ABSTRACT:
A refeed system for use in a strapping machine for feeding a strapping material around a load, positioning, tensioning and sealing the strapping material around the load. The refeed system refeeds strapping material into feed elements. The refeed system includes a driven, rotatable boost wheel having a first diameter when in a stationary mode and a second, larger diameter when in a second, rotating mode and an idler element opposite of the boost wheel. When the boost wheel is in the stationary mode, a first gap is defined between the boost wheel and the idler element to permit the free conveyance of strap through the gap and when the boost wheel is in the second rotating mode a strap, positioned in the gap is engaged by the boost wheel and is conveyed through the gap.
