Komori Lithrone LSX640 With Coater to be Introduced at Drupa

The Lithrone SX40 has a new maximum running speed of 18,000 sph. The new higher speed fully automatic plate change

(F-APC) with non stop plate removal, helps increase the speed for job to job changeover, essential for busy print houses handling various run lengths. The Lithrone SX40 can change 6 plates in under two minutes, enabling, along with KHS-AI, a 35% reduction in job-to-job-changeover time. From the end of production on one job to an OK sheet on the next job it takes just 6 ¼ minutes. The automated coater plate change increases speed, precision and ease of use. All controls are integrated and automatic through the new PQC console’s touch screen. The new KHS-AI fast print start-up system has a self-learning function which progressively updates all press settings.

Changes to the feeder

The feeder on the new Lithrone SX40 has been developed for higher speed and to optimise the benefits of the new KHS-AI fast print start system.

The feeder board now requires no wheels and has an independent motor – not driven by the press, so sheet arrival timing can be adjusted electronically – which enables greater control now that the press accelerates towards maximum speed faster.

The front lay area has been modified in order to improve handling of lightweight materials – especially at maximum press speed.

Within the feeder head mechanism, we have modified the cam follower drive to maintain constant contact at the highest speed. This ensures a highly accurate sheet separation and transfer with minimum maintenance.

On top of the feeder pile, we have introduced an air containment system to allow precise sheet transport with the minimum of air, even when feeding at the higher maximum speed.

We have also increased the number of front lays and modified the air control in the sheet infeed area to ensure precise register at this higher speed.
