An Independent claim is also included for remotely controlled operation of the lower drive pins, e.g. by a pneumatic actuat to bring the shuttle in and out of operation.

Description

Die Erfindung betrifft eine Schiffchenstickmaschine mit einer Treiberbalkeneinheit, welche einen Treiberbalken aufweist, in welchem für jede Stickstelle ein unterer Treibernagel und ein oberer Treibernagel angeordnet ist, wobei mindestens einer der Treibernägel im Treiberbalken verschiebbar ist (siehe Dokument EP-A-0 638 681).The invention relates to a shuttle embroidery machine with a Driver bar unit, which has a driver bar, in which for each A lower driver nail and an upper driver nail are arranged, whereby at least one of the driver nails can be moved in the driver bar (see Document EP-A-0 638 681).

Schiffchenstickmaschinen arbeiten nach dem Zweifadensystem, d.h. mit einem Nadelfaden und einem Schiffchenfaden, wobei der Nadelfaden bei jedem Stich mit dem Schiffchenfaden verschlungen wird. Eine mit einem Oehr versehene Nadel transportiert den Oberfaden durch den Stoff hindurch, wo der Faden beim Zurückgehen der Nadel eine Schlaufe bildet. Durch diese Schlaufe wird dann das Schiffchen, in welchem der Schiffchenfaden enthalten ist, hindurchgeführt. Eine Schiffchenstickmaschine enthält eine grosse Anzahl von Stickstellen und dementsprechend viele Nadeln und Schiffchen. Zur Hin- und Herbewegung der Schiffchen dient der Treiberbalken, welcher für jedes Schiffchen einen unteren Treibernagel und einen oberen Treibernagel aufweist, zwischen denen das Schiffchen angeordnet ist. Mit diesen Treibernägeln wird das Schiffchen in der Schiffchenbahn des sogenannten Stöcklis auf- und abbewegt.Shuttle embroidery machines work according to the two-thread system, i.e. with a Needle thread and a shuttle thread, the needle thread with each stitch is devoured with the shuttle thread. One with an ear The needle transports the upper thread through the fabric, where the thread at Retraction of the needle forms a loop. Through this loop, that becomes Shuttle, in which the shuttle thread is contained, passed through. A Shuttle embroidery machine contains a large number of embroidery points and accordingly, many needles and boats. For the back and forth movement of the The driver bar is used for the shuttle, which has a lower one for each shuttle Driver nail and an upper driver nail, between which the Shuttle is arranged. With these driver nails, the boat in the Shuttle train of the so-called Stöcklis moves up and down.

Bei der in den Figuren 1 und 2 gezeigten bekannten Treiberbalkeneinheit wird der Treiberbalken 11 durch ein Stahlrohr gebildet. Die unteren Treibernägel 13 sind mit einer Schraubverbindung am Treiberbalken 11 befestigt. Die oberen Treibernägel 15 sind in einer Führung 19 verschiebbar gelagert. Mittels einer Mutter 23 kann der Druck einer Feder 25 verstellt werden, um die Kraft zu regulieren gegen welche der obere Treibernagel 17 verschoben werden kann.In the known driver beam unit shown in FIGS. 1 and 2, the Driver beam 11 formed by a steel tube. The lower driver nails 13 are attached to the driver beam 11 with a screw connection. The top Driver nails 15 are slidably mounted in a guide 19. By means of a Nut 23, the pressure of a spring 25 can be adjusted to the force regulate against which the upper driver nail 17 can be moved.

Wie die Explosionsdarstellung von Figur 2 zeigt, sind ausser den bereits aufgezählten Teilen noch eine Anzahl weiterer Teile notwendig, um die Treibernägel am Treiberbalken zu montieren. All diese Teile tragen natürlich zu einer unerwünschten Erhöhung der Masse der Treiberbalkeneinheit bei. Sie stellen auch einen erheblichen Kostenfaktor dar und komplizieren zudem die Lagerhaltung von Ersatzteilen. Als besonders nachteilig hat sich auch die arbeitsintensive Justage der Treibernägel auf dem Treiberbalken erwiesen.As the exploded view of Figure 2 shows, besides those are already parts listed a number of other parts necessary to complete the Mount driver nails on the driver beam. Of course, all of these parts contribute an undesirable increase in the mass of the driver beam unit. she also represent a significant cost factor and also complicate the Stock of spare parts. This has also proven to be particularly disadvantageous Labor-intensive adjustment of the driver nails on the driver beam has been proven.

In den letzten Jahren sind die Geschwindigkeiten, mit denen Schiffchenstickmaschinen arbeiten, ständig erhöht worden. Galten noch vor wenigen Jahren 185 Stiche pro Minute bei grossen Maschinen und 250 pro Minute bei kleinen Maschinen als obere Limiten, werden heute 600 und mehr Stiche pro Minute angestrebt. Verschiedene Faktoren stellen sich aber einer starken Erhöhung der Maschinendrehzahl entgegen. So kann die Masse der Treiberbalkeneinheit nicht beliebig reduziert werden, ohne deren Stabilität zu gefährden. Des weiteren muss sich eine die Masse der Treiberbalkeneinheit reduzierenden Neukonstruktion auch in einem entsprechenden Kostenrahmen halten.In recent years, the speeds have been at Shuttle embroidery machines work, have been constantly increased. Still apply 185 stitches per minute for large machines and 250 per Minutes for small machines as upper limits are 600 and more today Stitches targeted per minute. However, there are various factors counter strong increase in machine speed. So the mass of Driver beam unit can not be reduced arbitrarily without their stability compromise. Furthermore, the mass of the driver beam unit must be reducing redesign also in a corresponding budget hold.

Es ist daher Aufgabe der vorliegenden Erfindung eine Schiffchenstickmaschine mit einer Treiberbalkeneinheit zu schaffen, die ein Arbeiten mit hohen Drehzahlen ermöglicht und trotzdem eine kostengünstige Herstellung erlaubt.It is therefore an object of the present invention to provide a shuttle embroidery machine to create with a driver beam unit that works at high speeds enables and still allows inexpensive production.

Erfindungsgemäss wird dies bei einer Schiffchenstickmaschine der eingangs erwähnten Gattung dadurch erreicht, dass der Treiberbalken aus einem Profil besteht und dass die Treibernägel in Bohrungen des Profils eingesetzt sind. Das Profil kann beispielsweise aus einer Aluminiumlegierung bestehen. Das Profil und die Bohrungen im Profil können mit hoher Genauigkeit hergestellt werden, so dass die bisherigen komplizierten Justierarbeiten für die Einstellung der Treibernägel entfallen. Dies stellt nicht nur eine bedeutende Kostenersparnis dar, sondern es wird auch noch das Gewicht für die bisher nötigen Befestigungsmittel für die Treibernägel eingespart.According to the invention, this is the case at the beginning of a shuttle embroidery machine mentioned type achieved in that the driver bar from a profile exists and that the driver nails are inserted in holes in the profile. The Profile can for example consist of an aluminum alloy. The profile and the holes in the profile can be made with high accuracy, so that the previous complicated adjustment work for the adjustment of the Driver nails are eliminated. This not only represents a significant cost saving, but it also becomes the weight for the previously required fasteners saved for the driver nails.

Vorteilhaft weist das Profil Rastmittel, z.B. eine Rille oder eine Rippe auf, welche mit entsprechenden Rastmitteln des Treibernagels kooperieren können, um den Treibernagel in der gewünschten Stellung zu arretieren. Das Profil des Treiberbalkens weist vorteilhaft einen Hohlprofilteil und zwei unten am Hohlprofilteil angeordnete Schenkel auf. Der obere Treibernagel kann im Hohlprofilteil und der untere Treibernagel in den Schenkeln angeordnet sein. Ein solcher Treiberbalken hat eine hohe Stabilität bei relativ kleiner Masse, und die Anordnung des unteren Treibernagels in den Schenkeln ermöglicht es, diesen aus zwei Teilen zu fertigen, wie dies nachfolgend beschrieben wird. Vorteilhaft weist der Treibernagel eine Rastfeder auf, welche mit den Rastmitteln des Profils kooperieren kann. Der Treibernagel kann einen Betätigungslappen aufweisen. Eine Massereduktion und eine bessere Masshaltigkeit und Formstabilität wird erreicht, wenn der Treibernagel mindestens über einen Teil seiner Länge, insbesondere in dem im Profil beweglichen Teil, hohl ist. Mit grossem Vorteil ist der Treibernagel, z.B. der obere Treibernagel, mit Rastfeder und/oder Betätigungslappen einstückig aus Kunststoff geformt. Dadurch lässt sich eine sehr hohe Kostenersparnis erzielen. Am unteren Treibernagel kann wahlweise ein Rastfedermittel und einen Betätigungslappen aufweisendes Aufsetzteil oder ein Blockiermittel aufweisendes Aufsetzteil angeordnet sein. Dies ermöglicht es, den unteren Treibernagel für alle Anwendungsbereiche gleich auszubilden und für verschiedene Anwendungen durch ein entsprechendes Aufsetzteil zu modifizieren.The profile advantageously has latching means, e.g. a groove or a rib on which can cooperate with appropriate locking means of the driver nail to the Lock the driver nail in the desired position. The profile of the Driver beam advantageously has a hollow profile part and two at the bottom Legs arranged on the hollow profile part. The upper driver nail can be in the Hollow profile part and the lower driver nail can be arranged in the legs. On such driver beam has a high stability with a relatively small mass, and Arrangement of the lower driver nail in the legs allows this to be done to manufacture two parts as described below. Advantageously points the driver nail has a detent spring, which with the locking means of the profile can cooperate. The driver nail can have an operating tab. A reduction in mass and better dimensional stability and dimensional stability reached when the driver nail spans at least part of its length, especially in the part that is movable in profile, is hollow. With great advantage the driver nail, e.g. the upper driver nail, with detent spring and / or Actuating flaps molded in one piece from plastic. This allows one achieve very high cost savings. On the lower driver nail you can choose one Latching spring means and a mounting part having an operating tab or a Blocking attachment piece can be arranged. This enables the design the lower driver nail for all areas of application and for different applications with an appropriate attachment part modify.

Der untere Treibernagel kann Mittel, z.B. zwei einander gegenüberliegende Ausnehmungen zur axialen Fixierung des Aufsetzteils aufweisen und das Aufsetzteil kann zwei federnde Schenkel zur Schnappbefestigung am Treibernagel besitzen. Dies ergibt eine besonders einfache Konstruktion. Die Rastfedermittel sind zweckmässigerweise durch an den Enden der Schenkel angeordnete Federn gebildet. Zwecks kostengünstiger Herstellung besteht das Aufsetzteil vorteilhaft aus Kunststoff.The lower driver nail can be agents e.g. two opposite each other Have recesses for axially fixing the attachment part and that Attachment part can have two resilient legs for snap fastening on Have a driver nail. This results in a particularly simple construction. The Latching spring means are expediently at the ends of the legs arranged springs formed. This is for the purpose of cost-effective production Attachment part advantageously made of plastic.

Vorteilhaft ist für den unteren Treibernagel ein von der Steuereinheit der Schiffchenstickmaschine steuerbares Betätigungselement, z.B. ein pneumatischer Zylinder, vorgesehen, um das Schiffchen bei Bedarf stillzulegen oder wieder zu aktivieren. Eine Schiffchenstillegung ist beispielsweise bei einem Farb- oder Rapportwechsel erwünscht, um eine Abscheuerung des Schiffchenfadens zu verhindern. Vorteilhaft sind die Betätigungselemente in einem Profil angeordnet, das beispielsweise aus einer Aluminiumlegierung besteht. Dies ermöglicht eine einfache und billige Konstruktion. Mit Vorteil weist das Profil eine Rippe aus, die als Drehachse für die Winkelhebel dient, wobei jeder Winkelhebel einen ersten Arm aufweist, der mit dem Betätigungselement gekuppelt ist, und einen zweiten Arm, der mit dem unteren Treibernagel kuppelbar ist. Der Winkelhebel kann als Kunststoffteil gefertigt werden und lässt sich auf die Rippe aufschnappen.Is advantageous for the lower driver nail from the control unit Shuttle embroidery machine controllable actuator, e.g. on pneumatic cylinder, provided to decommission the boat if necessary or reactivate. A ship's decommissioning is for example with one Color or repeat changes are desired to prevent abrasion of the To prevent shuttle thread. The actuators are advantageous in a profile arranged, for example, from an aluminum alloy consists. This enables a simple and cheap construction. Advantageously points the profile is a rib, which serves as the axis of rotation for the angle lever, wherein each angle lever has a first arm which is connected to the actuating element is coupled, and a second arm that connects to the lower driver nail can be coupled. The angle lever can be manufactured as a plastic part and leaves snap on the rib.

Bei dem in den Figuren 3 und 4 gezeigten ersten Ausführungsbeispiel der Erfindung besteht der Treiberbalken 11 der Treiberbalkeneinheit 10 aus einem Profil, beispielsweise einem gezogenen Profil aus einer Aluminiumlegierung. Für jede Stickstelle ist ein unterer Treibernagel 13 und ein oberer Treibernagel 15 vorgesehen. Um die oberen Treibernägel 15 aufzunehmen, sind im Abstand des sogenannten Rapports Bohrungen 31 vorgesehen. Unterhalb einer Bohrung 31 befindet sich jeweils eine weitere Bohrung 33 für die Rastfeder 35 des oberen Treibernagels 15. In entsprechenderweise sind auch Bohrungen 37 für die unteren Treibernägel 13 vorgesehen. Rastmittel, z.B. in Form einer Rippe 39, dienen der Arretierung der oberen Treibernägel 15 in der eingeschobenen Stellung. Rastmittel 40,41, z.B. in Form einer Rille, sind für die unteren Treibernägel 13 vorgesehen. In the first exemplary embodiment shown in FIGS According to the invention, the driver bar 11 of the driver bar unit 10 consists of a Profile, for example a drawn profile made of an aluminum alloy. For each embroidery site is a lower driver nail 13 and an upper driver nail 15 intended. To accommodate the upper driver nails 15 are at a distance so-called repeat holes 31 are provided. Below a bore 31 there is a further hole 33 for the detent spring 35 of the upper one Driver nail 15. In a corresponding manner are also holes 37 for the lower driver nails 13 provided. Locking means, e.g. in the form of a rib 39, serve to lock the upper driver nails 15 in the inserted Position. Locking means 40, 41, e.g. in the form of a groove, are for the lower ones Driver nails 13 provided.

Das Profil 11 besteht im wesentlichen aus einem Hohlprofilteil 43, von welchem sich zwei Schenkel 45 nach unten erstrecken. Die Vorsprünge 47,48 dienen der Führung von Befestigungsmitteln 51 zur Befestigung des Treiberbalkens am Treiberbalkenantrieb 53 (Fig. 5). Oben am Treiberbalken befindet sich eine Führung 55 für einen Schlitten, mit welchem die oberen Treibernägel 15 verschoben werden können, wie dies beispielsweise durch die GB-1,063,070 beschrieben wird.The profile 11 consists essentially of a hollow profile part 43, of which two legs 45 extend downward. The projections 47,48 serve the Guide of fasteners 51 for fastening the driver beam on Driver beam drive 53 (Fig. 5). There is one at the top of the driver bar Guide 55 for a carriage with which the upper driver nails 15 can be moved, such as by GB-1,063,070 is described.

Zur Verschiebung von Hand oder mittels eines Schlittens besitzen die oberen Treibernägel 15 einen Betätigungslappen 57. Um das Gewicht möglichst gering zu halten, sind die Treibernägel 13,15 mit einem Hohlraum 59 versehen, der sich über die Länge des im Profil 11 beweglichen Teils erstreckt. Der obere Treibernagel 15 mit Rastfeder 35 und Betätigungslappen 57 ist einstückig aus Kunststoff geformt. Dies erweist sich als besonders kostengünstig und bringt gegenüber Treibernägeln aus Metall eine Massereduktion. Es ist aber auch eine Fertigung der Treibernägel aus anderen Materialien als Kunststoff, z.B. Metall, denkbar. Gegebenenfalls wäre auch eine Fertigung teilweise aus Metall und teilweise aus Kunststoff denkbar.To move by hand or by means of a slide, the upper ones have Driver nails 15 an operating tab 57. To keep the weight as low as possible to hold, the driver nails 13, 15 are provided with a cavity 59, which is extends over the length of the part movable in profile 11. The upper Driver nail 15 with detent spring 35 and actuating tab 57 is made in one piece Molded plastic. This proves to be particularly inexpensive and brings a reduction in mass compared to metal driver nails. But it is also one Manufacture of driver nails from materials other than plastic, e.g. Metal, conceivable. If necessary, production would also be partially made of metal and partly made of plastic.

Der untere Treibernagel 13 könnte gleich oder ähnlich wie der obere Treibernagel ausgebildet werden, sofern dies die Platzverhältnisse erlauben. Beim gezeigten Ausführungsbeispiel besteht der untere Treibernagel 13 aus einem stiftförmigen Teil 13, der auf zwei einander gegenüberliegenden Seiten Aussparungen 61 aufweist. Nach dem Einsetzen des Treibernagels 13 in den Treiberbalken 11 kann das Aufsetzteil 63 im Bereich 61 aufgesetzt werden, wobei es in die Rille 41 des Profils 11 eingreift und den Treibernagel 13 axial fixiert (Fig. 4). Das Aufsetzteil 63 besitzt zwei federnde Schenkel 65 zur Schnappbefestigung am Treibernagel 13.The lower driver nail 13 could be the same as or similar to the upper driver nail be trained if space permits. In the shown In the exemplary embodiment, the lower driver nail 13 consists of a pin-shaped one Part 13, the recesses 61 on two opposite sides having. After inserting the driver nail 13 into the driver bar 11 can the attachment part 63 be placed in the area 61, wherein it in the groove 41 of the profile 11 engages and axially fixes the driver nail 13 (FIG. 4). The Attachment 63 has two resilient legs 65 for snap fastening on Driver nail 13.

Die Treiberbalkeneinheit 10' gemäss dem zweiten Ausführungsbeispiel nach Figur 6 unterscheidet sich von jener gemäss Figur 3 und 4 dadurch, dass der untere Treibernagel 13 im Treiberbalken 11 zur Schiffchenstillegung verschiebbar ist. Dies wird dadurch erreicht, dass anstelle des in Figur 3 gezeigten Aufsetzteils 63 das in Figur 5 gezeigte Aufsetzteil 67 auf den unteren Treibernagel 13 aufgesetzt wird. Das Aufsetzteil 67 besitzt federnde Schenkel 65', an deren Enden einstückig Federn 69 ausgebildet sind. Der mit einem solchen Aufsetzteil 67 ausgerüstete untere Treibernagel 13 kann daher im Treiberbalken 11 verschoben werden, wobei die Federn 69 in den Rillen 40 und 41 einrasten können, um den Treibernagel 13 in den entsprechenden Raststellungen zu halten. Der Verschiebung des Treibernagels 13 dient der Betätigungslappen 71.The driver bar unit 10 'according to the second embodiment according to Figure 6 differs from that of Figures 3 and 4 in that the lower driver nail 13 displaceable in the driver beam 11 for decommissioning is. This is achieved in that instead of the attachment part shown in FIG. 3 63 the attachment part 67 shown in FIG. 5 onto the lower driver nail 13 is put on. The attachment part 67 has resilient legs 65 ', on the other Ends 69 are integrally formed springs. The one with such an attachment 67 equipped lower driver nail 13 can therefore in the driver beam 11 are displaced, the springs 69 engaging in the grooves 40 and 41 can to the driver nail 13 in the corresponding locking positions hold. The actuation tab 71 serves to shift the driver nail 13.

Wenn bei einem Rapportwechsel oder Farbwechsel der untere Treibernagel 13 gezogen wird, kann das Schiffchen in der Schiffchenbahn 72 nach unten rutschen, so dass es von der Treiberbalkeneinheit 10' nicht mehr hin- und herbewegt wird. Wird der untere Treibernagel 13 wieder eingeschoben, so wird das Schiffchen wieder angehoben, so dass es zwischen den oberen und den unteren Treibernagel zu liegen kommt. Einzelheiten über diese Art von Schiffchenstillegung finden sich in der CH 677 805.If the lower driver nail 13 is pulled, the shuttle in shuttle shuttle 72 can go down slip so that it no longer back and forth from the driver beam unit 10 ' is moved. If the lower driver nail 13 is inserted again, then the boat is raised again, so that it is between the top and the lower driver nail comes to rest. Details of this type of Ship decommissioning can be found in CH 677 805.

Wie Figur 6 zeigt, ist jeweils für den unteren Treibernagel 13 ein von der Steuereinheit der Schiffchenstickmaschine steuerbares Betätigungselement 73, z.B. ein pneumatischer Zylinder, vorgesehen. Dieser Zylinder 73 ist in einem Profil 75, z.B. aus einer Aluminiumlegierung, angeordnet. Dieses Profil weist eine Rippe 77 auf, die als Drehachse für einen Winkelhebel 79 dient. Dieser besitzt einen ersten Arm 81, welcher mit dem Kolben 83 des Zylinders 73 gekuppelt ist. Der zweite Arm 85 kann auf der einen oder der anderen Seite am Lappen 71 des unteren Treibernagels 13 angreifen, um das Schiffchen stillzulegen, bzw. wieder zu aktivieren.As FIG. 6 shows, one of the two is for the lower driver nail 13 Control unit of the shuttle embroidery machine controllable actuating element 73, e.g. a pneumatic cylinder is provided. This cylinder 73 is in one Profile 75, e.g. made of an aluminum alloy. This profile has one Rib 77, which serves as the axis of rotation for an angle lever 79. This owns a first arm 81 which is coupled to the piston 83 of the cylinder 73. The second arm 85 can on one side or the other on the tab 71 of the Attack lower driver nail 13 to shut down the boat, or again to activate.

Beim Testen von Stickmaschinen mit vorangehend beschriebenen Treiberbalkeneinheiten hat sich gezeigt, dass mit sehr hohen Geschwindigkeiten gefahren werden kann, ohne dass starke Vibrationen entstehen. Vorteilhaft ist auch, dass Kosten für die Treiberbalkeneinheiten auf einen Bruchteil der Kosten für eine herkömmliche Treiberbalkeneinheit gesenkt werden konnten. When testing embroidery machines with those described above Driver beam units have been shown to operate at very high speeds can be driven without strong vibrations. It is advantageous also that cost of the driver beam units at a fraction of the cost could be reduced for a conventional driver beam unit.

Zusammenfassend kann folgendes festgehalten werden:In summary, the following can be stated:

Die Schiffchenstickmaschine weist eine Treiberbalkeneinheit 10 auf, deren Treiberbalken 11 aus einem gezogenen Profil, z.B. aus einer Aluminiumlegierung, besteht. Für jede Stickstelle ist ein unterer Treibernagel 13 und ein oberer Treibernagel 15 vorgesehen, die in Bohrungen 37,31 eingesetzt sind. Der obere Treibernagel 15 ist samt Rastfeder 35 und Betätigungslappen 57 einstückig z.B. aus Kunststoff geformt. In der eingeschobenen Stellung des Treibernagels 15 kann die Rastfeder 35 an einer Rille oder einer Rippe 39 einrasten. Auf dem unteren Treibernagel 13 kann nach dem Einsetzen in den Treiberbalken 11 wahlweise ein Aufsetzteil 63 oder ein Aufsetzteil 67 aufgeschnappt werden. Mit dem Aufsetzteil 63, das in die Rille 41 eingreift, wird der Treibernagel 13 blockiert. Mit dem Aufsetzteil 67 bleibt der Treibernagel 13 verschiebbar, kann aber mit den Federn 69, die in Rillen 40,41 eingreifen können, in zwei verschiedenen Stellungen gesichert werden. Ein von der Stickmaschine steuerbares Betätigungselement 73 dient der Betätigung des unteren Treibernagels 13. Der Treiberbalken ist sehr kostengünstig in der Herstellung und besitzt eine geringe Masse, die hohe Stickgeschwindigkeiten erlaubt.The shuttle embroidery machine has a driver bar unit 10, the Driver beam 11 from a drawn profile, e.g. made of an aluminum alloy, consists. For each embroidery site there is a lower driver nail 13 and an upper one Driver nail 15 provided, which are inserted into holes 37,31. The upper Driver nail 15 together with detent spring 35 and actuating tab 57 is in one piece, e.g. molded from plastic. In the retracted position of the driver nail 15 can engage the detent spring 35 on a groove or a rib 39. On the lower driver nail 13 can be inserted into the driver bar 11th either a mounting part 63 or a mounting part 67 can be snapped on. With the attachment part 63, which engages in the groove 41, becomes the driver nail 13 blocked. With the attachment part 67, the driver nail 13 remains displaceable but with the springs 69, which can engage in grooves 40, 41, in two different positions are secured. One from the embroidery machine controllable actuating element 73 serves to actuate the lower one Driver nail 13. The driver beam is very inexpensive to manufacture and has a low mass, which allows high embroidery speeds.
