FIELD: process engineering.
SUBSTANCE: invention relates to winding process, particularly, to making of electric coil. In compliance with this process, winding thread 8 is fed from feeder 7 and wound on coil carcass with out-of-round cross-section at relative displacement of winding material 8 and coil carcass. Winding material 8 is subjected to force applied across its length before application on surface to be wound. Said crosswise force is applied to winding material and varies from elastic to plastic pre-stress. Preliminary forming element is brought in interaction with winding material thread.
EFFECT: minimised barrelling of wound material.
