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.

Apparatus for assembling first, second and third panels into a housing for an air blower, the first and second panels having respective first and second curved edges and the third panel having opposed first and second flanges, the first flange defining a first channel on one side of the third panel and the second flange defining a second channel on an opposite side of the third panel, said apparatus comprising:
- retaining means for retaining the first and second panels in spaced parallel relationship with the third panel below the first and second panels;
- wrapping means for wrapping the third panel around the first and second panels such that the first and second curved edges are received within the first and second channels, respectively, the first flange is in overlapping relationship with the first curved edge, the second flange is in overlapping relationship with the second curved edge and the third panel spans between the first and second panels;
- and
- securing means mounted with said wrapper means for securing said third panel to said first panel generally along said second paved edge and to said second panel generally along said second curved edge concurrently with the third panel being wrapped around the first and second panels.
A housing for an air blower, said housing comprising:
- first and second panels in generally parallel relationship, said first and second panels having respective first and second curved edges;
- and
- a third panel having opposed first and second flanges, said first flange defining a first channel on one side of said third panel and said second flange defining a second channel on an opposite side of said third panel, said third panel being wrapped around said first and second panels such that said third panel spans between said first and second panels, said first and second curved edges being received within said first and second channels, respectively, said first flange being in overlapping relationship with said first curved edge and being in pressure engagement with respective opposed sides of said first panel, said second flange being in overlapping relationship with said second curved edge and being in pressure engagement with respective opposed sides of said second panel, said first flange being scored at selected intervals therealong proximate to a distal edge of said first flange to define a first seam along which said third panel is joined to said first panel, said second flange being scored at selected intervals therealong proximate to a distal edge of said second flange to define a second seam along which said third panel is joined to said second panel.
