ABSTRACT:
A contamination gauge for paper manufacturing for detecting the debris on paper includes a hand-held housing having a gripping surface and a plunger carried axially by the housing having a pressure application surface disposed on one end of the plunger for applying a predetermined force. A force exerting element is carried within the interior of the housing for exerting the predetermined pressure when the housing is moved relative to the plunger. An indicator indicates when the housing has moved sufficiently for generating the predetermined amount of pressure. Also a method for testing the propensity of paper rolls to lint debris on printing machines is disclosed.
