Abstract
Apparatus and method for forming an elasticized portion of an article having a thermally-elasticizable strip along a marginal portion in which heated air is directed towards the strip at at least two different angles relative to the plane of the strip and at a velocity sufficient to cause oscillation of the marginal portion bearing the thermally-elasticizable strip; these conditions are maintained for a dwell time long enough to render the strip elastic when cooled to ambient conditions.
