る輪転機新リール加速装置。 In order to match the circumferential speed of the new web with the web speed of the old web and splice them together, a device that accelerates the shaft end of the new web uses the F/V conversion value of the line speed detected by an encoder as a reel diameter signal (analog ) and the division value (quotient) thereof is a saturation value. A means for giving an acceleration command signal with a constant slope, and a V/F converted value of the acceleration command signal to the position control system of the brushless servo motor. A new reel accelerator for a rotary press, characterized in that it is equipped with means for commanding and controlling the position.
