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.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate patch library systems that may enable the storage and retrieval of patch configuration information. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

A sewing frame unit is provided. The sewing frame unit includes a frame support structure; a frame assembly affixed to the frame support structure; a machine carriage assembly mounted on the frame support structure. The machine carriage assembly provides for lateral and longitudinal movement of the sewing machine. A sensor is mounted on the machine carriage assembly or on the frame assembly for detecting a position of the sewing machine.

Disclosed is a guiding apparatus for use with a machine to facilitate performing an action along a self-guided path on a substrate. The guiding apparatus may include a support member configured to be attached to at least a portion of the machine. Further, the guiding apparatus may include one or more of lighting units, optical sensors, controllers, and user interface components, mounted on the support member, configured to identify an object, obtain position of the object on a substrate and perform an action along a self-guided path in association with that object on the substrate.

The present disclosure relates to a method for controlling the position of a seam contour and a device for carrying out the method, wherein the position control of a seam contour relative to structures of a sewing material is based on comparison data of a structure of a reference sewing material and a structure of a working sewing material.

In a first step, a needle pierces into an object to be sewed by reciprocal motion and leaves from the object to be sewed after the tip of the needle has penetrated therethrough. At this time, the needle is placed in a state of being stopped relative to the object to be sewed. In a second step, the needle leaves from the object to be sewed. At this time, the needle is moved relative to the object to be sewed along a sewing direction (sewing line).
