Definitions

  • This invention relates to a method of and apparatus for building tires, and more particularly to improvements in the method of and apparatus for building pneumatic tires by what 'is known as the flat ,band process.
  • ply material consisting of diagonally disposed parallel cords embedded in the sheet rubber, is Wrapped or placed about the substantially cylindrical outer surface of a drum or building form, and the circumferential marginal edges of the ply material are folded radially inward over the ends of the drum or form. Circular, inextensible beads are placed against the inturned edges of the ply material and the inturned edges are then folded about the beads to retain the latter in place.
  • Additional ply material is then placed or Wrapped about the iirst layer or layers of ply material on the drumvor form, to build up the body of tus for4 folding the marginal edge portions of the ply material around the inextensible beads, in which the folding action is simultaneous around the entire periphery of the edge to be folded. Improvements are also contemplated in the method of and means for supporting a bead and applying the bead to ply material carried by the form or drum.
  • the tire in a laminated construction. This addition of extra layers of the ply material may be repeated until as many laminations of the ply material have been incorporated in the body of the tire as desired.
  • the circumferential marginal edges of the layers of ply material are preferably folded about the beads so that the diagonally disposed cords embedded in the rubber of the ply material have their ends wrapped or secured around the beads.
  • the successive layers of ply material are com-v pacted or stitched together by means such as discs which are pressed against the ply material and rolled about the circumference of the drum or form, thus subjecting the ply material to localized pressure and leffecting adhesionv of the ply material layers.
  • the folding of'the marginal edges of the ply material about the beads4 is at present usually performed in a progressive manner. That is to say, one portion of a marginal edge of the ply material is folded over the bead and the folding is then continued progressively around the circumference of the band.
  • the present invention contemplates numerous improvements in both the method and apparatus for manufacturing tires. It is intended to produce tires of improved construction with a minimum of manual operation and manipulation of the material, and more quickly and at lower cost than heretofore. Particularly, the present'invention contemplates improvements in the method of and means for stitching together or compacting the successive bands or layers of ply material, and a novel method of and appara-
  • the principal object of the invention is, therefore, to provide a generally improved method of manufacturing pneumatic tires, and an apparatus for carrying out such method which is relatively simple in design and construction and produces tires rapidly and at a reduced cost.
  • the invention aims to provide a tire builder which is substantially automatic in operation and which is controlled by adjustable devices which permit alteration in the timing and sequence of the various operations and movements as desired.
