Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
THE METHOD OF FORMING A MULTIPLE-PLY ARTICLE, WHICH COMPRISES FUSING A FLEXIBLE SHEET OF POLYETHYLENE TO ONE SURFACE OF A FLEXIBLE SHEET OF RELATIVELY CLOSELY WOVEN FABRIC OF DISSIMILAR MATERIAL UNDER HEAT AND PRESSURE TO SOFTEN THE POLYETHYLENE AND CAUSE IT TO PENETRATE INTO THE MESHES OF THE FABRIC AND THUS UNITE SAID SHEETS, SAID POLYETHYLENE PENETRATING ONLY PARTIALLY THROUGH SAID FABRIC TO LEAVE THE OPPOSITE SURFACE THEREOF EXPOSED, AND THEN ADHERING THE SAID EXPOSED FABRIC SURFACE OF THE RESULTING TWO-PLY FABRIC-POLYETHYLENE UNIT TO THE SURFACE OF ANOTHER PLY OF FABRIC WITH AN INTERPOSED ADHESIVE.

Claim 3
Dependent Claim
134 words
AS A NEW ARTICLE OF MANUFACTURE, A MULTIPLEPLY ARTICLE COMPRISING A SUBSTANTIALLY RIGID PANEL FORMED OF A PLURALITY OF LAYERS OF GLASS FABRIC ADHESIVELY BONDED TOGETHER IN SUPERIMPOSED RELATION, AND A FLEXIBLE TWO-PLY LAMINOUS UNIT COMPRISING A LAYER OF POLYETHYLENE OF MOLECULAR WEIGHT BETWEEN ABOUT 5,000 AND ABOUT 100,000 MECHANICALLY SECURED COEXTENSIVELY TO ONLY ONE SURFACE OF A SINGLE SHEET OF GLASS FABRIC BY INTRUSIONS OF SAID POLYETHYLENE EXTENDING INTO AND ONLY PARTIALLY THROUGH THE MESHES OF SAID SINGLE GLASS FABRIC SHEET, WHEREBY THE OPPOSITE SURFACE OF SAID SHEET IS FREE OF SAID POLYETHYLENE, SAID POLYETHYLENE-FREE OPPOSITE GLASS FABRIC SURFACE OF SAID TWO-PLY LAMINOUS UNIT BEING ADHESIVELY BONDED TO ONE GLASS FABRIC SURFACE OF SAID PANEL WITH THE POLYETHYLENE LAYER OF SAID TWO-PLY LAMINOUS UNIT AFFORDING AN OUTER SURFACE OF THE COMPLETE MULTIPLE-PLY ARTICLE.
