ABSTRACT:
A housing for an air blower is assembled by providing first and second panels having respective first and second curved edges and a third panel having opposed first and second flanges. The first and second flanges define respective elongated first and second channels on opposite sides of the third panel. The third panel is wrapped around the first and second panels so that the first and second curved edges are received within the first and second channels, respectively, and the third panel spans between the first and second panels. Concurrently with the wrapping step, the first and second flanges are scored at selected intervals therealong, to secure the third panel to the first and second panel.
