  • the supply crew 80 and the evacuation crew 82 have been adjusted in the same way, so that the setting / removal position of the supply crew 80 to the transporter 26 is identical to the position of taking / removing the evacuation crew 82 to the carrier 28 and that the setting / removal position of the supply line 80 to the printing station 6 is identical to the position of setting / removal of the evacuation crew 82 to the printing station.
  • the operator moves, with the aid of the lever 131, the link 126 in the first groove 122 by a distance D in the direction of the axis AA relative to at the previous position of link 126 (in solid line on the figure 17 ).
  • the operator also moves with the lever 140, the link 132 in the second groove 124 by a distance E in the direction of the axis C-C relative to the previous position of the link 132.
  • the amount 116 is moved in the flange 112 to adapt the transfer device 72 to the size of the new object.
  • the displacement of the links 126 and 132 does not change the position of the first 84 and the second 86 carriages with respect to the position of the drive plate 88 and consequently the position of the feed bucket 35, when the latter is located in the object's gripping position to the conveyor 26, as well as the position of the evacuation bucket 62 when the latter is situated in the position of depositing the object to the conveyor 28.
  • the distance D ' is the distance between the previous position (in solid line) of the object being taken to the printing station of the new position (in dashed lines) of taking the object at the printing station after moving the link 126 of a distance D in the groove 122.
  • the distance D ' is equal to the distance D.
  • the distance E ' is the distance separating the previous position (in solid line) from the grip of the object to the printing station 6 along the axis CC of the new position (in dashed lines) of this object at the printing station after displacement of the link 132 in the groove 124 by a distance E.
  • the distance E ' is equal to the distance E.
  • the position of taking or removing the object to the printing station 6 can be moved in a rectangular surface height L1 length of the groove 122 and width L2 length of the groove 124.
  • the cam paths 96 and 108 have a length greater than the sweeping length of the rollers 135 and 128 since the length of these cam tracks takes into account the different possible positions of the links 126 and 132 inside the grooves 122 and 124 and the movement of and rollers 128 and 135 in the cam paths 108, 96 during the movement phases of the carriages 84, 86.
