In the sample cover bar χ swinging around g , cover pins are inserted as required; g are pointed screws, which are located in the arms m . The arms m are screwed tightly to the shaft h which oscillates around the bolt η and is laterally displaceable on the same. The lever s goes from the shaft h to the needle bar %. Lever s swings around bolt s ¹ , while at s " it has as many slotted holes as is necessary. In the rest position, lever s is to the side of the needle bar, dotted in FIG.

When the Röfschenschlitten c at every second row at the end of its path with the nose part 0 under the angle lever comes to rest ρ, it is by mediation of the pull rod b of the lever 5 to the right side, Fig. 2, swung out and comes with its lower to stand close behind the needle bar ^; so that now the pattern comforter Barre χ each forward and backward movement of the needle bar \ participate must,. As soon as the Röfschenschlitten c leaves its place again,. the angle lever ρ together with the pull rod b and lever S also return to their rest position, the needle bar \ passes by s and the chair works without a pattern. The lateral displacement of the shaft h and thus at the same time the sample bar χ is done by a wheel α provided with eccentric blades a ¹ and rotatable about i. On the same there is still the ratchet wheel f, in which the pawl t engages. The eccentric leaflets a ¹ are embedded in one or more needle divisions in the wheel α as required and thus represent an interrupted screw on their end face.

The leaflets α ¹ engage in a gap located in the shaft h , one side of which is always pressed by the spring h ¹ against the leaflet α ¹ that is currently engaged. If the pawl rotates the wheel so that another leaf α ¹ comes into engagement, then the shaft h must move laterally according to the dimensions of the new leaf a ¹ and with it the sample cover bar. The one swinging around e. Lever d mediates the pressure of the deckers on the chair needles when uncovering, through the part ν. The deck mechanisms k / performs its functions as usual. Is at k lever k. ¹ On the same the train t ¹ goes on a bolt, which pulls the pawl t down when going down and thereby prevents the wheel α from advancing during the reduction.

If the sample bar is to come into action differently than in every second row, instead of the parts ν and b and the lever p ', a switching mechanism must be attached which allows the lever s to swing in or out as often as desired and at the same time to move the pawl t regulated. Since one is bound to a recurring pattern by a wheel, the eccentric wheel a can also be replaced by a mechanism which allows the pattern covering machine to be moved in any way and order so that the pattern is not repeated in its entire length.

The work takes place in the following way: As soon as the Röfschenschlitten c has almost reached the end of its return path, it hits with the nose part ο against the inclined surface of the angle lever 2 ?; the same is lifted by the further movement of the slide and, by means of the pull rod b, brings the lever s to swing out to the side behind the needle bar.

If the needle bar { recedes, the pattern needle bar χ must follow it. As soon as the tips of the cover needles have entered between the sinkers, FIG. 3, lever d loosens as much as necessary and the spring u presses the cover needles d ¹ onto the chair needles; the strength of the pressure taking place can be regulated by the counter screw ^{v 1.}

As the movement continues, the top needles take the newly cultivated loops as well as the old meshes, because the new meshes cannot go under the Tips of the needles arrive because the cover needles are on the relevant tips; it arise from the fact that the old meshes cannot fall off, so-called twill or Double stitches which get caught on the top needles, Fig. 4.

When the needle bar has now reached its cut-off position, the lever d presses ν and the cover needles rise above the cut-off combs q in the position that they must assume when covering, Fig. 5. Now the pawl / eccentric wheel α turns and the entire pattern covering machine is shifted to the left or right by one or more needle divisions, depending on the size of the newly engaged leaflet a ^1. After this has happened, lever d slows down again, spring u presses the cover needles onto their new chair needles, and the needle bar, together with the sample cover bar, goes back into its cooler position. During the next row, wheel α is again rotated by one division by pawl t , so that the sample cover bar then assumes the position it is in again according to the measure of the leaflet a ¹ moving into the gap in shaft h . should have in the following series of patterns.

In this way, very different kinds of thread entanglements can be created, only two of which are shown in FIGS. 6 and 7.

. Fig. 7 shows the entanglement of the threads in the case when one needle is around the other every other row is covered by the cover needle and the double stitches removed without Displacement of the needle bar can be uncovered again on the same chair needles.

In the interlocking shown in Fig. 6, one needle also has a cover needle around the other and the pattern bar χ also comes into operation in every other row, but here the lifted double stitches are not uncovered again on the same chair needles as in Fig. 7, but once on the right neighbor needle, the next time on the left neighbor needle, so that in this way the chair needles a ^s a ³ only form double ^{handles to 2} , which are then worked on the needles έ ² £> ² into triple stitches m ^a .

The covering is not done here as it is when reducing or producing Petinet patterns during a special tour of the chair, the so-called minor row, in which no stitches are formed, rather it takes place between the pace of teeing off and . Including the work tour, whereby the delivery of the chair by the Patterns is not reduced. '

If it is necessary to remove the sample covering bar for the purpose of pushing up, inserting the needle, etc., the pull rod b must be unhooked from the angle lever ρ and pushed sideways enough that lever s comes to lie parallel to the shaft h and then the whole sample covering machine is moved around the bolts η can swing out at the top.

The play of the tools (chair needle α ³ , Petinet needle d ¹ , press k ¹ , plate p ¹ ) in their effect on the goods w ^x "and the new row of stitches to produce the sample goods is shown in FIGS. 3 to 17 graphically represented.

After the goods n> ^{x has been} enclosed, ie held by the sinkers p ¹ at the back while the chair needles go forward, the thread / ^{1 is} inserted as usual, FIG. 8, and from the sinkers p ¹ the new row of stitches m ° culminated, Fig. 9.

Then the cover needles or Petinet needles d ¹ lie on the same opposing chair needles a ³ , Fig. 10, go back with the chair needle contour and initially take the new stitch m °, Fig. 11, and when moving on also the old stitch m ¹ on, Fig. 12..

So that the needles, which are not covered by any Petinetnadel in which the position of FIG. Following 11 moment, Fig. A, in which the new stitches 11 lie under the tips of the needles £> ² and before the old commodity w ¹ under the If chair needle tips are pressed, the press k ¹ goes down at this moment.

^{The fact that the needles a 3} , which are already pressed shut by the Petinet needles, are also hit by the press only causes the needles a ^{3 to} bend deeper during pressing and has no effect on the formation of double or pre-fusing stitches.

Claims (2)

After the chair needles and the cover needles have reached the extreme left position, Fig. 13, in which case the double mesh m ° m1 = m2, Figs. 4 and 5, is no longer on the chair needle, the cover needles are raised so high that the Tee comb no longer prevents the lateral displacement of the same, whereupon the needle needles move sideways by one or more needle divisions, FIG sinkers p1 that are moving down are enclosed between knock-off comb q and sinkers p1 and combine with the mesh m ° that was already present on b2 to form a triple mesh m3, Fig. 6, 15, 16 and 17. 1. A process for the production of Prefs-Petinet - patterns in which the Petinet needles already the only culverted handles (not the already finished stitches) together with those on the corresponding chair needles the hanging stitches of the old goods. 2. A mechanical pen chair used to carry out this process, in which the petinet needles temporarily move together with the associated chair needles in their axial direction. For this purpose 2 sheets of drawings.
