<p>An arrangement (10) for positioning the longitudinal axis of an onion-shaped product, comprising a first pair of rollers (20) and a second pair of rollers (21) in which arrangement each roller has at least a truncated-cone surface and in each pair the rollers (20, 21) are placed on an axis with the truncated- cone surfaces facing each other and the two pairs of rollers are placed one after the other in a direction perpendicular to their axis, and the rollers (20, 21) of each assembly of four rollers which each time can carry an onion-shaped product can be driven in the same direction, and also that in each assembly of four rollers the conical surface of each roller of a first pair (20) of rollers has a higher coefficient of friction than the conical surface of each roller of a second pair (21) of rollers.</p> |
