Abstract

Una macchina è provvista di un dispositivo di azionamento per l'asta porta-ago, e di un dispositivo di regolazione per modificare la corsa dell'asta porta-ago, ed a tale riguardo il dispositivo di regolazione s'impegna su una parte di meccanismo del dispositivo di azionamento, per modificarne la lunghezza di leva efficace. La macchina per cucire presenta inoltre un dispositivo di azionamento per l'organo di alimentazione del filo, conformato come meccanismo articolato. Tanto il dispositivo di azionamento per l'asta porta-ago quanto il dispositivo di azionamento per l'organo di alimentazione del filo debbono essere sviluppati in modo che l'impostazione dei due dispositivi di azionamento possa essere effettuata con un unico intervento di regolazione. A tale scopo il dispositivo di regolazione, per adattare il movimento dell'elemento di guida del filo, nell'organo di alimentazione del filo medesimo, al movimento dell'asta porta-ago, è accoppiabile al dispositivo di azionamento per l'organo di alimentazione del filo, per modificare la lunghezza di leva efficace di una parte di meccanismo del dispositivo di azionamento dell'organo di alimentazione del filo.Fig. 2A machine is provided with an actuation device for the needle-holder rod, and with an adjustment device for modifying the stroke of the needle-holder rod, and in this respect the adjustment device engages on a part of the mechanism of the operating device, to modify its effective lever length. The sewing machine also has an actuation device for the thread feeding member, shaped as an articulated mechanism. Both the actuation device for the needle-holder rod and the actuation device for the thread feeding member must be developed so that the setting of the two actuation devices can be carried out with a single adjustment intervention. For this purpose, the adjustment device, to adapt the movement of the thread guide element, in the thread feeding member, to the movement of the needle-holder rod, can be coupled to the actuation device for the feeding member of the thread, to modify the effective lever length of a part of the mechanism of the actuation device of the thread feeding member. 2
