摘要

The driveshaft (1) driving at least one rotary roller (2) is characterized in that the external part (6) of said driveshaft (1) presents surfaces (7, 7') which have been treated by projecting particles in order to provide the shaft with controlled roughness appropriate for providing slip-free driving of the roller (2) with respect to the shaft (1).
