摘要： A roll forming machine picks up crop material and forms, twine wraps and discharges rolls or large round bales thereof as the machine is continuously moving across the field. The machine has a mobile frame supporting a pickup and a floor, the latter supporting a lower conveyor. A front upper apron is supported on the frame above a front portion of the lower conveyor and floor and defines a front roll forming region therewith. A rear upper apron is supported on the frame above a rear portion of the lower conveyor and floor and defines a rear roll forming region therewith. Formation of a crop material roll is initiated in the front region and completed in the rear region after the roll has been partially formed in the front region and transferred to the rear region. Mechanism on the frame is operable to lower or raise a rear end of the front upper apron in order to correspondingly initiate formation of a roll in the front region or permit transfer of the roll to the rear region. Means is provided for controlling the operation of the mechanism so as to insure that the roll located in the front region is formed to at least a preselected minimum diameter size therein before the rear end of the front upper apron is raised and the roll is transferred from the front region to the rear region.
摘要翻译：当机器连续地移动穿过场时，辊成形机拾取作物材料并形成，缠绕和排出辊或大圆包。该机器具有支撑拾取器和地板的移动框架，后者支撑下部输送机。前上围板支撑在下输送机和地板的前部上方的框架上，并且与其定义前辊成型区域。后下围板支撑在下输送机和地板的后部的框架上方并且与其一起限定后辊成形区域。作物材料辊的形成在前部区域开始，并且在辊部分地形成在前部区域中并且被转移到后部区域之后在后部区域中完成。框架上的机构可操作地降低或升高前上围裙的后端，以便相应地启动在前区域中形成卷，或允许将卷转移到后区。提供了用于控制机构的操作的装置，以便确保位于前部区域中的辊至少形成在其中的前选择的最小直径尺寸之前，其中前上围裙的后端升高并且辊从前部区域到后部区域。
