The Three Knife Trimmer D09 is designed for industrial manufacturing of single products up to medium runs in the hardcover and softcover sector. Its excellent cutting quality, universal format range and very high degree of automation sets new standards. A unique option is the motorised format change that is performed in seconds at the press of a button or by barcode control. Patented, adjustable pressing tools (table and pressing block are no longer required!), cover the entire range of formats.
The books are fed spine first into the machine and are gently guided into the head and tail cutting station by belts. The angled swing cut against cutting bars and against the book spine guarantees the very high cutting quality of the head and tail cut. Then the front cut is performed, which is also precisely positioned and aligned with full surface pressing. The books are delivered spine first. The cutting waste falls down, assisted by air blowing nozzles. An external removal system (belt, extraction etc.) can be easily connected. Very large cutting widths such as those encountered in digital printing are also possible.
■ straight infeed ■ automatic set-up with format input via touchscreen ■ central lubrication with hand pump ■ adjustment by hand ■ SPS controlled ■ automatic material control ■ adjustable speed ■ delivery with roller belt ■ set of HSS knives ■ Offline or Inline mode possible ■ automatic thickness control at Offline mode
Special equipment (option):
■ left or right hand infeed with counter stacker ■ single book option with thickness measurement and barcode reader on additional feeding belt ■ front cutting unit for cutting of books with folded-in flaps ■ waste removing for connection to a vacuum extraction ■ waste conveyor for moving the cut-off out of the machine ■ waste carriage ■ hard metal knives ■ modem for diagnostic
The DGR Perfect Binder KM 41 is designed for fully automatic manufacture of adhesive bound and thread sewn blocks (hardcover) and brochures (softcover). High-quality book blocks (for hardcovers) can be produced using the integrated, optional end sheet station and lining station. It can be used for processing gathered loose sheets and/or folded sheets or thread-sewn blocks. With the full equipment, there are 3 possible product variants:
1. Brochure with cover, 2. block with glued and lined book spine, or 3. a combination of the two as a brochure with lay-flat binding (e.g. Swiss/Euro brochure) produced in one pass.
The integratable end sheet station is a particularly rewarding investment as it has a return on investment of only a few months for short run hardcover books in the area of digital printing. Thanks to the motorised format change (optional), the different production types and formats can be very quickly changed. For the single copy option, it is possible to change with zero make-ready time.
The collated or thread-sewn book blocks are conveyed to the infeed of the machine where they are read in and measured in thickness. Each block is cycled in and guided in a vertical and linear position into the vibrator station. The end sheet station (optional) transports the end sheets into the bottom of the channel, from where they are guided parallel to the block, bypassing the spine processing. They are then glued to the pre-glued block. The block and end sheets are then lined together (optional) and/or provided with a scored cover. In the pressing station, the spine and sides of the bound product are cleanly pressed, giving it the desired square edged spine shape before gentle product delivery.
■ Automatic format change with servo motors (optional) ■ Integratable end sheet station ■ Integratable lining station ■ Processing of book blocks, brochures or Swiss/Euro brochures ■ Glue types: PVA, hotmelt or PUR (also in combination) ■ High product quality thanks to sturdy and compact design ■ Simple operation by a single operator ■ Offline or inline operation possible ■ Special single copy option for individual products ■ No mechanical exchange parts

DGR Book Line RHLE 30
The DGR Book Line RHLE 30 is a new, automatic book flow line, complete with downstream joint forming and pressing station for economic industrial manufacture of conventional hard cover books. This book line offers state-of-the-art technology, fast change-over without the need to change format parts, and now also allows short, very short print runs and even individual copies of qualitatively superior books to be produced with consistently high quality and extremely attractive unit costs.
The entire DGR Graphic Book Line RHLE 30 line is designed for books with rounded or square spines, and includes a rounding station, backing station and headbanding station, as well as the casing-in station itself. On request, the DGR Book Line RHLE 30 can also be supplied as a pure casing-in line in a shortened version for books with square spines, see Casing-in machine E30. The downstream joint forming and pressing station with delivery section is identical in both versions and completes the perfect book production, see Building-in machine FE33.
■ Very short make-ready times (no need to change format parts!) ■ Automatic motorised format change (optional) ■ Simple operation by a single operator ■ Superior industrial book quality ■ Small footprint ■ Offline or inline operation possible ■ Special single copy option for individual books
DGR was founded in 1997 by mechanical engineers Gerd Depping and Horst Rathert (Dipl. Eng.). Horst Rathert managed the new development of the company for 12 years as Co-Managing Director. Gerd Depping has been sole Managing Director since 2009. The company's first headquarters were in Stemwede. Due to space constraints, the company relocated to Espelkamp in 2001. DGR initially started with the construction of small format casing-in machines, specifically intended for the manufacture of diaries. However, these machines were also used in special solutions, for example, for producing German passports and for manufacturing bibles, and were sold throughout the world. For the first few years, the young company produced special solutions and customised machines in addition to the production of the small format casing-in machines. DGR developed a special solution for the Bundesdruckerei (German Federal Printing Office) in Berlin for assembling German passports. Today these are exclusively manufactured on the DGR machine. At DGR we soon recognised that the manufacture of diaries (soon to be almost completely relocated to the Far East) was a declining market, and started to consider new fields of activity. Thus we decided to focus on the development of machines for the growing market of small print runs in book production. In cooperation with a customer in South Germany we initially developed a hardcover flow line. This was followed by a three-knife trimmer and finally a perfect binder. Thus our product range included all the main machines for book production except a casemaker. Our objective was to achieve a very short make-ready time and avoid the use of make-ready copies by dispensing with exchange parts and using reliable state-of-the-art technology. This approach has recently enabled DGR to market machines for economical single book production and very short runs in conjunction with digital printing. In this way, we have been able to develop substantial expertise in addition to our extensive experience in the paper finishing industry. Currently, only the DGR machines allow economical production of hardcover and softcover products as single copies or in very small series. Our new developments are protected by comprehensive patent applications and are currently unrivalled in certain market niches.
