    摘要: A spinnerette has an extrusion crucible provided with extrusion nozzles in its bottom wall, and a melting crucible atop the extrusion crucible. The melting crucible is bounded in longitudinal direction by walls having arcuately curved wall segments so that the interior of the melting crucible is composed of a plurality of generally cylindrical compartments which are arranged side by side in the longitudinal direction and which open into one another where they adjoin each other.

    摘要: Glass tablets which are to be introduced seriatim into an elongated melting chamber of a crucible having orifices for extrusion of glass filaments are stored in a magazine and are fed onto the first section of a first vibrating trough whose sections have different inclinations. The last section of the first trough discharges tablets into the receptacle of a weighing device which accumulates a predetermined number of tablets and thereupon discharges the accumulated batch of tablets onto the first section of a second vibrating trough the last section of which discharges tablets into an elongated hopper registering with the open top of the melting chamber. At least the last section of the second trough is inclined downwardly toward the hopper to such an extent that tablets leaving the preceding section of the second trough are accelerated during travel in the last section and enter the hopper at timely spaced intervals. The second trough is caused to swivel back and forth so that its last section discharges tablets into different portions of the hopper.
