Gravity chute

A sorting conveyor, comprising:

• a delivery station;
• and
• a gravity chute for articles arranged on the delivery station, the gravity chute comprising a chute floor defining a conveying surface, wherein the conveying surface has a conveying angle of inclination pointing in a conveying direction, and comprising at least one side wall which laterally delimits the chute floor, wherein, in addition to the conveying angle of inclination, the conveying surface has a transverse angle of inclination directed transversely to the conveying direction and pointing to a side wall, characterised in that the side wall, to which the conveying surface runs at a transverse inclination, has first friction properties within a first region extending from the conveying surface to a height, and has second friction properties within a second region extending above the height, which differ from the first friction properties, the side wall being recessed within the first region with respect to the second region.
