发明名称 Folded high-profile ridge cover, and method of making
摘要 A centrally-folded and centrally-thickened ridge cover is formed from sheet shingle material by repeatedly back folding the material on itself to provide a thickened central portion for the ridge cover. The thickened central portion is disposed intermediate of a lower and an upper portion of the ridge cover. A plurality of inscribed transverse grooves are impressed into the work piece of sheet shingle material, to insure that the work piece folds at desired locations to form the back folds and thickened central portion of the finished ridge cover. A method of effecting the desired folding of a ridge cover work piece is also disclosed.
