  • Patent number: 6513307
    Abstract: A sheathing method includes the steps of depositing a bale on a sheathing carrier. The bale is pushed onto the carrier and slides on the carrier base plate against the preceding bale using a pusher-ejector device. A pushing motion of the pusher-ejector device causes a handling equipment to simultaneously move the tractor attached to the handling in a direction opposite to the direction of the pushing motion. The movement of the tractor is caused by a cross piece arranged beneath the frame of the pusher-ejector device. The carrier has a stop integral with the two rails that define the base plate. The cross piece contacts the stop to move the carrier by a step corresponding to a length of the bale in the same direction as the tractor.

  • Patent number: 6050066
    Abstract: A bale bagging apparatus is used for inserting bales in sequence into a tube of plastic film. The apparatus has a set of panels surrounding the bale at a bagging station of the apparatus and supporting the tube in a stretched state out of contact with the bale. As the bale passes through the bagging station, the tube is pulled off the panels and shrinks onto the bale. The bale support panel is equipped with a resilient sheet on the outer surface to distribute the stretching load over the bag to eliminate areas of high stress concentration on the bag. The bales are supported as they travel through the apparatus on two parallel, linear rails to minimize the draft force on the apparatus. The tube support panels pivot on axes that lie in a common plane perpendicular to the bale path.
