Abstract

L'invenzione riguarda un dispositivo d'impostazione dell'avanzamento per macchine da cucire con una pluralità di organi d'impostazione agenti su alberi di posizionamento, ove l'elemento d'impostazione è formato da una leva di posizionamento e da un elemento a camma di posizionamento, con un valore minimo di avanzamento, impostabile ad uno degli alberi di posizionamento, ed un valore massimo di avanzamento selezionabile in anticipo. Sono previsti due organi d'impostazione accoppiati tra loro in modo tale per cui essi agiscono sullo stesso albero (22) di posizionamento, ed a questo possono impartire due posizioni angolari, e quindi due grandezze di avanzamento, e pertanto è possibile impostare un valore minimo di avanzamento ed in maniera temporanea, partendo da questo, un prestabilito valore massimo di avanzamento. Un elemento (2) a camma di posizionamento presenta una camma (29) di posizionamento per il punto di cucitura all'indietro, che può essere portata all'appoggio mediante una leva aggiuntiva (31) in luogo della camma (28) per il punto di cucitura in avanti.(fig. 1).The invention relates to a device for setting the feed for sewing machines with a plurality of setting elements acting on positioning shafts, where the setting element is formed by a positioning lever and a cam element positioning, with a minimum feed value, settable to one of the positioning shafts, and a maximum feed value selectable in advance. There are two setting members coupled together so that they act on the same positioning shaft (22), and can impart two angular positions to it, and therefore two feed quantities, and therefore it is possible to set a minimum value of advancement and temporarily, starting from this, a predetermined maximum advancement value. A positioning cam element (2) has a positioning cam (29) for the reverse sewing point, which can be brought to the support by means of an additional lever (31) instead of the cam (28) for the stitch stitching forward. (fig. 1).
