An apparatus and method for removing an unvulcanized tire tread from a storage device (14) includes the step of inverting the tread (12) and transporting it to a roller conveyor in a single step. The tread (12) is picked up by a vacuum bar (80) fitted with a series of suction cups (76). Individual suction cups (76) can be selectively supplied with vacuum depending on the length of the tread (12). After the suction cups (76) have engaged the tread, the tread is raised from the storage device (14), inverted through 180 degrees, and then set onto a special slotted roller conveyor (130). The slotted roller conveyor (130) has a center slot (142) to receive the vacuum bar (80) as it passes therethrough. Side slots (144, 146) in the conveyor receive arms (90, 92) attached to the vacuum bar (80).

L'invention concerne un procédé et un dispositif permettant de sortir une bande de roulement non vulcanisée d'une unité de stockage (14). Selon le procédé, la bande (12) est retournée et amenée à un convoyeur à rouleaux en une seule étape. La bande de roulement (12) est soulevée par une barre d'aspiration (80) portant une série de ventouses (76). L'aspiration amenée aux différentes ventouses (76) peut varier en fonction de la longueur de la bande (12). Une fois que les ventouses (76) sont entrées en contact avec la bande de roulement, celle-ci est soulevée du dispositif de stockage (14), retournée de 180·, puis placée sur un convoyeur à rouleaux à fentes spécial (130) qui comporte une fente centrale (142) destinée à recevoir la barre d'aspiration (80) lorsque celle-ci la traverse. Des fentes latérales (144, 146) creusées dans le convoyeur reçoivent des bras (90, 92) fixés sur la barre d'aspiration (80).
