1. Coil storing saddle: Put coil ready on the saddle, coil car (trolley) can come under the coil and lift it up, which reduces overhead crane working time and avoid steel coil being damaged if crane directly put coil on coil car.

2. Coil loading car: Either floor type coil car or pit type, ensure efficient coil loading onto uncoil mandrel.

3. Single mandrel uncoiler: Hydraulic expansion mandrel proper for 508mm, and can install additional segments or rubber sleeve to uncoil bigger ID coils. The load on mandrel varies with different dimensions metal coils.

4. Coil head traction press arm, peeler shoveling plate: Cooperate with each other to open coill head and send into pinch feeder.

5. Pinch feeder and preleveling equipment: In threading send coil head forward to slitter, in automatic mode, synchronous with slitter continuously sending strip into accumulator loop.

Here are some key features of a high-speed thin sheet slitting line:

1. Speed: These steel sheet slitting line machines are built for high-speed operation, allowing for rapid processing of thin sheets. They can achieve high production rates, which is essential for industries that require large volumes of slit strips.

2. Precision: The slitting line is equipped with advanced controls and precision components to ensure accurate slitting. It can handle thin sheets with precise tolerances, resulting in consistent strip widths and straight edges.

3. Automatic setup: Modern slitting lines feature automated setup capabilities, reducing the time required for changeovers between different sheet sizes or materials. This feature enhances productivity and reduces downtime.

4. Coil handling: The slitting line can handle large coils of metal, unwinding them and feeding them into the machine for processing. Coil loading and unloading mechanisms are designed to operate smoothly and efficiently.

5. Slitting knives: The line is equipped with multiple circular slitting knives, which can be adjusted to achieve the desired strip width. These knives are made from high-quality materials and are precision-ground to ensure clean and precise cuts.

6. Recoiling and rewinding: After slitting, the line can rewind the slit strips onto separate recoiling mandrels or wind them into individual coils. This feature allows for easy handling, transportation, and storage of the slit strips.

7. Quality control: High-speed thin sheet slitting lines often incorporate quality control systems to detect any defects or inconsistencies in the material. These systems can include sensors, cameras, and automated inspection mechanisms to ensure the output meets the required specifications.

8. Safety features: Safety is a crucial aspect of any industrial machine, and slitting lines are no exception. These steel sheet slitting line machines are equipped with safety measures such as emergency stop buttons, safety guards, and interlocks to protect operators and prevent accidents.
