KBA Patras is robust yet flexible, requires a minimum of maintenance and represents outstanding value for money. Optimising your paper logistics with Patras delivers substantial savings in both costs and waste.
The choice of module-based configurations ranges from manual to fully automated, supporting total customisation to suit both your production technology and the space available.
The KBA Pastomat high-performance reelstand with central drive can be easily integrated into an automated paper logistics system.
A new reel is automatically spliced onto the expiring web at full production speed. The Pastomat beltless technology makes for easy splice preparation.
The divided arms on the Pastomat are infinitely adjustable by remote control. Their ability to handle reels of different widths affords a high level of flexibility in handling a wide range of different products.
Four forme rollers, one of them reciprocating, transfer the ink uniformly to the plate and reliably prevent ghosting. The speed of the motor-driven duct roller can be regulated both from the console and from thedesk. The inking and dampening duct rollers have freely storable acceleration curves.
The high-capacity ink ducts with rigid crossheads and a precisely defined throw on position can be connected to a central ink supply. The ink knives are segmented into zones and can be preset and remotely adjusted from thedesk. A digital link to obtain presetting values from pre-press is standard.
Two AC drives per printing unit allow the plates in the upper and lower printing units to be changed simultaneously. But that is not all: the drive concept also enables the circumferential register to be set fast and precisely with a minimum of mechanical input. The electric motors controlling the setting mechanisms offer far greater precision than mechanical systems.
Because there are two motors for each printing unit, less braking and accelerating force is generated than with the singlemotor systems more common today. This technical innovation helps reduce mechanical abrasion on components, which, in turn, means less maintenance. The printing units are water-cooled to promote operational consistency, even during long production runs.
The circumference of the plate and blanket cylinders has been reduced by minimising the lock-up slot. This has the advantage of not only reducing paper consumption but also of enhancing print quality by eliminating vibration at high press speeds.
The plate cylinder and solid steel blanket cylinder are both nickel-plated, dynamically balanced and run in maintenance-free triple-ring bearings with zero play. Broad bearer rings made of special steel ensure a smooth run and increase the service life of the press. The blanket is tensioned evenly via two spindles. Adjustment of the sidelay, circumferential and diagonal register from the console cuts makeready times and waste.
Rollers set with optimum precision ensure that ink is transferred uniformly across the entire width.dramatically reduces roller abrasion, and thus the frequency with which rubber coatings must be replaced, thereby delivering further cost savings. It obviates uneven wear and tear arising from the incorrect positioning of the rollers relative to each other.
Correct roller settings reduce maintenance costs and energy consumption while promoting optimum production conditions.
- Much lower maintenance costs
- Less frequent renewal of rubber coating
- Better energy efficiency
- Greater process stability
- Optimum printing conditions
The patented microporous turner bars are one of the many proven features that are unique to KBA. They dramatically reduce the consumption of compressed air and thus conserve energy. They also do not need to be set for different ribbon widths. Contamination- and smear-free, the turner bars operate reliably with a minimal air cushion to promote a smooth ribbon run.
In combination with optional features, such as skip slitters, ribbon and section stitchers, gluing and softening devices and a splitting unit at the folder delivery, these presses can handle an enormous range of products addressing widely diverse market demands.
The electrically controlled dedicated drives for the draw rollers maintain a uniform web tension. They are preset and adjusted from the console, dramatically slashing both setting and makeready times. Cooling rollers cool the web to ambient temperature prior to infeed into the superstructure. The four- or fiveroller KBA chill-roller stands have a large wrapping angle for maximum efficiency. This reduces the consumption of cooling water and energy. Hot-air dryers with integrated chill-roller stand are available as an optional extra.
Fast P5 pin folder
The modular design of this highperformance press means that you can specify the configuration best suited to your operations and your market.
The basic version offers a choice of production runs with first crossfold and quarterfold in collect and non-collect mode. A double quarterfold and overhead copy guidance into the delivery of the lower quarterfold are standard features, as are length and cross perforation. The next expansion option is a separate delivery for crossfold production. The third expansion phase is the installation of a second parallel cross fold. A section stitcher is also available as an optional extra.
Whatever the level of sophistication you choose, you will find that the convenience and speed of automated press presetting and conversion from the console will support a wide variety of products by helping to minimise makeready and changeover times. With the P5 you can keep abreast of market trends by offering your clients new and attractive products.
Winning features are the remotely adjustable first and second crossfold, and a quarterfold unit comprising a single module. This supports a wide choice of folds while dramatically shortening changeover times. The length and depth, as well as the depth and circumference, of length and cross perforation can be adjusted on the fly in order to adapt perforation and folding accuracy to stock type and production conditions with a minimum of waste. Belt paths in the P5 folder are shorter and wider to ensure a smooth copy transport.
A pneumatic belt-tightening system effectively counters elongation and maintains a constant tension. This reduces abrasion and thus maintenance input. Belt tension can also be adjusted on the fly.
The P5 and V5 folders in our newgeneration double-circumference presses have automated copy control in the quarterfold, a feature that has already proven its efficacy in the C16.
Copies are slowed effectively and with a minimum of abrasion, while simultaneously being aligned in the direction of fold during deceleration. Automatic copy control is self-adjusting and exceptionally reliable, regardless of production speed and copy thickness. As a result folding is consistently accurate, even during changes in press speed.
The P5 folder combines production flexibility, rapid conversion, accurate folding and low maintenance with extreme reliability and easy handling.
Web offset printers whose flexibility is often limited by the fixed format of their presses will welcome our V5 gripper folder's ability to process both short- and long-grain products.
This option has already motivated many users to opt for one of our double circumference presses. The know-how invested in the V5 is drawn from KBA's longstanding experience with gravure printing folders.
The flexibility offered by the V5 gripper folder means that, in the case of the C72 for example, it can deliver 72 A4 pages in long-grain production, while in short-grain production it can deliver 96 copies in near-A4 format. The V5 is thus an effective asset in an increasingly
competitive commercial printing market.
In order to make the most of this versatility you need a superstructure capable of handling a large number of ribbons. Cut-off cylinders at the infeed to the V5 folder allow different cut-off lengths, e.g. 620 or 413.3 mm (24.4 or 16.27in). It goes without saying that the V5 incorporates all the familiar technical features of the P5 folder including dedicated plate-cylinder drives.
By supporting a far broader range of products the V5 maximises web press utilisation without the need for aggressive price concessions, thus enhancing press economy. By offering an extensive range of products you can stand out from the competition and react more flexibly to shifts in market demands.
The V5 also offers many other benefits, including more room for manoeuvre in a fiercely competitive marketplace. In some cases, it can even save you the expense of investing in a second press for short-grain products. Exploiting the V5 folder's full potential can bring substantial bottomline benefits.
This is a big advantage – particularly when printing low-pagination copies – and substantially reduces costs while enhancing output. In some cases, the cutter offers a useful alternative to our commercial folders. It optimises production of 4-, 8-, 12- and 16-page copies.
- Cuts to 1/3 or 1/4 circumference
- Two infeed formers, movable sideways and with the web run
- Variable infeed width
- Variable length trimming opposite the former nose
- Splitting units in the spider wheels
The console for the new C series is a perfect interplay of functionality and aesthetics. All essential production commands, including automatic folder conversion, are initiated at the console. Easy-read data screens with plain-language displays on the touch screen facilitate operation.
KBA Support Online
A 24/7 service hotline ensures prompt and effective customer support. The computer in the service department can communicate with the C series via a network or the internet. Any malfunctions that may arise are generally detected within a very short space of time, so remedial action can be initiated without delay.
Thedesk is the operator's primary workstation and permits optimum handling of the ink settings. A presetting system for the ink keys is part of the standard package. Broad LED strips provide an immediate indication of the ink profiles set and facilitate fast corrections when necessary.
A CIPLink interface for transferring prepress data is included in KBA. CIP3 files are accessed via a local network. Optional CIP4 capability is also available.
Our KBAautomatic press presetting system boosts productivity and helps to minimise waste. Winning features include rapid web tensioning, automatic presetting of the cutting unit, turner bars, register rollers and former when setting up a new job, run-out washing in accordance with production demands and defined pre-inking. The ability to preset all the components in the superstructure and the folder according to pre-press data is available as a further option. Optimised press start-up, makeready and run-down are actuated at the touch of a single button.
All KBA commercial web offset presses are fitted with the basic version ofas standard. This ensures transfer of essential preset data to the press. It includes an optional CIPLink module with reel and ink-data capture. The workflow is networked using in-house hardware (server), and ink-key, colour and dampening data can be transferred to the press for presetting.
As a further option the console can be configured withProfessional, an open-architecture production management system that supports production monitoring, the digital flow of job and presetting data, and the systematic evaluation of production data. It connects the press to upstream production planning and scheduling systems and commercial IT. This wellproven system translates production and administrative data into meaningful statistics and makes for greater transparency by capturing press and operational data. Professional is a crucial link in the communication chain between the KBA press and the printshop's management information system. New KBA presses can be embedded at any time in an existing Professional scenario with KBA sheetfed, newspaper and commercial web presses, creating both synergy gains and a uniform platform for all the presses in the printing plant. The database supports direct access or access via JDF.
Thecomponent PressWatch provides management with an overview of all the jobs currently being run. Counter states, printing speeds, job data and progress, press status messages and a whole array of other relevant information can be displayed in real time.
SpeedWatch also creates a time/speed diagram in real time, with which all events and messages for a selected press can be depicted. Authorised persons can access this information via the internet or the company intranet.
Interconnection ofProfessional via the universal interface JDFLink offers the following advantages:
- Uninterrupted automated workflow (job data can be passed directly from dedicated software to the press console, eliminating job dockets)
- Access to Professional from all connected workstations
- Presetting and repeat data help shorten makeready times
- More effective production per shift
- Less waste
- Single data input enhances efficiency and reduces the risk of errors
- Improved cost accounting on the basis of exact press and production data (no daily worksheets to be completed by hand)
- Clearer overview through ability to retrieve all job, presetting and press data
- Comprehensive and transparent information for management
