Zusammenfassung:	The device (32) has rotatable lower feedrolls (34, 35) mounted on a pick up housing (38) and set in rotation in harvesting mode by a cutting-length gear. Rotatable upper feedrolls (36, 37) are arranged to be movable relative to the lower feedrolls. An external force-activated adjustment drive changes the position of one of the upper feedrolls (36, 37) relative to one of the lower feedrolls. A spring such as tension spring is arranged between the adjustment drive and the upper feedrolls. Ends of the spring are connected to one of the feedrolls and to an oscillating and/or movable holder.
