Main Features

Maximum Cutting Thickness: 15 mm

The machine is designed to cut cores with a maximum wall thickness of 15 mm on one side.
The actual cutting performance may depend on the core material, density, wall structure, diameter, and condition of the cutting blade.

2000 mm Core Cutting Area

The machine provides a 2000 mm working width, allowing long cores to be positioned and processed conveniently.
The long working area makes the machine suitable for a wide range of core lengths commonly used in plastic film, packaging, paper, foil, textile, and converting industries.

Polyamide Core Support Ring

A specially manufactured polyamide support ring is installed on the metal shaft.
The core is positioned on this polyamide ring during operation. The ring helps:

• • Keep the core straight during rotation
• • Guide the core toward the cutting area
• • Provide stable support for the core
• • Reduce unnecessary metal-to-core contact
• • Improve positioning during manual cutting

The polyamide material provides a durable and low-friction supporting surface suitable for repetitive industrial operation.

Movable Aluminium Core Guide

The machine is equipped with a movable aluminium guide for supporting and positioning the core.
The operator can manually move the guide in order to push and position the core toward the cutting knife.
The combination of the polyamide support ring and aluminium guide helps maintain proper core alignment throughout the cutting process.

Belt and Pulley Driven Core Rotation

Core rotation is provided by a three-phase AC electric motor.
The rotational movement of the motor is transferred to the core through a belt and pulley transmission system. This system provides continuous and stable rotation of the core during the cutting operation.
Rotating the core while applying the cutting knife allows the blade to progressively cut through the core wall around its circumference rather than attempting to cut the entire core section at once.

Manual Core Cutting Operation

The cutting process is performed manually by the operator.
After the core is correctly positioned on the support system, the motor rotates the core through the belt and pulley mechanism. The operator then manually applies the cutting knife to the rotating core.
This straightforward operating principle provides good control over the cutting process and makes the machine particularly suitable for workshops and production facilities where different core lengths may need to be prepared according to production requirements.

Gas Spring Assisted Knife Return

The cutting mechanism incorporates a gas spring system.
After the cutting operation is completed, the gas spring assists in returning the knife mechanism to its original position. This improves operator convenience and prepares the cutting mechanism for the next cutting cycle.

Operating Principle

The core cutting process can be summarized as follows:

1. The core is placed onto the polyamide support ring and aluminium guiding system.
2. The movable aluminium guide is adjusted according to the position and length of the core.
3. The three-phase AC motor rotates the core through the belt and pulley transmission system.
4. The operator manually positions the core according to the required cutting length.
5. The cutting knife is manually applied to the rotating core.
6. The rotating movement allows the knife to progressively cut through the core wall.
7. After the cut is completed, the gas spring assists the knife mechanism in returning to its initial position.
8. The core can then be repositioned for the next cut.
