Abstract
A method and device for creating uniform stitch lengths in an article being sewn by detecting actual feeding increments of the article using a sensor. With this information, the sewing or embroidery machine is controlled to provide generally uniform stitch lengths.
Claims21
Method for creating generally uniform stitch lengths with a sewing or embroidery machine, comprising
- providing at least one sensor directed at a surface of a fabric to be sewn;
- detecting actual increments of movement of the fabric by the at least one sensor and signaling a controller;
- controlling the sewing or embroidery machine with the controller to perform generally uniform stitch lengths based on the actual increments of movement detected by the sensor.

- controlling the sewing or embroidery machine with the controller to perform generally uniform stitch lengths based on the actual increments of movement of the fabric detected by the sensor.
A sewing or embroidery machine (1) for performing generally uniform length stitches in a fabric to be sewn, comprising:
- a housing with a lower arm and an upper arm, and a machine head located on the upper arm having a needle bar extending therefrom;
- at least one sensor supported by the housing for detecting actual increments of movement of the fabric and generate a detection signal;
- and
- a controller in communication with the at least one sensor to receive the detection signal which controls the sewing or embroidery machine to perform generally uniform stitch lengths based on the detection signal of the actual increments of movement of the fabric.
