There is disclosed a low friction buffer device (10) for accumulating packages
comprising at least a resilient endless belt (16) for dragging the articles extending
over a substantially horizontal length, said at least one belt passing around at
least one motorized roller means (22). In the device according to the invention,
support members (18) extending longitudinally are provided which stand at a first
height above a reference plane (12) and on which the packages are slidably set.
The belt, when not loaded with the articles to be carried, is at a second height
above said reference plane, which is greater than the first height.
The belt is bent under the weight of the articles
such that the latter are also in contact with the support.
The friction between articles and belt is higher than the friction
between articles and support in order that the articles can be
transported by movement of the belt.
