Abstract
A roll forming machine for a debris shedding rain gutter having a lower trough and an upper hood, wherein independent adjustments are made to the front wall of the trough to insure that its upper edge is behind the forward end of the trough. An independently adjustable kick forming station is provided to create an inward bend near the upper end of the front wall. A block is adjustably mounted to a cross-member of the machine to press the front wall inwardly to insure that the angle where the front wall joins the bottom wall of the trough is approximately ninety degrees.
