  • Patent number: 6848238
    Abstract: The invention relates to a procedure for wrapping a straw fodder bale with plastic. In the wrapping operation, to wrap the corner between the envelope surface and the end surface of the bale, the axis of rotation of the plastic roll is turned from an upright position into a substantially horizontal position and the bale is rotated so that the plastic film being stretched on the bale from the plastic roll (16) is caused to bend over the corner of the bale partly onto the envelope surface and partly onto the end surface of the bale.
