Abstract: A stack of workpiece fabrics carried on a mobile cart is brought to a sewing machine having a work surface spaced above the table surface of the cart on which the fabric is supported. An air powered lift mechanism mounted on the sewing machine and engaged with the cart elevates the cart to an upper tilted position for easy transfer of the work from the table surface of the cart to the work surface of the sewing machine. Fabrics on which work has been completed may be transferred by air powered apparatus to a cart for transport to another station.
