Abstract: Apparatus and a method for forming a mitered corner in an unnotched channel-shaped strip of flexible elastomeric material are provided wherein such a strip is positioned over a mandrel having a contoured portion on it in the shape of the mitered corner to be formed, the mandrel is moved against support blocks to form a bend in the strip and a loop in the side flange of the strip, hot air is forced against inside surfaces of the loop to heat the elastomeric material to a plastic adhesive state, and blades are closed against the loop of material to weld abutting surfaces together and thereafter sever excess material from the welded corner at completion of the closing of the blades.

Abstract: An arrangement and combination in which an elongated unitary gutter, fascia and soffit structure is provided in the form of a structural eave for a building, such as a dwelling house, originally constructed without the customary eave overhang. The unitary gutter, fascia and soffit structure comprises a rear wall having means for attaching the structure to the roof, a horizontal bottom wall forming the soffit, and a front wall forming the fascia, the rear, bottom and fascia walls, in turn, forming the gutter. This eave structure is attached to the roof by unitary, high strength brackets each having a main body portion extending in a vertical plane and traversing the structure, a forward end portion adapted to engage the front fascia wall of the eave, and a roof anchoring portion extending from the rear of the bracket, and integral with the main body portion. Along the front and rear edges of the soffit wall are provided elongated downwardly directed steps.
