Abstract
A method for wrapping a bale or the like with a wire or band held together by a tubular seal is described wherein wire is pushed through a metal tube held in readiness, then looped around the bale, and the free end of the wire is again moved through the metal tube. After the wire has been passed twice through the metal tube held in readiness; the wire feed is arrested by means of a limit switch; the portion of the wire end projecting out of the crimping jaws is bent around the metal tube; and tightening around the band is completed. Then the seal is produced by moving the crimping jaws toward each other and simultaneously severing the band from the supply coil. The wrapping operation takes place fully automatically. For this purpose, an apparatus is provided which holds the respectively next needed metal tube exactly into the path of movement of the wire to be extended around the bale.
