A method and the device for acquiring and processing measurement quantities in a sewing machine () using at least one camera (), situated on a sewing machine (), for the acquisition and processing of image data for sewing machine elements and sewing elements. An image processing unit connected downstream from the camera () processes the images supplied by the camera (), taking into account data stored in a target quantity memory, and influences the behavior of the machine control unit dependent on the result of the processing.

Device and method for acquiring and processing measurement quantities in a sewing machine

A method and a sewing machine are provided to form sewing patterns allowing the stitching width to be changed during sewing for a flexible adjustment of parameters of the sewing pattern. In particular the stitch length a can be changed without changing the exterior design of the sewing pattern.

Method and sewing machine to form sewing patterns with adjustable stitch width

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.

Method and device for regulating material transport in a sewing or embroidery machine

A method and device for regulating the transport of material in a sewing or embroidery machine () that uses information from a position or movement sensor () located underneath the throat plate (). The controls for the sewing machine () calculate deviations of the actual feeding increments of the article to be sewn from the corresponding target values from the periodically read sensor signals. With this information, the feeding increments are regulated in such a way that the deviations are cancelled out by averaging.
