Les rouleaux de pliage 8,10 s'étendent chacun selon un axe central X-X et délimitent un interstice de pliage 16 entre eux. Le rouleau de pliage 8 est entraîné selon un premier sens de rotation R1 et le rouleau de pliage 10 est entraîné selon un deuxième sens de rotation R2 opposé au premier sens de rotation R1.The
Par ailleurs, la plieuse 2 comporte une butée 18 adaptée pour stopper la signature S avant son pliage.Furthermore, the folder 2 comprises a
Les cordons d'acheminement 12 sont entraînés selon un sens d'entraînement E ou sens d'acheminement s'étendant d'une entrée de la plieuse 2 vers la butée 18.The
Chaque signature S délimite un bord avant 20 dirigé vers l'aval du sens d'entraînement E ainsi qu'un bord arrière 22 dirigé vers l'amont du sens d'entraînement E.

Dans ce qui suit, les caractéristiques du rouleau de pliage 8 seront décrits, le rouleau de pliage 10 étant symétrique (voir
Le rouleau de pliage 8 comporte un premier tronçon axial 30, un deuxième tronçon axial 32, un troisième tronçon axial 34 et un quatrième tronçon axial 36.The
Le premier tronçon axial 30 comporte une première surface de pliage 40 de la signature S à plier. Cette surface de pliage 40 est une surface de cylindre partiel à section circulaire autour de l'axe central X-X.The first
Le premier tronçon axial 30 comporte en outre un dégagement auxiliaire 42 qui est radialement en retrait par rapport à la première surface de pliage 40. Ce dégagement auxiliaire 42 comporte des facettes planes. Le premier tronçon axial 30 s'étend lors du pliage au niveau du bord arrière 22 de la signature S. La jonction entre la première surface de pliage 40 et le dégagement auxiliaire 42 forme un premier bord de jonction A situé à l'extrémité aval du dégagement auxiliaire 42, vu selon le premier sens de rotation R1.The first
Le dégagement auxiliaire 42 s'étend autour de l'axe central X-X sur une plage angulaire comprise entre 120 et 160°, et de préférence comprise entre 140 et 150°.The
Le rouleau 8 est entraîné de telle manière que la première surface de pliage 40 saisisse la partie centrale 24 lorsque la lame de pliage 6 pousse la signature S dans l'interstice de pliage 16. En d'autres termes, les deux premières surfaces de pliage 40 des rouleaux de pliage 8,10 saisissent la partie centrale 24 de la signature S.The
Le deuxième tronçon axial 32 s'étend axialement de telle sorte à chevaucher le bord avant 20 lors du pliage pendant le fonctionnement de la plieuse. A cet effet, le deuxième tronçon axial 32, et donc le dégagement auxiliaire 42, chevauche axialement la butée 18.The second
Le deuxième tronçon axial 32 comporte un dégagement principal 44 qui est radialement en retrait par rapport à la surface de pliage 40 du premier tronçon axial 30.The second
Comme ceci est visible sur la
Le dégagement principal 44 s'étend autour de l'axe X-X central sur une plage angulaire comprise de préférence entre 320 et 325°. D'une manière générale, elle peut être supérieure à 270°, notamment supérieure à l'une des plages 300°, 310° et 320°, et cette plage angulaire est au maximum de 325°. La jonction entre la deuxième surface de pliage 46 et le dégagement principal 44 forme un deuxième bord de jonction B situé à l'extrémité aval du dégagement principal 44, vu selon le premier sens de rotation R1. Le premier bord de jonction A et le deuxième bord de jonction B sont circonférentiellement alignés.The
La jonction entre la deuxième surface de pliage 46 et le dégagement principal 44 forme un troisième bord de jonction C situé à l'extrémité amont du dégagement principal 44 vu selon le premier sens de rotation R1. Ce troisième bord de jonction C est circonférentiellement chevauché par la surface de pliage 40.The junction between the
La plage angulaire du dégagement auxiliaire 42 chevauche complètement la plage angulaire du dégagement principal 44 dans le sens circonférentiel autour de l'axe central X-X. En d'autres termes, les surfaces de pliage 40 et 46 sont axialement alignées. Le dégagement principal 44 et le dégagement auxiliaire 42 s'étendent ainsi sur des plages angulaires différentes autour de l'axe central X-X.The angular range of the
Le troisième tronçon axial 34 s'étend axialement entre le premier tronçon axial 30 et le deuxième tronçon axial 32. Le troisième tronçon axial 34 est muni d'une troisième surface de pliage 48 faisant tout le tour de l'axe central X-X. La troisième surface de pliage 48 a donc une forme de cylindre à section circulaire complet autour de l'axe central. La troisième surface de pliage 48 est radialement alignée avec la première surface de pliage 40. Ce troisième tronçon axial est donc adapté pour saisir la signature S sur toute sa largeur entre sa partie centrale 24 et ses bords latéraux 26.The third
Le troisième tronçon axial 34 est en outre muni de deux rainures 50, 52 faisant tout le tour.The third
Comme ceci est illustré sur la
Le quatrième tronçon 36 axial comporte une surface cylindrique à section circulaire centrée sur l'axe X-X. Le deuxième tronçon axial 32 est disposé axialement entre le quatrième tronçon axial 36 et le premier tronçon axial 30 ou le troisième tronçon axial 34.The fourth
Le rouleau de pliage 8 comporte en outre deux tourillons 60 disposés de chaque côté du rouleau.The
La plieuse 2 fonctionne de la manière suivante.Folder 2 operates in the following manner.
Les signatures S sont transportées par les cordons d'acheminement 12 jusqu'à la butée 18.The signatures S are transported by the
Lorsque la signature S atteint sa position de butée, la lame de pliage 6 pousse la partie centrale 24 à travers la fente de pliage 14 et la partie centrale 24 est saisie par la première surface de pliage 40 ainsi que par la troisième surface de pliage 48. De plus, la portion de la partie centrale 24 qui chevauche le deuxième tronçon axial 32, ainsi que la partie du bord avant 20 adjacente à la partie centrale sont saisis dans un premier temps, par la deuxième surface de pliage 46When the signature S reaches its stop position, the
Ensuite, la signature S est acheminée à travers l'interstice de pliage 16 par la première, la deuxième et la troisième surfaces de pliage jusqu'à ce que le dégagement principal 44 libère la partie du bord avant 20 de la signature à un emplacement à distance du pli formé dans la partie centrale 24. Simultanément, la première surface de pliage 40 ainsi que la troisième surface de pliage 48 poursuivent l'entraînement de la signature à travers l'interstice 16.Then, the signature S is routed through the
Lors de la poursuite de la rotation des rouleaux de pliage 8,10, les bords latéraux 26 de la signature S sont libérés au niveau du premier tronçon axial 30 par le dégagement auxiliaire 42. Ceci évite le pliage intempestif des bords latéraux, au niveau du bord arrière 22.When continuing the rotation of the
Etant donné que les rouleaux de pliage selon l'invention libèrent une grande partie du bord avant 20, ils permettent d'éviter des plissures au niveau du bord avant 20 à l'emplacement de la partie centrale 24, et ceci même à des vitesses de pliage élevées.Since the folding rollers according to the invention release a large part of the
