ABSTRACT:
A transport element (1) for transporting or conveying flat goods, such as sheet goods like paper in photocopy machines and printers, 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 surrounds and is connected in a form-locking manner to the support member (2). The rubber-elastic material has a greater elasticity than the material of the support member (2). The ring member (4) has an outer contact surface (5) for frictionally gripping and transporting the flat goods. The support member (2) has a plurality of grooves (7) distributed around an outer circumferential surface (6) thereof. The rubber-elastic material of the ring member (4) form-lockingly engages the grooves (7). The grooves (7) are open at least toward the outer circumferential surface (6) with a respective opening width (16) that spans an angle .alpha. of at most 5.degree., and are undercut radially inwardly below the openings. As a result, the transport element (1) exhibits only very small fluctuations in the radially measured effective elasticity or spring constant thereof as evaluated around the circumference of the contact surface (5).
