Abstract:
It is a subject to provide a method for manufacturing a tire rubber member and a pneumatic tire using the same capable of improving productivity and of accurately finishing sectional shapes. The method includes: a step of fixedly attaching winding start points 8As, 8Bs of a first rubber strip 8A and a second rubber strip 8B at positions located further inside in a width direction than respective sides e1, e2 of a rubber member R; a first winding step of forming a first layer 10 by spirally winding the first rubber strip 8A towards the one side e1 and the second rubber strip 8B towards the other side e2 up to the respective sides e1, e2; a second winding step of respectively turning the first rubber strip 8A up at the one side e1 and the second rubber strip 8B at the other side e2 so as to successively form a second layer 11 outside of the first layer 10; and a step of fixedly attaching a winding end point 8Af of the first rubber strip and a winding end point 8f of the second rubber strip to positions further inside in the width direction than the respective sides e1, e2.
Abstract:
A pneumatic tire comprises a carcass reaching a bead core of a bead portion from a tread portion via a side wall portion; a side wall rubber arranged in an outer side of said carcass and forming an outer side surface of said side wall portion; and a clinch rubber for preventing a rim displacement connected to a lower end of the side wall rubber and forming an outer side surface of said bead portion. The sidewall rubber and the clinch rubber are constituted by a strip wind body formed by winding and overlapping a side wall rubber strip and a clinch rubber strip in a circumferential direction and spirally, and the respective rubber strips are wound in the same direction from the bead portion side toward the tread portion side.
Abstract:
A pneumatic tire comprises: a carcass having a carcass main body portion reaching a bead core of a bead portion from a tread portion via a side wall portion; a belt layer arranged in an inner side of the tread portion and an outer side of the carcass; and an inner liner made of an air impermeable rubber and forming a tire cavity. A barrier rubber layer improving an adhesion property between the carcass main body portion and the inner liner is provided between the carcass main body portion and the inner liner. The barrier rubber layer is formed by winding a long barrier rubber strip around an outer peripheral surface of the inner liner wound around a drum in a circumferential direction, forming an overlapping portion, and spirally.
Abstract:
A pneumatic tire 1 having improved uniformity and durability and including a toroidal carcass 6 extending from a tread portion 2 to each of bead cores 5 in bead portions 4 through sidewall portions 3, a belt layer 7 disposed radially outward of the carcass 6 in the tread portion 2, and a cushion rubber 9 having an approximately triangular cross section disposed between the carcass 6 and each of axial edge portions 7E of the belt layer 7, and a method for producing the same, wherein the cushion rubber 9 is made from a strip laminated body formed by circumferentially and spirally winding a first ribbon-like unvulcanized rubber strip and a second ribbon-like unvulcanized rubber strip having a different composition from that of the first rubber strip.
