Abstract: In a method for buffering products (P), such as bottles, cans and pots, wherein the products are carried upwards on a moving, inclined first conveying surface (7) at a first flow rate. The products on said conveying surface can accumulate against a guide member (11) at the upper end, after which the products are guided from the guide member onto a second conveying surface (8), on which they are conveyed onwards at a second flow rate. The first conveying surface (7) is disposed at an such 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, products (P) can be buffered in a simple manner, whilst the products exert only little pressure on each other.
