Abstract
A machine for applying elastic to material is provided that includes a conveyor for carrying material. The conveyor moves the material in one direction along a flow path. An elastic band storage with a plurality of elongate elastic bands is provided for application to the material. An elastic feeder has a feeder head that feeds the plurality of elastic bands directly onto the material while the feeder head moves laterally across the flow path. The lateral movement of the feeder head across the moving conveyor applies the elastic bands to the material in a curved contour. The feeder head is operable to feed the elastic bands onto the material while maintaining a selected spacing between individual elastic bands throughout the curved contour.
