A method for binding a bundle (6) of leaves (1), where an edge (3) of the bundle (5) of leaves (1) is bound, and for the binding, use is made of a bundle (6) of leaves (1) in which the leaves (1) present a first fold line (2) that extends parallel to and at a distance (A) from the edge (3), and where the leaves (1) also present a second fold line (4) that is located parallel to and at a distance (B) from the first fold line (2), and which is located between the edge (3) and the first fold line (2).

A process for the production of multipage information leaflets or slips, the information leaflet provided with a booklet structure including two or more pages, the process including in sequence the steps of: loading and feeding of a ream of sheets printed on one or both sides, taking of a single sheet from the ream and gluing along an edge portion of the single sheet, multiple folding of the single sheet on itself along the glued portion to define a folded sheet, cutting of the folded sheet to define the multipage information leaflet with the pages connected one to the other only at a joining area in proximity of an edge, pressing of the information leaflet at the joining area, accumulation and collection of the finished information leaflets and optional rejecting of the leaflets which do not comply with the production specifications.

A fluid transference system, including: (a) at least two inflatable objects; (b) at least one variable-state fluid transfer conduit, interposed between a first and a second inflatable objects, the variable state conduit configured to allow fluid flow there-through in an open state and to disallow the flow in a closed state. A fluid transfer system, including: (a) an entry port; (b) an exit port; (c) a unidirectional main conduit defined between the entry port and the exit port; (d) an intermediate port; and (e) an intermediate conduit defined between the intermediate port and the main conduit, intersecting the main conduit between a first unidirectional valve and a second unidirectional valve, the main conduit defining a unidirectional fluid flow.

A pamphlet with a plurality of pages with a placard attached to the fold line of the pamphlet at a plurality of connection points by, staples. The placard attached to the fold line can be pivoted about the fold line to a position perpendicular or parallel to the pamphlet.

A two-sided articulating note comprises a generally flat writing portion having opposing front and back sides and a hinged edge, an anchor portion, and a joint portion between the anchor portion and the hinged edge. A method of using the note configures the note in a first configuration by securing the anchor portion to an object so that the front side of the writing portion is exposed and the back side of the writing portion faces the object while the note lies flat, writes on the front side of the writing portion while the note is in the first configuration, configures the note in a second configuration by folding over the note about the joint portion to cause the back side of the writing portion to be exposed, and writing on the back side of the writing portion while the note is in the second configuration.

Folding device to make two parallel folds in a leaf whereby the device contains two clamps with a folding edge, each formed by two clamping bars with jaws which can be moved relative to each other between an open position and a closed position and whereby the clamps to feed the leaf are arranged opposite each other with their folding edges parallel and facing each other at a distance equal to the desired distance between the folds to be made and whereby the folding device also a carrier to move the clamps in their closed position relative to each other in such a way that one of the clamps with its folding edge makes a circular movement around the folding edge of the other clamp to form both parallel folds at the folding edges of both clamps.

A folding book moves between a collapsed configuration and an expanded configuration. The book includes a book body and a plurality of layers forming the book body. Each layer moves between a folded configuration and an unfolded configuration. The folding book moves from the collapsed configuration to the expanded configuration by moving each layer of the plurality of layers from the folded configuration to the unfolded configuration in a predetermined order.

A device consisting of the combination of an outdoor field notebook and flower press having a plurality of pages for writing and a plurality of stock inserts disposed between opposing, bounded covers. The pages are adapted for writing, sketching, and general note-taking. The stock inserts provide a base for pressing organic material specimens there between. The opposing, bound covers include aligning press holes though which mating fasteners are threaded and tightened. The covers serve as the platens between which organic specimens are placed and dried for preservation.

A pamphlet with a plurality of pages with a placard attached to the fold line of the pamphlet at a plurality of connection points by, staples. The placard attached to the fold line can be pivoted about the fold line to a position perpendicular or parallel to the pamphlet.
