Abstract
Method and apparatus for wrapping a signature bundle by moving a wrapping sheet into the path of movement of a bundle, said sheet being maintained in self-supporting fashion by imparting a bend thereto as it is fed to the wrapping station. The bundle "crashes" into the sheet causing it to collapse and wrap itself about the bundle. When the wrapping operation is completed, the wrapping sheet is wrapped around three contiguous surfaces of the bundle. The sheet is automatically cut and a new wrapping operation is initiated. The wrapping sheet may be printed upon by an ink jet printing characters "on the fly". The characters are printed backwards and "bleed through" the wrapping sheet to appear in normal manner.
