Abstract

Per adattare in modo ottimale, in una macchina per cucire in operato a disegno, il sistema sensore per esplorare il disegno della stoffa al disegno stesso, l'operazione di cucitura è preceduta da una fase di regolazione, durante la quale il sistema sensore è indotto ad esplorare il disegno. In base ai valori di segnale così acquisiti si regola l'amplificazione e/o l'offset del sistema sensore in modo che il campo di variazione di ampiezza risulti massimo. Di preferenza, dopo ciascuna regolazione si esamina se i segnali ottenuti con tale regolazione rispondono ai requisiti per l'ulteriore elaborazione ai fini del calcolo e della correzione di un eventuale errore di combaciamento del disegno.Fig. 1.In order to optimally adapt the sensor system to explore the design of the fabric to the design in a sewing machine in the design, the sewing operation is preceded by an adjustment phase, during which the sensor system is induced to explore the drawing. Based on the signal values thus acquired, the amplification and / or offset of the sensor system is adjusted so that the amplitude variation range is maximum. Preferably, after each adjustment, it is examined whether the signals obtained with this adjustment meet the requirements for further processing for the purpose of calculating and correcting a possible mismatch of the drawing. 1.
