Abstract
Abstract A conditioning machine for agricultural straw or blade material embodying a conveying drum equipped with conveying tools or implements. The conveying drum in conjunction with a guide wall forms a conveying channel which is provided with means for exerting a conditioning action upon the conveyed straw or blade material. According to important aspects of the invention the spacing between the ends of the conditioning means situated closest to the jacket or outer surface of the conveying drum and the circular path of travel of the ends of the conveying tools is smaller than the smallest inner height of the conveying channel between the jacket of the conveying drum and the guide wall measured from the axis of rotation of the conveying drum.
