extending into a central slot 68 in the end plate 22.
  • the lug 66 has a vertical threaded bore for receiving a positioning screw 70 which extends into the slot 68 through the bottom of the end plate 22. After being positioned appropriately in the slot 68 by the positioning screw 70, the support plate 62 is clamped in position by clamping screws 72 which engage in threaded apertures in the support plate 62.
  • the support plate 62 mounts a fixed, toothed idler wheel 74 around which the drive belt 58 passes.
  • a further, movable toothed idler wheel 76 is mounted on one end of an L-shaped lever arm 78 the other end of which is mounted on a shaft 80 projecting from the support plate 62.
  • a tensioning spring 82 extends between respective pins 84, 86 provided on the lever arm 78 and support plate 62 respectively. This acts to pull the movable idler wheel 76 downwardly, thereby maintaining tension in the drive belt 58.
  • Folded leaflets leaving the folding unit 2 are immediately caught in the nip between the rollers of the upstream roller pair 8 as they leave the folding unit 4. This avoids the need for any transport mechanism between the two units.
  • the leaflets are caught in the nip of the downstream roller pair 10 as they leave the upstream roller pair 8.
  • the biasing force between the rollers of the upstream pair 8 is set to be less than that between the rollers of the downstream pair 10 whereby the first pair 8 act to squeeze air out of the leaflet, while the second pair act to kill the folds in the leaflet, thereby maintaining the leaflet's flatness.
  • the leaflets are driven through the roller unit 6 by frictional engagement with the rollers which are driven off the folding unit as described above.
  • the leaflets After rolling, the leaflets will be discharged either directly into a container or onto a conveyor for transportation to a packing location.
  • roller unit described can be used with any folded leaflet, such as concertina type folded leaflets. It can, however, be used with other types of folded leaflet.
