What does a Tire Builder do?
Operate machines to build tires.
- Depress pedals to rotate drums, and wind specified numbers of plies around drums to form tire bodies.
- Start rollers that bond tread and plies as drums revolve.
- Activate bead setters that press prefabricated beads onto plies.
- Inspect worn tires for faults, cracks, cuts and nail holes, and to determine if tires are suitable for retreading.
- Cut plies at splice points, and press ends together to form continuous bands.
- Align treads with guides, start drums to wind treads onto plies, and slice ends.
- Position rollers that turn ply edges under and over beads, or use steel rods to turn ply edges.
- Position ply stitcher rollers and drums according to width of stock, using hand tools and gauges.
- Build semi-raw rubber treads onto buffed tire casings to prepare tires for vulcanization in recapping or retreading processes.
- Wind chafers and breakers onto plies.
- Pull plies from supply racks, and align plies with edges of drums.
- Roll camelbacks onto casings by hand, and cut camelbacks, using knives.
- Clean and paint completed tires.
- Fit inner tubes and final layers of rubber onto tires.
- Rub cement sticks on drum edges to provide adhesive surfaces for plies.
- Fill cuts and holes in tires, using hot rubber.
- Brush or spray solvents onto plies to ensure adhesion, and repeat process as specified, alternating direction of each ply to strengthen tires.
- Roll hand rollers over rebuilt casings, exerting pressure to ensure adhesion between camelbacks and casings.
- Measure tires to determine mold size requirements.
- Depress pedals to collapse drums after processing is complete.
- Trim excess rubber and imperfections during retreading processes.
- Place tires into molds for new tread.
