DRAW ROLL AND TEMPERATURE GAUGE FOR DRAW-TWISTING, DRAW-WINDING AND SPIN-DRAW-WINDING MACHINES

摘要

The draw roll is provided with a stationary temperature gauge positioned in slightly spaced relation to the inside surface of the draw roll. The temperature gauge is elongated along the middle region of the draw roll while the gap between the gauge and draw roll corresponds to the thickness of the air boundary layer which permits the most direct heat transfer. The gauge thus has a short response timelag.
