Referring to Fig. 1, the wire guide device 3' for pay-off is installed on the incoming reel side of the pay-off reel 2' of the tension machine. When the tension is paid off, the wire 1' on the wire reel is guided by the wire guide device 3' for pay-off. After being guided, it enters the pay-off reel 2' to ensure that the wires entering the pay-off reel 2' do not change jobs.

Referring to Figures 2 to 4, the wire guide device for pay-off of the tensioner includes: two limit rollers 5' arranged vertically, a main support guide roller 6' and a pressing roller 4'. Among them, the main support guide roller 6' and the pressing roller 4' are arranged laterally.
