Slitting Rewinder

High-Performance Slitting Rewinder Machine | Industrial Roll Converting Solutions with ±0.10mm Precision

Advanced Slitting Rewinders from Shanghai Honghua Digital Equipment Co., Ltd. are designed for high-volume roll conversion. We have 20 years of manufacturing expertise and 13 technology patents. Our machines can slit at 200m/min with an accuracy of ±0.10mm. Each product is equipped with PLC touchscreen control, photoelectric web alignment and automated counting for flexible packaging, label fabrication and industrial film processing. Our industrial grade units last 20 years and are 800 KG. We have many manufacturing facilities in China and warehouses in South East Asia to ensure rapid worldwide shipping.

What Makes Our Slitting Rewinder Essential for Your Production Line?

Modern roll conversion demands precision which ordinary technology today does not provide. The technique minimises uneven tension and edge defects and reduces large-diameter master rolls for manufacture.

The machine is equipped with photo-electric automatic deviation correction for high speed web alignment. This avoids wastage of resources and ensures quality batch to batch.

Output may be increased by programd pauses for automatic meter and piece counting. These features help to reduce operator effort and errors during long production runs.

The size of the system, 1100×1300×1100mm, facilitates easy incorporation into existing workplace layouts. Multi-voltage (220V/380V ±10%) versions to suit diverse facilities across the globe.

Technical Specifications & Performance Parameters

These specifications reflect rigorous quality control standards. Every roller undergoes dynamic balancing tests to prevent vibration at operating speeds. Blade geometry inspections ensure zero heat-deformation on sensitive materials.

Advanced Control Technology for Reliable Operation

Our PLC touchscreen interface gives your operators straightforward control. Simplifies difficult changes without compromising professional performance.

The unwinding system has photoelectric sensors for automated correction of web deviation. The real time adjustment avoids the misalignment problems that might lead to production downtime in standard machines.

Automatic stop features come into play at certain lengths, safeguarding materials from overwinding. This is very useful for processing pricey speciality films or coated sheets.

Our Slitting Rewinders control design provides tension monitoring throughout the full web route. The constant tension avoids crushing of the core in the inner layers and loose winding in the outer diameters.

Industrial Applications Across Multiple Sectors

Production of flexible packaging: BOPP, PET and PE films for food packaging applications. Exact slitting guarantees clean edges and no chance of contamination in the subsequent filling procedures.

Label Converting: Controlled blade depth for adhesive coated materials. Your production provides kiss-cutting precision that leaves liners intact and produces excellent die cut labels.

Paper and Non-Woven Processing: Convert wide format materials to regular roll widths for printing and laminating activities. Shear slitting ensures clean edges, without the creation of dust.

Industrial Film Making: Technical films slit for use in electronics, construction and medical. The ±0.10mm tolerance satisfies the stringent dimensional requirements of automated assembly operations.

Quality Assurance Through Comprehensive Manufacturing Controls

All Slitting Rewinders will be inspected at many stages before shipping. One component of our quality methodology is the tension linearity test throughout the whole thickness of the material.

The dynamic balancing processes are used to guarantee all spinning components fulfil G2.5 level requirements. This accuracy eliminates vibration tagging of delicate surfaces at high speeds.

Final approval includes test runs with difficult material. We look for any blocking or interleaving faults that might affect the quality of the end roll.

Your equipment is supplied with full paperwork confirming the compliance of the CE certification and quality requirements of ISO 9001. These certificates are a reflection of our worldwide manufacturing.

Customization Options for Specialized Requirements

We provide both OEM and ODM services to fit your particular conversion requirements. The hardware configurations are adapted to the specific features of the material or to the manufacturing process.

Custom voltage parameters to match local power standards. Software changes provide customised counting techniques or interaction with current industrial automation systems.

Non-standard equipment is developed for non-standard lengths of material or winding needs. Our technical team partners with you to design solutions for specific operating characteristics.

We provide flexible MOQ rules that allow for single unit testing prior to placing big production orders. This technique mitigates the investment risk for the evaluation of novel conversion processes.

Comprehensive Support Throughout Equipment Lifecycle

You have 12 months guarantee to protect your purchase and we provide life time technical support. Our support staff may give remote diagnostics and on-site help as needed.

Spare parts are stocked at regional warehouses to guarantee quick availability of components. Critical wear products are sent within 24 hours to help reduce any possible downtime.

Installation instructions allow your maintenance team to know the correct processes for installation. We give complete calibration instructions to ensure ±0.10mm slitting accuracy throughout the device life duration.

We propose a monthly calibration of the sensors to keep the web-guide accurate. Simple actuator limit switch tests retain system tracking performance during years of continuous operation.

Logistics and Global Delivery Capabilities

Professional export packing safeguards your equipment in international transportation. Multi-layer foam protection in hardwood casings assures no breakage of precise components.

We support FOB Shanghai/Ningbo, CIF and DAP terms of trade. We offer accurate logistics quotes and customs paperwork but customers may use their own preferred freight forwarders.

Options of sea freight, air freight and rail transportation are available to meet the delivery dates. Expedited delivery meets the need for urgent equipment for time-critical production launch.

Domestic customs clearance usually takes 1-3 business days. Our professional export staff is available to help you with destination country paperwork needs throughout the import process.

FAQ

Q: How does the machine maintain accuracy with variable material thickness?

A: Differential friction shafts for separate rewind rollers provide automated compensation for gauge fluctuation. This gives a uniform winding tension throughout the whole width of the roll.

Q: What is the optimum slitting procedure for abrasive materials?

A: Shear slitting with tungsten carbide blades gives the longest tool life and the cleanest cuts on paper-based or abrasive surfaces without frequent blade replacements.

Q: Can your system process stretchy films like PE?

A: Yeah. A closed loop low tension control system and specially coated rollers prevent material stretching and sticking during the unwinding and rewinding processes.

Q: How do you avoid roll telescoping on final goods?

A: The PLC provides a tension-taper curve that lessens the winding force progressively as the roll diameter grows. This stops outer layers from squeezing inside wraps.

Q: What does the maintenance of the web-guide system require?

A: Monthly sensor calibration and actuator limit switch verification provides for ±0.10mm tracking accuracy throughout the operating lifespan of the equipment.
