NRC Automatic Adhesive Tape Making Machine

An adhesive tape making machine is a complex industrial production line designed to coat a flexible backing material with a layer of adhesive and then convert it into finished rolls. The process is continuous, high-speed, and highly automated.

This machine is responsible for converting the large jumbo roll (or "log roll") produced by the coating machine into the final, sellable rolls of specific width and length.

What is a Slitting/Rewinding Machine?

A slitting/rewinding machine takes a wide master roll of finished adhesive tape and performs two main functions:

1. Slitting: Cutting it into multiple narrower strips of the desired width.

2. Rewinding: Winding these strips onto individual cores to create the final product rolls.

It is a separate, standalone machine that works in tandem with the main coating line.

The Slitting/Rewinding Process

1. Loading: The jumbo roll is loaded onto the unwind stand.

2. Threading: The web is threaded through the guide, slitting, and rewind sections.

3. Slitting: The operator sets the blade positions for the desired widths. The slitting method is chosen based on the tape type.

4. Rewinding: The machine starts. The tape is slit and wound onto individual cores on the rewind shafts. The tension and speed are carefully controlled.

5. Length Measurement: An encoder measures the length of tape being wound.

6. Ejection & Packaging: When the preset length is reached, the machine stops, the rolls are ejected, and the process repeats.
