China Customized Slitting Machine Manufacturers and Suppliers - Bulk Slitting Machine

Product Overview

Engineered for continuous, high-speed slitting and rewinding of continuous web materials. This industrial slitting machine is built on a heavy-duty annealed steel frame to eliminate vibration at high running speeds. It processes flexible packaging films, metal foils, technical textiles, and pressure-sensitive adhesives with precise tension control and clean, dust-free edge finishes.

Primary Function: Unwinding, longitudinal cutting (shear, razor, or crush), and dual-shaft rewinding.
Core Advantage: Closed-loop tension regulation prevents material elongation, telescoping, and edge meandering during high-speed acceleration.

Key Features

Closed-Loop Tension Control:

Real-time feedback via load cells on both unwinding and rewinding stations, automatically adjusting torque as roll diameters change.

Integrated Edge Guiding (EPC/LPC):

Ultrasonic and optical sensors track web edges or printed lines to ensure lateral alignment within +/-0.1 mm prior to slitting.

Precision Slitting Assembly:

Hardened alloy tool steel cutter shafts mounted on high-precision angular contact bearings, minimizing runout and eliminating burrs.

Automated Waste Edge Management:

Integrated trim winders or venturi suction blowers continuously evacuate edge trims to prevent wrapping on rollers.

Ergonomic Safety Interlocks:

Light curtains, emergency stop pull cords, and pneumatic safety chucks comply with CE machinery directives.

FAQ

Q: How do you prevent material telescoping on rewound rolls when running stretchy films like PE?

A: Telescoping is prevented through three combined mechanisms:
1.Taper tension programming (automatically reducing tension as the roll diameter increases).
2.Closed-loop pneumatic differential rewinding shafts that compensate for thickness variations across the web width.
3.Precision contact lay-on rollers with adjustable pneumatic pressure to exhaust trapped air between layers.

Q: What is the minimum slitting width achievable for thin aluminum foils?

A: Using specialized heavy-duty bottom driven rotary knife holders and high-precision carbide top blades, the minimum achievable slitting width is 30 mm for standard applications, with ultra-narrow configurations reaching down to 15 mm depending on material thickness and temper.

Q: Can your PLC control system integrate with our existing factory MES (Manufacturing Execution System)?

A: Yes. The Siemens-based control architecture supports standard industrial protocols including OPC UA, Modbus TCP, and Profinet, allowing seamless data export for production telemetry and traceability.
