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.

Abstract: A wrapping apparatus having a rotating ring which carries a film dispenser carriage adapted to dispense film web around a load carried on a wrapping conveyor. A traveling film clamp mechanism is mounted adjacent the wrapping conveyor and extends through the plane of the rotating ring to engage, clamp, cut and brush film web dispensed from the film dispenser carriage. The traveling film clamp mechanism incorporates a linear driver assembly, a fixed clamp jaw mounted to the linear driver assembly and positioned substantially parallel to the line of travel in which the linear driver operates, a rotating jaw mounted to the linear driver assembly adapted to close against the fixed jaw to clamp film web therebetween, and a rotating cutter brush arm carrying a leading cutter edge and a trailing brush.
