[0026] Specifically, the feeding section 10 includes a coil plate 1 for carrying several welding strip rolls 8, and a main take-up roller 2 and a longitudinal sag assembly 3 arranged sequentially between the coil plate 1 and the stretching section 20.

The horizontal moving module 61 is preferably a linear motor, and the vertical moving module 63 is preferably a cylinder.

[0037] In use, the horizontal moving module 61 and the vertical moving module 63 drive the puller 5 to move horizontally and vertically. During the alternating pulling of the welding strip, both pullers 50 move forward, upward, backward, and downward, and the two pullers 5 are staggered in height to avoid interference between them. Using these two pullers 50 can improve pulling efficiency, reduce energy consumption, and lower production costs.
