Method and device for applying a bead filler to a bead ring.

摘要

In manufacturing of an automobile tire, a method and a device for making a bead apex/bead ring assembly are proposed. More particularly, a method and a device for automatically applying an extruded belt-like rubber material generally referred to as "bead apex" or "bead filler" onto a core material referred to as "bead ring" which is previously mounted on a circular holding device referred to as "former" to make a bead ring/bead apex assembly are described. In the proposed method and device, the "apex" (15) is drawn out from an extruder or a roll and fed to the "bead ring" (10) and, then, it is wound around and bonded to the outer periphery of the "bead ring" (10) with rotation of the "former" (1), and at least the leading end of the apex (15) is caught and restrained by a holding device (3) during at least a period from the start to the end of the apex applying process.
