摘要： A structure for starting a rotary press which is provided with a dancer roller type infeed tension control unit consisting of a dancer roller-position detector, a drag roller-speed change gear and a change gear ratio control unit, to prevent the tension of the running paper attached to a reel stand from becoming unstable (low) before and after the starting of a printing operation, and troubles, such as the waving of the running paper and the erroneous cutting of paper from occuring, the structure being characterized in that it is provided with a dancer roller stopper control unit, in which a dancer roller stopper, an element for detecting the setting and removing of a cylinder in a printing unit, and a stopper adapted to be released by a signal, which is representative of the setting of the cylinder, from the detecting element, and receive a signal, which is representative of the removal of the cylinder, therefrom are connected to a dancer roller to control the position of the dancer roller, the tension of the running paper at the starting of the rotary press being stabilized by controlling the dancer roller constantly to a neutral position.

摘要： A device for controlling tension of a rotary printing press comprises an intermediate drag presser roller (6) pressed onto the surface of an intermediate drag roller (4), a pressing device (7) which applies the force in a direction to press the intermediate drag presser roller (6), tension detectors (8), (9) to detect the tension of printed paper (1) which runs passing through a printing unit (2), and a control device (10) which controls the force of the pressing device (7) relying upon the signals from the tension detectors (8), (9). If there is any difference in the signals from the tension detectors (8), (9), the control device (10) so controls the intermediate drag presser rollers (6) via the pressing device (7) that the difference will be eliminated. Therefore, an equal tension is imparted to the paper (1) that runs passing through the printing unit (2). Namely, tension exists even at a notched portion of the printing drum, tension of the running paper varies little, and troubles are eliminated such as variation in the offset doubling and variation in the cut-off of printed matter.
摘要翻译：用于控制旋转印刷机张力的装置包括：压在中间牵引辊（4）的表面上的中间拖曳压辊（6），压制装置（7）压力辊（6），张力检测器（8），（9）以检测通过打印单元（2）运行的打印纸（1）的张力;以及控制装置（10），其控制按压力装置（7）依赖于来自张力检测器（8），（9）的信号。如果来自张力检测器（8），（9）的信号有差异，则控制装置（10）通过按压装置（7）控制中间拖拉压辊（6），以消除差异。因此，对通过打印单元（2）的纸张（1）施加相等的张力。也就是说，即使在印版滚筒的切口部分也存在张力，运行纸张的张力变化很小，并且消除了诸如印刷物的偏移加倍和偏离的变化的麻烦。
