    • Composite filters are assembled initially by an upstream unit as groups of at least two plugs having different filtration properties. A single flow of the groups is directed from the assembling unit onto a pair of drums and divided into two flows, whereupon these are taken up by two pitch-adapting drums rotating substantially tangential one to another about parallel axes, and released to a rotating member turning on an axis normal to the axes of the drums and equipped with a plurality of carriers by which pairs of the groups are transferred from the drums to the twin channels of a garniture tongue along which two continuous rods of composite filters are formed. The carriers are equipped with an arm presenting a portion angled relative to the axis of the rotating member, so that two groups can be picked up at a time from the drums and deposited simultaneously in the channels.
    • 复合过滤器最初由上游单元组装成具有不同过滤特性的至少两个塞子组。 组的单一流动从组装单元引导到一对鼓上并分成两个流,由此这两个流被两个基本上相对于一个彼此相对于平行轴线相切地转动的螺旋适应滚筒吸收,并被释放到旋转构件 打开与滚筒轴线垂直的轴线,并配备有多个载体,通过这些载体将成对的组从滚筒转移到形成两个连续的复合过滤器杆的附属舌头的双通道。 载体配备有臂,其具有相对于旋转构件的轴线成角度的部分,使得两个组可以一次从鼓拾取并同时沉积在通道中。
