    • A paper roll braking device for rotary presses, in which a web is paid off from a paper roll supported between frames, caused to travel, and printed in a printing unit, comprising rotors provided on supporting members for supporting the paper roll, braking sections provided at a plurality of locations along the rotors and having friction discs that can engage with, or disengage from, the rotors at their respective locations, engage/disengage changeover sections for controlling the engage/disengage operation of the friction discs with respect to the rotors, and a tension sensing mechanism for sensing changes in the running tension of the web; a contact pressure adjusting section for adjusting the contact pressure of the friction discs to the rotors via the engage/disengage changeover section in accordance with the changes in running tension detected by the tension sensing mechanism, an outside diameter detecting section for detecting the outside diameter of the paper roll, and an operation control section for switching the engage/disengage changeover section as the paper roll outside diameter detected by the outside diameter detecting section reaches a predetermined diameter are provided.
    • 一种用于旋转压力机的卷筒纸制动装置,其中纸幅从支撑在框架之间的纸卷从纸张中取出并被打印在打印单元中,包括设置在用于支撑纸卷的支撑构件上的转子,设置的制动部分 在沿着转子的多个位置处并且具有可在其各自位置处与转子接合或脱离的摩擦盘,接合/分离切换部分以控制摩擦盘相对于转子的接合/分离操作, 以及张力检测机构,用于感测幅材的运行张力的变化; 接触压力调节部分,用于根据由张力检测机构检测到的运行张力的变化,经由接合/分离切换部分来调节摩擦盘与转子的接触压力;外径检测部分,用于检测 纸卷和用于切换由外径检测部检测到的纸卷外径的接合/脱离切换部的操作控制部达到预定直径。
