ABSTRACT:
A stitching apparatus for stitching tire components laid on a building drum, comprising a frame structure arranged opposingly to and spaced apart from the building drum, a central roller disposed opposingly to the mid-circumferential plane of the building drum and having a rotational axis parallel with the rotational axis of the building drum for stitching the mid-circumferential portions of the tire components on the building drum, at least a pair of side rollers circumferentially spaced apart from the central roller and arranged symmetrically to the mid-circumferential plane of the building drum for stitching both side portions of the tire components, each side roller having a rotational axis inclined to the rotational axis of the building drum and at least a surface portion made of an elastic material. The central and side rollers are alternatively projected and retracted toward and away from the circumferential surface of the building drum to stitch the tire components from their mid-circumferential portions to their both side portions.
