Abstract

La présente invention concerne une structure permettant de soulever des ébauches qui utilise un dispositif de soufflage à deux étapes. La structure comprend une bande transporteuse servant à acheminer les ébauches et une autre bande opposée servant à les retirer. Sur un côté de l'entrée de la bande transporteuse de retrait se trouve une protection des ébauches entraînée par un cylindre et sous laquelle est placé un support d'ébauches également entraîné par ledit cylindre. L'orientation des ébauches en forme de bouteille servant de support est perpendiculaire à la direction que suivent les ébauches. En face du support se trouve un système de réglage. Le cylindre, le support et le système de réglage sont reliés à une structure tournant sur 180° susceptible de se loger dans une surface verticale. Un côté de la structure rotative présente une plaque de compression des ébauches entraînée par le cylindre. L'orientation des ébauches de support perpendiculairement à la direction de déplacement des ébauches en forme de bouteille se traduit par un gain d'espace, un volume sensiblement plus important des ébauches sur la chaîne d'apport thermique, et une efficacité thermique accrue. Par ailleurs, la structure de l'invention permet de retirer directement les ébauches de la bande transporteuse et de diminuer la durée d'élaboration des ébauches.
