PURPOSE: To enhance the speed of, and automate, an operation requiring skill, by combining a contoured plate having a surface shape conforming to the shape of a line connecting the centers of guide holes, a spit array comprising a plurality of springy spits with a spit width equal to the difference between the pitch of the guide holes and the diameter of the wires, and pushers for pushing outer. ost ones of the spits.

CONSTITUTION: A surface of a contoured plate 5 to be brought into contact with wires 1a... is so contoured as to conform to the shape of a line connecting the centers of guide holes 2a... On the surface of the contoured plate 5, an array 4 of spits filled to a base 3 are projected in a cantilever like condition. The spits 4s... in the spit array 4 are springy, the diameter of the spits 4a... is equal to the spacing between the peripheries of the guide holes 2a..., and the pitch of the spits 4a... is so set that one of the spits 4a... is fitted between each adjacent pair of the wires 1a... under the condition where the wires 1a... are located at retracted positions, namely, initial arranging positions. Pushers 6a, 6b are disposed on the outer side of outermost ones 4a, 4f of the spits 4 so that they can be operated in X-directions. The pushers 6a, 6b are provided at tip parts thereof with notched parts 7a, 7b for pushing the wires 1a, 1d.
