Spiral wire body with controllable pattern and forming method thereof

摘要

A spiral wire body with a controllable pattern and a forming method thereof. A wire body with a throughout uniform pattern is extruded from a molding device to form a wire body having a core wire and a wrapping layer formed of two or more color plastics. The preceding segment of the wire body with the constant shape can be clipped and drawn to move by the drawing device, while the un-cooled wire body extruded from the molding section can be twisted in the rotation area by the rotation of the rotation device into the wire body which the surface thereof has a spiral pattern. The spiral patterned wire body then is cooled down through a cooling device so as to form the wire body with a final constant shape in which the surface of the wrapping layer is formed with a controllable spiral pattern.
