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