• wherein a suction unit can be connected on a first side of the base body which is remote from the suction surface in order to form a suction flow,
• wherein the base body further includes a bottom wall, a top wall, and first and second side walls,
• wherein the base body is divided into suction chambers by at least first and second partition walls so as to form at least one central suction channel and at least two lateral suction channels,
• wherein spacing between partition walls at the first side of the base body is greater for the at least two lateral suction channels than for the at least one central channel, and
• wherein the at least first and second partition walls extend from, and contact, both the suction surface and the first side of the base body.
