Abstract
A gathering shoe is disclosed for combining glass filaments which have been attenuated from a bushing into a consolidated strand. The gathering shoe is formed of a porous material, preferably porous graphite, and has a central chamber or cavity within which is located gaseous fluid jets connected to a gaseous fluid supply. As gaseous fluid is forced through a slot in the porous shoe over which the glass filaments are combined into a unitary strand, the glass fiber strand rides on a gaseous fluid cushion. This decreases wear of the shoe and breakouts of the filaments caused by such wear and aids in drying the glass filaments.
