Abstract

Wire Mark is the impression left on the paper web by its initial forming fabric. Wire Mark can be explained as differing levels of density in a sheet. By definition, the ideal formation is a sheet which has completely uniform density. Many changes have occurred in forming fabrics over the years to resolve this problem. The development of double and triple layer wires for a smoother surface have come about. This thesis takes these forming wires and further modifies the surfaces to reduce wire mark patterns. The action is analyzed by several common paper tests, along with the aid of the M/K formation tester and the densitometer. The results from the M/K formation test show that there is a good possibility that the modification does some reduction and that this is an area which deserves more attention.
