Abstract

DC60 compressed rubber that consists of a rubber part, the first part obtained by wrapping a rubber band. one down around the axis of the tire It will sail out continuously in the direction along the periphery. circle of car tires and the second part of the rubber with different compound characteristics from the first part of the receiver and which is obtained by wrapping the second rubber band in a coil around the axis of the tire, which is wrapped outward in a direction along the rim around the circle of the tire. where the bar The first and second rubber bands each have their ends along the perimeter of the circle, and their source joins together to occur between the ends along the periphery of one side of the first rubber band. and ends along the edge around one circle of the second rubber band at least partially. This allows the first rubber band and the second rubber band to be connected to each other. Compressed rubber that consists of the first rubber part obtained by wrapping the rubber band. one down around the axis of the tire It will sail out continuously in the direction along the periphery. circle of car tires and the second part of the rubber with different compound characteristics from the first part of the receiver and which is obtained by wrapping the second rubber band in a coil around the axis of the tire, which is wrapped outward in a direction along the rim around the circle of the tire. where the bar The first strip and the second rubber band each have a tip along the perimeter around the circle and its source. A butt joint is formed between the ends along the circumference of one side of the first rubber band. and ends along the edge around one circle of the second rubber band at least partially. This allows the first rubber band and the second rubber band to be connected to each other.

Claims (8)

1. A pneumatic tire (1) is made up of a pair of bead sections (4), each with a bead core (5) located on it; a shell (16) protruding between the bead cores (15); a pair of clinch rubber components (4G), each positioned axially outward along the shell sections of each bead section; an inner rubber component (9G) positioned radially inward along the shell sections, each radially outward end of the inner rubber component of the inner rubber component connected to the clinch rubber; and an inner rubber component of a different rubber compound than the clinch rubber, in which the inner rubber component is formed by wrapping the first rubber strip (11a) in a coil around the tire core to extend in the rim direction of the tire. The rubber clinch component is formed by wrapping a second rubber strip (11b) in a coil around the axis of the tire so that it extends in the rim direction of the tire, and the first and second rubber strips, each with rim ends, which are characterized by a connecting joint (j) placed between one rim end of the first rubber strip and one rim end of the second rubber strip, at least partially so that the first and second rubber strips are continuous with each other. 2. Pneumatic tires as per claim 1, where the first and second rubber strips are wrapped in the same direction. 3. Pneumatic tires under Requisition 1 where the first and second rubber strips are wrapped in opposite directions. 4. The manufacture of pneumatic tires (1) with a pair of clinch rubber components (4G) each positioned axially outside the shell of each rim (4), and an inner radial rubber component (9G) positioned radially inside the shell, with each radial inner end of the inner radial rubber component connected to the clinch rubber and an inner radial rubber component with a different rubber compound than the clinch rubber. The procedure involves the following steps: wrapping the first rubber strip (11a) in a coil around the cylindrical body to form the inner radial rubber component; wrapping the second rubber strip (11b) in a coil around the cylindrical body in the same direction as the first rubber strip to form the clinch rubber component; and connecting one circumferential end of the first rubber strip to one circumferential end of the second rubber strip so that the ends are at least partially pressed together. 5. The method of manufacturing pneumatic tires according to claim 4, in which a second rubber strip is wrapped in the same direction as the first rubber strip, one end of the first rubber strip is the end (21a) where the wrapping is terminated, one end of the second rubber strip is the starting end (20b) where the wrapping is initiated, and the connecting procedure connects the end of the first rubber strip to the starting end of the second rubber strip. 6. The method of manufacturing pneumatic tires according to claim 4, in which a second rubber strip is wrapped in the opposite direction to the first rubber strip, one end of the first rubber strip is the end (21a) to which the wrapping is terminated, one end of the second rubber strip is the end (21b) to which the wrapping is terminated, and the connecting procedure connects the end of the second rubber strip to the end of the first rubber strip. 7. The method of manufacturing pneumatic tires under claim 4 whereby the inner rubber casing has at least one lateral edge parallel to the circumference of the cylindrical body formed by wrapping the first rubber strip continuously along the circumference of the cylindrical body for at least one full turn. 8. The method of manufacturing pneumatic tires according to claim 4, in which each clinched rubber component has at least one lateral edge parallel to the circumferential direction of the cylindrical body formed by continuously wrapping a second rubber strip along the circumferential direction of the cylindrical body at least one full turn.
