PURPOSE: To provide an apparatus for improving operation efficiency and reducing risk of safety accident by automatically guiding the needle for threading to annealing furnace in the state that a needle for threading is centrally aligned. CONSTITUTION: In an apparatus for guiding a threading object(66) mounted needle(69) to an annealing furnace(10) comprising a central curtain member(11) opened and closed by operation of lever, and a lower driving roll(17) mounted on the lower side of the central curtain member and rotated by receiving driving force, the apparatus(100) for centrally aligning and guiding a needle for threading to the annealing furnace comprises a clutch assembly(20) mounted on a fixed base mounted on a position adjacent to the annealing furnace and a sliding base slidingly mounted on the fixed base by driving of a cylinder member(27) to transmit driving force of the lower driving roll; a wire member(30) one end of which is connected to the sliding base, and the other end of which is mounted on the lever of the central curtain member to pull the lever of the central curtain member by driving of the cylinder member during movement of the sliding base so that the central curtain member is opened or closed; a support(50) mounted on a vertical extension line of the central curtain member of the annealing furnace; support roll members which are rotatably and longitudinally mounted on the support and formed in a cylindrical shape, the inside of which is hollow, and on a certain position of a length direction of which a catching projection formed through hole is formed so that a sliding member is mounted around the catching projection of the through hole; a hollow connecting body which is mounted on a hollow part of the support roll members, on which a protrusion part is formed to press one end of the sliding member so that the sliding member is projected, at one side of which an indented rectangular groove is formed, and in which a hollow part is formed; a pin insertion member(55) which are mounted on the longitudinal side surface of the support such that the pin insertion member is slid by operation of a pin inserting cylinder member, and on which a plurality of pin members(53) inserted into the rectangular grooves are mounted; a plurality of support roll rotary shafts which are rotatably mounted on the hollow part of the hollow connecting body and extended to one side to be mounted on the support, and interlocked by driving of a chain member(83); and a second driven shaft clutch(85) mounted on a rotary shaft of one of the support rolls adjacent to the annealing furnace and connected to the clutch assembly to transmit driving force to rotary shafts of the plurality of support rolls.
