Abstract
Molding is formed by first making a longitudinally extending cut in the bottom wall of a conventional eavestrough in order to separate the eavestrough into two segments. The inner portion of the bottom wall is then attached to the exterior wall of a building beneath its eaves or elsewhere such that the back wall of the eavestrough projects outwardly. The front wall of the eavestrough is then hung from the projecting back wall so that it extends downwardly and inwardly toward the exterior wall of the building. The eavestrough is cut by means of a machine having a guide plate and a pair of cutting wheels. The guide plate has an opening of a shape similar to that of the cross-section of the eavestrough but slightly larger so that as the eavestrough is fed through the opening it is guided by the guide plate. The cutting wheels are positioned such that after the eavestrough exits from the opening, its bottom wall passes between the wheels where it is cut.
