ABSTRACT:
A glass-wool mat is produced from a sheet of glass fibers by heating the surfaces of the sheet to a temperature close to the melting point of glass so that the glass fibers in the surface area have rounded ends and are shrunk so that they are firmly entangled together. Thus, non-irritating surfaces are provided on the mat.
