The RG cantilevered press represents the culmination of over a decade of manufacturing flexo presses, wax coaters, differential coaters, gravure stations and a broad variety of custom processing equipment. The result is a very simple versatile print station that embraces the latest direct drive servo technology to provide a rapid production solution to the modern short run converte With a six color job change performed in just under 11 minutes and automatic register presetting a standard feature make-ready time is minimized and time in production is maximized. With simple touch screen operation, graphic web path diagrams, and a press that performs setup and print register automatically the operator is able to focus more on the finished product and less on being a make ready artist. Standard Features Direct servo driven sleeved Anilox roller.Direct servo driven sleeved Plate cylinder.Servo plate to anilox adjustment.Manual or Servo Impression to plate adjustment.Floating impression allows tissue, poly, and board to run back to back on any production day.Each station has differential anilox speed adjustments for ink or coating volume adjustment. When combined with our Coat Weight Monitoring system any station can provide a specific coat weight per bond ream.Automatic preregister is a standard feature that uses a pin on the plate cylinder to locate the plate sleeve and determine the new servo position for registered color to color print before the web starts to move.The Direct Register feature that is optional on our geared presses is now a standard feature and allows the operator to tell the press exactly how far to move any color.Remote Diagnostics for machine updates and maintenance assistance. Press frames are available in 1 to 3 colors per frame or tower. Each customer can mix or match frame combinations and web paths to fit individual production requirements.

Our dryer is a unique design configured to meet our press and retrofit requirements. The dry consists of ambient air, and IR elements with exhaust. Our compact design allows us to install or integrate with minimum space requirements. The dryers are speed sensitive, which means they increases. From the optional touch screen control you can adjust the IR start point, ramp rate, and maximum power. An electric control card ramps the infrared unit up and down based on the web speed. The control card provides adjustment range adequate to provide drying of medium to heavy formats without damaging or activating carbonless and direct thermal coatings with a critical temperature of 220 degrees F. There is an exhaust system which removes the ambient air moisture for the web The RG High Output Thermal Web Drying System provides superior performance for all water based flexographic printing and coatings applications.

An AC Vector drive powers the rewind stand for accurate roll speed. A twin roll dancer will control web tension in the rewind stand. The unwind is linked to the press via RG encoder and a central controller for high speed, accurate web tension control.A digital readout counter gives the operator the following recordable data:Totalizer (total daily output)Footage countAn Air Actuated Nip Roll is standard on the rewind stand to eliminate air trapped in the rewound roll and ensure tightly wound rolls.A spiral grooved spreading roll will be incorporated to aid in rewinding substrates. Built on two inch thick side frames with five structural cross members.Hydraulic Lift Out System

Each pump is computer controlled and linked to the press so they ramp up and down with the press speed supplying the required flow based on speed. Designed to reduce flashing in anilox cells by keeping the roller wet at all times using twin pumps to feed and return ink to the doctor blade cavity. The tower will handle two print stations All lines use quick release fittings allowing the operator to remove for cleaning or color change. The system takes five minutes to flush the cavity and clean anilox roller though multiple stations can be placed in to clean mode at the same time making for rapid job or color changing.

RG Engineering provides a variety of AC Vector driven slitting options that can be customized to meet your needs. The computer controlled lay-on nip and bowed rolls eliminate entrapped air producing perfect roll construction. Our shafted and turret rewinders are fitted with the RG high speed slitter head assembly. SLIT HEAD ASSEMBLY: A Heavy duty cantilever pivoting assembly and pressure roller assemblies ensure precise spacing and pressure to the rewound roll resulting in a perfect O.D. structure from core to finished roll. Both the shafted unwinds and rewinds can be equipped with our jumbo roll lift in and out automation. We also offer shaftless and turret winders. Feel the power of our AC Vector drive technology without using line shafts, clutches, or brakes. The vector motors electronically drive and control tension and are linked together to redistribute power from the unwind to the rewind. This connection reduces overall power consumption by as much as 20%.

Each model of Turret rewind features our long pressure arm with integrated taper tension and optional slitting. The pressure arm design provides a simple path for webbing and a compact splicing unit. The simple design and intelligent control produce a turret capable of very precise control of tension and roll quality.

RG engineering's flexographic presses can operate in the roll to roll configuration. Designed to operate in-line with any other converting equipment, the printers can provide no gap, no smear, no fault printing regardless of cycle times, when equipped with an optional festoon system. Full web or pattern coating can be performed without affecting the ability of a print station to operate as a standard flexographic unit. Servo driven printing stations maintain register without the need for continual adjustment. Multiple web path capability offers the advantage of simultaneously printing on each or both sides of the web in any possible combination. The machine is supplied with simple push button controls for presetting and register correction. Press frames are available in 1 to 3 colors per frame or tower. Each customer can mix or match frame combinations and web paths to fit individual production requirements.

The Auto Lap Unwind consists of two standard stacked RG unwinds with individual Vector drives and dancer tension control. An infeed drive and web reference roller control the festoon motion while a common splicing station cuts and nips the web from one roll to the other. A central controller monitors roll size, web speed, web caliper, festoon and dancer positions as well as operator settings for auto roll stop and web tension. This information is provided to the operator in a touch screen at the operator control panel. The unwind is described in three groups; the unwinds, the splicer, and the festoon. Auto Clamps: The shafts are held in place with an automatic shaft clamp that is pnuematicly operated and cams over for a fail safe lock. The air cylinders are built with a magnetic pick up for feedback to the PLC.Sidelay: The unwind motor is mounted on a sub frame assembley that rides on three linear bearings for 4 of total sidelay travel. The frame is moved with a screw through a hollow shaft gearbox. The sidelay feature is available with a manual handle, electric slo-syn motor, or servo motor positioning.Dancer: The unwind tension from the feed station to the master roll is controlled with air pressure on the dancer air cylinders. Two air cylinders are fed 0-90 psi air from an electro pneumatic valve. The dancer air pressure is selected in the touch screen and modified during splicing to reduce web breaks. Pass through festoon: The 15 roller festoon accumulates aproxamatly 120 of web in a stacked three pass design. When the festoon is in the lowest position limit the carriage idlers pass through the fixed idlers to allow the web to be passed through the gaps and sew its self up once the carriage is lifted.

Built on two inch thick side frames with five structural cross members and one steel, three inch in diameter, air locking shaft. The hydraulic lift-in system makes changing rolls a snap. Automatic pre-tensioning of the web after loading a new mill roll is a simple push-button operation. This feature removes undesirable slack from the web and positions the dancer to the preselected tension range prior to press start-up. A dancer roller assembly is used to sense web tension while an AC Vector motor is incorporated into the unwind stand to maintain proper web tension. Computer driven automatic end of roll system stops the unwound mill roll with minimal paper left on the core. A switch on the unwind stand allows for three preset core thickness settings.
