Sponge Covered Belts
Sponge Covered Belts: Sponge covered belts with a cloth-faced sponge surface for high friction, low noise and long wear.
Sponge Covered Belts are belts with a sponge layer covered by a protective cloth skin. The cloth face gives a consistent, low-friction yet high-grip surface that resists tearing and wear, while the sponge underneath cushions the load. This construction is widely used on conveyors, feeders and synchronised lines that handle small or delicate items and need a durable, clean and quiet running surface. GOODLY manufactures sponge covered belts in blue, green and black cloth with a choice of PU, rubber or silicone base belts.

Why add a cloth skin over the sponge?
The cloth protects the sponge from tearing and wear, provides a more consistent grip, and helps the belt run more quietly and last longer.
