An apparatus to facilitate the binding of sheets using heat activated adhesives, with the sheets having coatings that resist binding. A stack of sheets is abraded prior to binding, with the apparatus gripping the stack so that a stack end to be bound is exposed. An abrading head containing a plurality of reciprocating pins is positioned so that pins can be controlled to repeatedly strike the stack end along the length of the end. This action results in abrading the stack end thereby producing relatively long fibers from the coated sheets that absorb the binder strip adhesive thereby achieving a strong bind notwithstanding the adhesive-resistant coating.

Binding folder for binding a bundle of leaves, whereby this binding folder comprises a cover with a spine and two endpapers. In the spine a U-shaped profile from heat-conductive material is applied. The U-shaped profile comprises a base and upright arms. In the U-shaped profile a binding adhesive in the form of a hotmelt adhesive is applied. The U-shaped profile in the spine is applied by an assembly adhesive between the upright arms of the U-shaped profile and the spine of the cover. The assembly adhesive extends beyond the free edges of the upright arms and over these free edges.

Disclosed is a method for binding a bundle of leaves, of which a strip of each of the leaves is folded separately beforehand along a first line to form a first fold line that extends parallel to and at a first distance from the edge, and subsequently is folded again along a second line to form a second fold line that extends parallel to and at a second distance from the edge whereby the first distance is different from the second distance.

Binding folder for binding a bundle of leaves (2), whereby this binding folder (1) comprises a cover (3) with a spine (5) and two endpapers (6), whereby in the spine (5) a U-shaped profile (4) from heat-conductive material is applied, whereby the U-shaped profile (4) comprises a base (7) and upright arms (8) and whereby in the U-shaped profile (4) a binding adhesive (9) in the form of a hotmelt adhesive is applied, characterised in that the U-shaped profile (4) in the spine (5) is applied by means of an assembly adhesive (11) between the upright arms (8) of the U-shaped profile (4) and the spine (5) of the cover (3), whereby this assembly adhesive (11) extends beyond the free edges (10) of the upright arms (8) and over these free edges (10).

A sheet binding apparatus includes a sheet conveyer, a tape holder, and first and second rollers. The sheet conveyer is configured to convey a sheet bundle with a leading end shifted, the sheet bundle having opposing first and second surfaces. The tape holder is configured to hold a tape at a position to which the leading end reaches such that the tape adheres to the leading end. The leading end with the tape passes and is pressed between the first and second rollers. The second roller is positioned upstream in the sheet forward direction from the first roller and to face the second surface of the sheet bundle. An angle between a line perpendicular to the sheet forward direction and a line passing rotational axes of the first and second rollers is greater than 0 and less than 90.

An end paper arrangement and method for forming the front and back end paper of a book wherein the end paper arrangement comprises an inner sheet and outer sheet which are fastened on one side against each other over at least one area so that an unfastened area remains between the fastened areas. The unfastened area forms a tunnel for the spine of the book. On that side of the inner sheet which is opposite to the fastened side there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. On the side of the outer sheet which is opposite to the fastened side, there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. The method performs the assembly set forth in the arrangement.

Method for binding a bundle (5) of leaves (1) in a binding back (7), whereby the bundle (5) is placed in the binding back (7) with an edge (2) of the leaves (1) and fastened therein, characterised in that for the binding use is made of a bundle (5) of leaves (1) of which a strip (4) of each of the leaves (1) has been separately double folded beforehand along the same line to form a fold line (3) that extends parallel to and at a distance (A) from the aforementioned edge (2).

Disclosed is a method for binding a bundle of leaves, of which a strip of each of the leaves is folded separately beforehand along a first line to form a first fold line that extends parallel to and at a first distance from the edge, and subsequently is folded again along a second line to form a second fold line that extends parallel to and at a second distance from the edge whereby the first distance is different from the second distance.

A device for manufacturing a book on demand, including a cover printing or receiving station designed to respectively print or receive a cover, a body printing or receiving station designed to respectively print or receive a body, a binding station designed to join together the body and the cover, a conveyor designed and/or programmed to convey the cover and/or the body between the different stations, the device is designed to deposit glue in a gluing region on the verso of the cover inside the binding station before the cover and the body are joined together by gluing, forming a book.
