THE METHOD OF PRODUCTING A METAL-FACED MAT OF MINERAL FIBERS INCLUDING CONTINUOUSLYADVANCING A MAT OF MINERAL FIBERS IN WHICH THE FIBERS ARE PREBONDED IN THE MAT, CONTINOUSLY ADVANCING A LAYER OF METAL FOIL FROM A SUPPLY IN A DIRECTION SUBSTANTIALLY PARALLEL TO AND OPPOSITE TO THE DIRECTION OF MOVEMENT OF THE ADVANCING MAT, FEEDING POWDERED BINDER ONTO THE UPPER SURFCE OF THE LAYER OF FOIL, PASSING THE LAYER OF FOIL AROUND AND IN DIRECT CONTACT WITH A CURVED SURFACE TO CAUSE THE LAYER OF FOIL TO ADVANCE IN THE SAME DIRECTION AS THAT OF THE MAT, HEATING THE CURVED SURFACE,TRANSFERRING HEAT FROM THE CURVED SURFCE TO THE LAYER OF FOIL BY CONDUCTION TO DISPERSE THE BINDER OVER THE SURFACE OF THE LAYER OF FOIL, ENGAGING THE BINDER-BEARING SURFACE OF THE LAYER OF FOIL WITH A MAJOR SURFACE OF THE MAT WHILE THE LAYER OF FOIL ASSEMBLY OF MAT AND FOIL LAYER TO A CURING STATION AND APPLYING ADDITIONAL HEAT AT SAID STATION TO CURE THE BINDER AND ADHERE THE LAYER OF FOIL TO THE MAT.
