  • Method and apparatus for automatically placing sheets of plastic from a roll onto the second top tier of a lumber package
    Patent number: 6138438
    Abstract: An apparatus for automatically placing lengths of poly sheet from a roll of poly sheet onto the second-from-the-top tier of a lumber package includes a poly roll holder, and a plurality of grip clamps. The grip clamps may have rubber pads for improved friction when gripping the POLY sheet. The gripping clamps are mounted on a carriage which is in turn mounted on a trolley. The trolley is selectively translated back and forth over an exposed tier in a stack of lumber. The gripping clamps grasp the free end of the poly sheet so that the ploy sheet is drawn over the exposed tier as the trolley is translated.
