    摘要： A rotatably supported annular tire bead is rotated by drive rollers held in contact with the inner circumferential surface of the bead, and during rotation of the bead a tape is fed and stuck onto the inner circumferential surface of the bead. The opposite side edge portions of this tape extending from this bead are stuck onto the opposite side surfaces of the bead by being pinched from the opposite sides by flange portions of the drive rollers and flange members opposed thereto, subsequently the opposite side edge portions of the tape are folded back onto the outer circumferential surface of the bead by means of scraper members, and thus the bead is perfectly covered by the tape. The above-mentioned flange members are fitted around the drive rollers so as to be slidable in the axial direction, and they are biased to reduce the intervals between the flange members and the flange portions of the drive rollers. Furthermore, there is provided expanding means for expanding the above-mentioned intervals.

    摘要： A device for automatically loading a bead core to an apparatus which associates an elastomeric filler with the bead core and for unloading the bead core with the filler.The device has two jaws for loading the bead core and means for controlling the opening of the jaws. The jaws are opened when the bead core is locked in the apparatus and the jaws are moved from the apparatus towards the loading position of a new bead core.

    摘要： A machine for spirally wrapping a continuous element, such as a cord or tape, around an annular tire bead. The machine is provided with a mechanism for holding a tire bead and rotating it in a fixed plane and at a predetermined speed, while a device with the element rotates about the rotating bead to wrap a portion of the continuous element around the bead at a speed which is correlated to the rotational speed of the tire bead so that the finished tire bead has a predetermined spiral wrap which can be varied by changing the relative rotational speeds of the tire bead and element about the tire bead. The machine is supplied with a braking mechanism which is designed to cushion the stop of the bead wrapping mechanism, rather than bringing it to an abrupt halt, and to bring the bead wrapping mechanism always to a halt at a desired position for beginning the wrapping of another bead. A knife is furnished for cutting the continuous element after the bead wrapping operation is completed and the machine is stopped. One of the cut ends of the continuous element is held adjacent the knife, thereby eliminating the need for an operator to reach into the machine to remove the loose end for wrapping around a newly positioned bead in the machine.
