    • A stream of square folded sheets, wherein one marginal portion is thicker than the marginal portion which is parallel thereto, is fed into the nip of a rotary core and one or more flexible bands which are being convoluted onto the core whereby the sheets form a roll having convolutions which alternate with the convolutions of the band or bands. The thicker marginal portions of the sheets are fed in a direction at right angles to the axis of rotation of the core so that, in the absence of any undertaking to the contrary, the diameter of the respective end face of the roll would exceed the diameter of the other end face which is formed by the thinner marginal portions of the sheets. The development of such frustoconical roll is prevented by moving the single band or one of several bands close to that end face of the roll which is formed by the thicker marginal portions of the sheets and by maintaining the thus positioned band under requisite tension in order to compress the thicker marginal portions. The difference between the thicker and thinner marginal portions of the sheets can be monitored and the position(s) of one or more bands can be adjusted in automatic response to detection of the difference.
    • 方形折叠片材的流,其中一个边缘部分比平行于其的边缘部分更厚,被馈送到旋转芯部和一个或多个可旋转到芯上的柔性带的辊隙中,由此片材形成卷 具有与带或带的卷积交替的卷积。 片材的较厚的边缘部分沿与芯的旋转轴线成直角的方向进给,使得在没有任何相反的承诺的情况下,辊的相应端面的直径将超过直径 的另一个端面由薄片的较薄的边缘部分形成。 这种截头圆锥滚子的发展通过移动单个带或几个条带中的一个靠近由辊的较厚边缘部分形成的辊的端面并且通过将所定位的带保持在必要的张力下来防止,以便 压缩较厚的边缘部分。 可以监测片材的较厚和较薄边缘部分之间的差异,并且可以在检测到差异的自动响应中调整一个或多个条带的位置。

    • A method of manufacturing folder sheets with reinforce holes, which comprises unwinding a spindled paper band; printing predetermined graphics on the paper band; causing the paper band to go through corona treatment; applying a reinforcement strip of thermoplastic material to selected areas of the paper band; cutting the printed and partially reinforced paper band in a direction substantially perpendicular to one edge of the paper band in such a fashion as to form a plurality of paper strips each having an elongated reinforced edge area; layering and counting the paper strips until they reach a predetermined number; punching the paper strips in the reinforced edge area in accordance with a predetermined pattern; cutting the punched paper strips in a direction substantially perpendicular to the direction of the first cutting to form a plurality of folder sheets; counting and piling the folder sheets to form a block until they reach a predetermined number; and packaging and boxing the folder sheet blocks.
    • 一种制造具有加强孔的夹片的方法,包括松开卷筒纸带; 在纸张带上打印预定图形; 使纸带通过电晕处理; 将热塑性材料的加强条施加到纸带的选定区域; 以大致垂直于纸带的一个边缘的方向切割印刷和部分增强的纸带,以便形成多个每个具有细长的加强边缘区域的纸条; 分层并计数纸条直到达到预定数量; 根据预定图案在加强边缘区域中冲压纸条; 在大致垂直于第一切割方向的方向上切割冲压的纸条以形成多个折页纸; 计数和堆叠文件夹表以形成块直到它们达到预定数量; 并包装和装箱文件夹。
