Process and apparatus for laying rubber materials for tire-constitutional members |
摘要 |
A rubber material for a tire-constitutional member is laid on a rotating support (1) with high efficiency and high accuracy by arranging a pair of rollers (11,12) rotating in opposite directions in the vicinity of a radially outer surface portion of the support and utilizing a gap (DR) defined between the rollers as a roller die. Specifically apparatus (10) for laying rubber materials for tire-constitutional members around a rotating support (1) comprises a volumetric extruder (25) for feeding an uncured rubber material onto the rotating support, a pair of rollers (11,12) located near to an outlet port of the volumetric extruder and near to a radially outer portion of the rotating support and driven in opposite directions to each other, and a gap (DR) defined between the pair of the rollers and serving as a die for the rubber material to be laid. <IMAGE> |
