As one of the manufacturing processes in the apparel industry, a fabric roll has to spread a piece of cloth smoothly on the working table in order to cut the cloth into parts. In this process, it is important to prevent creasing by adjusting the spreading speed of the cloth. However, the construction of a speed control system is difficult, because the tension acting on the spread cloth cannot be estimated. Accordingly, the shape of a hanging cloth-belt in the cloth spreading machine is determined by a estimated curve based on the catenary function. The coefficients of the curve are calculated by detecting the displacement of a representative point on the doth-belt. Using this estimated curve. the tension can be measured with a high accuracy without touching the cloth. In this paper. the accuracy of the calculated values by the estimated cloth curve and the dynamic behavior of the cloth-belt are discussed. A new speed control system with the estimation mechanism of tension was proposed, and good performance was confirmed.
