PCT No. PCT/FI93/00034 Sec. 371 Date Aug. 23, 1994 Sec. 102(e) Date Aug. 23, 1994 PCT Filed Feb. 10, 1993 PCT Pub. No. WO93/15991 PCT Pub. Date Aug. 19, 1993A method of winding a cable on a rotating reel by way of a guide at an angle of lag which is changed at both reel flanges through a position parallel with the flange to an opposite angle of lag when a cable turn comes into contact with the reel flange. To wind the cable turns more closely together at the reel flanges, the angle of lag is changed into the position parallel with the reel flange before the cable turn comes into contact with the reel flange. A device for applying the method in a cable winding machine comprises detecting devices supposed by the guide for detecting each reel flange and for changing the angle of lag of the cable to its parallel position before reversing devices detect the reel flange and reverse the direction of displacement of the guide with respect to the reel.
