Abstract
A method for annularly mounting a band-like filler to the outer periphery of a bead core comprises a step for attaching the filler to the outer periphery of the bead core, a step for grasping the opposite ends of the filler and separating the opposite ends of the filler from the outer periphery of the bead core, a step for sequentially attaching the opposite end surfaces of the filler to each other from the inner peripheral sections of the opposite end surfaces toward the outer peripheral sections thereof, and a step for pressing the portion of the filler, which has been separated from the outer periphery of the bead core, against the outer periphery of the bead core.
Claims3
A method for mounting a strip of a filler in an annular form onto an outer circumference of a bead core, the method comprising the steps of:
- adhering the filler to the outer circumference of the bead core with two end surfaces of the filler separated from each other;
- holding two ends of the filler and separating the two ends from the outer circumference of the bead core;
- adhering the two end surfaces of the filler to each other sequentially from their inner circumferential portions to their outer circumferential portions;
- and
- pressing a portion of the filler, which has been separated from the outer circumference of the bead core, against the outer circumference of the bead core.
A device for mounting a filler onto an outer circumference of a bead core, the device comprising:
- two pairs of jaws that respectively hold two ends of the filler, which is adhered to the outer circumference of the bead core;
- a first movement member that moves the two pairs of jaws away from the bead core and outward in a radial direction of the bead core while the two pairs of jaws are holding the two ends of the filler;
- a second movement member that moves at least one of the two pairs of jaws, which have been moved by the first movement member, toward the other pair of the jaws about a shaft located at an inner side of the filler;
- and
- a third movement member that moves the two pairs of jaws, which have been moved by the second movement member, toward the bead core.
