Abstract
|
Editorial: Since the early 1930s, the process of melting glass and subsequently forming fibers, in particular discontinuous fiber glass or continuous glass filaments, evolved into commercial-scale manufacturing. Most commonly, a direct melt process is applied. Thereby, the several raw materials were mixed, fed into a furnace, melted and forwarded to the fiber-forming units. Here, the filaments are formed by passing a bushing plate with a certain number of nozzles. Both the number of nozzles as well as its design may vary. Arrangements of 4000 or 8000 nozzles frequently occur. The bushing plate is the most important and expensive part of the machinery for glass fiber processing. The bushings are heated electrically and their temperatures are precisely controlled to maintain a constant viscosity of the glass melt. A high-speed winder catches the filaments at a circumferential speed, which is much faster than the molten glass that exits the bushings. Thus, a tension is applied to the filaments.
