High Speed Paper Tube Roll Converting Making Machine In Africa

High Speed Paper Tube Roll Converting Making Machine

What Does It Do?

This machine takes three main inputs:

1. Master Rolls of Flexible Material: Such as plastic film, foil, fabric, non-wovens, paper, or label stock.

2. Paper Tubes/Cores: (Which it can often make itself, or they can be pre-made).

3. Packaging Materials: Like end caps, labels, and shrink film.

Its output is finished, consumer-ready or industry-ready rolls of product, wound onto the paper tubes.

Integrated Process Flow

A high-speed converting line integrates the spiral tube machine with a high-performance slitter/rewinder. Here's the typical sequence:

Stage 1: Tube Making (The "Making Machine" Part)

• This section operates exactly like a high-speed spiral tube machine, producing paper cores on demand.

• Key Feature: It includes an automatic core feeder that precisely transfers the newly made (or pre-made) cores into the rewinding section without stopping the line.

Stage 2: Unwinding & Slitting (The "Roll Converting" Part)

• A large "master roll" (jumbo roll) of the flexible material (e.g., polyethylene film) is mounted on an unwind stand.

• The material web is fed into a slitting station, where razor blades or shear-cut blades slit the wide web into multiple, narrower strips. The number of strips determines how many finished rolls are produced simultaneously.

Stage 3: Rewinding onto Cores (The Key Converting Step)

• The slit webs are guided towards the cores.

• The cores are automatically positioned and rotated.

• The leading edge of each slit web is attached to its corresponding core (often via a tacking system or adhesive). The core spins, winding the material tightly around itself to form the final log roll.

Stage 4: Log Separation & Finishing

• Once the roll reaches a pre-set diameter (measured by a sensor), the continuous "log" of multiple rolls is cut apart by a high-speed saw.

• The individual rolls are then ejected for:

  • Quality Check: Inspection for defects.

  • Packaging: Automatic labeling, end-capping, and shrink-wrapping.

Primary Applications & Industries

These machines are essential in industries that sell products in roll form:

• Flexible Packaging: Producing rolls of plastic wrap, cling film, aluminum foil, parchment paper, and wax paper.

• Hygiene & Medical: Manufacturing rolls of toilet paper, paper towels, non-woven medical wraps, and gauze.

• Label Manufacturing: Converting large printed label stocks into individual rolls for dispensers.

• Textiles: Creating rolls of interfacing, fusible web, or other narrow fabrics.

• Adhesive Tapes: Rewinding and slitting large rolls of tape into consumer or industrial sizes.
