Automatic Adhesive Tape Roll Cutting Rewinding Line Manufacture

Adhesive Tape Slitting & Rewinding Machine: The Precision Converting Solution

An Adhesive Tape Slitting & Rewinding Machine is a core piece of industrial equipment designed to transform large,

economy-sized"jumbo rolls" into narrow, customer-ready rolls. It is the definitive machine for tape manufacturers and converters, bridging

the gap between raw material production and end-user application.

Core Function: The Conversion Process

The machine performs a continuous, precision process to add value and utility:

1. Unwinding: A master jumbo roll is mounted on a unwind shaft. Advanced systems feature a motorized unwind with automatic tension

   control.

2. Slitting: The wide web of tape is precisely cut into multiple narrow strips. The method used is critical and depends on the tape's properties.

3. Rewinding: The individual slit strips are neatly and tightly wound onto new cores, creating the final product rolls.

Key Technical Components & Features

• Precision Slitting Systems (The Heart of the Machine):

  • Shear Slitting: The most common and versatile method. A circular blade cuts against a counter-roller in a scissor-like action.

    Ideal for PVC, PP, double-sided, and foam tapes, providing a clean edge with minimal adhesive gumming.

  • Razor Slitting: A stationary blade presses against the tape. A cost-effective solution for light-duty papers and films, but can cause

    adhesive bleed on sticky tapes.

  • Score (Crush) Slitting: A circular blade cuts against a hardened anvil roller. Best for non-wovens and some paper tapes, but can generate

    dust.

• Advanced Tension Control:

  A closed-loop servo system is essential for producing hard, uniform rolls. It automatically maintains perfect tension, preventing wrinkles,

  telescoping, and material deformation.

• Versatile Rewinding Technology:

  • Center Surface Rewind: Combines the control of a center-driven shaft with the

    roll-hardening capability of a surface drum, ideal for delicate and sticky tapes.

  • Dual Rewind Shafts: Standard for high efficiency, allowing one set of rolls to be unloaded while the other is winding.

• Automation & Control: A Programmable Logic Controller (PLC) with a Touch-Screen HMI

  (Human-Machine Interface)

• Specialized Accessories:

  • Liner Take-Up Unit: Essential for rewinding the release liner from double-sided tapes or labels.

  • Web Guiding System: Ensures the material runs perfectly centered for consistent slit width accuracy.

  • Automatic Ejection & Log Counting: For fully automated production lines.
