The strip-shaped material 6 passes through the feeding wheel 2, the second sub-wheel 31 and the first sub-wheel 30 in sequence and enters the winding wheel 1 in the clockwise direction.

Push and pull zero meter wheel 4, make zero meter wheel 4 direction of rotation be one-way anticlockwise, banded material 6 anticlockwise winding is on zero meter wheel 4, the winding 2 ~ 3 circles.

And starting the equipment, wherein the winding pinch roller 9 is pressed on the winding wheel 1 and is driven by friction force. Preventing the band-shaped material 6 from slipping on the winding wheel 1.

The zero meter wheel 4 is pressed on the winding wheel 1 and is driven by friction force.

the first situation is as follows: regardless of whether the speed of the backward movement of the zero meter wheel 4 is greater than the specified linear speed and the strength of the strip-shaped material 6, if it is known in advance that the strip-shaped material 6 cannot be torn off, that is, the strip-shaped material 6 is in a tight state, the first air blowing structure 51 above the zero meter wheel 4 starts to blow air, the cutter structure 50 above the zero meter wheel 4 cuts off the strip-shaped material 6 rapidly, and the broken strip-shaped material 6 moves towards the second air blowing structure 52 below the zero meter wheel 4 under the action of the air flow of the first air blowing structure 51.

Case two: depending on the speed of the backing of the zero meter wheel 4 and the strength of the strip-shaped material 6, if it is known in advance that the strip-shaped material 6 will be torn apart, the first air-blowing structure 51 starts to blow air before or while the zero meter wheel 4 is backing, and continues until the whole work is finished.

And then the second air blowing structure 52 starts to blow air, the angle of the nearby strip-shaped material 6 is corrected, the strip-shaped material is wound into the included angle between the winding wheel 1 and the input paper tape, and the transfer of the strip-shaped material 6 from the zero meter wheel 4 to the winding wheel 1 is completed. The second air-blowing structure 52 has a delay of about 0.5 seconds in air-blowing time compared to the first air-blowing structure 51.

After the whole set of work is finished, the cutting and blowing mechanism 5 and the zero meter wheel 4 retreat away from the winding wheel 1, and the retreat distance is larger than the final finished product roll diameter.
