AR70A Flying Paster/Splicer

AR70AFlying Paster/SplicerProven Performance & High Productivity for NewspaperSemi-Commercial & Commercial PrintingThe AR70A continues the success story of the AMAL AR60 and AR70 proven in hundreds of installations.Consequently, the advantages of these models have been combined into the new model AR70A.Manufactured with the latest production methods, the AR70A delivers highest perfomance at an attractiveprice.The bottom line is process knowledge

Splicing : The new roll runs at synchronousspeed. When the pre-set splicing diameteris reached, a splice roller presses the webstogether. The cutting knife severs the old webLoading of rolls of different web width duringrun is possibleOperator displayPLC ControlThe pasting cycle and running operationsare automatically managed by a PLC. Likeall MEGTEC Webline products, the pastercan be integrated with the press controlsystem. The integration of the paster intothe web-up system is available for manypress types.Operator InterfaceThe operator panel features a touchscreen control for paster setting with adisplay screen for status, fault history,service diagnosis and help screens. Keyfunctional hard buttons are available inthe machine side frame.Stable TensionStable web tension with minimum variationis assured from the pneumaticdancer roller assembly with potentiometermeasurement. Tension is managed by acontroller which regulates the core brakesto keep the dancer constantly in balance.Core braking provides fast and stabletension control with minimum variation toimprove productivity by reducing paperwaste. The pneumatic brakes on each armensure optimum operation and requirelow maintenance. Tension performance isfurther improved by the short web leadsof the AR70A.Easy Roll LoadingThe loading of the pasters by lightweightshafts is very easy. When changing toanother production run, a roll of adifferent width can be loaded whilerunning the press. Roll loading is directlyfrom the floor into the arms, no hoist isrequired. The low minimum roll diameterfor splicing of 275 inches (700 mm) allowssignificant flexibility for running part rollswithout re-winding or special handling.Normal and symmetric configurations areavailable for dual web center loading.Illustration HereThe optional ROLLOAD® handlingsystem enables i.e. roll preparation at acentral unwrapping station. Roll data canbe registered and processed. The benefitsof operation include reduced paper waste,higher efficiency and enhanced safety.Reel ShaftsFor over 40 years MEGTEC has usedpneumatic reel shafts for variousapplications. Continuous developmentand experience result in the design andthe quality. The reel shafts of the AR70Ahave been optimized specially for lowweight and long life. An aluminium type37.4 lbs (17 kg) and optional combinedcarbon-fiber/aluminium type 28.6 lbs (13kg) are available.Optional InfeedTension control begins at the paster.MEGTEC pasters and infeeds canbe controlled in tandem for optimumperformance. This allows the paster tooperate at a low tension to limit tensionvariations to the infeed (which alsoreduces brake maintenance). Infeedsprovide more stable web tensions thantraditional designs. Their extremely stabletension is made possible by the use ofhigh dynamic servo regulation with lowinertia mechanical elements, a load celland nipping roller.Shaftless infeeds provide fast andaccurate tension control. Two versions areavailable:• Integrated version can reduce overallpress length by up to 6.5 ft (2m)• Independent units with optional webguides
