The suction opening extends in the transverse direction (y) in the width (B) and is delimited in the working direction (x) by a front suction opening edge (4) and a rear suction opening edge (9). According to the invention, a sliding surface (5) is provided in front of the front suction opening edge (4) in the working direction (x), said sliding surface extending in the transverse direction (y) over at least 75% of the width (B) of the suction opening (3). The sliding surface (5) has,in a longitudinal section, an arc segment (6) with a radius of curvature (r) of between 40 mm and 80 mm. The sliding surface (5) has an extension length (s) of at least 15 mm in the working direction(x).
