Abstract
In a wrapping machine comprising a ring rotatable on a frame, a ledge to support a package being wrapped, and a carriage supporting a roll of plastic film and movable with the ring to wrap the film around the ledge and around a package supported thereby, a severing arm, pivotable between a horizontal position underlying the ledge and a vertical position, carries a heated severing wire. Also, a spacing arm, pivotably movable between a horizontal position underlying the ledge and a vertical position, spaces an outer film layer from the ledge. In one embodiment, the severing arm carries heated welding elements, and the spacing arm applies a partial vacuum to cause a severed film portion to adhere to the spacing arm. In another embodiment, the severed film portion is clamped between the spacing and severing arms.
