Abstract:
The invention relates to a cord winder (1) for a window-covering device, said cord winder including: a drum (7) for winding a cord (40), said drum being rotatable around a first rotationally symmetrical axis (A-A′); and a means (12, 13b) for guiding the cord to the winding drum, the winding drum being rotatably mounted in a holder (2). Said cord winder is characterized in that it includes a rotatable roller (14) that is mounted onto the holder along a second rotationally symmetrical axis (B-B′). Said cord winder is moreover characterized in that it includes a friction area (23) wherein at least one coil of the cord, wound onto the winding drum, is in contact with the rotatable drum.
