Abstract: This system is provided with: a conveying device 1 that conveys paper P along a conveying path F; a sheet paper supply device 2, paper-folding device, or cutter connected to an upstream end of the conveying path; a gathering device 3 disposed midway through the conveying path; a saddle stitch device 7 connected to a downstream end of the conveying path; and a management unit 13 that collectively controls the conveying device, the sheet paper supply device, the paper-folding device, the cutter, the gathering device, and the saddle stitch device. The gathering device can switch operation between a non-operating mode, a first operating mode for operating as a primary gathering device, and a second operating mode for operating as a paper insertion device.

Abstract: The gluing unit is provided with: a glue tank (2); a glue applicator roller (3) that applies the glue on the back (r) of a text block (P); a motor (4) that rotates the glue applicator roller; a wiper (6) that adjusts the amount of glue adhering to the glue applicator roller; a wiper drive mechanism that brings the wiper closer to or away from the glue applicator roller; and a control unit (10) that controls the wiper drive mechanism.

Abstract: The glue application unit comprises side glue application members which have a pair of scrapers (7, 7) and can engage with the back margins (s) of the book block (P). The scrapers consist of elastic rod-like bodies (7a) and scraping portions (7b) provided at leading ends of the bodies. The scrapers obliquely extending in a direction of movement of the book block from the outside of the path of the downwardly protruding portion of the book block into the path in such a way that the scrapers contact each other in an inverted V shaped configuration. The scraping portions engage with the back margins of the book block by the elastic biasing of the bodies while the downwardly protruding portion of the book block passes between the scrapers.

Abstract: Movable guides are moved in vertical direction by guide drive units between a retreating position and a protruding position. A setting section is provided for setting a contact start point on a sheet and a contact end point on the sheet. The movable guides are moved between the retreating position and the protruding position so as to keep contact with an area of the sheet from the contact start point to the contact end point while a product separated from the sheet is conveyed from a first conveying unit to a second conveying unit.

Abstract: A machine for attachment of a cover to a book block comprises a press plate elevating mechanism for elevating a press plate 8, a nip plate drive mechanism for sliding nip plates 9 and 10, and a controller 30 controlling the press plate elevating mechanism and the nip plate drive mechanism. The press plate 8 elevates from the lower standby position to an upper press position. The press plate 8 presses the cover 12 to the book block 4 at the upper press position. The cover 12 is attached to the book block 4 by pressing the cover 12 to the lower end surface of the book block 4. The press plate 8 is elevated from the intermediate position to the upper press position, staying at the intermediate position during a waiting time for adjustment. The press plate 8 elevates from the intermediate position to the upper press position.

Abstract: The movable guides 21 are moved in vertical direction by the guide drive units 22 between a retreating position and a protruding position. The setting section 29 is provided for setting a contact start point on the sheet and a contact end point on the sheet S. The movable guides 21 are moved between the retreating position and the protruding position so as to keep contacting with an area of the sheet S from the contact start point to the contact end point while the sheet S is conveyed from the first conveying unit 15 to the second conveying unit 16.

Abstract: The gluing unit is provided with a sideways glue-applying member which can engage with throat regions (s) on both sides of a spine (r) of a book body (P), and the lateral glue-applying member is provided with a pair of scrapers (7, 7). Each scraper of the pair of scrapers is configured from an elastic rod-shaped main body (7a) and a scraping part (7b). The rear ends of the main bodies (7a) are fixed to a frame (1) on both sides outside the path. The scraping parts (7b) are positioned further downstream than the top surface of a glue application roller (3) in the path. While a portion of the book body that projects downward passes between the pair of scrapers, the scraping parts engage with the throat region on both sides of the spine of the book body.
