ABSTRACT:
Structure for and method of securing members of different material together. The structure includes pairs of adjustable opposed rollers through which a first and second member having different physical characteristics are guided toward deforming structure in a desired composite relation and deforming structure including opposed rollers for guiding the composite member through the deforming structure, and a rotary deforming disc having radially extending intermittent projections thereon for intermittently deforming a portion of the first member into the second member and driving the composite member through the deforming structure. The method includes moving the members in composite relation through the guide structure to the deforming structure and rotating the deforming disc to intermittently deform a portion of the first member into the second member while guiding the composite member through the deforming structure.
