Abstract
Abstract A machine for rounding assembled wheels and for accurately forming and aligning a locating hole in the wheel spider with relation to the rim. The machine includes a plurality of radially movable rounding dies for engagement with the rim of the assembled wheel for rounding the rim. In addition, a forming tool in the form of a rotating cutter is provided for forming and aligning a locating opening in the wheel spider. The forming tool is supported by aligning means that are engageable with the rounding dies when the rounding dies are in their rounding position for accurately locating the forming tool with respect to these rounding dies.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A machine for rounding assembled wheels having a wheel center and a rum and for assuring an accurately aligned relationship between the rim and at least one opening in the wheel center which opening serves to locate the assembled wheel with respect to an associated vehicle, said machine comprising a plurality of rounding dies, means for supporting said rounding dies for movement with respect to an associated wheel, actuating means for moving said rounding dies from a retracted position wherein an assembled wheel may be juxtaposed to said rounding dies to a wheel rounding position wherein said rounding dies are adapted to engage and perform a rounding operation upon the rim of the associated wheel, forming tool means for sizing and locating at least one opening in the wheel center of the associated wheel, and aligning means for supporting said forming tool means, said aligning means being engageable with said rounding dies when said rounding dies are in their wheel rounding positions for accurately aligning said forming tool means relative to said rounding dies and to the rounded wheel rim.
Claim 2
Dependent Claim
