Abstract (en)
[origin: JPH0592205A] PURPOSE: To lay a winding wire formed from a laying bed with a small pitch without being affected by the elasticity caused by the material property and the diameter of the wire by a twisting forming device of a curving pipe for twisting the wire under positive locking and frictional engagement. CONSTITUTION: A roller table 23 is arranged at the rear part of a laying pipe 14 in the conveying direction of the wire 1 and the winding wire 24 is laid on the roller table 23. The wire 1 is cooled on this roller table 23 and conveyed to a coil forming chamber successively disposed. The twisting device 5 disposed at upstream side of the laying pipe 14 is rotated at the pre-selected angular velocity so that the wire coming in the laying pipe 14 already has a prescribed twist. In this way, the twist work added to the wire 1 as the whole body is increased so that the winding wire can be laid in the mutually approaching state, i.e., the pitch of spiral formed with the winding wire 24 is a very small and thus, the conveying on the roller table and the following formation into a coil can easily be executed.
