- this treatment zone T comprises two processing units, respectively U1 and U2 arranged one following each other in the direction F. Between these two units find means of training relays 16. Means 18 are also provided at the exit S of the machine.
- Figure 2 shows a blank processed by the machine from a full sheet.
- This blank 20 has cutouts 22 and folds 24 which are arranged transversely by report to the direction F of advancement of the sheet in the machine.
- Tooling of treatment units U1 and U2 located in the area T processing of the machine allow to practice these cuts and these folds.
- These tools include cutting tools or knives that form the cutouts 22 and tools to repress or pressers that form folds 24.
- the blank shown in Figure 2 also shows folds 26 which are arranged parallel to the drive direction F.
- the blank still has specific cuts, for example, openings 28 serving to form handles in packaging, which are carried out in one of the processing units U1 or U2.
- the drive means of the machine comprise drive rollers in the form of disks which are driven by rotation.
- lower drive rollers 30 and 32 at the entrance of the machine, lower drive rollers 30 and 32, and rollers higher training 34 and 36.

- the relay means 16 also include lower rollers 46 and upper 48.
- the drive means 14 and 18 each comprise two rows of lower rollers and higher. For simplicity, we have only represented one row of rollers in schematic figures 3 and 4.
- FIG. 4 shows, at the entrance, lower rollers 30 and upper rollers 34 respectively mounted on a shaft lower 31 and on an upper shaft 35.
- the lower and upper rollers 38 and 42 are mounted on two shafts 39 and 43, while the intermediate rollers 46 and 48 of the relay 16 are mounted on two shafts 47 and 49.
- the drive means are driven by a main drive motor M50.
- the different trees are connected to each other by means of transmission such as belts 51.
- rollers for training for example those at the entrance and / or exit, may not be mounted directly on their drive shafts, but be mounted on pebble supports that allow the adjustment of their respective positions.
- FIG. 3 which illustrates the kinematics of the machine represents side by side elements which, in reality, are find one above the other. We thus see side by side the lower and upper trees 31 and 35, the trees 47 and 49 and the trees 39 and 43.
- entry areas E, treatment T and output S can be located in separable modules, to which case the main motor M50 drives directly a shaft A50, by example located in the treatment area, which itself is mated by means of the Oldham joint type to driven trees A50E for the input and A50S for the output.
- Each of the processing units U1 and U2 comprises a tree carrier who is wearing a treatment tool.
- the unit U1 with its carrier shaft 52, referred to in the following carrier shaft with angular adjustment of the tool.
- This tree is located above the plane P of advancement of leaves in the machine and it cooperates, through the tools he wears, with a counterpart tree 54 located under this plane.
- This counterpart shaft carries a coating 56, for example in a material such as polyurethane, sufficiently flexible for allow tools to perform their functions, for example by folding or by cutting the leaf.
- a counterpart tree 54 ' located under the carrier shaft 62 of the processing unit U2.
- Matching trees, as well as pebbles lower drive, can be moved vertically for adapt to sheets of different thicknesses.
- Counterpart trees can be rotated in the same way as the means of training, for example to using the M50 main engine.
- they are advantageously driven by an engine M54 annex, for example an engine asynchronous with frequency converter, which is controlled for drive leaves at the same speed as the means of training, that is to say that the tangential speed of the trees of counterpart is the same as the tangential speed of the pebbles of training, despite their different diameters.
- the transverse bearing shaft 52 is rotated by a M52 shaft motor which is distinct from the engine (s) of the means training and counterpart trees. This is for example an asynchronous motor, a brushless motor, or so general, of a positioning motor.
- the shaft 52 is coupled to the output of this motor by a drive shaft 53.
- the machine comprises a UC control unit which, depending on information relating to the position of a sheet 12 in the treatment zone T, command the M52 shaft motor by a L52 command line so that, for the treatment of this sheet by a tool that carries the shaft 52, this tool is in contact with a region of the sheet and that it moves at the same speed tangential as the speed of drive of the sheet.
- a UC control unit which, depending on information relating to the position of a sheet 12 in the treatment zone T, command the M52 shaft motor by a L52 command line so that, for the treatment of this sheet by a tool that carries the shaft 52, this tool is in contact with a region of the sheet and that it moves at the same speed tangential as the speed of drive of the sheet.
- the control unit knows the speed of the means 14, 16 and 18. For example, by a line of command L50, it controls the main drive motor M50. In addition, it receives information from a speed sensor C50, for example a tachymeter in rotation with one of the trees means of training, by an information input line EL50. It can thus adjust its control of the M50 engine.
- a speed sensor C50 for example a tachymeter in rotation with one of the trees means of training
- She also knows the position of a sheet in the machine. To do this, it receives information from position sensors such as photocells C1, C2 and C3 successively arranged on the path of advancement of leaves, and which are connected to it by lines of entry LC1, LC2 and LC3 respectively.
- the sheet 12 is detected at the input by the sensor C1 and is optionally retained by a movable stop 60.
- the training of the sheet begins, that is to say that the stop 60 retracts and that the sheet is pinched between the lower and upper coaches, such as the rollers 32 and 36.
- the sensor C2 is disposed downstream of the C1 sensor, for example just downstream of the rollers 30 and 34 and detects the arrival of the sheet. This allows, if necessary, correct the speed of the M50 engine or correct the data serving when the M52 engine is actuated if, due to any slippage, the speed of displacement of the sheet between the sensors C1 and C2 is not not strictly equal to the speed of the drive means.
- control unit knows precisely the speed progress and the position of the sheet in the machine. In consequently, depending on the parameterization means MP entered in the control unit to memorize which processing (cutting, fold) should be applied to which region of the sheet, this can be control the M52 engine regardless of the means to place his tools in the right place, at the right place moment and at the right speed.
- the tool-carrying shaft 62 is referred to as the tool carrier shaft multiple.
- This shaft 62 is disposed above the plane P in the treatment area and cooperates with the counterpart shaft 54 ' similar to the shaft 54.
- the shaft 62 is rotated by a M62 engine, for example a motor similar to the M52 engine of the shaft 52 and which, as the latter is distinct from the engine (s) training means and counterpart trees.
- the M62 engine is controlled by the control unit UC, by a command line L62, to stall the speed and the position of the shaft 62 so that the tools it carries cooperate with the leaves in the right place, at the right time and at the good speed.
- the leaves are driven into the machine at a speed substantially constant drive.
- the UC control unit knowing this speed and the position of the leaf, control the M52 engine or the M62 engine between a waiting phase, in which its speed is zero or substantially zero, a phase of positioning in which his speed is different from the speed of training (she is usually superior) to come correctly position the ad hoc tool in relation to the position will reach the region of the sheet to be processed by this tool.
- the positioning phase is followed by a treatment phase in which engine M52 or M62 is controlled when this region of the leaf is next to the tree 52 or 62.
- the tangential velocity of this tool is equal to the speed of advancement to perform the desired treatment.
- a new waiting phase follows the treatment phase.
- This cycle is repeated one or more times per sheet, in function of the treatment or treatments (cuts, folds ...) to be applied.
- the motor 52 or 62 undergoes a phase of acceleration or very fast deceleration.
- the setting means correspond to a type of treatment chosen from among various possible treatments corresponding, each, to a type of packaging to manufacture (leaf size, shape of packages after folding and hanging of leaves, positioning accordingly folds and cuts).
- the angular adjustment tool carrier shaft 52 carries two tools spaced angularly. As we see better on the 7, it comprises a shaft hub 64 which is coupled to the axis 53. It also comprises a stationary tool holder 66 which is integral with the hub 64 and a movable tool holder 68 which is secured to of a mobile support 70 constituted, in this case, by one or more mobile crowns.
- Figure 7 shows the tools worn by both tool holders 66 and 68 spaced angularly from an angle ⁇ but, on Figures 1 and 8, for the convenience of drawing, these two tool holders are diametrically opposed.
- the fixed tool holder 66 is arranged according to a first G1 cylinder generator being fixed to the hub, for example by fixing and bracing shoes 72.
- the movable tool holder is fixed on the ring 70 by being arranged according to a second G2 cylinder generator.
- the tool holders 66 and 68 are arranged such that their bearing surfaces of respective tools S66 and S68 are on the same cylindrical surface.
- these surfaces S66 and S68 are projecting radially from the cylindrical surface S52 from the rest of the shaft 52, in particular determined by the crown 70. As a result, when a portion of the shaft 52 between the tool holders 66 and 68, is next to the current sheet of treatment, this portion is not in contact with said sheet, so that it is not necessary to separate the shaft 52 from the path progress of the sheet.
- the ring 70 has an internal toothing 70A on which meshes with a pinion axis 74 disposed between the hub 64 and the crowned.
- this axis is carried by a bearing 76 suitable for slide on the surface of the hub 64.
- a space 78 is provided between the outer surface S66 of the tool holder fixed and the hub 64 to allow the passage of the crown circular 70. In the present case, this annular space is made in the outer face of the shoe 72.

- This rod is movable between a locking position ( Figure 10) in which the edge 84A delimits, with the opposite edge 84B of the groove 84, a retaining profile and an unlocking position ( Figure 9) in which the edge 84A is spaced from the edge 84B to allow the setting in place of a tool in the groove.
- edge 84A is delimited by a recess made in the rod 86 and the latter rotates about its longitudinal axis between its positions of unlocking and locking.
- the retaining profile of the groove 84 may be a dovetail profile or T-profile.
- the back of the tool 88 has a fastening rib 90 having a retaining profile complementary, which can be embedded in the groove.
- the tool itself (for example formed by two 94) is carried by a plate or base 92 whose curvature delimits a cylindrical surface so that, during the rotation of the carrier shaft for processing a sheet in the machine, the distance between the tool and the plane P remains constant.
- the machine has cutting tools such as the tool 88 shown in Figures 9 to 11 which each include a portion of cutting (knives 94), and tools to push back such as the tool 88 ' of Figure 11 which each include a portion of discharge (rib 96). These tools also include a 92 base the rib 90. Once the ribs 90 inserted into the groove 84, the tools can be moved in translation to be arranged against each other. Thus, tools 88 and 88 'can be placed against the tool 88 "of Figure 11.
- the shafts 52 and 62 can each carry several tools, and can therefore be trained according to a cycle comprising a phase treatment with a first tool, a positioning phase and a treatment phase by a second tool.
- the positioning phase may simply consist of continuing to drive it at the same speed between the two phases of treatment.
- the shaft 62 also carries several spaced tools angularly, but its cylindrical surface S62 is, in the position of work, close to the plane P of advancement of the leaves.
- tools can be mounted on simple plates that are screwed in threads. radials on the cylindrical surface of the shaft 62. It can be seen in FIG. 4 that the shaft 62 bears, for example, a tool 100 having a knife for practicing orifices such as the openings 28 of the blank of FIG.

- the tree 106 extends transversely inside the zone treatment and, at each of its ends, it carries a roller 108 rotating at the first end of a connecting rod 112, the second of which end is connected to the shaft 62 by being articulated with respect to him. In this case, this connection is indirect and uses a lever 114 as shown below.
- the movable axis 110 is integral with a lever which carries a counterweight to facilitate upward movement of the bearing tree.
- each connecting rod 112 is articulated by its second end on a lever 114 having an end portion directly carries the axis 110 of the shaft 62 and whose opposite end carries a counterweight 116.
