The Seiffert RollCheck® MAX is the laser system for aligning large rolls and rollers parallel in medium to large machines. You attach it with the supplied straps to rolls from 101 mm to 2.4 m in diameter, and measure over distances of 3 m or more. The bright green laser lines and the patented reflected laser beam show immediately whether the rolls are parallel.
We supply and rent out the RollCheck, and provide training with it. Prefer to have it measured? Our measurement service also aligns your rolls and rollers on site.
Features
For medium and large machines
Rolls from 101 mm to 2.4 m in diameter, over 3 m or more.
Green laser
A green laser line looks ten times brighter to the eye than a red one.
Patented reflected laser beam
The transmitter projects laser lines onto the reflector, which reflects them back to the transmitter. This shows you immediately whether the rolls are parallel.
Two angles at once
You see the vertical angle (pitch) and the horizontal angle (parallelism) at the same time, and adjust the roll directly.
One person, no training
One person aligns in a few minutes, without training.
Compact
Also fits in tight spaces; everything comes in a rugged case.
Crowned rolls too
Also suitable for measuring and aligning crowned rolls.
Less downtime and scrap
No more time-consuming trial and adjustment; this prevents rejects and lost production.
Rechargeable battery
Lithium-ion polymer battery (3.7 V, 4,000 mAh) for 16 to 20 hours of continuous use.
Applications
Paper and board
Aligning rolls and rollers of paper machines parallel.
Printing
Checking and aligning rolls in printing presses.
Film, plastics and textiles
Rolls in production lines for film, plastics and textiles.
Metal and food
Also in the metal and food industries.
Replacing rolls
After a roll change, the new roll is quickly parallel again.
