Presented are a device and a method to produce helical coils from a filament (30), preferably consisting of plastic. A rotatable winding spindle (12) and an associated filament-shaping device (14, 16) are provided to wind up the filament (30) in a helical pattern, whereby the winding spindle (12) extends beyond the filament-shaping device (14, 16) in the feed direction of the filament (30) to be wound up. Viewed in the feed direction of the filament (30) to be wound onto the winding spindle (12), a pressing device (18a) is provided downstream of the filament-shaping device (14, 16) that presses the filament (30) against the winding spindle (12) and is designed to generate a predominantly adequate friction contact between the filament (30) and the winding spindle (12) so that the rotation of the winding spindle (12) essentially takes along the filament (30) into the winding direction.
