ABSTRACT:
An apparatus and method are provided for applying an envelope-type wrapping to tire bead rings. The apparatus and method are particularly useful when the wrapping material is to be applied directly over a lubricant coating on the bead ring. The apparatus includes a radially expansible drum, and an inflatable bladder that covers the drum and is interposed, along with the wrapping material, between the bead ring and the drum. According to the method of the invention, the bladder is inflated and rolled over in a desired sequence of steps to apply an envelope wrapping to the bead ring.
