Laser Gyro Alignment at CMM
As an engineer, sometimes you trip across something that gives you that "best invention since slice bread" feeling. Well, there is one at CMM that your should take a peak at.
Laser gyro roller alignment.
The Paralign(tm) from Pruftechnik looks like it could fly a helicopter. You "sweep" one roller as your reference, send the date wirelessly to a laptop, then continue "sweeping" other rollers in your web line to get tram and level errors from the reference roller. Their literature says it is accurate to 0.4 mils per foot, which should exceed most converters needs. The system is fast, so you can do many, many rollers with minimum downtime. Whether the cost of this service can be justified for you operation is based on what downtime costs you.
The folks at Pruftechnik has brought this new device to the US. They are back in a corner booth at the show, so you may not have notice them, but please do. Also, get info at their website:
