Abstract
An apparatus and method for shirring netting onto a netting tube. A second tube is placed over and coaxially to the netting tube and netting is stretched over the second tube. The two tubes are caused to move in a reciprocating manner through a plurality of spring-loaded fingers, which allow the netting to pass on the downstroke and hold the netting on the upstroke. As the two tubes move, the netting is pulled over the second tube and shirred onto the netting tube. An annular space formed by a tube ring placed between the netting tube and the second tube causes the netting to shir in multiple, neatly aligned layers.
