Abstract
A sewing unit for working in extra width in a single fabric layer, wherein a necessary gathering value is calculated by a computer of the sewing unit after the entry of the initial length of the fabric layer and the desired length to be obtained after gathering and sewing. Furthermore, the real number of stitches is calculated to control the end point of an extra width section. The particular current real stitch length value, in which the gathering values dependent on slip of the feeders of the sewing machine is taken into account, is read for this purpose from a memory.
