Dans une unité de support (20) du dispositif de guidage de matériau laminé (10) : un élément de couplage (23) qui est couplé par vissage à un support de rouleau tandis qu'une direction de rotation autour d'un arbre de support de rotation (13) sur l'autre côté d'extrémité du support de rouleau (14) est utilisée comme ligne axiale, et qui peut ajuster la position de l'unité de support par rapport au support de rouleau dans la direction de rotation, une partie de coussin (26) qui peut coulisser dans la direction de rotation par rapport à l'élément de couplage, et un second élément élastique sont disposés entre l'élément de couplage et la partie de coussin de telle sorte qu'une direction d'action d'une force élastique du second élément élastique (27) coïncide sensiblement avec une direction de coulissement de la partie de coussin ; et un élément de maintien (35) comprend une partie de mise en prise (32a) qui vient en prise avec l'élément de couplage ou la partie de coussin pour limiter la quantité de saillie de la partie de coussin à partir de l'élément de couplage dans la direction de coulissement, et une vis de réglage qui ajuste la force élastique du second élément élastique (27) tandis que la partie de mise en prise vient en prise avec l'élément de couplage ou la partie de coussin.
