Definitions
- the invention relates to a sequin feed device for embroidery and / or sewing machines, one slider Sequins of an at least partially guided laterally Sequin tape gradually fed to a tapping point, and a drive periodically to a slide Tapping point moved to and from the tapping point, wherein the slide has a driver that the Movement of the slide in the direction of the tapping point in a sequin opening of a sequin engages.
- Sequins are made as a coherent, on a spool wrapped sequin ribbon in semi-finished die-cut Form of the facility fed.
- the sequin is mostly punched a circular opening into which the embroidering needle dips to after piercing the Embroider the sequins with the embroidery or sewing used embroidery thread or threads on the embroidery fasten.
- the needle is immersed in the embroidery is at the time over the cutting edge part of the sequin ribbon protruding freely from the knife, ie. the sequin to be sewn on one by the pre-punched outer contour of the sequin tape Part separated by a knife, causing the Sequin contour is completed.
- the openings punched in the sequins will not used only as a piercing hole for the needle, but also serve to transmit the feed movement, which in the known devices by a so-called Wart wheel or as from the German utility model G 9209764 known by means of a on a slide molded driver in partial steps of the stitching point fed.
- Sequin feeders which hold the sequin belt by means of a wart wheel, have the Disadvantage that the manufacturing tolerances of Sequin ribbon and the driving pins of the wart wheel those engaging in the openings of the sequins Driver pins have a certain game, which is what Do not move the sequin tape in the feed direction can. This effect is reinforced by the fact that mostly 3-4 driving pins at the same time in a row intervene arranged sequins.
- the through the game possible shifting of the sequin ribbon compared to the The point of stitching means that even if the others Transport involved drive and locking elements without play work through the prepunched outer contour of the Sequin tape predetermined separation point by the size of the Game can be missed, leading to a failure desired jagged outer contour, which leads to a represents a significant reduction in the quality of the embroidery, because this abnormal sequin shape even with small ones Deviations can be seen with the naked eye.
- the sequin feeder known from G 9209764 is by using only one Driver always ensures that the quality of the Embroidery only from the manufacturing tolerances of the Sequin ribbon depends.
- the driver is on one Shaped slide, the spring on the sequin band is present.
- the slider is a two-armed lever executed, which is pivotally mounted on a drive lever is, wherein one arm has the driver and the other arm connected to the drive lever via a spring is. So that the driver on the one hand during the transport stroke form-fitting on the repeating form elements of the Sequin tape can attack and on the other hand Can move idle stroke without taking the sequin belt with it, the driver has on the front in the feed direction a stop surface almost perpendicular to the plane and an oblique sliding surface on the back. A an additional braking element presses the sequin band against a pressure plate or knife plate, the braking element the sequin ribbon leads to the side.
- a disadvantage of the sequin feeder after G 9209764 is that relatively many parts for the drive of the slide and for the braking element are necessary.
- the object of the invention is therefore to provide a sequin feed device provide that from a few parts there is and still an exact feeding of the sequin ribbon guaranteed.
- the Slider at least partially elastic, especially one Leaf spring is, and the sequin ribbon against a pressure plate pressurized. Because the slider is elastic, no additional spring elements needed. The pressure force is advantageously from the slide self-generated. Due to the flexibility of the slide also manufacturing tolerances regarding the height of the sequin ribbon balanced without affecting the feed.
- part of the Leaf spring angled in the direction of the sequin ribbon is a tab-shaped, in particular triangular part, which with its one, the Side facing away from the tapping point, formed on the slide is. It is particularly advantageous if the angled Part is formed on the end of the slide. However, it is also conceivable, the tab half from the leaf spring punch out and then bend. The angled part thus forms a hook, the Side facing away from the hook opening forms a sliding surface. If the slide in the direction of the tapping point of the Drive moves, so the driver is in a sequin opening pushed in and transported through the Take the sequin ribbon by one on the drive adjustable distance in the direction of the tapping point.
- the leaf spring is preferably at one end attached to a lever, the lever by means of a Drive is rotatable about an axis.
- the leaf spring pressurized with its other end the sequin ribbon, the driver being arranged at the other end. If the lever is turned, it becomes the driver end of the leaf spring either from the Tapping point pulled away or towards the tapping point pushed.
- the leaf spring is here with all possible Twisted positions of the lever so tensioned that they Sequin tape with sufficient pressure against the Pressure or knife plate presses.
- the deflection of the Lever for the feed and retraction movement of the Driver is dependent on the length of the lever and the deflection of the leaf spring. The greater the distance between the Attachment point of the leaf spring from the axis of rotation of the Lever, the smaller the required twist angle of the lever with the same sequin diameter.
- the pivoting movement is achieved by means of a limiting element advantageously limited in both directions, whereby low demands on the drive or the Manufacturing tolerances of those used for the drive Components must be placed.
- the limiting element is a U-shaped part, the two legs of the U-shaped Partly a limit for the pivoting of the Form lever.
- To the legs are advantageous Adjusting screws, each in a thread of the Legs are screwed.
- the Swivel movement or the maximum swivel angle in the respective direction can be specified precisely.
- the braking element is a spring, in particular a leaf or Coil spring is, with the spring at one end the sequin feeder is fixed and with the other end of the sequin ribbon against a pressure plate presses in such a way that the sequin band only at Overcoming the adhesive and / or generated by means of the braking element Frictional force in the direction of the tapping point can be transported.
- FIG. 1 shows a sequin feeder 1, the a sequin ribbon 2 from a roll, not shown is fed.
- the sequin band 2 is by a Slot 11 inserted into the sequin feeder, the slot 11 from the fastener 13 of the braking element 10 and the pressure plate 8 are formed becomes.
- the height of the slot 11 is larger than the largest Thickness of the sequins used 3.
- a leaf spring 10 is at the Fastening device 13 by means of a screw 13a attached.
- the leaf spring 10 is by means of the adjusting screw 13b, which is also used for Attachment of the fastening device 13 to the Base plate 23 of the sequin feeder 1 is used, bent such that the sequin band 2 between the Leaf spring 10 and the pressure plate 8 with a certain Contact pressure is kept.
- the leaf spring 10 which as Brake element is used, the sequin band 2 against Pressure plate 8 pressed and is up to the tapping point 24 flat on this on.
- the sequin band 2 is fastened by means of the guide rails 5 guided laterally, the guide rails 5 by means of Screws are releasably attached to the pressure plate 8, so that the width of the formed by the guide rails 5 Guide channel to the diameter of the embroidery sewn on or to be sewn on sequins 3 adapted can be.
- the sequin band 2 is through the curved leaf spring 6 pressed against the pressure plate 8, the sequin band 2 only from the guide channel in direction V can slide out.
- the leaf spring 6 in the untensioned state except for the down, ie. in the direction of the pressure plate 8 or of the sequin ribbon 2 bent tip 6a flat and an opening at one end 7 through which a retaining screw reaches through and the leaf spring 6 at the bottom End of the lever 14 holds.
- the lever 14 is on the of the Not shown drive driven shaft 15th attached, whereby the leaf spring when the shaft 15 rotates 6 either in the V direction, ie. to the tap point 24 or is moved away from it.
- Both swiveling movements are in the directions V, R of the lever 14 through the legs 19, 21 of the U-shaped limiting part, which on the base plate 23 of the sequin feed device 1 is fixed, limited.
- the Legs 19.21 fastening screws 20.22 by means of Threads that are more or less far into the Threads can be screwed in, this from the Dimensions of the sequins 3 to be embroidered depend is.
- the leaf spring 6 is always in all pivoting positions bent, whereby the sequin band 2 is constantly pressurized becomes. If the lever 14, as can be seen in FIG. 2, towards R, ie. away from the tapping point 24 is pivoted, so that at the lower end of the lever 14th attached leaf spring 6 moved away from the tapping point 24. As can be seen from FIGS. 3a and 3b, this is End 6a of the leaf spring slightly in the direction of the sequin band 2 angled, making one to the sequin ribbon 2 slightly inclined and pointing sliding surface 6b arises, through which the tip 6a of the leaf spring 6 during pivoting movement V of the lever 14 tries the sequin tape 2nd to move away from the tapping point 24.
- the lever 14 If the lever 14 is pivoted in the direction V, it slides the angled tip 6a of the leaf spring 6 in the provided opening 4 of the sequin 3. The leaf spring 6 does not slide from this point on or twist angle more about the sequin ribbon 2, but pushes that Sequin band 2 through the barb effect in direction V to the tapping point 24. As soon as the complete pivoting movement is performed by the lever 14, ie. the lever with its surface 18a towards the end of the adjusting screw 22 pushes, the needle, not shown, pierces through the in the tapping point 24 located sequin 3 'and holds this in position. Then the Sequin 3 'to be sewn on by means of a knife 9 Sequin ribbon 2 separated at 3b.

Description
Die Erfindung betrifft eine Paillettenzuführeinrichtung für Stick- und/oder Nähmaschinen, wobei ein Schieber Pailletten eines zumindest teilweise seitlich geführten Paillettenbandes schrittweise einer Anstichstelle zuführt, und ein Antrieb den Schieber periodisch zu einer Anstichstelle hin und von der Anstichstelle weg bewegt, wobei der Schieber einen Mitnehmer hat, der bei der Bewegung des Schiebers in Richtung der Anstichstelle in eine Paillettenöffnung einer Paillette eingreift.The invention relates to a sequin feed device for embroidery and / or sewing machines, one slider Sequins of an at least partially guided laterally Sequin tape gradually fed to a tapping point, and a drive periodically to a slide Tapping point moved to and from the tapping point, wherein the slide has a driver that the Movement of the slide in the direction of the tapping point in a sequin opening of a sequin engages.
Pailletten werden als zusammenhängendes, auf einer Spule aufgewickeltes Paillettenband in halbfertig gestanzter Form der Einrichtung zugeführt. In die Paillette ist meist eine kreisförmige Öffnung eingestanzt, in welche die stickende Nadel eintaucht, um nach dem Durchstoßen des Stickgutes die Paillette mit dem beim Sticken bzw. Nähen verwendeten Stickfaden bzw. -fäden am Stickgut zu befestigen. Nachdem die Nadel in das Stickgut eingetaucht ist, wird der zu diesem Zeitpunkt über die Schneidkante des Messers frei vorstehende Teil des Paillettenbandes, dh. die anzustickende Paillette, an einer durch die vorgestanzte Außenkontur des Paillettenbandes vorgegebenen Stelle durch ein Messer abgetrennt, wodurch die Paillettenkontur fertiggestellt wird.Sequins are made as a coherent, on a spool wrapped sequin ribbon in semi-finished die-cut Form of the facility fed. In the sequin is mostly punched a circular opening into which the embroidering needle dips to after piercing the Embroider the sequins with the embroidery or sewing used embroidery thread or threads on the embroidery fasten. After the needle is immersed in the embroidery is at the time over the cutting edge part of the sequin ribbon protruding freely from the knife, ie. the sequin to be sewn on one by the pre-punched outer contour of the sequin tape Part separated by a knife, causing the Sequin contour is completed.
Die in den Pailletten eingestanzten Öffnungen werden nicht nur als Durchstoßöffnung für die Nadel benutzt, sondern dienen auch der Übertragung der Vorschubbewegung, welche bei den bekannten Einrichtungen durch ein sogenanntes Warzenrad oder wie aus dem deutschen Gebrauchstmuster G 9209764 bekannt mittels eines an einem Schieber angeformten Mitnehmers in Teilschritten der Anstickstelle zugeführt.The openings punched in the sequins will not used only as a piercing hole for the needle, but also serve to transmit the feed movement, which in the known devices by a so-called Wart wheel or as from the German utility model G 9209764 known by means of a on a slide molded driver in partial steps of the stitching point fed.
Paillettenzuführeinrichtungen, welche das Paillettenband mittels eines Warzenrades transportieren, haben den Nachteil, daß durch die Fertigungstoleranzen des Paillettenbandes und der Mitnehmerstifte des Warzenrades die in die Öffnungen der Pailletten eingreifenden Mitnehmerstifte ein gewisses Spiel haben, wodurch sich das Paillettenband in Vorschubrichtung unzulässig verschieben kann. Dieser Effekt wird noch dadurch verstärkt, daß meist 3-4 Mitnehmerstifte gleichzeitig in hintereinander angeordnete Pailletten eingreifen. Die durch das Spiel mögliche Verschiebung des Paillettenbandes gegenüber der Anstickstelle führt dazu, daß, selbst wenn die anderen am Transport beteiligten Antriebs- und Rastelemente spielfrei arbeiten, die durch die vorgestanzte Außenkontur des Paillettenbandes vorgegebene Trennstelle um die Größe des Spiels verfehlt werden kann, was zu einer nicht gewünschten gezackten Außenkontur führt, welche eine erhebliche Qualitätsverminderung der Stickerei darstellt, da diese abnormale Paillettenform auch schon bei kleinen Abweichungen mit bloßem Auge erkennbar ist.Sequin feeders which hold the sequin belt by means of a wart wheel, have the Disadvantage that the manufacturing tolerances of Sequin ribbon and the driving pins of the wart wheel those engaging in the openings of the sequins Driver pins have a certain game, which is what Do not move the sequin tape in the feed direction can. This effect is reinforced by the fact that mostly 3-4 driving pins at the same time in a row intervene arranged sequins. The through the game possible shifting of the sequin ribbon compared to the The point of stitching means that even if the others Transport involved drive and locking elements without play work through the prepunched outer contour of the Sequin tape predetermined separation point by the size of the Game can be missed, leading to a failure desired jagged outer contour, which leads to a represents a significant reduction in the quality of the embroidery, because this abnormal sequin shape even with small ones Deviations can be seen with the naked eye.
Bei der aus dem G 9209764 bekannten Paillettenzuführeinrichtung ist durch die Verwendung lediglich eines Mitnehmers stets gewährleistet, daß die Qualität der Stickerei nur allein von den Fertigungstoleranzen des Paillettenbandes abhängt. Der Mitnehmer ist dabei an einem Schieber angeformt, der unter Federwirkung am Paillettenband anliegt. Der Schieber ist dabei als zweiarmiger Hebel ausgeführt, der schwenkbar an einem Antriebshebel gelagert ist, wobei der eine Arm den Mitnehmer aufweist und der andere Arm über eine Feder mit dem Antriebshebel verbunden ist. Damit der Mitnehmer einerseits beim Transporthub formschlüssig an den sich wiederholenden Formelementen des Pailletenbandes angreifen kann und andererseits sich beim Leerhub ohne Mitnahme des Paillettenbandes bewegen kann, besitzt der Mitnehmer auf der Vorderseite in Vorschubrichtung eine zur Ebene annähernd senkrechte Anschlagfläche und rückseitig eine schräge Gleitfläche. Ein zusätzliches Bremselement drückt das Paillettenband gegen eine Andruck- bzw. Messerplatte, wobei das Bremselement das Paillettenband seitlich führt.In the sequin feeder known from G 9209764 is by using only one Driver always ensures that the quality of the Embroidery only from the manufacturing tolerances of the Sequin ribbon depends. The driver is on one Shaped slide, the spring on the sequin band is present. The slider is a two-armed lever executed, which is pivotally mounted on a drive lever is, wherein one arm has the driver and the other arm connected to the drive lever via a spring is. So that the driver on the one hand during the transport stroke form-fitting on the repeating form elements of the Sequin tape can attack and on the other hand Can move idle stroke without taking the sequin belt with it, the driver has on the front in the feed direction a stop surface almost perpendicular to the plane and an oblique sliding surface on the back. A an additional braking element presses the sequin band against a pressure plate or knife plate, the braking element the sequin ribbon leads to the side.
Nachteilig bei der Paillettenzuführeinrichtung nach dem G 9209764 ist, daß verhältnismäßig viele Teile für den Antrieb des Schiebers und für das Bremselement notwendig sind. A disadvantage of the sequin feeder after G 9209764 is that relatively many parts for the drive of the slide and for the braking element are necessary.
Aufgabe der Erfindung ist es daher, eine Paillettenzuführeinrichtung bereitzustellen, die aus wenigen Teilen besteht und dennoch eine exakte Zuführung des Paillettenbandes gewährleistet.The object of the invention is therefore to provide a sequin feed device provide that from a few parts there is and still an exact feeding of the sequin ribbon guaranteed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schieber zumindest teilweise elastisch, insbesondere eine Blattfeder ist, und das Paillettenband gegen eine Andruckplatte druckbeaufschlagt. Dadurch daß der Schieber elastisch ist, werden keine zusätzlichen Federelemente benötigt. Die Andurckkraft wird vorteilsmäßig vom Schieber selbst erzeugt. Durch die Biegsamkeit des Schiebers werden zudem Fertigungstoleranzen bzgl. der Höhe des Paillettenbandes ohne Beeinträchtigung des Vorschubes ausgeglichen.This object is achieved in that the Slider at least partially elastic, especially one Leaf spring is, and the sequin ribbon against a pressure plate pressurized. Because the slider is elastic, no additional spring elements needed. The pressure force is advantageously from the slide self-generated. Due to the flexibility of the slide also manufacturing tolerances regarding the height of the sequin ribbon balanced without affecting the feed.
In einer bevorzugten Ausführungsform ist ein Teil der Blattfeder in Richtung des Paillettenbandes abgewinkelt, wobei das abgewinkelte Teil den Mitnehmer bildet. Der Mitnehmer ist dabei ein laschenförmiges, insbesondere dreieckförmiges Teil, welches mit seiner einen, der Anstichstelle abgewandten Seite, an dem Schieber angeformt ist. Besonders vorteilsmäßig ist es, wenn das abgewinkelte Teil am Ende des Schiebers angeformt ist. Es ist jedoch auch denkbar, die Lasche halb aus der Blattfeder auszustanzen und anschließend abzuwinkeln. Das abgewinkelte Teil bildet somit einen Haken, dessen der Hakenöffnung abgewandte Seite eine Gleitfläche bildet. Wird der Schieber in Richtung der Anstichstelle von dem Antrieb bewegt, so wird der Mitnehmer in eine Paillettenöffnung hineingedrückt und transportiert durch den Mitnahmehaken das Paillettenband um eine am Antrieb einstellbare Strecke in Richtung der Anstichstelle. Wird der Schieber von der Anstichstelle weg bewegt, so gleitet der Mitnehmer, bedingt durch die schräge Gleitfläche aus der Paillettenöffnung heraus. Der Schieber wird dabei mindestens um die Distanz eines Paillettendurchmessers von der Anstichstelle weg bewegt, damit stets gewährleistet ist, daß bei der nächsten Vorschubbewegung der Mitnehmer in die entsprechende Paillettenöffnung eingreifen kann.In a preferred embodiment, part of the Leaf spring angled in the direction of the sequin ribbon, the angled part forming the driver. Of the The driver is a tab-shaped, in particular triangular part, which with its one, the Side facing away from the tapping point, formed on the slide is. It is particularly advantageous if the angled Part is formed on the end of the slide. However, it is also conceivable, the tab half from the leaf spring punch out and then bend. The angled part thus forms a hook, the Side facing away from the hook opening forms a sliding surface. If the slide in the direction of the tapping point of the Drive moves, so the driver is in a sequin opening pushed in and transported through the Take the sequin ribbon by one on the drive adjustable distance in the direction of the tapping point. Becomes the slide moves away from the tapping point, so it slides the driver due to the inclined sliding surface the sequin opening. The slider will at least by the distance of a sequin diameter of the tapping point moved away, thus always guaranteed is that with the next feed movement the driver can engage in the corresponding sequin opening.
Bevorzugt wird die Blattfeder mit ihrem einen Ende an einem Hebel befestigt, wobei der Hebel mittels eines Antriebs um eine Achse verdrehbar ist. Die Blattfeder druckbeaufschlagt mit ihrem anderen Ende das Paillettenband, wobei am anderen Ende der Mitnehmer angeordnet ist. Wird der Hebel verdreht, so wird das den Mitnehmer aufweisende Ende der Blattfeder entweder von der Anstichstelle weggezogen oder hin zur Anstichstelle geschoben. Die Blattfeder ist hierbei bei allen möglichen Verdrehstellungen des Hebels derart gespannt, daß sie das Paillettenband mit einem ausreichenden Druck gegen die Andruck- bzw. Messerplatte drückt. Die Auslenkung des Hebels für die Vorschub- und Rückzugsbewegung des Mitnehmers ist dabei abhängig von der Länge des Hebels und der Durchbiegung der Blattfeder. Je größer der Abstand der Befestigungsstelle der Blattfeder von der Drehachse des Hebels ist, desto kleiner wird der notwendige Verdrehwinkel des Hebels bei gleichbleibendem Paillettendurchmesser. The leaf spring is preferably at one end attached to a lever, the lever by means of a Drive is rotatable about an axis. The leaf spring pressurized with its other end the sequin ribbon, the driver being arranged at the other end. If the lever is turned, it becomes the driver end of the leaf spring either from the Tapping point pulled away or towards the tapping point pushed. The leaf spring is here with all possible Twisted positions of the lever so tensioned that they Sequin tape with sufficient pressure against the Pressure or knife plate presses. The deflection of the Lever for the feed and retraction movement of the Driver is dependent on the length of the lever and the deflection of the leaf spring. The greater the distance between the Attachment point of the leaf spring from the axis of rotation of the Lever, the smaller the required twist angle of the lever with the same sequin diameter.
Mittels eines Begrenzungselementes wird die Verschwenkbewegung vorteilsmäßig in beide Richtungen begrenzt, wodurch geringe Anforderungen an den Antrieb bzw. die Fertigungstoleranzen der für den Antrieb verwendeten Bauteile gestellt werden müssen. In einer besonders einfachen Ausführungsform ist das Begrenzungselement ein U-förmiges Teil, wobei die beiden Schenkel des U-förmigen Teils jeweils eine Begrenzung für die Verschwenkung des Hebels bilden. An den Schenkel sind dazu vorteilsmäßig Verstellschrauben, die jeweils in ein Gewinde des Schenkels einschraubbar sind. Je nach dem, wie weit die Verstellschraube in den Schenkel eingedreht ist, ist die Verschwenkbewegung bzw. der maximale Verschwenkwinkel in die jeweilige Richtung genauestens vorgebbar. Durch eine derartige Ausgestaltung kann auf Sensoren und damit verbunden, auf eine aufwendige Steuerung des Antriebs verzichtet werden. Sollen in ihrer Größe verschiedene Pailletten nacheinander mit der Stick- oder Nähmaschine an dem Stickgut angebracht werden, so genügt es, mittels der Verstellschrauben den jeweils zur Paillettengröße gehörigen maximalen Verschwenkwinkel des Hebels einzustellen.The pivoting movement is achieved by means of a limiting element advantageously limited in both directions, whereby low demands on the drive or the Manufacturing tolerances of those used for the drive Components must be placed. In one particularly simple embodiment, the limiting element is a U-shaped part, the two legs of the U-shaped Partly a limit for the pivoting of the Form lever. To the legs are advantageous Adjusting screws, each in a thread of the Legs are screwed. Depending on how far the Is screwed into the leg, is the Swivel movement or the maximum swivel angle in the respective direction can be specified precisely. By a Such design can be based on sensors and thus connected to a complex control of the drive to be dispensed with. Should be different in size Sequins in sequence with the embroidery or sewing machine attached to the embroidery, it is sufficient to use the Adjusting screws to the sequin size proper maximum pivoting angle of the lever adjust.
Eine besonders einfache Ausführungsform ergibt sich, wenn das Bremselement eine Feder, insbesondere eine Blatt- oder Spiralfeder ist, wobei die Feder mit ihrem einen Ende an der Paillettenzuführeinrichtung fest gelagert ist und mit ihrem anderem Ende das Paillettenband gegen eine Andruckplatte drückt, derart, daß das Paillettenband nur bei Überwindung der mittels des Bremselementes erzeugten Haft- und/oder Reibungskraft in Richtung der Anstichstelle transportiert werden kann. A particularly simple embodiment results when the braking element is a spring, in particular a leaf or Coil spring is, with the spring at one end the sequin feeder is fixed and with the other end of the sequin ribbon against a pressure plate presses in such a way that the sequin band only at Overcoming the adhesive and / or generated by means of the braking element Frictional force in the direction of the tapping point can be transported.

Die Figur 1 zeigt eine Paillettenzuführeinrichtung 1, der
ein Paillettenband 2 von einer nicht dargestellten Rolle
zugeführt wird. Das Paillettenband 2 wird durch einen
Schlitz 11 in die Paillettenzuführeinrichtung eingeführt,
wobei der Schlitz 11 von der Befestigungseinrichtung 13
des Bremselementes 10 und der Andruckplatte 8 gebildet
wird. Die Höhe des Schlitzes 11 ist größer als die größte
Dicke der Verwendung findenden Pailletten 3. An der
Befestigungseinrichtung 13 ist eine Blattfeder 10 mittels
einer Schraube 13a befestigt. Die Blattfeder 10 wird
mittels der Einstellschraube 13b, welche zugleich zur
Befestigung der Befestigungseinrichtung 13 an der
Basisplatte 23 der Paillettenzuführeinrichtung 1 dient,
derart gebogen, daß das Paillettenband 2 zwischen der
Blattfeder 10 und der Andruckplatte 8 mit einem bestimmten
Anpreßdruck gehalten ist. Durch die Blattfeder 10, die als
Bremselement dient, wird das Paillettenband 2 gegen die
Andruckplatte 8 gedrückt und liegt bis zur Anstichstelle
24 flach auf dieser auf.Figure 1 shows a
Mittels der Führungsschienen 5 wird das Paillettenband 2
seitlich geführt, wobei die Führungsschienen 5 mittels
Schrauben an der Andruckplatte 8 lösbar befestigt sind, so
daß die Breite des durch die Führungsschienen 5 gebildeten
Führungskanals jeweils an den Durchmesser der am Stickgut
anzunähenden bzw. anzustickenden Pailletten 3 angepaßt
werden kann.The
Das Paillettenband 2 ist durch die gebogene Blattfeder 6
gegen die Andruckplatte 8 gedrückt, wobei das Paillettenband
2 lediglich aus dem Führungskanal in Richtung V
herausgleiten kann. Wie aus den Figuren 3a und 3b ersichtlich,
ist die Blattfeder 6 im ungespannten Zustand bis auf
die nach unten, dh. in Richtung der Andruckplatte 8 bzw.
des Paillettenbandes 2 abgebogenen Spitze 6a flach und hat
eine Öffnung an ihrem einen Ende 7, durch die eine Halteschraube
hindurchgreift und die Blattfeder 6 am unteren
Ende des Hebels 14 hält. Der Hebel 14 ist auf der von dem
nicht dargestellten Antrieb angetriebenen Welle 15
befestigt, wodurch bei Drehung der Welle 15 die Blattfeder
6 entweder in Richtung V, dh. zur Anstichstelle 24 hin-
oder von dieser weg bewegt wird. Beide Verschwenkbewegungen
sind in den Richtungen V,R des Hebels 14 durch
die Schenkel 19,21 des U-förmigen Begrenzungsteils,
welches an der Basisplatte 23 der Paillettenzuführ
einrichtung 1 befestigt ist, begrenzt. Hierzu sind an den
Schenkeln 19,21 Befesigungsschrauben 20,22 mittels
Gewinden gehalten, welche mehr oder weniger weit in die
Gewinde eingeschraubt werden können, wobei dies von den
Abmessungen der zu verstickenden Pailletten 3 abhängig
ist.The
Die Blattfeder 6 ist bei allen Verschwenkpositionen stets
gebogen, wodurch das Paillettenband 2 ständig druckbeaufschlagt
wird. Wird der Hebel 14, wie aus Figur 2 ersichtlich,
in Richtung R, dh. weg von der Anstichstelle 24
verschwenkt, so wird die an dem unteren Ende des Hebels 14
befestigte Blattfeder 6 von der Anstichstelle 24 wegbewegt.
Wie aus den Figuren 3a und 3b ersichtlich, ist das
Ende 6a der Blattfeder leicht in Richtung des Paillettenbandes

leicht geneigte und zeigende Gleitfläche 6b entsteht,
durch die die Spitze 6a der Blattfeder 6 bei Verschwenkbewegung
V des Hebels 14 versucht, das Paillettenband 2
von der Anstichstelle 24 wegzubewegen. Dadurch jedoch, daß
die Blattfeder 10 das Paillettenband 2 ebenfalls gegen die
Andruck- bzw. Messerplatte 8 druckbeaufschlagt, und zwar
mit eine größeren Andruckkraft, wird die Blattfeder 6 nach
oben hin derart verbogen, daß die Spitze 6a der Blattfeder
6 aus der Öffnung 4 der Paillette 3 herausgleitet. Das
Paillettenband 2 ist somit bei der Verschwenkbewegung R

Wird der Hebel 14 in Richtung V verschwenkt, so gleitet
die abgewinkelte Spitze 6a der Blattfeder 6 in die
vorgesehene Öffnung 4 der Paillette 3 ein. Die Blattfeder
6 gleitet ab diesem Zeitpunkt bzw. Verdrehungswinkel nicht
mehr über das Paillettenband 2, sondern schiebt das
Paillettenband 2 durch die Widerhakenwirkung in Richtung V
zur Anstichstelle 24. Sobald die vollständige Verschwenkbewegung
von dem Hebel 14 durchgeführt ist, dh. der Hebel
mit seiner Fläche 18a gegen das Ende der Einstellschraube
22 stößt, sticht die nicht dargestellte Nadel durch die in
der Anstichstelle 24 befindliche Paillette 3' und hält
diese in Position. Danach wird die anzustickende bzw.
anzunähende Paillette 3' mittels eines Messers 9 vom
Paillettenband 2 bei 3b abgetrennt.If the
