  • the conveying line 1 includes a pair of parallel conveying belts 11, 12.
  • the two conveying belts are located one over the other, with horizontal rotation axes.
  • the boxes to be filled are conveyed between the two conveying belts and are suitably held by a plurality of protruding lugs 13, regularly equispaced on the belts 11, 12.
  • the boxes 10 are introduced between the conveying belts 11, 12 of the conveying line 1 by a device 2, that withdraws flat folded tubular sleeves from a magazine, not shown, and erects them into boxes.
  • Respective informative sheets 3 are withdrawn one by one from a relative magazine 30 by a withdrawing device 31 and fed by a feeding line 32 to a station in which they are introduced, together with the articles, into the boxes 10.
  • the feeding line 32 includes a toothed belt 33 equipped with a plurality of spaced out pliers 34 aimed at holding informative sheets 3.
  • the belt 33 of the feeding line 32 is guided along a channel 32a integral with the stationary framework of the feeding line 32.
  • each pair of pliers 34 includes, as seen in Figure 2a, a plate 35 and a jaw 36.
  • the plate 35 is fastened to the belt 33 of the feeding line 32 by means of a counter-plate 35a, situated below,.
  • the jaw 36 is hinged to the plate 35 and rotates on a plane transversal to the movement direction of the feeding line 32, against the action of a spring 37 ( Figure 3).
  • the jaw 36 carries a transversal rod 36a, which is set parallel to the conveying line 32 and which, when the jaw is at rest position, elastically clamps the informative sheet 3 to the plate 35.
  • the jaw 36 is operated to open the pliers by a rocker arm 38, which rotates about a pivot 38a, in a plane perpendicular to the feeding line 32.
  • the rocker arm 38 is driven by an actuator 39.
  • a transversal tab folding group 4 is located and operates along the conveying line 1, together with a stationary edge 5 situated longitudinally to the same conveying line 1.
  • the task of the tab folding group 4 and stationary edge 5 is that of folding both the transversal tabs 10a, 10b of the boxes 10.
  • the transversal tab folding group 4 includes a column 40, operated by a crank mechanism 42 so that it oscillates around a vertical axis.
  • the crank mechanism 42 is operated by transmission means 43 driven by a main shaft 62.
  • the shaft 62 sets the operational relation phase of the machine.
  • a first folding member 41 protrudes in radial direction from the column 40 (see also Figure 4a).
  • a flap closing group 6 is situated downstream of the tab folding group 4, considering the movement direction A of the conveying line 1, and closes the flap 10c of the box 10.
  • the flap 10c is situated outside the tabs 10a, 10b and covers them when the box 10 is closed.
  • the second folding member 7 includes a bar 70, situated longitudinally to the conveying line 1 and operated to move vertically by an alternative actuator 71, so as to act on the flap 10c of the box 10.
  • the flap closing group 6 includes a box-like body 60, situated beside the conveying line 1.
  • a drum 61 supported so that it can rotate about an axis parallel to the conveying line 1 when driven by a suitable motor unit, through known transmission means.
  • the motor unit operates the drum via the shaft 62 that enters the body 60.
  • the opposite faces of the drum 61 feature a first radial cam 63 and a second radial cam 64, respectively.
  • Two rollers namely a first and a second roller 65, 66, are connected to levers 67, 68, first and second, respectively, and engage the radial cams 63,64.
  • the first lever 67 and the second lever 68 are pivoted to the body 60 on a pivot 69, so that they oscillate in vertical planes crosswise to the conveying line 1 ( Figures 6a and 6b).
  • a third folding member 72 including substantially a plate, which extends along the conveying line 1, is cantilevered to the first lever 67.
  • a crosspiece 73, situated along the conveying line 1, is cantilevered to the second lever 68.
  • the position of the teeth 74 is adjustable along respective slots 75 made in the crosspiece 73.
  • the drum 61 features also, on its cylindrical surface, an axial cam 76, engaged with a third roller 77.
  • the third roller 77 is supported by a carriage 78 sliding on a stem 79 longitudinally to the conveying line 1 ( Figure 7).
  • the carriage 78 forms a rack 80, which engages a pinion 81, carried inside the body 61 and rotating about a vertical axis.
  • the pinion 81 is linked to a pulley 82 outside the body 60.
  • a belt 83 is mounted on the pulley 82 and is acted upon by a pair of tightening rollers 84.
  • the opposite ends of the belt 83 are fastened to a slide 85, which has the form of a bar and is guided on the body 60, parallel to the conveying line 1.
  • the slide 85 carries a trapezoidal bar 86, aligned with the conveying line 1 movement direction.
  • the bar 86 moves between a disengaged position, in which it is displaced to protrude sidewise from the body 60, and an active position, in which it acts as a stop for the flap 10c being folded.
  • the articles and informative sheets to be introduced into the boxes are fed in time relation with the movement of the boxes 10 along the conveying line.
  • the informative sheets 3 withdrawn from the magazine 30 are transferred to the relative pliers 34 of the feeding line 32.
  • the informative sheet 3 is folded in a substantially vertical plane, longitudinally to the feeding line 32, by a stationary abutment 8 ( Figure 2c).
