A transport element (1) for transporting flat goods includes an inner support member (2) that can be connected to an axle or shaft, and an outer ring member (14) of a rubber-elastic material that at least partially encloses and is connected in a formlocking manner to the support member (2). The elasticity of the rubber-elastic material is greater than the elasticity of the material of the support member (2). The ring member (4) comprises an outer contact surface (5) for the frictionally gripping transport of the flat goods. The transport element (1) is embodied in such a manner that it exhibits only very small fluctuations in the radially measured effective spring constant thereof as evaluated along the contact surface (5) around the circumference direction of the ring member (4). In order to achieve this, the support member (2) has a plurality of grooves (7) that are arranged distributed in an outer circumferential surface (6) and that are open at least toward the outer circumferential surface (6). The grooves (7) are undercut in relation to the respective radial direction. Each groove (7) has an opening width (16) that extends over an angular range a of at most 5.degree..
