摘要： The invention is an improved apparatus for and method of wrapping boards in which a series of second sheets from a continuous supply roll of elongated sheet material precoated on one surface with an adhesive, are provided after partial lamination to the hitherto unwrapped surfaces of a succession of prewrapped boards and are subsequently completely laminated to such boards. A series of drive rolls move a succession of the prewrapped boards along a feed path to the nip of an anvil and a drive roll where a leading transverse edge of the sheet material adheres in registration to the unwrapped surface of a prewrapped board. A cutting knife severs the sheet material against the anvil to provide a cut portion of the sheet with a trailing transverse edge that will register with the back end of the board. Additional rolls are included for moving the board and adhered cut portion of the sheet away from the anvil and for pressing the board and the cut portion together to insure a positive wrap.
