Reduction of Paper Breaks for UCW 51-60 run (Low Basis Weight)
From Jan 2009 to April 2009 , due to frequent occurrences of Sheet breaks, it was considered as a major contributor for Lost Time, with 38% shared percentage from the total loss time. • Graphical representation below : • 1.1 will show frequency of Sheet breaks occurrence. • 1.2 will show total duration (accumulated min) of sheet breaks for the specified period of • 4 months Graph 1.1 Graph 1.2
Also, with the occurrence of Sheet breaks, quality of paper is affected. Below are graphs showing rejects and sheet breaks….
