发明名称 Protective cover for stacked lumber
摘要 A protective covering for a lumber stack is constructed by providing an appropriately sized sheet of heavy duty heat shrinkable plastic material, folding the side edges of the plastic sheeting material inwardly along spaced apart longitudinally extending lines to form top and bottom layers and joining the ends of the top and bottom layers to define a top layer which is imperforate throughout its entire length and width and a bottom layer which is imperforate throughout its entire length and width except for an opening extending the longitudinal center line of the bottom wall from end to the other. A lumber stack is received through the opening in the bottom wall thereby forming initially upwardly extending rectangularly shaped panels which are folded downwardly and secured to the ends of the lumber stack. The portions of the plastic sheeting extending adjacent the ends and the corners of the lumber stack are then heated to shrink the plastic sheeting into secure engagement with the lumber stack.
