Most of the drawframe autolevellers are open loop auto levellers. In open loop autolevellers, sensing is done at the feeding end and the correction is done by changing either a break draft or main draft of the drafting system, says Temesgen Regassaa, Higher Textile Engineer, ETIDI.

The Truetzschler breaker drawframe TD 9T shares a variety of technologically important elements with its trend-setting auto leveller drawframe, the TD 8.
Rieter’s drawframes, RSB-D 26 and SB-D 26, offer a number of innovations resulting in lower production costs, better sliver quality and easier operation and maintenance.
The FT6E and FT7E are driven by independent drives for the drafting system, flyers, spindles and the bobbin rail.Few machines in a modern spinning mill are as critical as the roving frame. Building a solid and reliable roving frame is not an easy task, and yet again, it is absolutely necessary for the spinner as this machine can feed, depending on the count being produced, thousands of spindles at the spinning frames.
