Crack detection cuts paper-mill downtime

摘要

Marietta, GA—When a paper roll tears, large paper mills can lose as much as 30 minutes to downtime at costs approaching $1,000 per minute. To eliminate that problem, engineers from Ryeco Inc. have devised a system that detects tiny cracks in paper rolls moving as fast as 8,000 feet per minute. Using the system, mill operators can detect edge cracks as small as 1/16 inch. As a result, they can fix an edge crack before the tear grows larger, ultimately preventing downtime.
