Abstract

PURPOSE:To perform stable and sure threading work by providing a threading pipe having a slit on the side wall of a furnace over the entire length of the furnace, fitting a wire conveying body detaining one end of a wire into the pipe and running this by fluid pressure. CONSTITUTION:When a strip 14 breaks during its heat treatment, both ends are pulled to the outside of the furnace 1, and a wire conveying body 5 is fitted to one end of a threading pipe 2 provided over the entire length of the furnace. The end part of a wire 10 from a unwinding device 11 is detained to a wire detaining means 6, and a fluid pressure feeder 8 is coupled to the end part of the threading pipe 2. Here, when the feeder 8 is driven to supply compressed fluid into the threading pipe 2, the wire conveying body 5 travels in the pipe owing to fluid pressure and therefore the wire 10 is let off from the unwinding device 11 and is passed through the furnace 1 inside. A threading hoop 13 is passed by this wire 10.
