Flexonyomógépek, tekercsvágók, laminálók gyártása | Flexo printing unit

Flexo printing unit

Flexonyomógépek, tekercsvágók, laminálók gyártása | 8 colors - Central impression cylinder

8 colors

8-color robust cast iron framework with 8 printing decks The massive cast iron framework ensures that vibration is minimized and as a closed unit it guarantees stability and protection for the 8 inbuilt flexo printing decks. In addition robust spacers join the two sides.

Central impression cylinder

The central impression cylinder is the prerequisite for top quality printing. Double-walled, tempered, 1800 mm diamteter stainless cylinder with 0,005 mm accuracy ensures that the material will not stretch (deform) during the printing process. The cylinder turns steadily thanks to the self-setting bearing with cylindrical roller. The bearing doesn`t require maintenance. The tempering unit is part of the basic configuration.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Gearless servo-CNC Motorized printing deck actuation-Vibration damping

Gearless servo

Gearless and servo driven printing form and anilox sleeves. The inbuilt air cylinders of the form and anilox sleeves are servo driven, thus any print length can be set without the 5 or 10 mm limit. The girth of the plate mounted onto the form sleeve is saved in the system and the servo inverters automatically set into the needed position due to a high-accuracy feedback. There is no more resonancy caused by older machines' cog wheels as a result faults on the print due to vibration reduce.

CNC Motorized printing deck actuation

PLC controlled, servo driven actuation of the printing decks and of the length register. Each printing deck is actuated by 4 servo engines moving precision screws and carriages. Accuracy of the positioning is to 0,001 mm, with zero backlash. Machine operators can set the compressive force and the servo driven cross and the 360° length registers on two portable and two color touch screen terminals. These values along with many other important parameters are saved with the recipe program, which ensures that work data for recurring jobs is stored.

Vibration damping

Vibration damping system in each printing deck.
Plate engagement and disengagement during print cycle causes vibration which needs to be absorbed in order to neutralize resonance streaks, so all printing decks are equipped with an anti-vibration system.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Sleeve system

Sleeve system

Side shift mechanism anilox and form sleeves. Specifically required sleeves are placed on the fixed built-in air-cylinders in the Flexographic press and their exchange can be done from the operator’s side of the printing deck after the quick release of the bearing block assembly. Therefore, changeover time is greatly reduced. The total print length range is most economically attainable by two adapter sleeves. The exchange of the form and anilox sleeve is aided by two specifically designed carts which are standard equipment. They reduce the likelihood of damage and ensure safe storage of the form and anilox sleeves. Plastic protective cover is an optional accessory for the anilox sleeve, which should be used during sleeve exchange in order to protect the anilox sleeve mantle from damages. For special request we can produce compact, easy-to-use form sleeve rack or storage when all form sleeves of the machines can be store safe and further form sleeve transport carriage which can solve safe and easy transport between the storage, the plate mounter and printing press.


Flexonyomógépek, tekercsvágók, laminálók gyártása | Doctor blade chamber and ink application

Doctor blade chamber and paint application

The blade chamber is one of the most important units of the paint application technology. It is precision-machined cast aluminum with Teflon surface. We fixed blades on the top and bottom of the cast and standard size felt end-seals on the sides, which can be replaced in the printing deck without removing the doctor chamber. The equipped Doctor Chamber is simultaneously pressed against the anilox sleeve by adjustable pneumatic pressure, resulting in a closed chamber. The inlet and outlet hoses are fastened to the backside of the pump and the ink box by quick connectors. Ink is circulated via burst proof pump to the chamber from a stainless steel toner box, situated on two support carts, which are included in the base price. The blade pressed against the anilox sleeve ensures that excess ink is removed, thus the quantity of the applied ink can be controlled by the size of the cells on the anilox cylinders. In order to increase or decrease the quantity of the ink, the anilox sleeve needs to be changed to another size. Ink recirculated through the stainless steel ink box is filtered for metal particles by a magnet. Easy cleaning, low weight, fast and simple maintenance was the primary objective during the design phase. Assembly and storage of the Doctor Blade Chamber, and Doctor Blade cutting, is aided by a specifically designed cart which is standard equipment. Viscosity control, automatic washing system with pneumatic pump, stainless steel anilox sleeve, and the Doctor Blade Chamber washer carriage are available options.


Flexonyomógépek, tekercsvágók, laminálók gyártása | Automatic Print Setting

Automatic Print Setting

Automatic print setting within 20 m. The automatic print setting system is a software solution that sets compressive force and length registers on all 8 printing decks simultaneously within 20 meters. As a result, we will receive a print which the machine operator needs to only fine-tune to achieve a perfect print. Human factor will always play a vital role in precision settings on any system, therefore, the machine operator’s role will always remain vital. The amount of rejective print and changeover time is greatly reduced by this system. The system is included in the basic accessories.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Print 4.0
Flexonyomógépek, tekercsvágók, laminálók gyártása | Speed


The mechanical speed of the press is equal to its highest printing speed of 400 m/min, even during 8-color quality printing. In some cases, however, substrate specifications require lower speeds. According to customer feedback, we can say that on average 150-200 000 meters of printing can be accomplished daily, with 5-10 changeovers, in a 24 hour shift.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Width


The determinative parameter of a Flexo printing press is the width of its print. According to customer feedback, 80% of printing requirements are less than 1000 mm in width, so the majority of the printers are ordered with a 1000 mm maximum print width and an 1100 mm substrate width. Being a custom Flexo manufacturer, we offer a range of 500–1200 mm width, to meet customer demands.

Print repeat

The minimum print length is an important factor due to the declining number of copies, because during multiple production printing, the cost of printing plates increase, which the customer does not always accept. As a result, our print length can be set from 300-900 mm, enabling smaller print plates which help reduce their cost.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Web Video Inspection

Web Video Inspection

With the help of a web monitoring system we can check the print under running. A digital camera shoots still images of the print and displays the pictures on a fix and a rotatable 19” LCD flat screen. The optics and the camera is moved by inbuilt motors even with automatic scanning. The print control system is available with two cameras (top and bottom), so during the “mirror-normal” print operation only the bottom or the top camera has to be selected, additional adjustments are not required. The substrate need not be rethreaded, so changeover time will be shorter and simpler. Print examination is facilitated by a print inspection table, standard equipment, with D50 self-lighting and is also ideal for storing the necessary tools and equipment for the operators. The print control table can be supplemented with a digital microscope to view the magnified print on a 49 "monitor.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Drying


Fast paint drying is ensured by a hot air drying system in the drying bridge and between the printing decks. Air from the blower ventilators passes through heating elements as it dries the ink and then gets drawn out by exhaust fans. Optional hot water preheater can be ordered to reduce power consumption.
The operation and temperature of the drier, with multiple automatic settings, is individually controlled via color touch screen terminal both for the bridge and printing deck. Air quantity can be controlled between the printing decks with manual valves also. Heat exchanger for hot exhaust air recovery is optionally available or drying air concentration measuring LEL system which task to circulate the warm drying air in closed circuit and automatically mix fresh air to this depending on the concentration thus saving significant heating energy.

Flexonyomógépek, tekercsvágók, laminálók gyártása | Winding


The purpose of the winding system is unwinding and rewinding of the substrate. Basic configuration includes one manually changeable unwinder roller and one manually changeable rewinder roller for an 800 mm maximum reel diameter with pneumatic expanding shaft. The largest reel diameter can be expanded to 1000 mm reel diameter and shaftless conical reel mounting is available on request. A non-stop-changer unwinder and rewinder unit with an 800 mm maximum reel diameter is optional. Each winding unit is controlled by separate motors and top-quality servo inverters with built-in pulling force dynamometers, which maintain a constant positive pulling force of 5 Newton, with minimal energy, regardless of actual track speed and reel diameter. The desired positive pulling force can be set on a color touch screen terminal. The rollers are suitable for bi-directional. Edge control system equipped with motorized adjustable ultrasonic sensors is fitted in front of the winding roller and in back of the unwinding roller to ensure uniform lateral positioning of the substrate. Pneumatic rubber nip rollers on the take-up reel, adjustable on either side, help expel air from between the layers of the film on the reel. As the substrate exits the drying unit, it travels through a cooling cylinder to assure proper temperature for rewinding. In case of OKTOFEX PREMIUM threading the raw material is ensured via a motor-driven lacing chain at the drying bridge, which drives the dryer rollers during printing.
