Abstract
L'invenzione concerne una capsula per spola del crochet di una macchina cucitrice a più aghi provvista di dispositivo di taglio e di morsetto per il filo del crochet. Essa risolve il problema di ritenere sotto tensione il filo del crochet svolto dalla spola di un ago escluso e, pertanto non utilizzato nel ciclo di cucitura, per la formazione di una scorta di filo limitata e temporanea, ma guidato per il taglio al morsetto ed ivi fissato, mantenendolo esente da carico. A questo scopo, nella parte superiore (1) della capsula, oltre ad una prima molla (7) per tendere il filo (6) del crochet una seconda molla (11) è disposta in modo che è mobile, oltre ché in una prima posizione (posizione di cucitura) determinata dal percorso del filo (6) durante la cucitura, ed in una seconda posizione determinata dalla formazione di un codolo di filo durante la fase di esclusione di uno degli aghi, è mobile in una terza posizione (posizione di riposo), in cui non agisce sul filo (6) del crochet tra la spola (16) ed il morsetto (23) e fuori dalla quale è mobile nella posizione di cucitura all'inizio del successivo ciclo di cucitura durante la formazione del primo allaggiamento tra il filo crochet ed il filo dell'ago mediante gli stessi contro la forza di molla.The invention relates to a bobbin spool capsule of a multi-needle sewing machine provided with a cutting device and a clamp for the hook thread. It solves the problem of keeping the thread of the hook unwound by the spool of an excluded needle under tension, and therefore not used in the sewing cycle, for the formation of a limited and temporary supply of thread, but guided for cutting at the clamp and therein fixed, keeping it free of load. For this purpose, in the upper part (1) of the capsule, in addition to a first spring (7) for tensioning the thread (6) of the hook, a second spring (11) is arranged so that it is mobile, as well as in a first position. (sewing position) determined by the path of the thread (6) during sewing, and in a second position determined by the formation of a tang of thread during the exclusion phase of one of the needles, it is movable in a third position (rest position ), in which it does not act on the thread (6) of the hook between the spool (16) and the clamp (23) and out of which it is movable in the sewing position at the beginning of the next sewing cycle during the formation of the first connection between the looper thread and the needle thread by means of them against the spring force.
