摘要： A shaped rubber body with improved uniformity in terms of weight and/or physical properties is produced by extruding a rubber strip by a positive displacement extruding system that includes, as seen from an upstream side of the rubber strip, a screw extruder unit, a gear pump unit and an extrusion head unit with an extrusion nozzle, which are connected in series with each other. The rubber strip is fed to a rotating support along a substantially straight passage extending from the screw extruder unit to the extrusion nozzle of the extrusion head unit, passed through a gap defined between a pair of pressure roll, and applied onto an outer surface of the support by one of the pressure rolls.

摘要： A pneumatic tire is highly precisely and efficiently manufactured by a method wherein, during formation of a green tire, at least one constitutive member, such as a sidewall (17), is formed by radially outwardly expanding a widthwise center portion of a substantially cylindrical carcass band (13), and subsequently winding an unvulcanized rubber strip and joining the rubber strip onto an outer peripheral surface of the expanded carcass band (13).

摘要： Tire rubber material is highly accurately and efficiently extruded by a positive displacement extruding system that includes, as seen from an upstream side of the tire rubber, a screw extruder unit, a gear pump unit and an extrusion head unit with an extrusion nozzle, which are connected in series with each other. While the tire rubber is caused to flow through the extruding system, the temperature of the rubber material is measured and controlled to be within a predetermined temperature range, in accordance with the measured temperature of the rubber material. The rubber material maintained at a controlled temperature is extruded from the extrusion nozzle, thereby improving the positive displacement performance of the extruding system.

摘要： The invention provides an assembly of a pneumatic tire and a rim. The tire has at least one carcass ply 2 and a belt layer 8. The ply 2 is composed of ply cords and has end portions. The belt layer 8 is composed of belt cords provided outside of the ply 2. Each belt cord extends in a direction intersecting the ply cord. Each of the end portions is held in the rim 12. The width of the tire is maximum in a circumferential cross section nullTnull with a cylindrical shape with respect to the center axis nullDnull of the tire. The cross section nullTnull extends through the rim 10. When the tire is rolled under a load and a stress is applied on the tire as an arrow nullXnull, a neighboring portion 2d near the end portions 2a, 2b is considerably bending-deformed as arrows nullYnull to absorb the stress. The roundness of the belt layer 8 is thus preserved to reduce the rolling resistance of the tire considerably.
摘要翻译：本发明提供一种充气轮胎和轮辋的组件。轮胎具有至少一个胎体帘布层2和带束层8.帘布层2由帘布层帘线构成并具有端部。带层8由设置在帘布层2的外侧的带束帘线组成。每个带束帘线在与帘布层帘线相交的方向上延伸。每个端部保持在轮辋12中。轮胎的宽度在轮胎的中心轴线“D”的圆周形状的圆周截面“T”中是最大的。横截面“T”延伸穿过轮辋10.当轮胎在负载下滚动并且在轮胎上施加作为箭头“X”的应力时，靠近端部2a，2b的相邻部分2d相当弯曲，变形为箭头“Y”以吸收应力。因此保持带层8的圆度显着降低了轮胎的滚动阻力。
