SHFB-PT Waste Edge Rewinding Machine | Automatic Paper, Film & Nonwoven Trim Edge Collector

The SHFB-PT automatic waste edge rewinding machine is a matching auxiliary unit for slitting and rewinding production lines. It automatically collects paper edges, plastic film edges, nonwoven trims, and textile fabric waste generated during the converting process — replacing 1-2 manual workers and keeping the workshop clean, tidy, and free from waste material entanglement.

Core Functions and Working Principle

Designed specifically for production lines in printing, packaging, film, non-woven fabric, and textile industries, the SHFB-PT automatically reels in various waste edge materials generated during the slitting and rewinding process. The machine eliminates manual material collection, significantly improving workshop production efficiency.

Automatic Waste Edge Collection

The machine continuously winds waste edge material — paper, film, nonwoven, or textile — onto a paper tube as it is generated by the upstream slitter. With applicable paper tube widths of 100-500mm and waste edge widths of 5-40mm, it handles the full range of trim widths produced by standard converting equipment.

Labor Cost Reduction

A single SHFB-PT unit replaces the labor of 1-2 workers who would otherwise manually collect and dispose of waste edges. This frees operators to focus on machine monitoring and quality control, while eliminating the safety hazards and inefficiencies of manual waste handling.

Workshop Cleanliness and Safety

By automatically winding waste edges into neat rolls (maximum winding diameter 400mm), the machine prevents the waste material entanglement and messy accumulation that plague manual collection workflows. This keeps walkways clear, reduces fire risk from loose film edges, and maintains a professional production environment.

Seamless Production Line Integration

The SHFB-PT is engineered as a matching unit for Sanhui slitting and rewinding machines. Its compact footprint (1200x750x630mm) and lightweight construction (~180kg) allow easy placement alongside any slitter-rewinder without requiring major line reconfiguration.

Key Components and Build Quality

1.5KW Asynchronous Motor with Kewo Inverter

The machine is powered by a domestically produced 1.5KW asynchronous motor paired with a 1.5KW Kewo inverter for precise speed control. This drive combination delivers stable winding performance across different waste material types and thicknesses, from lightweight film edges to heavier paper trims.

Autonics Precision Control Valve

The tension and positioning system features an Autonics (South Korea) precision control valve, ensuring consistent winding tension that prevents loose rolls, telescoping, and material slippage during high-speed collection.

Pull Rod Positioner and Wire Conveyor

High-quality domestic pull rod positioner and wire conveyor components guide waste edge material smoothly from the slitter output to the winding station. The cylinder assembly is also a high-quality domestic model, selected for reliability and easy maintenance.

Designed specifically for production lines in printing, packaging, film, non-woven fabric, and textile industries, this machine can automatically reel in various waste materials such as paper edges, film edges, and fabric edges generated during the production process, completely replacing manual material collection. A single unit can save the labor costs of 1-2 people, significantly improving workshop production efficiency and freeing production lines from the pain points of waste material entanglement and messy accumulation.

Application Industries and Materials

Printing and Packaging Industry

Paper edge waste from printing and packaging production lines is automatically collected, preventing paper trim accumulation that can jam equipment and create dust hazards. The SHFB-PT handles paper edge widths from 5mm to 40mm with paper tube widths up to 500mm.

Plastic Film Converting

Plastic film edges from slitting and rewinding lines — including BOPP, PET, PE, and PVC film trims — are wound into compact rolls, eliminating the loose film edge tangles that are a common safety and efficiency problem in film converting facilities.

Nonwoven Fabric Production

Nonwoven fabric trims from converting lines are collected automatically, preventing the lightweight fiber waste from dispersing throughout the workshop and contaminating finished products.

Textile Industry

Textile fabric edges and trims from slitting operations are wound into manageable rolls, reducing material waste handling labor and keeping textile production lines running at peak efficiency.

Frequently Asked Questions

What waste edge materials can the SHFB-PT collect?

The machine collects paper edges, plastic film edges, nonwoven fabric trims, and textile fabric waste generated during slitting and rewinding operations. It handles waste edge widths from 5mm to 40mm, covering the full range of trim widths produced by standard converting equipment.

How many workers can the SHFB-PT waste edge machine replace?

A single SHFB-PT unit replaces the labor of 1-2 workers who would otherwise manually collect and dispose of waste edges. This allows operators to focus on machine monitoring and quality control while eliminating the inefficiencies and safety hazards of manual waste handling.

What is the maximum winding diameter of the waste edge collector?

The maximum winding diameter is 400mm, allowing the machine to collect a substantial volume of waste edge material before a roll change is needed. This minimizes operator intervention during continuous production runs.

What paper tube widths are compatible with the SHFB-PT?

The machine accepts paper tubes with widths from 100mm to 500mm, accommodating a wide range of slitting line configurations and waste edge collection requirements.

Can the SHFB-PT be integrated with existing slitting and rewinding lines?

Yes, the SHFB-PT is designed as a matching auxiliary unit for Sanhui slitting and rewinding machines. Its compact footprint (1200x750x630mm) and lightweight construction (~180kg) also allow integration with most standard converting equipment from other manufacturers.

What are the core components and their brands?

The machine uses a 1.5KW domestic asynchronous motor, 1.5KW Kewo inverter, Autonics (South Korea) precision control valve, high-quality domestic pull rod positioner, wire conveyor, and cylinder. All components are selected for reliability and easy maintenance.
