Edge Trimmer Rewinder

In a slitting line, the waste edge rewinding machine plays a critical role by handling the scrap edges generated during the slitting process, ensuring efficient, clean, and continuous production. Its specific functions are as follows:

1. Scrap Collection & Organization

Function: Automatically winds the waste edges (e.g., burrs or width-excess portions) after slitting, preventing scrap accumulation or scattering.
Advantage: Reduces manual cleaning frequency, maintains workshop cleanliness, and complies with 5S management standards.

2. Ensuring Continuous Production

Function: By consistently winding scrap edges, it prevents material entanglement or jamming in rollers, avoiding unplanned downtime.
Advantage: Improves slitting line stability and minimizes production interruptions.

3. Improving Material Yield

Function: Neatly collected scrap edges can be recycled (e.g., remelting metal scraps or pelletizing plastic trimmings).
Advantage: Reduces raw material waste and lowers production costs.

4. Supporting Slitting Process

Function: Synchronizes with the slitter, dynamically adjusting tension to ensure scrap edges and main coils are slit uniformly.
Advantage: Prevents scrap breakage or uneven winding due to tension imbalance.

5. Safety Protection

Function: Winds sharp or high-speed scrap edges (e.g., metal strip edges), minimizing worker exposure.
Advantage: Reduces injury risks and meets occupational safety standards.

Typical Applications

Metal Processing: Collecting sharp scrap edges from slit copper/aluminum sheets or stainless steel strips.
Packaging Materials: Recycling film or paper trim waste during slitting.
Textile Industry: Handling yarn or fabric trimmings after cutting.
