Abstract (en)
[origin: EP0768271A2] A winding machine for a continuously accumulating thread (1) has a rotatable drum (6) on which are mounted two reel spindles which can be rotated. Ahead of the drum as the thread runs, the machine also has a thread laying device (4) and a roller (5) which makes contact on its periphery with the reel (15) being formed on the operating spindle (9 or 10). The distance between the roller axis (13) and the operating spindle axis (11) can be changed in an expanding direction corresp. to the increasing reel dia. The machine has a drum rotation controller (20), a device for determining thread speed and a device for determining the rotational speed of the operating spindle. The controller has a computer unit (21) for calculating the present instantaneous dia. of the reel under formation and its present instantaneous angular speed between beginning and end of each computing cycle for use as control quantities for the drum rotation over the complete reel travel. Also claimed is a process for control of the winding machine using the above appts. where the drum is rotated with angular speed which varies continuously from one computing cycle to the next.
