Abstract

L'objectif de la présente invention est d'introduire sans à-coups un matériau en caoutchouc à travers un orifice de charge de caoutchouc même lorsque le matériau en caoutchouc est plus large que la largeur de l'orifice de charge de caoutchouc. Ce dispositif d'alimentation en matériau en caoutchouc 1 comprend une unité de transport 4, une unité de coupe 5 et une unité de pliage 6. L'unité de transport 4 transporte un matériau en caoutchouc G vers le côté aval à partir d'une parrtie d'extrémité avant GF. L'unité de coupe 5 coupe et sépare la partie d'extrémité avant GF du matériau en caoutchouc G qui est transportée dans une partie principale d'extrémité avant F1 d'un côté dans la direction de largeur Y et une sous-partie d'extrémité avant F2 sur l'autre côté dans la direction de largeur Y. L'unité de pliage 6 plie la sous-partie d'extrémité avant F2 pour chevaucher la partie suivante GR.
