In the operation of rolling mills, such as paper making or converting equipment, it is important to maintain alignment throughout the machinery. Alignment of components can influence web tracking, clothing tracking (wires, felts), premature hardware failure, power consumption, machine speed, etc. It is important to maintain acceptable alignment properties in all facets of a given machine.
In today's competitive environment, with quality and speed important issues, precision alignment is crucial to both production and maintenance. Optical instrumentation affords the ability to align machinery with a high degree of precision. Generally, a typical sheet or web fed machine can hold alignment tolerances within thousands on an inch. A broad rule of thumb is to maintain .001" per foot of role surface tolerance in the alignment of the machine. In other words this would allow a 10-foot roll to be out of alignment a maximum of .010". |
