ABSTRACT:
Method and apparatus are provided for the spiral winding of a filament wherein e.g. a wire is directed by a guide plate into the spiral groove of a template and the template is rotated to wind the wire into a spiral winding. The winding is then bonded to a backer member to form a spirally wound element e.g. an electrostatic driver component in a speaker unit and the element is then separated from the template.
