ABSTRACT:
An apparatus for building a tire comprises a supply of elastomeric sheet material of a predetermined length and having spaced apart first and second end portions. A plurality of parallel extending reinforcing members are contained in the elastomeric sheet material of which adjacent reinforcing members are spaced apart a substantially equal first distance. An embosser for elastically deforming the first and second end portions of the elastomeric sheet material increases the distance between the adjacent reinforcing members in each of the first and second end portions to a second distance greater than the first distance. A drum is provided to receive the elastomeric sheet material with the first and second end portions overlapped. A mold is provided to bond together the first and second end portions of the elastomeric material in the overlapped portion under heated pressure to form a joint. At least one reinforcing member in the first end portion is located between a pair of radially extending planes containing a respective one of a pair of adjacent reinforcing members in the second end portion.
