Abstract

Abstract A CELLULAR PLANK IS MADE BY CONTINUOUSLY PULLING A BAND OF CELLULAR MATERIAL FROM A SUPPLY OF THE MATERIAL. AS THE BAND IS PULLED, ADHESIVE IS APPLIED TO ITS UPPER, LOWER AND SIDEWISE FACES. IT IS THEN DIRECTED INTO A FOLDER WHICH ALSO RECEIVES A STRIP OF WRAPPING MATERIAL FROM A SUPPLY. BEFORE THE WRAPPING MATERIAL ENTERS THE FOLDER, IT IS SCORED ALONG LINES WHICH WILL REGISTER WITH THE FOUR CORNERS OF THE CELLULAR BAND. THE WIDTH OF THE SCORED STRIP IS EQUAL TO THE PERIMETER OF AN ORTHOGONAL CROSS SECTION OF SAID BAND. THEN AS THE BAND AND THE WRAPPER PASS THROUGH THE FOLDER, THE LATTER IS WRAPPED ABOUT THE FORMER SO AS TO BE ADHERED TO IT BY MEANS OF THE ADHESIVE. AFTER THE COMBINED MATERIAL LEAVES THE FOLDER AND THE ADHESIVE HAS SET, IT IS IN THE FORM OF A WRAPPED PLANK WHICH IS THEN CUT INTO APPROPRIATE LENGTHS FOR STRUCTURAL USE. A PREFERRED FORM IS THAT OF A BLOCK. IN SOME CASES SEVERAL STRIPS ARE EMPLOYED FOR WRAPPING THE BLOCKS BUT IN ANY EVENT THE WRAPPER COVERS THE TOP, BOTTOM AND TWO SIDES OF THE BLOCK LEAVING THE END FACES OPEN. THE PREFERRED FROM OF CELLULAR MATERIAL IS OF THE HONEYCOMB TYPE, ALTHOUGH IT IS CONTEMPLATED THAT A POLYURETHANE OR OTHER LIKE FOAM MATERIAL MAY ALSO BE EMPLOYED.
