摘要： A method of forming a tire having a first and second bead on a tire building drum is disclosed. The method includes the steps of applying a green tire carcass onto the tire building drum, said tire building drum having a left and right hub, each hub having a bead pocket. The method includes the steps of placing the first and second bead onto a first and second respective bead pocket of the tire building drum and then inflating the carcass into engagement with a belt and tread package while moving at least one of the left and right hubs in the axial direction at a controlled velocity towards the other respective hub.

摘要： A method of building a tire on a second stage tire building drum is disclosed. The method employs the steps of mounting a green cylindrically shaped tire carcass onto a tire building drum so that each bead are seated in a respective bead pocket segment, inflating the carcass under low pressure and expanding the carcass into engagement with tread and belt assembly while allowing the one or more of the hubs or one or more of the bead pocket segments to freely slide in the axial direction.

摘要： A second stage tire building drum is disclosed. The tire building drum has two hubs with an inner sleeve mounted to a central shaft of the tire building drum and configured for axial movement. At least one of the hubs is configured for free axial movement. Preferably, each hub further include a sliding sleeve mounted on the inner sleeve for unconstrained sliding in the axial direction relative to the inner sleeve. Preferably, each hub has a bead receiving mechanism mounted on the sliding sleeve and comprised of one or more segments that are radially expandable. Preferably, each segment has a pocket with a curved surface for receiving a bead. The method employs the steps of mounting a green cylindrically shaped tire carcass onto a tire building drum so that each bead are seated in a respective bead pocket segment, inflating the carcass under low pressure and expanding the carcass into engagement with tread and belt assembly while allowing the one or more of the hubs or one or more of the bead pocket segments to freely slide in the axial direction.
