Abstract

Un dispositivo premistoffa per una macchina formatrice di punti con una molla disposta tra due elementi di appoggio per produrre la forza di spinta del piedino premistoffa, come pure con un meccanismo di azionamento per l'alzata e la discesa dell'asta premistoffa, è realizzato in modo che la molla da un lato durante l'operazione di cucitura permette un adattamento di posizione del piedino premistoffa allo spessore della stoffa, ma dall'altro lato al movimento di alzata e discesa dell'asta premistoffa non generi alcuna forza contrastante il movimento. A tale scopo, i due elementi di appoggio sono disposti spostabili in direzione longitudinale dell'asta premistoffa. L'elemento di appoggio superiore è collegato con il meccanismo di azionamento, il quale è bloccabile nella sua posizione corrispondente alla zona della posizione di lavoro del piedino premistoffa, mentre l'elemento di appoggio inferiore serve per alloggiare il piedino premistoffa e per effetto della molla poggia ad accoppiamento di forza contro un controsopporto, il quale è sopportato dall'asta premistoffa oppure è collegato con questa.A presser device for a stitch forming machine with a spring arranged between two supporting elements to produce the pushing force of the presser foot, as well as with a drive mechanism for raising and lowering the presser rod, is made of so that the spring on one side during the sewing operation allows an adaptation of the position of the presser foot to the thickness of the fabric, but on the other side to the raising and lowering movement of the presser rod does not generate any force counteracting the movement. For this purpose, the two supporting elements are arranged displaceable in the longitudinal direction of the presser rod. The upper support element is connected with the actuation mechanism, which can be locked in its position corresponding to the area of the work position of the presser foot, while the lower support element is used to house the presser foot and due to the effect of the spring it rests on a force coupling against a counter support, which is supported by or connected to the work clamp rod.
