TITLE OF THE INVENTION FLEXIBLE LINK BELT, AND METHOD AND APPARATUS FOR MAKING SUCH BELTS ABSTRACT OF THE DISCLOSURE flexible link belt is made by injection molding link portions into and through a flexible carrier webbing, whereby the link portions are also bonded to each other through holes in the webbing. The injection mold used for making the links has two mold sections each with a cavity portion corresponding to the respective link portion. The carrier webbing is held in place between the two mold sections. An injection nozzle reaches into one mold portion and a movable core reaches into the other mold portion preferably in such a position that the injection nozzle and the movable core face each other across the flexible webbing. The core distributes the injected plastics material into both mold portions and so that the plastics material must move primarily through the holes or interstices in the webbing.
