1509265 Moulding an integral tyre and wheel MONSANTO CO 4 July 1975 [5 July 1974] 28212/75 Heading B5A [Also in Division B7] An integral tyre and wheel composed of mouldable elastomeric polymeric material having a Young's modulus of 800-1250 kg./sq. cm. (see Division B7), may be prepared by injection compression or rotational moulding. For example, the mould illustrated may be used to make two identical parts which are joined to form the integral tyre and wheel. Alternatively, the tyre and wheel may be formed by joining matching surfaces of non-identical parts. |
