Abstract

Improved promotional pop-up designs capable of fabrication by mechanical mass production, particularly as a part of a web-press operation. A pair of pop-up elements in the form of two panels which are attached to one another, preferably by adhesive, are interconnected by hinges to basepieces that constitute the halves of a folder. Automatic web-press operation can die-cut hinge elements, either within the basepieces or within the pop-up elements in the moving web. Both pop-up elements may be formed from the sheet material located adjacent one edge of a basepiece, or the pop-up elements may be formed in flanking relation to the basepieces with one pop-up element along each lateral edge of the moving web, or they may alternate across the web.
