A main support structure has a frame pivotally connected to it and extending upright, carrying a horizontal stacking bar for movement between an article receiving position extending laterally along the sewing table for receiving a sewn article from the sewing machine, and a retracted position spaced outwardly from the table. A clamping bar is carried parallel to the stacking bar by arm members pivotally connected to the frame for movement between an open position spaced from the stacking bar and a clamping position confronting it for gripping the sewn article therebetween.
