    • A large round baler has a wrapping material supply arrangement mounted to its discharge gate adjacent an upright run of belts used for forming a bale within the baling chamber of the baler. A pair of wrapping material feed rolls are arranged with one roll being located forwardly of and above the other. The wrapping material feed rolls are located below a chamber for holding a roll of wrapping material and disposed for having wrapping material engaged with the rolls in an S-shaped or serpentine path beginning at the rear periphery of the rear roll, then extending about a lower half of the rear roll and through a nip or gripping zone between the rolls and then about an upper half of the front roll, thus leaving the rolls at the forward side of the front roll. A guide chute extends downwardly and forwardly from the forward periphery of the front roll at a relatively steep angle, the guide chute having a lower terminal end located vertically above a guide surface of a guide pan extending beneath the discharge gate in close relationship to a fore-and-aft extending run of the bale-forming belts, whereby wrapping material exiting the guide chute will gravitate to the guide surface of the guide pan. The belts move the wrapping material along the guide pan to the baling chamber for wrapping a formed bale rotating therein. A knife is provided for cutting the wrapping material at a location adjacent a lower end of the guide chute, and a resilient stop or anvil is located in the path of a cutting edge of the knife to ensure that cutting will take place along the entire length of the cutting edge. A wrapping material sensor is located for sensing when wrapping material is present in a path extending between the guide chute and a nip formed between the guide pan and the bale-forming belts.
    • 大型圆形打捆机具有安装在其排放门上的包装材料供应装置,其邻近用于在打包机的打包室内形成捆包的直立带。 一对包装材料进给辊布置成一个辊子位于另一个的前方和上方。 包装材料进料辊位于用于保持一卷包装材料的室下方,并且设置成使包裹材料与辊接合在从后辊的后周边开始的S形或蛇形路径中,然后围绕较低的 后辊的一半,并且通过辊之间的辊隙或夹紧区域,然后围绕前辊的上半部分,从而将辊留在前辊的前侧。 引导滑槽以相对陡峭的角度从前辊的前边缘向下并向前延伸,导向滑槽具有垂直于引导盘的引导表面上方的下端,该引导表面在排放门下方紧密地关系于前部 - 捆包形成带的后延伸行程,由此离开导槽的包裹材料将被引向导向盘的引导表面。 皮带将包裹材料沿着导向盘移动到打包室,用于将形成的捆包裹在其中旋转。 提供了一种用于在邻近导槽的下端的位置处切割包装材料的刀,并且弹性止动件或砧座位于刀的切割刃的路径中,以确保沿着整个长度进行切割 的前沿。 包装材料传感器被定位成用于感测何时包裹材料存在于在导向槽和在导向盘和捆包形成带之间形成的辊隙之间延伸的路径中。
