Abstract: Lead weights for the balancing of automobile wheels are formed in an automatic operation. Molten lead is fed from a bath thereof to a lead weight-forming mold cavity defined by plates in edge abutting relationship and a block located in face abutting relationship with the plates and having a depression formed in the face thereof abutting the plates. The abutting edges of the plates have a groove formed therein extending the depth of the plates and defining a lead conveying passage. A weight retaining clip feed means is provided to feed individual clips from a source thereof to a holding station and clip positioning means is provided for moving individual clips from the holding station to the molding station. The plates include clip support means to support the clips at the molding station. A cutting knife is provided for removing tails from the weights after formation thereof.
