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 formedbetween the guide pan and the bale-forming belts.
