摘要： A damping device for a rotary offset printing machine comprises a damping or transfer roller which is immersed in a trough of damping medium and runs in contact with a drying means and a form roller contacting the plate cylinder. The damping device and the inking system of the press are mounted on a frame which is raised at the termination of operation to disengage the form roller and the inking rollers from the plate cylinder. The form roller is additionally carried on support arms which can be lowered to reengage the form roller with the plate cylinder so as to initiate washing thereof.
摘要翻译：用于旋转胶版印刷机的阻尼装置包括一个阻尼或转印辊，该阻尼或转印辊浸在阻尼介质槽中并与干燥装置接触并与接触印版滚筒的成型辊相接触。压力机的阻尼装置和上墨系统安装在框架上，该框架在操作结束时升高，以使成型辊和上墨辊与印版滚筒脱离。成型辊另外承载在支撑臂上，该支撑臂可以降低以使成型辊与印版滚筒重新接合，以便开始清洗。

摘要： A damping device for a rotary offset printing machine comprising a trough of dampening fluid in which is partially immersed a transfer roll having a hard hydrophilic surface. A wiping roll having a flexible surface is pressed against the transfer roll. In order to prevent a build-up of sludge at the inlet to the zone of contact between the two rolls, the wiping roll is rotated very slowly at a speed between one hundreth to one tenth of the speed of the transfer roll, the sludge entrained by the wiping roll being collected by a scraper blade or other means so as to prevent it being recycled.
摘要翻译：一种用于旋转胶版印刷机的阻尼装置，包括一润湿流体槽，其中部分浸渍有具有硬亲水表面的转印辊。具有柔性表面的擦拭辊被压靠在转印辊上。为了防止在两个辊之间的接触区的入口积聚污泥，擦拭辊以转印辊速度的十分之一至十分之一的速度旋转非常缓慢，污泥夹带通过擦拭辊由刮刀或其他方式收集，以防止其被再循环。
