    • The invention provides that a vacuum drum with rows of vacuum ports over its surface is used to transport self adhesive labels from a first location at which the labels are applied (adhesive surface outwards) to the drum to a second location at which the labels are detached from the drum. The labels are held to the drum during the transport by applying vacuum to the ports until the label reaches the second location, when the first and second rows of ports at the leading edge of the label are applied with air under pressure, the pressure of the air supplied to the second row of ports being less than that supplied to the first row and slightly in advance in the time sequence, so that the edge of the label is slightly inwardly of the adjacent label extremity, initially lifted from the drum and then the extremity is blown sharply away from the drum providing effective, positive and reliable detachment of the labels from the drum.
    • 本发明提供了一种在其表面上具有一排真空端口的真空鼓,用于将标签从其上施加标签的第一位置(粘合剂表面向外)传送到第二位置,从而将标签分离的第二位置 从鼓。 标签在运输期间通过对端口施加真空而保持在滚筒上,直到标签到达第二位置时,当在标签的前缘处的第一和第二排端口被施加有压力的空气时, 提供给第二排端口的空气小于提供给第一排的空气,并且在时间顺序上稍微提前,使得标签的边缘稍微向内相邻的标签末端,最初从滚筒提起,然后 末端从滚筒急剧地吹出,从而提供标签与滚筒的有效,正确和可靠的分离。
