About the GW-291A Folding Machine

The GW-291A is designed to streamline the edge finishing process for a wide range of materials, including PVC, PU, genuine leather, artificial leather, and fabric. It is an essential machine for manufacturing shoes, luggage boxes, and mobile phone cases.

To ensure maximum precision, the machine adopts an intelligent computer chip control system. It features a touch-sensitive digital display panel for easy monitoring and adjustment of melt glue temperature, glue flow, and rubber heater temperature. The machine runs on a servo electronic motor for accurate positioning and energy savings, while the electromagnetic drive system ensures smooth folding even on tight outer bends.

Key Features

Smart Computer Control

Adopts a computer chip system to make the entire operation process intelligently controlled, ensuring consistency and reducing human error.

Touch Screen Digital Panel

Equipped with a touch display control panel. Melt glue temperature, glue flow rate, and rubber temperature can be adjusted infinitesimally for perfect results.

Electromagnetic Drive for Bends

While external bend folding, the electromagnetic drive controls the slow speed automatically, ensuring the outer curve is folded smoothly without breaking or wrinkling.

Auto Cutting & Suction

Conducts automatic cutting for inner bend folding. The glue system features double protection for automatic glue suction, preventing glue from hanging or dripping.

Energy Saving & Versatility

Equipped with a servo electronic motor that saves 40% energy. By replacing components, it can also perform French piping and insole folding.

Adjustable Folding Width

The folding width can be adjusted smoothly within the range of 3mm to 6.5mm, accommodating various design requirements for different leather products.

Applications & Specifications

Perfect for high-precision folding in footwear, bags, and phone case manufacturing.

Frequently Asked Questions

How does the electromagnetic drive help with outer bends?

When folding an outer curve, the material needs more slack to avoid wrinkling. The electromagnetic drive automatically slows down the folding speed at these specific points, ensuring the material is fed smoothly and perfectly shaped.

What does "automatic glue suction" do?

The glue system is equipped with double protection. When the machine stops, it automatically sucks the glue back into the nozzle. This prevents glue from dripping onto your product, keeping the work area clean and ensuring high-quality edges.

Can I use this machine for different types of leather?

Yes, it is highly versatile and works perfectly with PVC, PU, genuine leather, artificial leather, and various fabrics.

Can it do insole folding?

Yes. The GW-291A is designed for multi-purpose use. By simply replacing specific components (molds), it can be used for French piping (piping edge) as well as insole folding.
