ABSTRACT:
An autofeed speed rivet tool and method which does not require a mandrel to be constantly withdrawn and re-stocked, is very efficient and can be used in a flow line application without requiring the line to be stopped to re-load the tool with rivets. A flexible tube carries rivets to a tool, along a guide wire. A flexible, inner tube may carry the rivets, and nylon balls may be provided on an outer tube where the nylon balls work as joints, and allow the outer tube to compress without shortening the center line. The tool may incorporate a plurality of inventive concepts, such as spoons with pivotable blades which grip the mandrel very much forward of the end of the mandrel, a transfer mechanism, rivet centering mechanisms and a mechanism for longitudinally managing the mandrel.
