In the first step, the moving roller 32 is adopted to move the first strip material 9 downward, because as the radius of the roll decreases as the roll decreases, the angle between the roll and the first strip material 9 passing through the fixed roller 31 and the horizontal plane changes, which is unfavorable for the first strip material 9 to be inserted into the material through-hole 513 due to the fact that the material through-hole 513 corresponds to the first strip material 9, the fixed roller 31 is adopted to move downward to abut against the first strip material 9, so that the angle between the first strip material 9 passing through the fixed roller 31 and the moving roller 32 and the horizontal plane is a certain value, and the first strip material 9 in the second step is convenient to be inserted into the material through-hole 513.

In step six, the over roller 32 is restored to its original position so that it does not affect the swinging of the head body 51 to the second roll placement position.

The foregoing description is only of embodiments of the present invention, and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
