Application Scope & Features
● Stable Power & Constant Tension: Driven by vector motors or servo motors and equipped with an automatic constant tension control system. The main unit adopts variable frequency speed regulation technology to maintain dynamic balance during acceleration and high-speed operation. The machine runs smoothly without vibration, ensuring stable processing of webs throughout the operation.
● Intelligent Control & High Precision: Fitted with Siemens PLC intelligent control system, integrated with automatic length counting, residual material detection & alarm, and automatic stop at preset length to realize unattended operation. The rewinding unit adopts upper and lower double-station A/B air shafts combined with chain-type automatic unloading structure, enabling fast roll change and labor-saving operation.
● Accurate Web Guiding & Wide Compatibility: Equipped with a high-sensitivity photoelectric automatic web guiding system. It effectively corrects the running path of materials with irregular edges, guarantees precise slitting, and greatly improves material utilization rate and finished product qualification rate.
● High-efficiency Slitting & Automatic Edge Waste Removal: Three slitting modes are available: circular knife, flat knife and air knife, which can be switched flexibly according to material types. Matched with a high-pressure fan for automatic edge waste removal, it removes waste instantly to keep the workshop tidy and ensure uninterrupted production.
● Flexible Feeding & Heavy Load Capacity: Two hydraulic automatic loading/unloading solutions are provided: shafted and shaftless types. They are applicable to webs of different weights and specifications, eliminating heavy manual handling. The feeding process is safe and highly efficient.
● Large Roll Diameter & High Productivity: The standard maximum unwinding diameter is 1200 mm or 1400 mm, and the rewinding diameter is 1000 mm or 1200 mm. Longer rolls can be processed per batch to reduce roll change frequency. The maximum running speed reaches 300 m/min for remarkable productivity improvement.
● Customizable Shafts for Diverse Applications: 3–6 inch key-type air shafts are optional for unwinding, while 3-inch key-type air shafts are standard for rewinding. Special sizes and specifications of air shafts can be customized to perfectly meet various roll clamping requirements.
● Full Compatibility & Customization: The machine working width can be customized as per actual production demands. The infrared paper tube positioning function is optional to achieve fast and accurate alignment of paper tubes, shorten commissioning time and improve roll change efficiency.

SHWS-ZX Heavy-Duty Horizontal Slitting Machine | Multi-Function Jumbo Roll Slitter for Paper, Foil & Film

The SHWS-ZX heavy-duty horizontal slitter is engineered for ultra-large jumbo roll processing, delivering high-precision slitting and rewinding across 30-400gsm materials. With three switchable slitting modes (circular knife, flat knife, air knife), Siemens PLC intelligent control, and a maximum speed of 300 m/min, it handles kraft paper, white cardboard, coated paper, silicone paper, aluminum/tin foil, PVC film, and nonwoven fabric with exceptional stability and productivity.

Core Features & Performance

Vector/Servo Drive with Constant Tension Control

Driven by vector motors or servo motors with automatic constant tension control system. Variable frequency speed regulation technology maintains dynamic balance during acceleration and high-speed operation, ensuring vibration-free, stable web processing throughout the entire run.

Siemens PLC Intelligent Control System

Integrated with automatic length counting, residual material detection & alarm, and automatic stop at preset length for true unattended operation. The system monitors operating status in real time, automatically alarming and stopping when material runs low or faults occur to prevent waste.

Upper-Lower A/B Dual Station Rewinding with Chain Auto-Unloading

Double-station A/B air shafts enable fast roll change without downtime. Chain-type automatic unloading structure pushes finished rolls out after shutdown, eliminating manual unloading and suiting mass continuous production.

High-Sensitivity EPC Photoelectric Web Guiding ( /-0.1mm)

Effectively corrects the running path of materials with irregular edges, guarantees precise slitting alignment, and greatly improves material utilization rate and finished product qualification rate even with challenging raw materials.

Three Switchable Slitting Modes with Auto Waste Removal

Circular knife, flat knife, and air knife modes can be flexibly switched according to material types. Matched high-pressure fan automatically removes waste edges instantly, keeping the workshop tidy and ensuring uninterrupted production.

Hydraulic Shafted/Shaftless Flexible Loading

Two hydraulic automatic loading/unloading solutions available: shafted and shaftless types. Applicable to webs of different weights and specifications, eliminating heavy manual handling for safe and efficient feeding.

Large Roll Diameter & High Productivity

Standard maximum unwinding diameter up to 1500mm, rewinding diameter up to 1000mm. Longer rolls processed per batch reduce roll change frequency. Maximum running speed of 300 m/min delivers remarkable productivity improvement for industrial-scale operations.

Customizable Shafts & Full Configuration Flexibility

3-6 inch key-type air shafts optional for unwinding; 3-inch key-type air shafts standard for rewinding. Special sizes customizable. Machine working width fully tailorable. Optional infrared paper tube positioning for fast, accurate alignment and shorter commissioning time.

Frequently Asked Questions

What materials can the SHWS-ZX horizontal slitter process?

The SHWS-ZX handles kraft paper, white cardboard, coated paper, silicone release paper, aluminum foil, tin foil, PVC film, and nonwoven fabric. It supports materials ranging from 30g/m2 to 400g/m2 in web width.

What are the three slitting modes and when to use each?

Circular knife is ideal for paper and cardboard with clean shear cutting. Flat knife suits aluminum/tin foil and delicate materials requiring gentle scoring. Air knife is used for thin films and nonwoven fabrics where contact pressure must be minimized. All three modes can be switched flexibly without major reconfiguration.

What is the maximum slitting speed?

The maximum running speed is 300 m/min, achieved through vector/servo drive with constant tension control to maintain precision and stability even at high speeds.

What unwinding and rewinding diameters are supported?

The standard maximum unwinding diameter is 1500mm and the maximum rewinding diameter is 1000mm. Larger diameters can be customized upon request to accommodate specialized jumbo roll requirements.

What working widths are available?

Four standard models are available: 1100mm, 1300mm, 1600mm, and 1800mm web width. Custom working widths can also be manufactured according to specific production demands.

How does the automatic unloading system work?

The upper and lower double-station A/B air shafts are combined with a chain-type automatic unloading structure. After shutdown, finished rolls are automatically pushed onto the unloading arm, enabling fast roll change without manual handling.
