  • Patent number: 4972656
    Abstract: A round bale wrapper for packing feed, like green forage and straw, intended for ensilage of the feed and conservation of the straw. The round bale is made to turn both about a substantially horizontal and a substantially vertical axis. The round bale wrapper comprises a round bale table, a chassis with round bale table being tiltable relative to the latter, and a packing sheet dispensing means which is externally provided relative to round bale table. For continuous automatic packing of round bales the round bale wrapper comprises means for clamping and cutting sheet which is located between the round bale, and the sheet dispensing means. At a predetermined point of time or tilting angle during the tilting movement of round bale table clamping and cutting means operate sequentially. Upon cutting of the sheet the latter is still firmly held in the clamping means, and the sheet is held during at least one revolution of the round bale table as a first step of packing the next round bale.
