Abstract
A method and apparatus for dispensing a top sheet and stretch wrapping includes a dispenser for dispensing a sheet from a roll of sheet material and a trough for receiving, containing and collapsing the dispensed sheet. A circulating bar draws the dispensed sheet from the trough over the top of a load by moving from a starting position to a finishing position above and across the top of the load while another bar returns from the finishing position to the starting position to position the dispensed sheet proximate to a hot wire which severs the sheet from the roll from which it is dispensed. A suspended flexible strip rests on top of the load for holding the sheet in place on top of the load. The trough, circulating bars and depending flexible strip are mounted on a frame which is movable in the vertical direction. A film web dispenser dispenses a web from a roll or sheet material and stretches the web, and a turntable rotates the load relative to the film web dispenser for wrapping the film web on the load and around the edges of the dispensed top sheet.
