  • Patent number: 4457561
    Abstract: A cover of moulded plastics material for fitting to a pressed steel motor car wheel to simulate in a realistic manner a wire spoked wheel comprises two separate, but individually integral, injection mouldings 1, 2 of plastics material. The part 1 comprises an inner hub part 3, an inner rim part 5 and a series of spokes 8 extending between and integrally moulded with the parts 3 and 5. The other part 2 comprises a hub part 11, a rim part 12 and a series of spokes 15 extending between and integrally moulded with the parts 11 and 12. Owing to the moulding of the cover in two separate parts which fit together co-axially, it is possible to make the cover with the spokes 8 and 15 lying in a number of axially separated planes while still forming the moulds from the which the parts 1 and 2 are produced in such a way that there are no undercuts and the mouldings can easily be removed from the moulds.
