UNVULCANIZED BELT-LIKE RUBBER MEMBER MANUFACTURING APPARATUS AND METHOD

To provide unvulcanized belt-like rubber member manufacturing apparatus and method by which an unvulcanized belt-like rubber member, which shrinks, can be so made as to be a target length with good accuracy.SOLUTION: A front end and a rear end of a belt-like rubber member R, which is placed on a transport conveyor 2 in a flat state, is detected by a position sensor 13 over a width direction W of the belt-like rubber member R, at least one of a front end part Ra and a rear end part Rb is held by plural holding parts 8 which are juxtaposed in the width direction W, each holding part 8 is so made as to become a state that the same can be individually moved in a cross direction L by each move part 9a, and the front end part Ra and the rear end part Rb are held by a front end part holding mechanism 4 and a rear end part holding mechanism 7 respectively. An amount of movement in the cross direction L of each move part 9a is controlled by a control part 12 on the basis of detection data by the position sensor 13 and a target length G, and an extension degree in the cross direction L around a portion to be held, which is held by each holding part 8, is adjusted, and thus, the belt-like rubber member R is so made as to be the target length G.SELECTED DRAWING: Figure 10 【課題】収縮する未加硫の帯状ゴム部材を、精度よく目標長さにすることができる未加硫の帯状ゴム部材の製造装置および方法を提供する。【解決手段】搬送コンベヤ２に平置き状態で載置した帯状ゴム部材Ｒの前端および後端を位置センサ１３により帯状ゴム部材Ｒの幅方向Ｗに渡って検知し、前端部Ｒａと後端部Ｒｂの少なくとも一方を、幅方向Ｗに並列された複数の保持部８により保持し、各保持部８を各移動部９ａにより個別に前後方向Ｌに移動できる状態にして、前端部Ｒａ、後端部Ｒｂをそれぞれ、前端部保持機構４、後端部保持機構７により保持して、位置センサ１３による検知データと目標長さＧとに基づいて、制御部１２により各移動部９ａの前後方向Ｌの移動量を制御して、各保持部８によって保持されている被保持部分周辺の前後方向Ｌの伸長程度を調整して、帯状ゴム部材Ｒを目標長さＧにする。【選択図】図１０
