Question

What is the function of an automatic coil wrapping line?

What components make up an automatic coil wrapping line?

What types of materials and shapes are supported by the automatic wrapping line?

What is the difference between semi-automatic and fully automatic coil wrapping lines?

Can the automatic coil wrapping line be equipped with additional functions?

Accepted Answer

Automatic coil wrapping lines are designed to protect high-value metal coil products such as stainless steel wire, low-carbon steel, high-carbon steel, galvanized wire, copper strip, copper wire, aluminum strip, and iron wire from corrosion, moisture, and surface contamination during transport. These lines use materials like woven tape, PE film, and kraft paper to perform automated through-the-eye wrapping, ensuring the products remain well protected during storage and shipping.

Accepted Answer

A standard coil wrapping line consists of a wire drawing machine, coil wrapping machine, and strapping machine. The wrapping system features a C-style rotating ring wrapper, which allows for through-the-eye wrapping. Depending on the size of the wrapping film, the roll can be mounted either on the rotating ring or at the side of the wrapping station.

Accepted Answer

The line is suitable for ring-shaped products made from materials such as stainless steel, low- and high-carbon steel, galvanized wire, copper and aluminum strips, and iron wire. These products can all be wrapped using a through-the-eye method.

Accepted Answer

Semi-automatic stretch wrapping machines are typically used for lower-volume packaging. Operators need to manually deliver the coils using a forklift or pallet jack, attach the film to the coil, start the machine, and detach the film at the end of the cycle.
In contrast, fully automatic systems require minimal operator intervention. After loading the film, it handles the entire wrapping cycle automatically. Coils are usually conveyed via a powered conveyor system, and once positioned, the wrapping process begins without manual input.

Accepted Answer

Yes. Optional features include coil centering, weighing and coiling, material transfer and wrapping, real-time label printing and application, material sorting, temporary storage, data input, and unloading functions, offering enhanced flexibility and automation across the production line.
