Inertial Measurement of Roller Parallelism - A New Approach to Solving an Old Problem

摘要

Web handling in converting - Roller parallelism as a frequent root cause Many web handling problems can be traced back to roller alignment issues. Symptoms range from fissures and creases in the product to vibrations in the machinery and, ultimately, to unscheduled stops in production, resulting in downtime and waste material. Benefits and limits of conventional alignment techniques While roller parallelism is reasonably easy to determine and to assure with conventional alignment methods, it has traditionally been hard to determine whether a given product quality or process quality issue can be traced back to roll misalignment. This is because traditional methods of aligning rolls depend on line of sight and a certain degree of proximity between rolls.
