Working Principle of Vertical Gantry Slitting Machine

High rigidity, extra-wide working width, high precision, strong load capacity and long service life.

● High structural rigidity: Integrated gantry frame features excellent load-bearing and anti-deformation performance, running stably without vibration.

● Extra-wide processing width: Capable of handling super-wide rolls, greatly improving production efficiency.

● Consistent slitting accuracy: Deformation-resistant frame ensures precise cutting with neat edges even at high speed.

● Super load capacity: Suitable for heavy and large-diameter master rolls for mass production.

● Versatile material compatibility: Works with soft film, thick paperboard, rigid aluminum foil and various composite materials.

● Durable construction: Robust design withstands long-term heavy-duty operation with low failure rate.

Frequently Asked Questions
Find answers to common questions about our machines and services
What products do we manufacture?

We mainly produce slitting machines, inspection machines, and cross-cutting machines in various models and specifications.

What materials are applicable for slitting machines?

Slitting machines are suitable for slitting and rewinding of various coiled materials, including plastic films (PET, OPP, PE, PVC, laminated film, aluminized film), assorted roll papers (kraft paper, masking paper, adhesive sticker paper, coated paper, glossy paper, wrapping paper, etc.) and other various rolled substrates.

What is the maximum speed of your slitting machines? What about the actual production speed?

Our high-speed slitting machine can reach a maximum running speed of 800m/min, and standard models can reach 200m/min and 400m/min. The actual production speed will be adjusted according to material thickness, width and slitting accuracy requirements. Generally, the stable running speed is 70%-80% of the rated speed. For example, 0.05mm thick PET film can run stably at 350m/min when the slitting width is above 50mm.

What are the maximum unwinding and rewinding diameters? What is the load capacity?

The vertical standard models feature winding diameters of 600 mm and 800 mm, with unwinding diameters of 800 mm and 1000 mm; the horizontal standard models have winding diameters of 600 mm, 800 mm, and 1200 mm, with unwinding diameters ranging from 1200 to 1600 mm. Different models support unwinding loads up to 1500 kg or even over 3000 kg. Customized solutions for specific dimensions and load requirements are available upon request.

Can the slitting width be customized? How many strips can be slit simultaneously?

Yes, slitting width can be customized, with the minimum slitting width down to 10mm. The number of simultaneously slit strips depends on the total material width and minimum slitting width. For example, a 1600mm wide machine can slit up to 32 strips of 50mm wide products.

What optional functions do you have? Which ones are more practical?

Practical optional features include: 6-inch rewinding shaft (suitable for large-diameter rewinding), Automatic paper feeding tube (enhances production efficiency and accuracy); automatic blade leveling/milling mechanism (reduces manual adjustment time); automated packaging function (simplifies packaging process); automatic waste edge winding device, etc.

What should I do if the equipment breaks down? How fast is your after-sales response?

We provide 7×24 hours technical support, and general faults can be solved through remote guidance. For home visits, we will arrange them within 48 hours.
