Abstract
An apparatus in which material to have elastic applied thereto is carried by a first conveyor in one direction along a flow path. An elastic conveyor extending transversely of the material flow path is operable to continuously draw elastic from storage, tension it and carry it to a feeder head that reciprocates transversely of the flow path. A transverse elastic applicator receives elastic substantially continuously from the feeder head in a square-wave pattern and moves it toward the flow path. The elastic applicator has spaced guide members mounted adjacent opposite sides of the flow path to hold tensioned elastic therebetween extending transversely of the flow path as the elastic applicator moves the elastic to the flow path and applies the elastic to the material on the first conveyor. Cutters positioned inboard of the guide members sever the elastic after it has been applied to the material.
