Abstract
Various embodiments relate to a pivoted dual roller tire sidewall and body ply stitching apparatus for stitching tire components, the apparatus including a first roller having a toroidal shape and connected to a first supporting arm, a second roller having a toroidal shape and connected to a second supporting arm and a supporting member connected to the first roller, the second roller and a third supporting arm wherein the second supporting arm is longer than the first supporting arm and the first roller and the second roller are configured to pivot on the supporting member.
Claims9
A dual roller tire sidewall and body ply stitching apparatus for stitching tire components, the apparatus comprising:
- a first roller having a toroidal shape and connected to a first supporting arm;
- a second roller having a toroidal shape and connected to a second supporting arm;
- a third supporting arm between the first supporting arm and the second supporting arm;
- and
- a supporting member connected to the first supporting arm, the second supporting arm, and the third supporting arm, wherein
- the second supporting arm is longer than the first supporting arm,
- the supporting member connected to the first supporting arm and the second supporting arm is configured to pivot about the third supporting arm,
- the supporting member includes a first semicircular hole and a second semicircular hole,
- the first supporting arm is removably inserted into the first semicircular hole and the second supporting arm is removably inserted into the second semicircular hole;
- and
- an overlap between the first roller and the second roller is based on respective lengths of the first supporting arm and the second supporting arm, wherein a size of the overlap is adjustable by varying the lengths of the first and second supporting arms.
A method for stitching tire components using a dual roller tire sidewall and body ply stitching apparatus, the method comprising the steps of:
- stitching, by a first roller having a toroidal shape and connected to a first supporting arm, the tire components, and
- stitching, by a second roller having a toroidal shape and connected to a second supporting arm, the tire components, wherein
- a supporting member is connected to the first supporting arm, the second supporting arm, and a third supporting arm between the first supporting arm and the second supporting arm;
- the second supporting arm is longer than the first supporting arm,
- the supporting member connected to the first roller and the second roller is configured to pivot about the third supporting arm
- the supporting member includes a first semicircular hole and a second semicircular hole,
- the first supporting arm is removably inserted into the first semicircular hole and the second supporting arm is removably inserted into the second semicircular hole, and an overlap between the first roller and the second roller is based on respective lengths of the first supporting arm and the second supporting arm, wherein a size of the overlap is adjustable by varying the lengths of the first and second supporting arms is removably inserted into the second semicircular hole.
A dual roller tire sidewall and body ply stitching apparatus for stitching tire components, the apparatus comprising:
- a first roller connected to a first supporting arm, the first roller having a toroidal shape and a first peripheral edge;
- a second roller connected to a second supporting arm, the second roller having a toroidal shape and a second peripheral edge, wherein the second peripheral edge overlaps the first peripheral edge by an overlap distance of zero to one half of a width of the first roller, and
- a supporting member which is:
- removably connected to the first supporting arm,
- removably connected to the second supporting arm, and
- connected to a third supporting arm,
- wherein the supporting member is configured to pivot about the third supporting arm,
- wherein the overlap distance is adjustable by varying the lengths of the first and second supporting arms.
