Title: Taking-up of polyester yarn
Inventor: KONDO RYOHEI
IPC: D01D7/00
Filed: 1986-05-15
Abstract: PURPOSE:To keep the taking-up tension constant by previously set-inputting the taking-up speed pattern which varies in correspondence with a prescribed variation quantity which varies with the process of taking-up operation, and controlling the number of revolution of the spindle of a winder so that the detection value of the taking-up speed coincides with said pattern. CONSTITUTION:In the taking-up operation with a low contact pressure, the rate of the slip between a bobbin 7 and a roller 8 varies as the taking-up operation proceeds. Siuce the taking-up speed is detected by detecting the number of revolution of the roller 8, the difference between the actual taking-up speed and the detected taking-up speed varies as the taking-up operation proceeds. Said difference reduces with the advance of taking-up operation, and also the taking-up tension reduces. When the actual taking-up speed is made constant, also the taking-up tension can be kept constant. Therefore, the actual taking-up speed can be kept constant with the advance of the taking-up by correcting the detection speed with the lapse of time, and the taking-up tension can be kept constant. Since the taking-up tension is proper, the winding form of the bobbin 7 is made superior.
