Beschreibung
Zusammenfassung:	The invention refers to a feeding device for feeding an optical fiber from a coil and for recoiling unused fiber for use in an apparatus for measuring the temperature of a melt. The device comprises a support for a coil, a feeding mechanism for decoiling the optical fiber from the coil and recoiling the optical fiber and at least one motor for driving the feeding mechanism. It is the object of the present invention to avoid blockage when decoiling and recoiling a fiber from a coil of a feeding device for feeding an optical fiber. The object of the invention is solved by a device for feeding an optical fiber from a coil and for recoiling unused fiber. The device comprises a support for a coil, a feeding mechanism for decoiling an optical fiber from the coil and recoiling the optical fiber and at least one motor for driving the feeding mechanism. The device comprises a load for the optical fiber which avoids a spring back effect of the optical fiber from the coil. As a result, a blockage is avoided when decoiling and recoiling the fiber.
