Abstract: A drive roller (1) comprising a central hub (4), a body (5) extending around the central hub, the body (5) being made of a deformable material, a deformable band (8) extending over a circumference of the drive roller, and first rigid fins (17) and second rigid fins (18) arranged in alternation and extending radially inside the body (5). Each first fin presents a proximal end (17a) fastened to the central hub, and each second fin presents a distal end (18b) that extends in the proximity of the deformable band.
