Sponge Flat Belt - product range overview

What Is a Sponge Flat Belt?

A Sponge Flat Belt is a flat belt whose working face is covered with sponge, often protected by a woven cloth skin. The cloth gives a tough, high-grip surface while the sponge underneath cushions and conforms to the product. Sponge flat belts are used on conveyors, feeders and synchronised lines that must handle delicate goods quietly, gently and without leaving marks.

Because we manufacture in our own plant, we can advise on the right compound, cord and tooth profile for your machine before you order, and back it up with sample belts for your own testing.

Key Advantages of Our Sponge Flat Belt

Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.

Tough Cloth Skin

A woven cloth face resists tearing and wear while keeping a high, consistent grip.

Cushions the Product

The sponge layer beneath absorbs contact forces and conforms to uneven products.

High Grip, No Marks

The cloth face holds products securely and releases them cleanly without marking.

Quiet, Smooth Running

Sponge damping and a soft face make for one of the quietest belts on the line.

Exact Dimensions

Made to your width and length for a ready-to-fit belt.

Factory Bonded

Sponge and cloth layers are bonded in our plant for a strong, lasting join.

Sponge Flat Belt Frequently Asked Questions

Quick answers to the questions our customers ask most often about sponge flat belt.

What is a Sponge Flat Belt used for?

It feeds and conveys delicate goods such as glass, electronics, printed sheets and food that must be handled gently, quietly and without marks.

Why is a cloth skin used over the sponge?

The woven cloth gives a tough, tear-resistant and high-grip surface, protecting the softer sponge underneath and extending the belt life.

How thick can the sponge be?

We bond sponge from about 1 mm to 20 mm onto base belts from 0.8 mm, so we can match most feeding and conveying duties.

Can you supply an endless sponge flat belt?

Yes. We make endless belts for smooth running as well as open lengths with a joint kit for on-site fitting.

How long does production take?

Standard Sponge Flat Belts are typically ready in 7 to 10 working days after we confirm dimensions and materials.
