"The top arm RT3 solves a problem prevalent in every mill: conventional top arms use setting screws for changing the distance between rollers. Manually adjusting the settings of the top arm in this way invariably leads to different distances along each ring frame. This in turn leads to uneven yarn quality. By contrast, the RT3 eliminates set screws, and therefore human error. The distance between rollers is changed by easily interchangeable, differently colored roller holders instead of set screws. In this concept, each differently coloured roller holder represents a different distance. This not only solves the problem of wrong manual distances, but also makes it easy to check the setting of each top arm by checking on the colours," Rotorcraft said in a press release. (RR)
