Embodiment Construction

[0031] figure 1 The plant 1 shown in substantially comprises two conveyor belts 2 positioned next to each other.

[0032] The conveyor belts 2 are of the "endless" type, which means that they are endless and are attached around two counter drums 3 or counter wheels.

[0033] The conveyor belt 2 is made of metal such as steel.

[0034] Preferably, the conveyor belt 2 has a maximum thickness of 0.4 mm, preferably a maximum thickness of 0.2 mm. In this case, the thickness of the conveyor belt is 0.2 mm.

[0035] The device 1 is also provided with feeding means 4 for introducing book pages 5 between the conveyor belts 2 . These pages 5 can be paper pages 5, but also pages 5 made of (thin) cardboard, plastic or the like.

[0036] The book pages 5 may or may not have printed matter, such as text, photographs, pictures and the like.

[0037] Since the conveyor belts 2 are positioned against each other, parts of the pages 5 other than the strip 6 protruding between the conveyor b...

Abstract

Device for double folding leaves, characterised in that the device (1) is provided with two conveyor belts (2) that are located against one another such that leaves (5) can be clasped between the conveyor belts (2) with the exception of a strip (6) that protrudes between the conveyor belts (2), whereby the conveyor belts (2) are aligned with respect to one another along the side of the strip (6) and with two or more folding elements (1, 8) along the conveyor belts (2) that can fold the aforementioned strip (6), whereby the device. (1) is equipped such that leaves (5) are guided with their strip (6) alongside the folding elements (7, 8) by the driving of the conveyor belts (2), whereby at least one folding element (7, 8) folds the strip (6) in one direction and at least one folding element(7, 8) folds the strip (6) in the other direction.

Description

technical field [0001] The invention relates to a device for bidirectional folding of book pages. [0002] More particularly, the invention aims at realizing pages in which a strip of pages is double-folded along the same straight line, wherein these pages are used for books or documents whose pages can be laid flat. Furthermore, any printed matter can continue seamlessly across the two pages that are opened. This is particularly ideal for editing of photo books, magazine books and similar books with photos and illustrations that continue across the full width of the opened book. Background technique [0003] Two-way folding here means that the strip is first folded in one direction and then in the other direction. [0004] The resulting fold line will cause the pages to be opened along that fold line, and when the bundle of pages is bound in the spine, the pages are placed with their snap fold lines against each other and flush so that the folded pages are nicely folded. ...
