Rough-top Conveyor Belts
Rough top conveyor belts have a wide application range. Suitable for conveying easily-deformable or fragile goods such as parcels, paper sacks and cardboard boxes, particularly on conveyors operating on an incline, unlike smooth conveyor belts, the rough-top belts have covers that provide maximum grip to the goods being conveyed. They will cushion the load, absorb vibrations and minimise any impacts.
The belt covers have a rough rubber print on the top cover. This is applied through a special manufacturing process using impression fabric that is similar to a mould. The back of the belt comes with or without a rubber cover – known as a fabric-back or dry-back belt.
For good tensile strength and low elongation, the carcass usually consists of two, three or four plies of synthetic polyester-nylon (EP) fabric.
Available in a selection of widths, ranging from 500mm to 1600mm, our belts are manufactured with moulded or cut edges and are usually supplied with DIN Z, DIN Y, or Grade N covers for general applications.
Special compounds including MOR are available on request.
