Abstract
Apparatus for applying tensioned elastic to material including a first conveyor for carrying material in one direction along a flow path, a second conveyor operable to draw elastic from a storage container, tension the elastic, and move the elastic longitudinally in a tensioned state along a region extending transversely of and spaced from the first conveyor flow path, and a pair of transfer grippers. The transfer grippers are movable along a path in the direction of the flow path and are positioned to grasp spaced regions of elastic held by the second conveyor. Cutters are positioned laterally outwardly of the grippers to sever elastic from the second conveyor after being grasped by the grippers. The grippers maintain the elastic in a tensioned condition and deposit on the material. Also disclosed is a method for applying tensioned elastic to material, generally as described above in relation to the apparatus.
