Abstract
Apparatus, especially portable apparatus, for forming shaped edge profiles on the edges of sheet material wherein the sheet material is characterized by thickness non-uniformities; yet, wherein the root face thickness--i.e., that portion of the shaped sheet edge thickness from which no material is removed--of the shaped edge formed is maintained constant irrespective of thickness non-uniformities inherently present in such sheets. More specifically, apparatus which particularly, but not exclusively, advantageous in preparing the edges of sheet material (such, for example, as sheet aluminum) for subsequent welding operations by routing or the like, where it is critical that the root face thickness of the shaped edge remain of constant thickness irrespective of thickness variations inherently present in the sheet material itself. In one of its principal aspects, the invention relates to portable routers which permit even unskilled operators to easily and quickly form shaped edges on sheets of material on a consistently reproducible basis, yet wherein the shaped edges thus formed are characterized by a continuously presented constant root face thickness which does not vary irrespective of changes in the thickness from point-to-point on a given sheet or thickness changes from sheet-to-sheet.
