Method of making integrated tie strap and rivet assemblies for saw chains |
摘要 |
Integrated tie strap and rivet assemblies for saw chains are made by the steps of rough cutting, coning, coining and trimming a length of elongate bar. The integrated tie strap and rivet assemblies thus formed replace the separate tie straps, rivets and concentric shoulders heretofore used in saw chains.
