Abstract

In a loading apparatus, sacks are moved from a supply source along a conveyor to a device which arranges the sacks into a layer. From this device, the layer of sacks is moved over a double conveyor belt structure to a member which loads the layer directly onto a loading surface or onto a previously deposited layer of sacks on the loading surface. To provide continuous operation of the apparatus even when a loading surface is being replaced, the different parts of the apparatus can operate at variable speeds. The double conveyor belt structure which normally moves continuously supplying layers to the loading member, switches to a step-wise movement and stores a number of layers of sacks until the loading surface is replaced and ready to be loaded.
