- the connecting sleeve 28 is fixed to the rotor of a drive motor 30 adapted to drive the rotor 18 relative to the frame 6 in rotation around the central axis XX.
- the folding device 2 also comprises a first folding blade 32 and a second folding blade 34 of flat products to be folded.
- the folding device 2 is provided with first displacement means 36 of the first folding blade 32 with respect to the rotor 18 between a first retracted passage position (see FIG. Figure 3 ) and a first fold out position (see Figure 5 ) passing through an intermediate position ( Figure 4 ).
- the folding device 2 is also provided with second moving means 38 of the second folding blade 34 with respect to the rotor 18 between a second retracted passage position (see FIG. Figure 3 ) and a second folding output position (see Figure 5 ).
- the folding blades 32, 34 are arranged vertically.
- the first folding blade 32 defines a first blade plane P1-P1 while the second folding blade 34 defines a second blade plane P2-P2.
- the central axis XX extends parallel to the blade planes P1-P1 and P2-P2. In addition, the central axis XX extends parallel to the transport direction T.
- the first displacement means 36 comprising a first blade holder 40 on which is fixed the first folding blade 32.
- This first blade holder 40 is rotatable relative to the rotor 18 about a first axis of rotation of the carrier. AR1-AR1 blade.
- the first blade holder 40 is housed in the rotor 18 by means of two needle bearings 42, 44 and a ball bearing 46.
- the first moving means 36 further comprises first drive means 48 of the first blade carrier 40 about the axis rotation AR1-AR1.
- the second displacement means 38 comprise a second blade holder 50 on which is fixed the second folding blade 34, this second blade holder 50 being rotatable relative to the rotor 18 about an axis of rotation AR2-AR2.
- the second displacement means 38 further comprise drive means 52 of the blade holder 50 about its axis of rotation AR2-AR2.
- the first drive means 48 are provided with a first blade holder gear 54 which is rotationally fixed relative to the first blade holder 40.
- the first drive means 48 also comprise a first intermediate gearwheel 56 ( see Figures 3 to 5 ).
- This first intermediate gearwheel 56 is rotatable about an own axis Al1-Al1 relative to the rotor 18.
- This first gear 56 meshes with a central gear 58 which is fixed coaxially with the axis XX on the frame 6 .
- the second drive means 52 comprise a second blade holder toothed wheel 60 fixedly fixed in rotation to the second blade holder 50, and a second intermediate gearwheel 62 rotatable about a second intermediate axis of rotation. AI2-AI2 with respect to the rotor 18. This second intermediate gearwheel 62 meshes with the second toothed wheel of the blade carrier 60 and with the central gear wheel 58.
- the blades 32, 34, the blade carriers 40, 50 and the intermediate gearwheels 56, 62 are uniformly distributed over the circumference of the rotor 18 around the central axis XX.
- the associated elements are located diametrically opposite one another. This arrangement leads to a dynamic equilibrium during the rotation of the rotor 18 about its axis XX.
- the first 36 and second 38 moving means are adapted to move the first 32 and second 34 folding blades synchronously between the associated retracted position and the associated output position. As shown on the Figure 5 when the first folding blade 32 is in its extended position, the second folding blade 34 is also in its extended position. Likewise, when the first folding blade 32 is in its retracted position ( Figure 3 ), the second folding blade 34 is also in its retracted position.
- This arrangement further increases the dynamic balance of the folding device 2.
- each blade 32, 34 is less than the distance between the central axis of rotation XX and the associated axis of rotation AR1, AR2.
- the folding blades 32, 34 do not touch during their rotation about their respective axis of rotation AR1, AR2.
- the folding device according to the invention operates as follows:
- the conveyor 8 conveys the signatures to fold C 1 , C 2 , C 3 on the folding table 4, and this with a frequency F.
- the blades 32, 34 are in their retracted position (see Figure 3 ) allowing the passage of the signature on the table 4.
- the rotor 18 is driven around its central axis XX by the motor 30 at a frequency which corresponds to half the frequency F.
- one of the folding blades 32, 34 pushes the signature C 1 , C 2 , C 3, C n through the opening 16 in the folding slot 14 thus folding this signature.
- the folded signature is driven by the folding rollers 10, 12 downward (see FIG. Figure 5 ).
- the rotation frequency of the rotor 18 is less than the routing frequency F of the signatures C 1 , C 2 , C 3 , C n .
- the rotational speed of the rotor 18 is 30,000 t / h.
- the rotational speed of the rotor 18 may be low.
- This second embodiment differs from that previously described by the following. Similar elements bear the same references.
- each of the folding blades 32, 34 In the folding position, each of the folding blades 32, 34 extends horizontally, and in its retracted position, each folding blade 32, 34 extends vertically.
- the folding device 2 comprises two signature supports to be folded. These supports are unrepresented tables and are of the same design as the folding table 4 with transport cords, but they are arranged vertically to receive the bending signatures horizontally. These supports replace the folding table 4 described above.
- Each of the signature media is adapted to maintain a signature in a vertical position prior to folding. The signatures to be folded are held facing each other so that the two folding blades 32, 34 can simultaneously come into contact with the associated signature C 1 , C 2 .
- the folding device further comprises two pairs of folding rollers 10A, 12A, 10B, 12B, each of which delimits a folding slot 14A, 14B.
- the folding device 2 further comprises switching means 70 adapted to switch the signatures to fold alternately to one and the other of the supports.
