    • A system is provided for processing at increased speeds a tractor-fed computer paper web (W), with nearly tensionless transport through web feeding units (B) and driving units (C) that are not speed-interdependent. For each processing cycle, the web (W) is extended without slack through an upstream lead (4) to a processing station where a certain length of the web (W) is positioned to be next processed, an excess length of loose web (6) is fed into that lead (4), forming a loop; then the certain web (W) length is processed and driven forward a distance shorter than the length of loose web (6); and then the web (W) is retracted from the upstream lead (4) to remove the residual loose web (6) and leave a next certain web length in position to be processed and delivered by way of refolding unit (D) into a pack (7) as a downstream lead of it is made slack by a web driven from the offset processing station (A).
    • 提供了一种系统,用于以提高的速度处理由拖拉机供给的计算机纸幅(W),通过卷筒纸供给单元(B)和不与速度相关的驱动单元(C)几乎无张力地传送。 对于每个处理周期,幅材(W)在没有松弛的情况下通过上游引导件(4)延伸到处理站,在所述处理站处,一定长度的幅材(W)被定位成接下来被处理,多余长度的松散幅材 )被馈送到该引线(4)中,形成一个环路; (W)长度被处理并向前驱动一段比松散网(6)的长度更短的距离; (W)从上游引线(4)缩回以去除残留的松散纤维网(6),并将下一个确定的纤维网长度留在待处理的位置并通过再折叠单元(D)输送到包装 (7)作为其下游引导件通过由偏移处理站(A)驱动的网而松弛。
