In the present invention, the drawing mechanism 102 performs intermittent setback and post-drawing processes according to the transmission speed of the scutching process equipment. The specific way of the treatment is as follows:
firstly, the traction mechanism 102 and the scutching process equipment keep the same transmission speed for synchronous transmission, so that the stability and continuity of fabric transmission are ensured, and the phenomenon that the tension on the surface of the fabric is influenced due to the asynchronous speed between the two, and the fabric is partially loosened or partially tightened is prevented.
Secondly, after the fabric is conveyed for a certain distance, the fabric may be loosened due to slippage because of the reduction of the tensile force after being conveyed for a certain distance, and the loosening may be caused by the phenomenon that the fabric is gradually loosened along with the extension of the conveying distance, so that the quality of a final product is influenced. Therefore, the transmission speed of the equipment needing the open width process is intermittently suspended, so that the possible looseness of the product in the transmission process is eliminated, and the quality of the product in the whole transmission process is stable.
Therefore, based on the above, the pause operation in the present invention is essentially the change of the transmission speed of the drawing mechanism 102 and the scutching process, i.e. when the pause is needed, the speed of the drawing mechanism 102 can be suddenly increased, and then the speed of the drawing mechanism 102 is reduced to the synchronous level, it should be noted that the displacement increment for increasing the running speed of the drawing mechanism needs to be the same as the displacement decrement for decelerating.
