摘要： A method and an apparatus for fitting bead portions of the tire onto a wheel substantially uniformly and at the same time for filling inner pressure into the tire. A wheel cap-shaped jig in the form of a disc is arranged on the side surface of the wheel. The periphery of the wheel cap-shaped jig progressively reduces outwardly in the rotating axial direction of the wheel. The tire is then obliquely arranged on the wheel through the wheel cap-shaped jig, and the bead portions are radially outwardly expanded along their circumferences so as to assemble onto the rim. An outer cylindrical member having an inclined annular end surface and an inner cylindrical member telescopically arranged in the outer cylindrical member are brought into air-tight contact with the rim and a side surface of the tire, respectively. While inner pressure is filled into the tire through the clearance between the wheel and the bead portion of the tire, the outer cylindrical member is lowered relative to the inner cylindrical member to bring the bead portions into close contact with the rim.

摘要： A method for assembling a tire on a wheel without causing any detrimental deformation of bead portions of the tire. The tire is obliquely arranged on a wheel cap-shaped jig provided on the upper side surface of the wheel located on a flat surface to arrange the lower part of the lower bead portion loosely around the wheel. The lower part of the tire is inwardly urged, while the other part of the lower bead portion is radially outwardly expanded to arrange it along its circumference around the wheel, progressively. Moreover, the part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface to arrange it loosely around the wheel. The part of the tire corresponding to the part of the upper bead portion is inwardly urged, while the remaining part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface along the circumference of the upper bead portion to arrange it around the wheel, progressively.

摘要： The magnitude of an amount of correction of unbalance at each axially opposite end face of the rim-fitted tire and the position on a circumference of each of the rim end faces are measured by means of an unbalance measuring machine for simultaneously measuring an amount of correction of static unbalance and an amount of correction of dynamic unbalance. The magnitude of the amount of correction of static unbalance, the position of an amount of correction of static unbalance on a rim periphery for minimizing a magnitude of an amount of correction of residual dynamic unbalance, the magnitude of the amount of correction of residual dynamic unbalance, and the position of the amount of correction of residual dynamic unbalance on the circumference of each of the rim end faces are calculated on the basis of the magnitude of the amount of correction of unbalance and the position of the amount of correction of unbalance on the circumference of each of the rim end faces measured. A balance weight of a magnitude corresponding to the magnitude of the amount of correction of static unbalance is fixed at the calculated position on the rim periphery, and a balance weight of a magnitude corresponding to the magnitude of the amount of correction of residual dynamic unbalance is fixed at the calculated position on the circumference of each of the rim end faces, thereby correcting weight unbalance of the rim-fitted tire.

摘要： A noise reducing apparatus in the form of a hollow body comprising two or more passage groups consisting of a plurality of passages. The length of each passage is determined such that the sound waves emitted from the passages of the adjacent passage groups form plane waves which are shifted by a half wavelength so that plane waves interfere each other. The apparatus can be secured to an opening of construction and reduce the level of sound pressure from a sound source without any closed shield construction surrounding the sound source.
