Ring spinning machine Short-Balloon Setting

cotton

Reduced yarn tension Higher spindle speed Longer traveler lifetime The new Rieter short-balloon setting for ring and compact-spinning machines helps raising the bar by balancing the various balloon forces during cop build-up, thanks to adapted hardware. Trials at spinning mills showed that this brings advantages in terms of up to 10% less ends down rates in average and longer traveler lifetime. Alternatively, the ends down rate can be kept constant, and instead the spindle speed can be increased by 3 to 6%. With an 8% longer traveler lifetime spinning mills save maintenance costs and reduce downtimes. Lower ends down rate The new short-balloon setting creates yarn balloons with shorter height and smaller diameter. This reduces the circumferential speed and thus tension peaks, and balances various balloon forces during cop build-up. As a result, less end breaks in average and a significantly lower yarn break rate at the critical cop bottom stage is possible. Various trials verify this advantage: 23% less yarn breaks in average during cop build-up and significantly lower number of yarn breaks at the cop bottom stage for a fine count yarn of 100% cotton, Ne 60, twist TM 4.2. Another trial shows a 10% reduction of yarn breaks in average, achieved for a 100% cotton (combed) yarn, Ne 30, twist TM 3.6.
