Until "firing" relates to an auxiliary device: for sack nosing for stapling machines with a Sciialtrad and a ratchet driving the latter, which is controlled by a sink control wheel and a control pawl, which is loosely seated on the axis of the ratchet wheel. "has deep tooth gaps" which allow the single grip of the pawl into the tooth gaps of the ratchet wheel and which has less deep cream gaps "which tots the pawl. Prevent engagement in a tooth gap of the ratchet wheel.

Known sickzag apparatus of this type have a toothed ratchet control wheel finite at least two deep tooth gaps arranged one behind the other, so that at this point a pad is guided in the zigzag without any g-eradea stitches during the lähening process ψ ±? Ά. Such a stitch is called a knurled stitch. "The hand stitch seam is not suitable for finer types of fabric, especially Perlon, because it does not have sufficient elasticity. The innovation avoids this TTacli part *

The Slink ens ring gear is suitable for firing between all depths Tooth gaps each have at least one flat tooth gap, so that one or more G-ersdeau.sstiches after each side stitch

arsequences · This type of stitch can be referred to as reversible stitching. Am sewn in this way fine (Jewebe is in the seams. Senr elastic and "has a large 3-seam strength * with the reversible stitch can create very appealing stitch effects on the top of the fabric getting produced"

It has been shown to be especially useful that the new Sinkens teuerr ad three deep tooth gaps "which one below the other are each separated by three flat tooth gaps.

It is very difficult to arrange two or more different types of ratchet control wheels next to one another, so that the stitch type can be changed through the transition of the control ratchet from one ratchet control wheel to the other without having to change the ratchet control wheels the diameter of the Elimken control wheels · As a modification of this arrangement, a rotatable roller can be provided with at least two different ratchet control wheel rims, which preferably have a guide ring © on both sides »

This arrangement makes it possible to use different types of devices without spending a great deal of time Set turning stitches. Any remodeling work at the Susatzappar-at are omitted in the TM production, those between the Washers arranged on the steering wheels have the purpose of to separate the ratchet control wheels in such a way that an unintentional skipping of the pawls from one ratchet control wheel to the other is excluded «with the arrangement of ratchet steering wheel rims on a rotatable roller offers the gate part that with a few

In Figures 1, 2 and 3, the additional device with a built-in ratchet control wheel 1 according to the innovation is shown »which has two deep marks * which are each followed by five flat Üüeken * The ratchet control wheel Ί lies between a wheel 15 and a brake spring 7 _r which * can be adjusted through a nut 8 ₉ more or less strongly pressed Depending on the requirements on the Klinkensteuerrad 1 · Semäss Jigur 2 accesses the control pawl 9 in the deep gap 2 of the pawl control wheel 1 a _r shown during dug in Ligur 1 is the same control pawl 9 »tremor of the control latch 9 there is a switching pawl 10 » in. The recess 11 of which comes into contact with a spring-locked attachment 12 attached to the control pawl 9 for the purpose of coupling the two pawls when turning stitches are generated. The pawl 10 also has a locking hole 25 * into which the projection 12 of the control pawl 9 is locked if the control pawl 9 is to be continuously disengaged · In this case, a zigzag seam is produced without straight cutouts. pivotable- lever arm 16 is a bolt 1? arranged around which the pawls 9 and 10 are pivotable · fixed in line at 18 «Seder 14 can push the pawl 10 into the gaps between the teeth of a ratchet wheel 15.

The new ratchet steering wheel 1 in accordance with FIG. 5 has three deep gaps 2 * each followed by three flat squares 3. It produces a turning stitch according to Pigur 6. In FIG. worked out by drilling * Between these ratchet control wheel rims 5 there are guide rings © 6 with a large diameter * which serve as a guide for the control pawl 9 * The mode of action is as follows: The Badelstaiige 22 moves up and down.

During the next downward gear of the needle bar 22, the control pawl slides over the subsequent tooth of the left-hand steering wheel 1 * while when the needle bar 22 goes up, it engages the next flat gap in the ratchet control wheel i and turns it clockwise by one tooth width * Me flat gaps generally designated with 3. The entrainment of pawl control wheel 1 during the rotation of the control latch 9 in the counterclockwise direction is prevented by the braking action of the brake spring 7 »The spring-positively connected with the control pawl 9 pawl 10 with the indexing wheel 15 is no longer engaged, as the control pawl 9, the pawl 10 in the field of
