我遇到一个机械领域的案子，是关于供线器的案子，其中有个句子为：
It has been noticed that there are few problems in such processing machines with a sufficient constant intake speed or with a relatively evenly intermitttent intake peed profile of the machine feed which fluctuates only to a low extent on average by time (e.g. in the case of tension or pressure spring coilers or special sequence, ring winding machines, etc) because the pay-off control can follow the demands of the processing machine sufficiently well via dancers,deflection arm and/or workpiece storage means(e.g. multiple deflections).
不理解dancers在其中的意思，求高人指点！
谢谢！ |
