<p>A method and apparatus are disclosed for shredding reconstituted and blended leaf sheets, wherein the sheet (14) is first slit longitudinally (at 18), and then cut off transversely by bringing the points (62) of a serrated blade (60) into contact with the slit sheet at an angle to penetrate the sheet, and then moving the blade to tear off the portion of the sheet between the point of penetration and the end of the sheet. This produces much more uniform shreds, with less dust and shattering, than has hitherto been possible.</p> |
