Abstract
A pair of angularly related interconnected steel trim elements having a mitre joint therebetween have a continuous layer of plastic material bonded upon one side of the trim elements. A corner connector reinforcement sheet of plastic material is positioned upon the plastic layer, spans the mitre joint and adjacent portions of the trim elements. A layer of adhesive upon one side of the connector sheet is in surface engagement with the plastic layer providing a rigid connection therebetween. The method of making a window frame trim assembly comprises bonding a layer of plastic material upon one side of a metallic strip, rolling its opposed longitudinal edges into transverse C-shape defining an elongated channel, cutting a series of spaced notches transversly of the channel through one edge and across to the other edge, defining a series of interconnected trim elements and successively bending adjacent trim elements into engagement closing the notches to form a series of spaced mitre joints. Additional steps include applying a layer of adhesive material to one side of a plurality of corner connector reinforcement sheet and successively applying a corner connector sheet into engagement with the plastic layer over and spanning the mitre joints and adjacent portions of the trim elements providing rigid connections at the mitre joints.
