Description

Device for automatic working of the long row on flat knitting looms .When knitting stockings, the heels are knitted on flat knitting chairs or a particularly long row of stitches worked at the tip, which makes it easier Belching when chaining is used. This series is generally automatic from the Counting chain for covering controlled and is therefore called an automatic long row. To cultivate this long row such a knight drive is needed that a sufficiently long stitch is formed by the sinker before the next sinker seizes the thread, otherwise it will tear. The strong knight instinct is for the usual work very inconvenient, the speed of the sinkers in the last Moment becomes too big and threatens to tear the thread with finer machines. So there is a need when producing a stocking because of an or having to work two long rows up to 2000 rows with an inconvenient knot.

On the other hand, there are devices for reducing the operating speed of flat knitting looms when performing certain work processes (blankets) generally known per se and form the prerequisite for the present invention, the basis of which is the knowledge of the relationship between the depth of the kule and the shape of the knurl and the slow working of the long row can be seen.

Accordingly, there is the essential feature of the subject matter of the invention in that the long row using a knight with a flatter drive curve, than required for a long row at normal working speed is; it works so slowly that the thread is overloaded is avoided during the killing of the long row. The previous lever is for this purpose for the long row on the deck bracket so united with the lower lever that the lower switch with the mediation of the lower pull either from the long row lever or from the lower lever can be influenced.

The subject of the invention is illustrated in more detail in the drawing, namely Fig. r shows the Rössel drive and the associated Rössel shape for ordinary Rows, Fig. 2 the knurl drive together with knurled shape for the long row with ordinary Working speed, Fig. 3, that worked with the knot for ordinary rows Long row.

Fig.q. FIG. 13 is a side view of the conventional arrangement of the FIG Counting chain influenced long row lever, and Fig. S is a corresponding side view the new facility.

For smooth work, i.e. H. for the up to 2,000 ordinary rows of a stocking, the knight according to Fig. z with the drive k is desirable because with this the sinker speed and thus the thread stress is very low is. But since to work the one or two long rows the knot according to Fig. 2 with the drive k 'is needed, on the other hand, a change of the Rössel without further ado is not possible, one is forced to work the whole stocking with this knight. Especially at higher speeds the machine or fine goods the thread stress by this knight is like this'. strong that a tearing or Cutting the thread can take place.

If you wanted to work with the knight according to Fig. Z without further ado, so with the long row the thread would break even more, because the first one! circuit board still needs thread, while the second is already tensioning the thread (see Fig. 3). Will but if the long row worked slowly in this case, it remains the same Picture, however, it will reduce the stress on the thread as a result of the generally reduced Working speed and the associated lower board speed so little that the thread for the first sinker could be pulled around the second without Overuse can take place. There is then the possibility of the up to 2ooo work smooth rows with the flat knurl as shown in Fig. x.

Although in general the problem had already been solved, any one to work more slowly in particular individual work processes (reduced or covered pass), so far no value has been placed on the slow gear, especially with the long series because the knowledge of its value as well as the resulting consequences was missing.

In the known device according to Fig. 4, a button acts on the counting chain that runs on the chain wheel b of the axis a . on the angle lever h, which is arranged swingably on the axis g, in order to initiate the work of the long row by means of a train e which leads to the long row eccentric. For easier actuation, the horizontal arm of the lever la has an approach d on its underside.

Deviating from this, according to the invention, as can be seen from Fig. 5, the horizontal part of the angle lever h is extended and so connected to the train f that leads from the lower switch na or its lever i to the lower lever l that either independently of one another the lower lever or the long row lever can set the switch m.

Claims (2)

PATENT CLAIMS: e.g. Device for automatic working of the long row on flat knitting looms, characterized in that the long row using of a knight with a flatter drive curve than for a long row with an ordinary one Working speed is required, work is carried out so slowly by itself, that overstressing of the thread during the killing of the long row avoided will. 2. Apparatus according to claim x, characterized in that the lever for the long row on the deck bracket is so united with the minor lever that the minor switch with the mediation of the lower pull (f) either from the long row lever or from the lower lever can be influenced.
