Draw Machine Draw Machines are designed for drawing, interlacing and sizing (if required) the warp sheet in a single, integrated process, using POY as feed stock. Thus,avoiding the draw process during the spinning, gains in production speed and in scale economies of fewer POY counts are possible. A better quality of the final warp is also a plus of the system. Rostoni provides complete lines for Draw-warping (warp knitting beams) and Draw-sizing (warp beams for weaving) as well as technological parts to fit into existing machines.
