  • Process for covering at least two cores with the same jacketing material
    Patent number: 5324468
    Abstract: A plurality of cores are covered with the same jacketing material by passing the cores through respective dies of a plate, while flowing the jacketing material through sub-channels in the plate and into coating relationship with the cores. Any of the sub-channels can be shut off by diverting the jacketing material a flow diverting path without affecting the flow in the other sub-channels.
