摘要

The invention relates to a sewing device, comprising a holder for the material to be sewn. The outer contour of said holder corresponds to the dimensions of the material to be sewn to be held therein. Said holder can be displaced in relation to a sewing needle by means of a control device and using X-Y-drive motors. According to the invention, an information support (chip 28) is provided on the holder for the material to be sewn (5, 6, 7). This information support has all of the information required for controlling the sewing device, for calculating and sewing the seam according to the contour of the holder for the material to be sewn (5, 6, 7). The inventive sewing device comprises a sensor device (read head 29) that is designed for reading out the information from the information support (chip 28) and supplying it to an input of the control device.
