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