SPINNERET FEEDER TO EXTRUDE GLASS FIBRES BY ONE STAGE METHOD Russian patent published in 1995 - IPC

Abstract RU 2031867 C1

FIELD: glass fibre production. SUBSTANCE: spinneret feeder to extrude glass fibres by one stage method has formed by side and butt walls body, spinneret plate, neck, lid and rigidly fixed inside the body heater. Neck is made with rigidly fixed hollow distributing cone with holes. Cone is turned by its vertex to spinneret plate and holes are uniformly located on side surface and spaced by (0.4 - 0.9) L from vertex of cone to centers of holes with L - length of generatrix. Heater is mounted with inclination down to butt walls and made in the form of V-shaped baffle and lid is mounted with inclination upward from butt walls to neck. Ratio of total areas of holes in distributing cone , heater and spinneret plate is (1.05 - 1.2) : (1.05 - 3) : !. EFFECT: spinneret feeder to extrude glass fibres by one stage method is used in glass fibre production. 3 dwg
