Signature handling device for folding machine of offset rotary press, has signature slowing down unit including discs rotating around rotation axis, where discs are driven with constant angular velocity

The device (6) has a conveying unit (20) for conveying a signature (8) along a conveying path that defines a conveying plane (P) and a conveying direction (S). A signature slowing down unit (34) includes discs (36) rotating around a rotation axis (X-X) that carries pions (38), where the discs are driven with a constant angular velocity. The pions are moved radially from the rotation axis that is inclined to an angle higher than 75 degrees with respect to the conveying plane. An independent claim is also included for a method for folding a signature. Ce dispositif de manipulation d'une signature (8) comprend des moyens de convoyage (20) de la signature (8) définissant un plan de convoyage (P) et des moyens de ralentissement (34) de la signature. Les moyens de ralentissement (34) comprennent un élément rotatif (36) autour d'un axe de rotation (X-X) portant un organe de ralentissement (38), le premier élément rotatif (36) ayant une configuration d'engagement de l'organe de ralentissement (38) avec la signature (8), et une configuration de dégagement.L'axe de rotation (X-X) est incliné d'un angle strictement supérieur à 0 degree par rapport au plan de convoyage (P).Application aux plieuses de presses rotatives offset.
