Method of making a leaf rejecting rain gutter

A method of making an integrally-formed gutter system from a flat sheet of material having a first longitudinally-extending edge and a second longitudinally-extending edge for mounting under the edge of a roof of a structure, said gutter system including a trough partially covered by a shield for receiving water run-off in preference to leaves and debris, the method comprising the steps of:

• forming a first reinforcing fold-over edge along said first longitudinally-extending edge of said flat sheet of material;
• forming a shield adjacent the first reinforcing fold-over edge;
• forming a trough having a front wall adjacent the second longitudinally-extending edge of said flat sheet of material;
• and
• forming a back support wall between said shield and said trough to include a second reinforcing fold-over edge, between said back support wall and said shield, adapted to contact the structure;
• wherein said shield comprises a continuous, double-curved convolute, the curve of which extends from said back support wall, said double curve being generated upon a
• (i) first radius having its origin at the location where said trough joins said back support wall;
• and
• (ii) a second radius having a length between one-eighth and one-quarter the length of said first radius;
• said curves joining at a location where each is tangent to a common line;
• wherein said first reinforcing fold-over edge is spaced from the back support wall and closely positioned to said trough front wall;
• said first reinforcing fold-over edge and said trough front wall being straight and parallel to each other to provide an aesthetically pleasing appearance.
