ABSTRACT:
A stacker for seizing and successively stacking sewn articles received from a sewing machine. 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. An air cylinder serves as a driving motor or prime mover for causing movement of the clamping bar to its clamping position, subsequent movement of the stacking bar to a retracted position by pivotal movement of the frame relative to the main support structure, and thereby seizing the received sewn article and pulling it from the sewing table and stacking it upon the stacking bar. Such cylinder then causes ultimate return movement of the stacking bar to its receiving position together with movement of the clamping bar to its open position in readiness for receiving another sewn article overlying the first.
