Specially designed Cart facilitates ease for insertion and extraction from the printing station. Thanks to a special mechanism: Cart slides on linear guide rail which ensures perfect in & out operation; only one operator can easily carry out the operation.

To carry out loading I unloading of gravure cylinder there is a lifting system onboard on the cart, which consist of hydraulic piston, levers etc.

  • Possibility to remove only the inking system, leaving the printing cylinder in the printing station
  • Possibility to remove only the printing cylinder, leaving the inking system in the printing station
  • Possibility to remove the printing cylinder together with the inking system at the same time

High efficient ventilation module ensuring optimum drying at minimum energy consumption. The system comprising servo controlled dampers to set recycling of supplied air to the drying hood and setting of the exhaust air

Each ventilation module composed of :

  • Thermal oil heat exchanger with necessary controls/feedback devices to maintain set temperature
  • Central exhaust system common for all printing units
  • Separate fan with necessary duct for floor sweep which ensures to reduce solvent ontaminated odour within the lower area of the printing stations

Doctor blade group sliding on low friction ball bushings to eliminate the stick-slip problem. Very sturdy doctor blade group, independently adjustable in height, parallelism and angle. In addition, the group can be tilted backward to allow the replacement of the doctor blade without use of tool.

Designed to ensure a straight profile of the blade resulting in lesser blade pressure, better print quality and longer cylinder life.

Doctor blade supporting assembly with precision adjustment for height and parallelism to the printing cylinder, thus allowing to work in different doctor blade angles; reference position scales, to guarantee repeatability for future productions.

Turret type Unwinderwith flying splice.

The system mainly composed of push button initiated motorized rotating disc, pneumatically loaded automatic splicing arm, rubber covered asting roller and cutting blade assembly etc.

Pneumatically expanded shafts and safety chucks to hold the reels.

Unwind Web Handling Control using latest generation AC servo technology. The system mainly composed of AC servo motor and drive, pneumatically loaded low friction dancing roller assembly and load cell for tension feed-back and actual tension display.

Electro-electric Edge Guiding System

The system provides precise tension control of the web before entering to the first printing station and isolates the printing unit from tension disturbance of the unwinding zone.

Dancing roller on pivoting lever mounting loaded by a counterweight (Unique mechanism for tension feedback) having motorized movement by means of slo-syn motor.

The dancing roller position controls the speed of the in-feed motor.

The sleeve system , consists of an air mandrel with a rubber covered fibreglass sleeve.
Raising- lowering on precision sliding guides with low friction ball bushing, which ensure smooth and precise displacement.

Automatic detach of the impression sleeve at machine stop by using special pneumatic cylinder having intermediate stoppage facility.

Innovative high efficient drying system: better heat and mass transfer are achieved by switching from the standard nozzle to arrays of circular impinging jets "3D" holes on the printed side and "2D" holes on the backside, blowing on both sides of the web.

Holes shaped and distributed on stainless steel plate to guarantee the maximum energy transfer efficiency and minimize the number of idle rollers in order to avoid shaking or deforming of the web itself.

The system allows full process control for the drying operation to reduce energy consumption and avoids solvent retention in the printed substrates. Pneumatically operated drying hood opening/closing to allow easy access for web threading and cleaning.

The system provide precise tension control of the web before entering to the rewinder and isolates the rewinder from tension disturbance of the printing unit. The system mainly composed of AC servo motor and drive, pneumatically loaded low friction dancing roller assembly and load cell for tension feed-back and actual tension display. The dancing roller position control the speed of the out-feed motor.

The C.P.S. is a press/operator interface system consisting of: One industrial type personal computer, installed in the main control console that provides a graphic representation of the various applied programs.

Functions of CPS Systems are:
Preset: Data base management and press pre-setting of repeated jobs, the controlled points are: angular position of printing cylinders, web tension controls and electronic temperature controllers.
Diagnostic: Display of the detected faults and press stop causes, with the electrical cabinets reference indications. Each fault and press stop duration is recorded.
Synoptic: Press layout with operating conditions display.
Monitoring: Digital and analogue press speed display, Production footage (total and partial), Historic trends of: air temperatures & press speed.
