Abstract
Printed paper novelty items including one or more "pop-ups" and methods for making such items designed for mass production. Promotional items of this type are formed by folding a sheet material blank so that portions constituting pop-up panels are superimposed on portions constituting basepieces. Subsequent folding operation is carried out to sandwich the pop-up panels between the basepieces and to effect adhesive attachment by earlier applied adhesive patterns, and thereafter at least one of the basepieces may be cut to eliminate an original connection between it and a pop-up panel. In the final construction, the basepieces are hinged to each other along a straight line, and each of the pop-up panels is pivotally attached to one of the basepieces along a line at an angle between about 15.degree. and about 70.degree. to the hinge line. The method may be carried out as a part of an overall web press operation or may be carried out through the use of folding machines or through a combination of both.
