Provided is a method and apparatus for molding and winding in a continuous operation a string of molded items. The molded items of the string or chain are molded in spaced relationship to one another and are connected by molded scrap connectors. The string of molded items is then advanced until only a trailing connector of the last molded item extends into the mold cavity. Upon subsequent molding operation, therefore, the subsequent molded item is molded integral with the existing string of molded items. The continuous string of molded items is kept under constant tension and wound periodically into a coil. The molding, advancing, tensioning and winding operations are all integrated and synchronized in order to provide a wound package which greatly facilitates its use in an automatic assembly operation. The synchronization of the molding, advancing, tensioning and winding operations also provide for an overall smooth and integrated system for forming the wound coils of molded items, which system can be run continuously with little supervision.
