Measuring and comparator device

Claim 1

AN ELEMENT FOR USE WITH A PAIR OF RESILIENT ADHESIVE TAPES FOR MEASURING AND PERMITTING ADJUSTMENT OF THE DYNAMIC COMPRESSIVE FORCE EXERTED BY A PAIR OF PRESSURE ROLLS HAVING DEFORMABLE SURFACES, COMPRISING AN ELONGATED, THIN, GENERALLY RECTANGULAR, PLATE-LIKE SUPPORT COMPONENT OF A GIVEN THICKNESS, AN ELONGATED SLOT OF GIVEN LENGTH AND WIDTH CHARACTERISTICS FORMED IN SAID PLATE-LIKE SUPPORT ELEMENT SO AS TO EXTEND LONGITUDINALLY THEREOF THROUGHOUT A DISTANCE WHICH IS AT LEAST EQUAL TO THE CIRCUMFERENCE OF ONE OF SAID PRESSURE ROLLS, AND A SCALE COMPRISING A PLURALITY OF INDEX MARKS POSITIONED ALONG SAID ELONGATED SLOTS RELATING TO THE COMPRESSION OF A SHEET MATERIAL TO BE PASSED BETWEEN SAID PRESSURE ROLLS, SAID SUPPORT COMPONENT BEING ADAPTED TO HAVE SAID TAPES SO AFFIXED TO EACH OF ITS OPPOSITE SURFACES, IN GENERALLY ALIGNED RELATION, AS TO COVER BOTH SIDES OF SAID ELONGATED SLOT, SAID ELEMENT, WHEN PASSED ENDWISE BETWEEN SAID PRESSURE ROLLS, DERIVING THEREFROM A MUTUAL PROGRESSIVE ADHESION OF SAID TAPES WITHIN A GIVEN LIMITED AREA OF SAID ELONGATED SLOT, THUS FORMING A TEST PATTERN IN SAID TAPE WHICH IS DETERMINED AS TO ITS LENGTH, WIDTH AND CONFIGURATION BY THE WIDTH AND DEPTH CHARACTERISTICS OF SAID SLOT, BY THE SURFACE CHARACTERISTICS OF SAID PRESSURE ROLLS, AND BY THE DYNAMIC COMPRESSIVE FORCE EXERTED BY SAID PRESSURE ROLLS, SAID TEST PATTERN BEING READABLE IN TERMS OF THE INDICIA OF SAID SCALE AND RELATING TO SAID DYNAMIC COMPRESSIVE FORCE.
