Abstract: A method for buffering products, such as bottles, cans and pots, wherein the products are carried upwards on a moving, inclined first conveying surface at a first flow rate. The products on the first conveying surface can accumulate against a guide member at the upper end of the first conveying surface, after which the products are guided from the guide member onto a second conveying surface, on which they are conveyed onwards at a second flow rate. The first conveying surface is disposed at such an angle and is provided with such a surface condition that the dragging force exerted on the products from the first conveying surface is just a little greater than the force of gravity being exerted on the products in the direction along the conveying surface. As a result, the products can be buffered in a simple manner, while the products exert only little pressure on each other.
