Exact Defect Marking

In finishing processes it is very often necessary to know the exact position of defects which have been detected already in an earlier process. However, slippage between rollers and material as well as different web forces make it difficult if not impossible to trace these defects correctly. The marking system ELMARK from Erhardt + Leimer offers the right solution. Defects are marked reliably by labels being applied on the web edge. The way the labels are applied and the special nature of the labels guarantee that the labels remain in their position reliably and for a long time.
