Abstract (en)
[origin: WO2011160770A1] The transporting roller (1) has teeth (6) arranged in a distributed manner over the circumference. To allow a high advancing force to be achieved with the transporting roller (1) at the same time as an only low pressing force over a long operating time and service life, at least some of the teeth (6) comprise a main tooth (7) and at least one secondary tooth (9), which is arranged at a distance from the main tooth and has a smaller tooth tip radius (r2) than the main tooth (7). With the secondary teeth (9), there is an additional transfer of force exerted on the workpiece (2). The secondary teeth (9) limit the depth of penetration of the main teeth (7). When there is a high pressing pressure, the secondary teeth (9) penetrate partially into the workpiece (2). The main and secondary teeth (7, 9) penetrate only slightly into the workpiece (2), and so only a small amount of material has to be removed to eliminate any markings.
