专利汇可以提供Method and machine for forming a large round bale of a fibrous material专利检索，专利查询，专利分析的服务。并且The method and machine is for forming large round bales about 7 feet in diameter, 6 feet long and weighing about a ton and a half. The machine has a portable frame provided with pickup device for gathering and delivering windrowed material on to a horizontal rearwardly moving belt conveyor. Cooperating with the horizontal conveyor is an endless belt assembly movable in a generally upright circular path and including a lower extensible section that is initially movable adjacent to and in the opposite direction of the horizontal conveyor so as to form with the horizontal conveyor a baling zone. As the bale within the baling zone increases in size, the extensible section is automatically and progressively extended about the bale, in response to such increase, against a predetermined tension or pressure constantly applied on the belt assembly. A completed bale is thus compact and of a uniform density over all portions thereof. After being formed the bale can be released in the field, or carried by the machine to a desired storage location.，下面是Method and machine for forming a large round bale of a fibrous material专利的具体信息内容。
