Easy-Laser® E975 - Roll alignment

Quick and accurate roll alignment

System E975 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.

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 need 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 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.

Display unit E51

The display unit for the E series enables you to work more efficiently and for longer than ever before thanks to several innovative solutions. It is also ergonomically designed with easy-to-grip rubber cladding and robust construction.

 

Never lose power

The display unit is equipped with our Endurio™ Power management system. This ensures that you never have to stop in the middle of a measurement because the battery has run out.

Ergonomic design

The display unit has a thin, easy-to-grip and rubber coated profile that ensures a secure grip. It has large well-spaced buttons that give clear feedback when pushed. In addition, the two Enter buttons make the system suitable for both right and left-handed users. The display screen has clear graphics that guide you through the measurement process.

Personal settings

You can create a user profile where you can save your personal settings. You can also have different settings for different types of measurements. It makes work faster!

Language selection

You can choose the language that you want to appear on screen. English, German, French, Spanish, Portuguese, Swedish, Finnish, Russian, Polish, Dutch, Italian, Japanese, Korean and Chinese are available. 

Upgrading

If you wish to expand functionality in the future, the software in the display unit can be upgraded via the internet or by connecting a USB memory containing the new software. In this way you will also have access to the measurement programmes that we develop for new purposes in the future.

  1. Two Enter buttons, for left and right-handed users
  2. Large, easy to read 5.7” colour display
  3. Proper buttons for clear feedback
  4. Thin profile gives a perfect grip for your hands

Detector E2 with roll centering bracket

System E975 has an angle detector (E2) which is mounted on a special roll centering bracket. The standard bracket can be used for diameters 80–400 mm [3.1–15.8"], and a minimum length of 300 mm [11.8"]. Accessory brackets for other dimensions are available on request. Depending on situation the units can be mounted in different ways on the bracket to allow for measurement (see illustration to the right).

  2. Mounting holes (x2)

D22 Laser transmitter

Laser transmitter D22 can be used to measure flatness, straightness, squareness, level and parallelism. The laser beam can sweep 360° with a measurement distance of up to 40 metres [130´] in radius. The laser beam can be angled 90° to the sweep, within 0.01 mm/m [0.01 mils/inch].

The transmitter has many mounting options. Attach it with the three magnetic feet, horizontally or vertically. Attach it with a pin in the spindle. Or put it beside the machine on for example a tripod (optional).
