Abstract

La présente invention concerne un rouleau de transport pour transporter un matériau associé à un article absorbant dans une direction de transport. La présente invention comprend : une partie de rouleau pour transporter le matériau, la partie de rouleau ayant une partie cylindrique ; et un moteur pour entraîner et tourner la partie de rouleau, au moins une partie du moteur étant logée dans un espace sur le côté périphérique interne de la partie cylindrique. Un élément de support pour porter le rouleau de transport a une surface côté avant vers un côté dans une direction CD orthogonale à la direction verticale et la direction de transport, tout en ayant une surface côté arrière vers l'autre côté dans la direction CD. La partie de rouleau est portée dans un état de support en porte-à-faux par l'intermédiaire du moteur sur la surface côté avant.
