Title:
FIBRE PRODUCTION DEVICE AND FIBRE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/018861
Kind Code:
A1
Abstract:
A fibre production device is provided with: a storage tank (1) which stores a molten starting material (10); an electric heater (2) which heats the storage tank (1); a non-contact thermometer (9) which measures the temperature of the molten material (10); a temperature control unit (8) which is provided between the electric heater (2) and a power source (6) for the electric heater, and controls the electric heater (2) on the basis of the results of measurement by the non-contact thermometer (9) and adjusts the temperature of the molten material (10); a nozzle (3) which ejects the molten material (10) inside the storage tank (1); a collector (4) which collects fibres (11); a voltage generator (5) which electrically charges the molten material (10); and an insulating transformer (7) placed between the temperature control unit (8) and the electric heater (2). The insulating transformer (7) is placed between the electric heater (2) and the power source (6) for the electric heater and temperature control unit (8), creating a closed circuit, and therefore high voltage does not flow to the power source (6) for the electric heater or the temperature control unit (8). Because of this, the device is not prone to damage, and it is simple to achieve stable fibre production.
