Abstract

Bei einer Näheinheit zum Einarbeiten von Mehrweite in einer einzelnen Nähgutlage wird nach Eingabe der Ausgangslänge der Nähgutlage und der nach dem Raffen und Nähen gewünschten Solllänge von einem Rechner der Näheinheit der hierfür erforderliche Raffwert errechnet. Ferner wird zur Steuerung des Endpunktes eines Mehrweiteabschnittes die tatsächliche Stichanzahl errechnet. Hierfür wird aus einem Datenspeicher der jeweils aktuelle tatsächliche Stichlängenwert ausgelesen, bei dem der raffwertabhängige Schlupf der Transporteure der Nähmaschine berücksichtigt ist.

Figure 00000001
In the case of a sewing unit for incorporating fullness in a single layer of sewing material, after entering the starting length of the layer of sewing material and the desired length desired after gathering and sewing, the gathering value required for this is calculated by a computer of the sewing unit. Furthermore, the actual number of stitches is calculated to control the end point of a fullness section. For this purpose, the current actual stitch length value is read from a data memory, taking into account the slip-dependent slip of the feeders of the sewing machine.
