Thermoplastic rod adhesives and method of bonding metallic sheet material therewith

Claim 1

AS A NEW ARTICLE OF MANUFACTURE, A SUPPLY BODY OF SOLIDS HEAT SOFTENABLE ADHESIVE REDUCIBLE PROGRESSIVELY BY HEAT TO A FLUID CONDITION IN QUANTITIES AS NEEDED FOR USE IN A DIRECT THROUGH FEED INUSTRIAL CEMENT APPLYING AND DISPENSING SYSTEM, SAID SUPPLY BODY COMPRISING A COIL HAVING A PLURALITY OF TURNS UNIFORM ROD COMPOSED OF A HEAT SOFTENABLE INTIMATE CONTAINING FROM 10% TO 30% BY WEIGHT OF AN EXPOXY RESINOUS GLYCIDYL POLYETHER CONTAINING TERMINAL EXPOXY GROUPS AND FROM 90% TO 70% BY WEIGHT OF HEAT SOFTENABLE RESINOUS MATERIAL CONTAINING POLYMETERIAL AS A MAJOR COMPONENT, SAID RESINOUS MATERIAL BEING SUBSTANTIALLY NONREACTIVE WITH SAID EPOXY RESINOUS GLYCIDYL POLYETHER, THE CROSS SECTION OF SAID ROD BEING FROM 1/8" TO 1/4" IN THICKNESS, THE PHYSICAL PROPERTIES OF SAID ROD INCLUDING THE CHARACTERISTICS THAT SAID ROD IS SELF SUPPORTING, DRY, AND SUFFICIENTLY STIFF TO BE FED LINGITUDINALLY BUT ADEQUATELY FLEXIBLE TO BE COILED FOR STORAGE AND UNCOILED FOR USE AS NEEDED WITHOUT CRACKING.

Claim 3

A METHOD OF BONDING A METAL WORK SURFACE TO ANOTHER SURFACE COMPRISING THE STEPS OF PROVIDING A SLENDER, SELF-SUPPORTING ROD OF SOLID ADHESIVE COMPRISING A HEAT SOFTENABLE INTIMATE MIXTURE OF FROM 10% TO 30% BY WEIGHT OF AN EPOXY RESINOUS GLYCIDYL POLYETHER CONTAINING TERMINAL EPOXY GROUPS AND FROM 90% TO 70% BY WEIGHT OF HEAT SOFTENABLE RESINOUS MATERIAL CONTAINING POLYETHYLENE AS A MAJOR COMPONENT, SAID RESINOUS MATERIAL BEING INCOMPATIBLE IN FLUID CONDITION AND SUBSTANTIALLY NONREACTIVE WITH SAID EPOXY CONDITION AND SUBPOLYETHER, THE PHYSICAL PROPERTIES OF SAID ROD INCLUDING THE CHARACTERISTICS THAT SAID ROD IS DRY AND SUFFICIENTLY STIFF TO BE FED LONGITUDINALLY FOR USE AS NEEDED TO SUPPLY ADHESIVE MATERIAL, THE CROSS SECTION OF SAID ROD BEING SUBSTANTIALLY UNIFORM, INTRODUCING A FORWARD PORTION ONLY OF SAID ROD OF ADHESIVE INTO AN ELONGATED HEATING ZONE, CONFINING THE ADHESIVE IN SAID HEATING ZONE TO A CROSS SECTIONAL AREA NOT SUBSTANTIALLY GREATER THAN THE CROSS SECTIONAL AREA OF SAID ROD, APPLYING HEAT TO SAID FORWARD PORTION OF THE ROD TO SOFTEN SAID PORTION ONLY OF THE ADHESIVE ROD TO FLUID CONDITION, PROGRESSIVELY INTRODUCING FURTHER PORTIONS OF THE ADHESIVE ROD INTO THE HEATING ZONE TO INSURE ORDERLY MOVEMENT OF ADHESIVE IN INTIMATELY MIXED CONDITION THROUGH SAID HEATING ZONE, TRANSFERRING FLUID ADHEZIVE FROM THE HEATING ZONE TO SAID WORK SURFACE WHILE STILL IN INTIMATELY MIXED CONDITION AND PRESSING SAID OTHER SURFACE AGAINST THE ADHESIVE ON SAID WORK SURFACE.

Claim 4

A METHOD OF BONDING A METAL WORK SURFACE TO ANOTHER SURFACE COMPRISING THE STEPS OF PROVIDING A SLENDER, SELF-SUPPORTING ROD OF SOLID ADHESIVE COMPRISING A HEAT SOFTENABLE INTIMATE MIXTURE OF FROM 10% TO 30% BY WEIGHT OF AN EPOXY RESINOUS GLYCIDYL POLYETHER CONTAINING TERMINAL EPOXY GROUPS AND FROM 90% TO 70% BY WEIGHT OF HEAT SOFTENABLE RESINOUS MATERIAL CONTAINING POLYETHYLENE AS A MAJOR COMPONENT, SAID RESINOUS MATERIAL BEING INCOMPATIBLE IN FLUID CONDITION AND SUBSTANTIALLY NONREACTIVE WITH SAID EPOXY CONDITION AND SUBPOLYETHER, THE PHYSICAL PROPERTIES OF SAID ROD INCLUDING THE CHARACTERISTICS THAT SAID ROD IS DRY AND SUFFICIENTLY STIFF TO BE FED LONGITUDINALLY FOR USE AS NEEDED TO SUPPLY ADHESIVE MATERIAL, THE CROSS SECTION OF SAID ROD BEING SUBSTANTIALLY UNIFORM, INTRODUCING A FORWARD PORTION ONLY OF SAID ROD OF ADHESIVE INTO AN ELONGATED HEATING ZONE, CONFINING THE ADHESIVE IN SAID HEATING ZONE TO A CROSS SECTIONAL AREA NOT SUBSTANTIALLY GREATER THAN THE CROSS SECTIONAL AREA OF SAID ROD, APPLYING HEAT TO SAID FORWARD PORTION OF THE ROD TO SOFTEN SAID PORTION ONLY OF THE ADHESIVE ROD TO FLUID CONDITION, PROGRESSIVELY INTRODUCING FURTHER PORTIONS OF THE ADHESIVE ROD INTO THE HEATING ZONE TO INSURE ORDERLY MOVEMENT OF ADHESIVE IN INTIMATELY MIXED CONDITION THROUGH SAID HEATING ZONE, TRANSFERRING FLUID ADHEZIVE FROM THE HEATING ZONE TO SAID WORK SURFACE WHILE STILL IN INTIMATELY MIXED CONDITION AND PRESSING SAID OTHER SURFACE AGAINST THE ADHESIVE ON SAID WORK SURFACE.
