Abstract
A method of making a pop-up device for a card, book, novelty, or the like with a sandwich-like structure including a base or back (300), a front or cover (200), and a tongue (130) disposed between. All three sections may be of equal length. The three sections are folded onto one another and glued to make the sandwich. The tongue has a protruding tab end (135) for a user to pull; the end distal the tab end is fastened to a portion of the cover. A pull-slot (325) cut out between the cover and back guides the tongue for pulling to eliminate shims. The cover is slit by two parallel cuts (210) and three crosswise creases. The cuts are parallel to the tongue. The creased portion of the cover pops up when the tongue is pulled by a user. The fold lines are perpendicular to the direction of the tongue movement.
Claims13
A method of making a pop-up, comprising:
- providing a blank having a blank length and edges separated by a blank width,
- the blank including a tongue at a first end and a pull-slot intermediate the tongue and a second end, the pull-slot having a pull-slot width less least equal tk width and at least equal to a tongue width;
- creasing a pop-up portion of the blank intermediate the tongue and the pull-slot;
- folding the tongue onto a second section of the blank about a first fold line in a first sense of rotation, the first fold line separating the second section from a first section of the blank, the first fold line being angled to the length such that the tongue aligns with the pull-slot;
- folding a third section of the blank onto the second section about a second fold line in a second sense of rotation;
- fastening the second section to the third section proximal the edges;
- and
- providing slide means for slidably holding a base end of the tongue, proximal the first fold line, adjacent the third section.
