The Horizon BQ 470 is a used perfect binder — also referred to as a thermobinding machine — designed for automated book production. Perfect binders are used in commercial and trade printing to bind books, catalogues, brochures, and journals by applying adhesive to a milled spine and attaching a wraparound cover. Horizon is a well-established Japanese manufacturer of post-press finishing equipment, producing bookbinding, folding, cutting, and collating machinery for the printing and publishing industries worldwide.
This machine is a fully automated four-clamp perfect binder from 2009, fitted with a PUR gluing unit supplied by SM Klebetechnik (model GX2311), and carries serial number . It is located in Germany. PUR (polyurethane reactive) adhesive systems offer superior bond strength compared to conventional hot-melt glue, making them particularly suited to challenging substrates, coated stocks, and lay-flat binding applications.
The unit handles a broad range of book formats, accommodating book blocks from a minimum of 145 × 105 mm up to a maximum of 320 × 320 mm, with cover sheets up to 320 × 660 mm and a minimum cover size of 135 × 225 mm. Book thickness can range from 0.3 mm to 65 mm, covering everything from thin pamphlets to substantial volumes. Paper weight ranges are similarly wide: 60–135 g/m² for book block stock and 81.4–302.4 g/m² for cover material. The cover pile height reaches a maximum of 150 mm, and milling depth is adjustable from 0 to 4 mm to suit different spine preparation requirements.
Production speed is rated at 1,350 cycles per hour. The machine features four-position creasing with both positive and negative creasing options, plus two additional creasing stations, enabling precise and clean cover folding across a variety of cover weights. A palmar system handles automatic book adjustment, and book thickness is entered via a Horizon SI-470A input caliper. Cover feeding is by suction, with a supersonic double-feed detection sensor to prevent misfeed errors during production. Gluing is handled by a dedicated glue tank unit, and lateral side glue capability is included for additional adhesive application at the spine edges.
The delivery system is a Horizon SI-470A conveyor. A smoke extractor is fitted, which is standard practice when working with hot-melt or PUR adhesive systems. The operator interface is a colour touchscreen panel. Electrical requirements are 400 V three-phase (rotary current) at 16 A, with 6.5 kW specified for the adhesive binder unit and a separate 400 V / 16 A / 6.0 kW supply for the melting unit. Standard accessories are included with the machine.
