Method of manufacturing tire tubes, and tire tube |
| abstract |
The object of this invention is to enable manufacture of a tube material having a thick portion for reinforcement to be efficiently carried out. The tube material 2' extrusion-molded by the extrusion molding machine has an air chamber peripheral wall 3i, a sealant chamber peripheral wall 3o and a partition wall 4. An air chamber 5 is defined between the air chamber peripheral wall 3i and the partition wall 4, and a sealant chamber 6 is defined between the sealant chamber peripheral wall 3o and the partition wall 4. On the air chamber peripheral wall 3i are protrusively formed a plurality of rib-shaped projections 15 each forming a thick portion for reinforcement. The thickness t3 of each of the projections is approximately equal to the thickness t1 of the peripheral wall 3 and the thickness t2 of the partition wall 4. It is possible to efficiently extrusion-mold the tube material 2' having the thick portions for reinforcement by thus approximately equalizing the thickness of each part of the tube material 2 including the rib-shaped projections 15. |
