Abstract

765,632. Glass fibres. LOOSLI, H. March 11, 1955 [March 12, 1954], No. 7278/55. Drawings to Specification. Class 56 The die hole through which molten glass passes in the making of glass fibres is formed in a tungsten strip. The strip is electrically heated, and its supports are cooled. The strip, at least in the vicinity of the die'hole, is surrounded by an inert gas.
