The application is mainly to small DC machine armature windings made up in the form of a cylinder, wound round a former, from a continuous winding wire. The former (2) has guide strips (4) exactly 180 deg. electrical apart. It is placed at an angle to the horizontal and can be rotated. Around it revolves the wire feed (5, 6, 7) on a vertical axis. The wire (8) is thus applied to the former tangentially as the feed rotates, and its direction is abruptly reversed each time it hooks round one of the guides (4). These may be insulation strips which ultimately remain in the coils. By advancing the cylinder (2) by a step equal to the wire thickness a two layer winding of two conductors depth is formed.
