Abstract

Le problème concernant l'invention est d'aligner et de faire concorder de manière fiable du papier incurvé sur les côtés au moyen d'une structure simple et, à partir de là, de pouvoir relier un livre sous forme d'une liasse de papier. La solution consiste en une paire gauche-droite de guides latéraux (801, 802) de section transversale en C permettant d'aligner les bords gauche-droit du papier, et qui comportent une paroi latérale (801a, 802a) qui aligne les surfaces latérales des extrémités du papier; une paroi supérieure (801b, 802b) qui aligne la surface supérieure des extrémités du papier et une paroi inférieure (801c, 802c) qui aligne la surface inférieure des extrémités du papier. Une partie saillante avant-latérale (801b1, 802b1) et une partie saillante arrière-latérale (801b2, 802b2) dans le sens du transport sont formées au niveau d'une paroi, soit de la paroi supérieure, soit de la paroi inférieure, et une partie saillante centrale (801c1, 802c1) dans le sens du transport est formée au niveau de l'autre paroi, soit de la paroi supérieure, soit de la paroi inférieure. Une rainure d'alignement (803, 804) est formée à partir de la partie saillante avant-latérale (801b1, 802b1) et de la partie saillante arrière-latérale (801b2, 802b2) d'une paroi et de la partie saillante centrale (801c1, 802c1) de l'autre paroi, et la rainure d'alignement (803, 804) peut retenir les extrémités gauche et droite du papier et les guider lors de la mise en alignement et en concordance du papier.
