Abstract: Due to rapid advancement in computing technology of both hardware and software, the labor intensive sewing process has been transformed into a technology-intensive automated process. During an automated process, processing of a work piece can be visually monitored using a sensor system. Data gathered from the sensor system can be used to infer the condition and/or position of the work piece in the work area using, e.g., models of a sensor profile. Evaluation can be carried out before processing begins, during processing and/or after processing of the work piece. Examples of systems and methods are described that provide for initially and successively matching the model of the expected shape for a product work piece to a set of sensor readings of the work piece in order to determine the position of the work piece and support a variety of useful features.

Abstract: Apparatus and a concomitant method for sewing seams in upholstered furniture such as mattresses. The apparatus contains a sewing machine located adjacent a conveyor belt which moves the mattress in a linear direction beneath the sewing machine, a presser arm for turning the mattress, and a fastening cylinder for temporarily attaching the mattress to the presser arm during the turning process.

A sensor indicates when a corner of the mattress approaches the sewing machine. When the sensor indicates the approach of the corner, the conveyor belt is halted and the motor changes to a slower speed such that the sewing speed is slowed. Simultaneously, the fastening cylinder temporarily attaches a presser arm to the mattress.
