Belt-over-belt conveyors

A cleat is a hard edge. On a flexible pouch landing badly, it is a tear. Gripping the product between two belts instead carries it up the incline without anything to catch on.

02The problem

Why cleats fail on pouches.

Cleated conveyors are the usual way to move product up an incline, but they do not suit everything. Flexible pouches are delicate, and if a pouch lands wrongly on a cleat the bag can rip. That means product loss and the downtime to clean the conveyor.

The same applies to unevenly shaped, softer products that a cleat can damage simply by pressing on the wrong part of them.

How the belt-over-belt works

Two flexible polyurethane belts are oriented one over the other. As product moves into position it is gripped between the twin belts, creating a pocket that carries it securely up or down. Nothing has to land on an edge, because there is no edge.

03What it gains

Three benefits over a cleated incline.

Beyond avoiding damage, holding the product rather than carrying it changes what the conveyor can do with the line.

01 · Footprint

Less floor space to elevate

Because the product is gripped, the climb can be steeper than a cleated belt would allow, so the elevation takes less floor length.

02 · Orientation

Pouch orientation maintained

Product arrives at the top the same way up and the same way round as it went in, so no re-orienting step is needed afterwards.

03 · Spacing

Pouch spacing maintained

The gaps between products are preserved through the climb, which matters when the next machine expects a known pitch.

Where it is the right choice. Belt-over-belt suits flexible pouches, soft product and unevenly shaped items that a cleat would damage or that would not sit reliably on one. For rigid product that handles a cleat without harm, a cleated belt remains the simpler option.
