  • the first transport section 16a transports the supplements packages to the second insertion station, whereas the second transport section 16b removes incomplete packages from the series of sub- sequent packages.
  • Each feeder section 8 is provided with a control mechanism giving an alert to a control computer in the case that a supplement has not correctly bee fed to the stack of supplements. In the event of a discovered failure, the computer tracing each of the packages initiates a removal of the defect package through the second transport section 16b.
  • a new package 102 arrives at the pick-up section 106 of the transport conveyor 16, as illustrated in FIG. 16a.
  • the package 104 has passed the pick up station 106 and is transported between a first support belt 108 and a top belt 105 towards the supplement insertion station.
  • the new package 102 approaching on support belt 108 is defect and has to be removed from the support belt 108.
  • Top belt rollers 120, 122 guiding the top belts 107, 105 are used to hold the packages smoothly on the support belts 108 or 116.
  • the support belt 108 and the top belts 105, 107 are sets of multiple narrow, parallel belts or ribbons, each running over a set of multiple narrow rollers 120, 122.
  • This principle is shown in FIG. 15 and also illustrated in FIG. 24, where an additional roller 120' is located next to the first support roller 120.
  • the advantage is given by the fact that a set of rollers is able to adjust to thickness variations of the packages from the centre of the package to towards the sides of the package. For example, if smaller supplements are stacked on larger supplements, the package is thinner towards the sides.
  • the multiple belt principle is useful for the supplement removal principle according to the invention as explained in the following.
  • the lifting member consists of multiple wheel segments, as illustrated in FIG. 18a. It should be mentioned at this point that also correct packages may be removed by the removing station in some instances, for example, when a supplement package is correct, but when a newspaper is missing in a pocket. Whether a newspaper is missing in a pocket is controlled by a corresponding control unit.
  • the apparatus according to the invention is configured for high speed supplement insertion. This implies that the machinery has to work smoothly and fast, because there is a risk that a slowly reacting top belt roller due to its inertia deforms the approaching stack. For this reason, the top belt rollers 120 and 122 for the top belts 107 and 105 are constructed for fast reaction as illustrated in FIG. 16 and FIG. 17.
  • Each rollers 120 has a rolling ring 133 rolling on a rotational but stationary eccentric support roller 128 combined with two lightweight arms 130a, 130b having further support rollers 131 at their ends and being in contact with the rolling ring 133. In case that a package 102 is to be rejected, and lifting member 110 is rotating upwards, as illustrated in FIG.
  • FIG. 25a and 25b A more detailed view of a further embodiment of top belt rollers 120 is illustrated in FIG. 25a and 25b.
  • This embodiment also comprises an eccentric support roller 128 on an eccentric support axis 129 and in contact with the rolling ring 133 guiding the belt 124.
  • a triangular support system is achieved inside the ring 133.
  • one of the arms in this case the upper arm 130a, is rotationally supported in a hinge 160 and can be folded away from the contact with the ring 133 such that the ring is released from the triangular support of the three rollers 128, 131.
  • the ring 133 When released, the ring 133 can be easily re- moved from the triangular support, for example to be exchanged with a different ring 133.
  • An alternative principle for the support of the ring 133 is illustrated in FIG. 24.
  • the ring 133 over which the belt 126 is moving, is likewise supported by the first support roller 128 on an eccentric support axle 129.
  • other further support rollers 131' are pro- vided on either side of the ring 133, where the ring 133 is prevented from transversal movement but can freely move about the axis of the axle 129.
  • the ring 133 is held in place against the first support roller 128 due to the tension in the belt 126.
  • the inner circumference 135 of the ring 133 is provided with a circumferential projection 137 matching a corre- sponding circumferential groove in the first support roller 128.
  • This principle of groove and projection can advantageously be used in the embodiments of FIG. 16 and 17a and b.
  • the circumferential projection can be formed as a straight projection extending at a right angle from the inner surface of the ring, by which the ring and the projection in radial cross section constitute a T-form.
  • a set of lifting members 110 on a common axle 132 is illustrated separately in FIG. 18a.
  • Using a set of lifting members is due to the fact that the support of the packages is achieved with a set of an equal number of narrow, parallel belts.
  • the lifting members 110 are, in fact, pairs of lifting sub-members 110a, 110b, as it is illustrated in FIG. 18b. The reason for this is the fact that the lifting of the roller 120 may have to be performed for two subsequent supplement packages 102, which requires a fast performance of the lifting member 110, when the machine is running at high speed.
  • the first sub-member 110a is fasted to an axle 111 such that driving the axle 111 into rotation, rotates the first sub-member HOa.
  • the second sub- member (HOb) is supported freely rotational on the axle 111 and is driven by a belt 113 from a belt drive 115.
  • a feeder station 8 is illustrated in FIG. 19-23.
  • the feeder station 8 has a feeder tray 134 in which a pile of supplements (not shown) of this feeder station 8 are supported on a row of feeder rods 136.
  • the rods 136 are moving along the underside of the stack of supplements (not shown) in the tray 134 whilst the rods 136 are rotating in order not to exert force due to friction to the underside of the supplement stack.
  • the rotation of the rods 136 is achieved by wheels 140 mounted to one end of the rods 136, the wheel 140 engaging with the lower side 142 of a rail 144 and causing the wheel 140 to rotate when the rod 136 with the wheel 140 is moved along the rail 144 during the advance of the rod 136 along the rail 144.
  • the rods 136 are carried on and advanced by a chain or belt 138 driven by a set of wheels 139. As best seen in FIG. 21, the rods 136 change orientation, once they leave the supporting space underneath the stack of supplements, before the rods return again to the underside of the stack into a horizontal orientation.
  • the advantage of using rods 136 to support the stack is the fact that supplements can be withdrawn from the stack from below.
  • Suction cups 146 on a rocker arm 148 driven by a cam wheel 159, as illustrated on FIG. 22 and FIG. 20, can move up and down and may, when correctly timed, grab the end of one supplement and move it downwards between two successively moving rods 136.
  • the rods 136 are advanced to the right, and the suction cup 146 grabs the left end of a supplements. The advance of the rods 136 then peels the supplement downwards off the stack such that the supplement is ready for stacking onto other supplements on the supplement conveyor for transport to the second insertion station.
  • a further set of grippers 150a are provided underneath the feeder tray. As illustrates in FIG. 22, these grippers are provided as four pairs of grippers 150 on two rotating wheels 152, 152'.
  • the wheels 152 take into account the motion of the rods 136 along the underside of the pile of supplements in the tray 134 such that the supplement is safely removed form the tray 134.
  • the grippers change orientation after having grabbed the front edge of a supplement, which is depicted by the two orientations 150a and 150b in FIG. 20 and FIG. 22.
