Easy-Laser E975 - Roll alignment

The E975 system is designed mainly for roll alignment. It is well suited when just one or two rolls are to be replaced or adjusted at the same time. Because the system is so quick to set up on the machine, even a short planned production stop can be utilized to measure a roll, and maybe replace or adjust it.

Quick and accurate roll alignment

Easy-Laser® E975 Roll alignment is designed for replacement and alignment of rolls in, for example, printing presses, paper machines, and converting machines.

Take advantage of short downtimes

Thanks to the fact that the system is quick to set up on the machine it can be used during short stoppages to check and if necessary adjust or replace a roll. Where more advanced methods might require that the measuring service is scheduled some time in advance and use contracted personnel, with Easy-Laser® E975 you can do the job yourself. And other methods such as measurement with prisms along the machine often take significantly longer to prepare. You quite simply have better control over your machine time and increase productivity using Easy-Laser® E975!

High precision is required for the ever faster machines of today

In order to maintain the quality requirements of the ever faster machines of the present day, alignment tolerances have needed to be set very tight. This also means that the measurement equipment must also have the greatest possible precision. Only then can the highest quality be assured!

Easier and more reliable measurement method

The system consists of a laser transmitter, a display unit with guiding software, and a compact and neat detector unit positioned on the roll. No stand is used to the side of the machine, which eliminates the risk of the reference (laser beam) being moved accidentally. No consideration needs to be taken of any machine protection and frames on the side of the machine since the laser transmitter is positioned on the inside of the roll package. The system's display unit produces a PDF report directly on site. The result can also be transferred to the PC.

Alignment of rolls with Easy-Laser® E975

Pays off quickly

Compared to many competing methods, Easy-Laser® E975 is a cost-efficient solution for any company, which means that the investment is quickly repaid through the reduced number of unplanned operational stoppages and longer service lives for wear parts. Maintenance departments and service firms can also extend the measurement system to cover other alignment solutions in the Easy-Laser®-range.
