L-742 Ultra Precision Roll Alignment System

L-742 Ultra Precision Roll Alignment System > Printing Press & Paper Mill Roll Alignment The L-742 Ultra-Precision Dual Scan® Laser provides 2 automatically rotating laser planes for even the most difficult roll alignment applications. It is a very affordable yet powerful laser alignment system that will not only MEASURE but also FIX roll misalignment on almost any kind of paper mill or process mill, all in a fraction of the time of laser transits and theodolites. Hamar laser systems are up to 3 times faster and up to 10 times more accurate than conventional optical alignment tools! > More Accurate Alignment Increases Material Flow and Quality With poor roll alignment, most machines, whether a film line or paper mill, will produce a product that has wrinkles and other quality problems. The material will also wander or " walk" to one side of the roll or the other, all which leads to significant downtime and potentially tons of scrapped product. Typically, the only remedy is to call the local service company to bring the transits or theodolites or to try using tram bars and inside micrometers, all of which are very time-consuming, sometimes not very accurate, and costly. The L-742 Roll Alignment System, by contrast, is so accurate and easy to use that you can set the rolls parallel correctly the first time, saving enormous costs in reduced downtime, scrapped product and quality problems. In fact, most machines that can handle it can run at faster speeds after laser alignment. In many cases, this increased productivity will pay for the laser in a matter of months. > L-742 Significantly Simplifies Roll Parallelism Checks The L-742 is so easy to use its operation usually requires only one technician. With 2 automatically rotating laser planes, each with a range of 100 feet ( 30.5 meters) in radius, rolls alignment at multiple elevations can easily be achieved with one setup at each machine section. The setup process is easy and fast because we use timesaving and simplifying features like our ALIGN mode in the R-1310 PDA Readout. The feature compares one target reading to another, calculating the difference between the two. This allows the user to adjust the roll until the " difference" reading is zero instead of having to perform manual calculations. It also is a great time saver for the bucking-in ( laser setup) process. It also is a great time saver for the bucking in process.. > High Accuracy Reduces Optics' Guesswork Hamar Laser' s L-742 Roll Alignment System is accurate to + / -.003" ( .06 mm) in 200 feet ( 61 meters) under good atmospheric conditions. This accuracy turns the alignment process from an art using laser transits or theodolites to a science using lasers. Optics are considered an art because each operator " sees" the readings differently and essentially has to make an educated guess as to the correct number. In fact, it is rare that any 2 optics technicians will get the same numbers. With the L-742, this guesswork is essentially eliminated because the target electronics determine the alignment reading. And it is very repeatable from one operator to the next, unlike transits or theodolites! > Factory-Built Benchmark Fixturing The L-742 Roll Alignment System comes with accessory fixtures to pick up floor benchmarks for aligning the laser to the machine' s centerline. The L-742 also has the flexibility to easily use the reference roll to set up temporary offset centerlines. In fact, this is our preferred method of referencing the machine' s centerline, as benchmarks are frequently in as poor shape as the floor they sit in. Cracks in the floor can seriously affect the position of the benchmarks and often result in poor roll alignments. > Laser Planes Have 200-Foot Range One of the most powerful features of the L-742 is the automatically rotating laser plane with 100-foot ( 30.5 meters) range in radius. That means rolls, at almost any elevation, can be measured simultaneously without having to move the laser vertically. This also allows the laser to be moved to more sections without having to change the location of the reference targets. > Competitive Systems Use 10-Year Old Technology Our competitors' roll alignment laser systems use point-and-shoot laser technology, along with remote beam-bending devices that are difficult to set up, are not very accurate and relocate. We abandoned that laser technology 10 years ago with the introduction of our multi-plane, continuously rotating lasers. Not only is point-and-shoot technology difficult to set up, it also requires extra manpower and about 50% more time. > Less Manpower Needed for Alignments The L-742 Roll Alignment System reduces the alignment team manpower. Wireless targets and automatically rotating laser planes make setting up the laser at each machine section much easier, requiring only one operator. The wireless readout displays both targets simultaneously, allowing the user to quickly reference the benchmarks. Traditional optics, like transits and theodolites, usually require at least one man holding a reference target in both reference locations. > No Need for Theodolites’ Time-Consuming Recalibration after Plumb Measurements Unlike optics that usually require recalibration of the levels each time plumb is checked, the L-742 can simultaneously check level and plumb from a single setup. The levels usually only require calibration once a month or so and can easily be checked in the field with a simple 10-minute procedure.
