ABSTRACT:
A drive roll drive of a wrap material feed mechanism is driven at a peripheral speed a desired percentage slower than the peripheral speed of a bale being wrapped whereby the drive rolls function also in the manner of a drag brake so that the wrap material is applied under tension to the bale being wrapped. A spreader roll is located between a supply roll of wrap material and one of the drive rolls and is so positioned relative thereto that the wrap material engages a substantial portion of the perimeter of the drive roll, such engagement diminishing the tendency of the tensioned wrap material to slip through the drive rolls. In an alternate embodiment, a wrap material monitoring device in the form of a spreader roll rotation sensing device is provided for signalling an operator both of the depletion of the supply of wrap material and of the unwanted dispensing of wrap material.
