  • Publication number: 20110215635
    Abstract: The present invention provides an adhesive wheel balance weight capable of drastically reducing costs from those of conventional ones, and a process for producing the same. In an adhesive wheel balance weight (W) comprising a weight body (P) and an adhesive tape (T) for attaching the weight body (P) to a vehicle wheel, the weight body (P) comprises a folded weight comprising a folded metal plate piece. The folded weight of the present invention can be formed from a relatively inexpensive raw material sheet at a high yield rate. It is preferable that the raw material sheet is a zinc-coated steel sheet, because no rust-proofing aftertreatment is necessary and therefore further cost reduction is achieved, and its environmental burden is small.

  • Publication number: 20110012419
    Abstract: To provide a wheel balance weight in which a release coated paper is likely to be detached when assembling it with a wheel. A wheel balance weight according to the present invention is such that, in a wheel balance weight including: a substantially-strip-shaped weight; an adhesive-tape portion whose tape front surface is fixed to a weight rear surface; and a release coated paper covering a tape rear surface, it makes the release coated paper likely to be pinched by adjusting the widths of the adhesive-tape portion and release coated paper. Since the wheel balance weight according to the present invention is such that the release coated paper is less likely to be detached before the assembly operation and the release coated paper is likely to be pinched upon assemblage, the handling becomes easy and additionally the workability when assembling the wheel balance weight with a wheel has improved.
