Abstract
A device for wrapping a bale or the like with a wire or band held together by a tubular seal comprises an arrangement of units 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 feeding of the metal tube held in readiness; the wire is arrested by 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 a supply coil. The wrapping operation takes place automatically by a holding device which holds the respectively next needed metal tube into the path of movement of the wire to be extended around the bale.
