Abstract: A METHOD FOR CONTINUOUSLY ATTACHING A LENGTH OF MAGNETICALLY ATTRACTABLE MATERIAL TO A LENGTH OF A NON-MAGNETICALLY ATTRACTABLE MATERIAL. THE MAGNETICALLY ATTRACTABLE MATERIAL RESTS IN CONTACT WITH AND ADJACENT TO THE OTHER MATERIAL, BOTH BEING MOVED IN UNISON ALONG A SUPPORT. ADHESIVE IS APPLIED AT SELECTED CONTACTING POSITIONS OF THE MAGNETICALLY ATTRACTABLE MATERIAL AND THE OTHER MATERIAL WHERE THE TWO MATERIALS MOVE PAST THE INLET END

OF THE SUPPORT. AN AIR BLAST SHAPES AND COOLS THE ADHESIVE IMMEDIATELY AFTER IT IS APPLIED. MAGNETS IN THE SUPPORT DRAAW THE MAGNETICALLY ATTRACTABLE MATERIAL AGAINST THE OTHER AND MAINTAIN THE TWO MATERIALS IN A FIXED, ADJACENT RELATIONSHIP. THE ADHESIVE SETS AS THE TWO MATERIALS MOVE TO THE DISCHARGE END OF THE SUPPORT.
