PCT No. PCT/SE82/00105 Sec. 371 Date Dec. 20, 1982 Sec. 102(e) Date Dec. 20, 1982 PCT Filed Apr. 5, 1982 PCT Pub. No. WO82/03878 PCT Pub. Date Nov. 11, 1982.An electronic sewing machine for performing fancy seams, such as button holes, is provided with a memory and data circuits for the control of the stitch forming instrumentalities and has a common control for an individual length adjustment of two portions similar to one another of the fancy seam. The control actuates two programmable memories for stitch lengths in such a way that during sewing a first portion the control is connected to a first one of these memories for storing of data, and during sewing the second portion to the second memory. As the storing of data remains until new data is introduced, one and the same fancy seam can be repeated in conformable performance for an unlimited number of times. |
