Method of forming a laminated abutment clip

A method of forming a stamped metal laminate part from a strip stock having a generally C-shape, wherein a part carrier is provided on each side of the C-shape strip stock, wherein a longitudinal axis can be defined between the two part carriers and through the C-shape strip stock, wherein the strip stock comprises a layer of viscoelastic material laminated between two metal layers, the method comprising the steps of:

• advancing the strip stock through a progressive die to a first position at which a first form is created in the strip stock at a first location spaced from the longitudinal axis;
• thereafter, advancing the strip stock through the progressive die to a second position at which a second form is created in the strip stock by modifying the first form;
• and
• thereafter, advancing the strip stock through the progressive die to at least a third position at which a third form is created in the strip stock, wherein the second form is intermediate the longitudinal axis and the third form;
• wherein the successive creation of the first form, second form and then the third form:
• prevents the relative sliding of the metal layers in the strip stock between the longitudinal axis and the particular form being created during the formation of the successive forms, and
• permits the relative sliding of the metal layers in the strip stock at portions thereof further from the longitudinal axis than the particular form being created, thereby preventing delamination of the strip stock during the forming of the first, second and third forms.
