Publication number: 20110215635Abstract: 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.Type: ApplicationFiled: August 10, 2010Publication date: September 8, 2011Applicant: Toho Kogyo Co., Ltd.Inventors: Yutaka Yamaguchi, Osamu Yamaguchi
