Responding to converter demand for more streamlined
finishing workflows and increased productivity, Rotoflex has redesigned its
well-known DSI die cutting platform to be a smaller footprint machine which is
faster and more responsive to today’s changing production requirements.
A powerful contributor to this redesign is the incorporation
of servo drives into the platform. Smaller than the legacy AC vector motors,
this reengineering has decreased the size of the power cabinet significantly,
thereby reducing the footprint, a real benefit in facilities where floor space
is at a premium. The independently driven servo drives manage the unwind, die
cut, matrix and rewinds, and are controlled by the proprietary Rotoflex URC 2.0
control system, ensuring precise tension control and enhanced accuracy in die
cutting and slitting. In addition to higher quality output, speeds are
dramatically increased as well. The updated platform can now perform extremely
accurate slitting and die cutting at speeds up to 1000 fpm (305 m/min), a 30%
increase over production speeds of legacy DSI models.
Production managers will appreciate the versatility of this
new Rotoflex DSI as well. Idle equipment does not contribute to productivity,
and if a job only requires inspection and rewinding, die cutting equipment may
sit idle during that job run. The updated design of the Rotoflex DSI
accommodates a variety of inspection systems and the die cutting unit can be
disengaged for specific jobs, meaning it may be run as a slitter/rewinder or as
a die cutter, accommodating more applications and job types. This allows
production managers to better manage job mix and optimize workflows.
