Palletless sewing methods and systems

Abstract

Various examples are provided related to transporting and sewing material in, e.g., automation of sewing robots. Multiple pieces of layered materials can be transported on a flat planar surface while maintaining the material layer's position and orientation relative to one another during a sewing procedure of these materials along any arbitrary seam shape. In one example, among others, a method includes positioning a second piece of material on a first piece of material located on a sewing plane, positioning a material holding apparatus over the pieces of material to secure position and orientation between the pieces of material, locating the pieces of material with respect to an automated sewing machine by repositioning the material holding apparatus, and sewing the second piece of material to the first piece of material. The methods can eliminate the need of custom-made templates for sewing arbitrarily shaped seams with an automated sewing machine.
