ABSTRACT:
A novel panel and panel assembly for use in building-type structures, together with panel forming apparatus are disclosed which are especially suitable for using portable, point-of-use, continuously operable, roll-forming techniques. The panel is characterized by upwardly diverging inclined sidewall portions (26, 27), wing portions (28, 29) of substantial lateral extent in relation to an intermediate wall portion that forms the bottom thereof, and centered edge fastening structure (31, 32). This panel provides a greater panel width per sheet stock width, ease of assembly, spacing and tracking surfaces for continuous edge seaming, and balanced strength with respect to loading. The panel assembly has continuous seam structure (54) with abutting inclined side sections (41, 47) and centered interlocking lateral flange portions (46, 53). The forming apparatus changes straight panels to curved panels and is characterized by separate, alternately operable, sidewall portion and intermediate wall portion indenting drives each having alternate idle and drive modes of operation.
