Classification description:

Manufacture or treatment of flakes, fibres, or filaments from softened glass, minerals, or slags; Manufacture of glass fibres or filaments; Manufacture of preforms for drawing fibres or filaments made entirely or partially by chemical means, e.g. vapour phase deposition of bulk porous glass either by outside vapour deposition [OVD], or by outside vapour phase oxidation [OVPO] or by vapour axial deposition [VAD] by glass deposition on a glass substrate, e.g. by inside-, modified-, plasma-, or plasma modified- chemical vapour deposition [ICVD, MCVD, PCVD, PMCVD], i.e. by thin layer coating on the inside or outside of a glass tube or on a glass rod; Means for supporting, rotating and translating tubes or rods being formed, e.g. lathes Deposition substrates, e.g. tubes, mandrels
