10:50am The orange crates travel on conveyor belts over the heads of the sorters and packers below. As crates arrive they are unpacked and at this stage individual orders are made up and placed in smaller green crates with the other items that make up that order.
10:55am Packers then take the green crates and package the contents ready for despatch, putting CDs, DVDs, books and everything else from electrical goods to kitchenware into the distinctive Amazon cardboard packaging.
At this stage the orders are identified by bar codes generated when the order is processed. The next stage will see those bar codes matched against delivery addresses on the database in order for labels to be printed up.
11:00am The barcode is scanned and the address label printed and stamped onto the package as it travels along a conveyor belt. At this stage the package is also weighed. If it is lighter or heavier than the item or items on the order, the system automatically queries the contents and the parcel is rejected.
The system is so sensitive it will be able to tell the difference between a parcel which contains four CDs when it should contain five or the difference between a hardback and a paperback version of the same book.
The fast-moving conveyor belts then whip the packages away for posting out to all corners of the UK.
