Abstract: An end-configuration of components to be moved or positioned is first obtained. This end-configuration determines the relative positioning and orientation of the components with respect to each other when in a final, desired configuration. A folding pattern is then obtained that is formed by interior vertices defining corresponding tessellation facets. The folding pattern can be induced to transition from a first folded configuration to a second folded configuration. When in the second folded configuration mounting facets, which are a subset of the tessellation facets, are arranged by the geometry of the folding pattern into positions and orientations with respect to each other that correspond to the end-configuration of the components. A foldable structure is then obtained that folds in accordance with the folding pattern, and the components are affixed to their respective mounting facets.

Abstract: Apparatus and method for conditioning an edge of a sheet to be bound so that the edge is conducive to accepting heat activated adhesives used in conventional binding. The sheet is first bent in one direction to form a folding line, with the fold line being a short distance from the edge of the sheet to be conditioned and with that distance being determined primarily by the thickness of the sheet. The bend in the sheet is typically 90 degrees, with the radii of curvature of the opposite sheet surfaces at the fold line being unequal so that a shear force is applied near the sheet end thereby tending to tear or fracture in interior of the sheet near the end. Typically the sheet is then bent in an opposite direction along the folding line so as to produce an opposite shear force that reinforces the creation of tears and fractured in the sheet.

Abstract: Tab material which is wrapped tightly around an edge of a sheet is adhered flat to both faces of the sheet. The sheet is passed through a printer, and indicia is printed on both sides of a tab material fold line on at least a portion of the tab material on one of the faces.

Abstract: Two movable members, one on either side of a pre-folded continuous form entering a paper stacking area, are driven according to a determined position of the pre-folded form to push a leading edge of the form to one or another side of the stacking area so that the folds in the form will develop correctly in a stack. Only one of the members is permitted to contact the form at any time, and the members are separated by a sufficient angle so that no position of the members permits both members to contact the form. After directing the first and second sheets of the form, the members return to a home position in which neither member obstructs or interferes with subsequent stacking of the form. The position of the pre-folded form may be determined by a leading edge sensor, by a sheet feed rate sensor, by a fold position sensor, by a fold orientation sensor, by timing from a predetermined position, or by manual input.
