Abstract

Apparatus for transferring a fabric strip 12 from a deposit station 10 to a support base 16 includes a plate 24 having a stop ledge 28 abutting an end of the fabric strip 12. A bar 34 projects through an opening 30 in plate 24 to create a fold in the fabric strip 12. A thin plate 66 retracts against a ledge 52 to grasp the fabric strip 12. Then, the transfer clamp 14 is rotated into a position such that the plate 66 lies flush with the support base 16. The transfer clamp releases the folded fabric strip 12 in a position where it is then fed into the sewing machine 22 together with the fabric piece 18 when they are sewn together.

Description

Die Erfindung betrifft eine Vorrichtung zur Übertragung eines Stoffstreifens von einer Einlegestation auf eine Unterlage gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for transferring a strip of fabric from an insertion station to a base according to the preamble of claim 1.

Eine derartige Vorrichtung ist beispielsweise aus der DE-OS 26 56 720 bekannt. Bei der bekannten Vorrichtung, die zum Übertragen einer Patte aus der Einlegestation auf eine Stoffklammer dient, die ihrerseits das mit der Patte zu vernähende Stoffteil auf dem Nähmaschinentisch festhält, erfaßt die Übertragungsklammer einen über den Rand der Auflageplatte vorstehenden Randbereich des Stoffstreifens und zieht diesen in einer Schwenkbewegung unter einer mit der Stoffklammer verbundenen Pattenklammer hindurch, so daß der Stoffstreifen von der Pattenklammer auf der Stoffklammer festgehalten werden kann. Eine der eingangs genannten Vorrichtung ähnliche Vorrichtung zur Übertragung eines Paspelstreifens in eine Paspelstreifenfaltvorrichtung ist ferner aus der DE-OS 2123160 bekannt. Dabei ergreift die geradlinig verstellbare Übertragungsklammer einen über die Auflageplatte vorstehenden Randbereich des Paspelstreifens und legt diesen in die Faltvorrichtung für den Paspelstreifen ein.Such a device is known for example from DE-OS 26 56 720. In the known device, which is used to transfer a flap from the insertion station to a cloth clip, which in turn holds the piece of fabric to be sewn with the flap on the sewing machine table, the transfer clip detects an edge region of the strip of material projecting over the edge of the support plate and pulls it in one Swiveling movement under a flap clip connected to the cloth clip so that the strip of cloth can be held on the flap clip by the flap clip. A device similar to the device mentioned at the outset for transferring a piping strip into a piping strip folding device is also known from DE-OS 2123160. The rectilinearly adjustable transmission clamp grips an edge region of the piping strip projecting above the support plate and inserts it into the folding device for the piping strip.

In beiden Fällen wird der Stoffstreifen unverändert von der Einlegestation zur Unterlage hin übertragen. Es gibt nun Fälle, in denen der Stoffstreifen vor dem Auflegen auf die Unterlage, beispielsweise ein mit dem Stoffstreifen zu vernähendes Stoffteil, gefaltet werden muß. Beispielsweise wird bei Hosentaschen angestrebt, den den Taschenbesatz bildenden Stoffstreifen an seiner Naht stelle mit dem Taschenbeutel nicht nur zu umstechen, da der Träger der Hose an den Fäden dieser Naht leicht hängenbleibt und die Naht aufreißt. Vielmehr soll der Taschenbesatz in diesem Nahtbereich zunächst gefaltet und anschließend mit dem Taschenbeutel vernäht werden. Für diesen Vorgang muß die Näherin den den Taschenbesatz bildenden Stoffstreifen zunächst falten, den Stoffstreifen in gefaltetem Zustand auf den Taschenbeutel legen und beide Teile von Hand durch die Nähmaschine führen. Dieser Vorgang erfordert relativ viel Zeit und Sorgfalt, da der umgefaltete Randstreifen nur schmal ist und sich somit nach dem Umfalten leicht wieder öffnet und da die Naht sehr dicht an der Faltkante verlaufen soll.In both cases, the fabric strip is transferred unchanged from the loading station to the underlay. There are now cases in which the fabric strip has to be folded before being placed on the base, for example a piece of fabric to be sewn to the fabric strip. For example, in the case of trouser pockets, the aim is not only to pierce the fabric strip forming the pocket trim at its seam with the pocket pouch, since the wearer of the trousers easily gets caught on the threads of this seam and the seam tears open. Rather, the pocket trim should first be folded in this seam area and then sewn to the pocket bag. For this process, the seamstress must first fold the strip of fabric forming the pocket trim, place the strip of fabric in the folded state on the pocket bag and pass both parts by hand through the sewing machine. This process requires a relatively large amount of time and care, since the folded edge strip is only narrow and therefore easily opens again after folding and because the seam should run very close to the folded edge.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die es ermöglicht, einen Stoffstreifen aus der Einlegestation aufzunehmen und in gefaltetem Zustand auf der Unterlage abzulegen.The invention has for its object to provide a device of the type mentioned, which makes it possible to pick up a strip of fabric from the insertion station and to place it in the folded state on the base.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Der auf die Auflageplatte an den Anschlag aufgelegte Stoffstreifen wird durch den Faltsteg geringfügig hochgewölbt, so daß dieser gewölbte Abschnitt in die Öffnung der Ubertragungsklammer hineinragt. Wird diese nun geschlossen, so wird dabei der Stoffstreifen gefaltet und in gefaltetem Zustand festgehalten. In dieser Stellung der Übertragungsklammer kann der Stoffstreifen nicht abgelegt werden, ohne daß die Gefahr besteht, daß beim Öffnen der Klammer sich der Stoffstreifen wieder auffaltet. Aus diesem Grunde wird vor oder während des Überganges der Übertragungsklammer aus der Aufnahmestellung in die Ubergabestellung die Übertragungsklammer derart verschwenkt, daß der zwischen den Klemmleisten eingespannte Bereich des Stoffstreifens nicht mehr im wesentlichen senkrecht zur Auflagefläche bzw. zur Unterlage sondern parallel zu dieser gerichtet ist. In dieser . Stellung kann der Stoffstreifen dann flach auf die Unterlage aufgelegt und beispielsweise von einer Stoffklammer übernommen werden, der ihn zusammen mit einem zu vernähenden weiteren Stoffteil zur Nähstelle führt. Hierzu ist es vorteilhaft, wenn der mit der jeweils anderen Klemmleiste zum Klem- - men des Stoffteiles zusammenwirkende Abschnitt der Klemmleiste, die in der Übergabestellung der Unterlage zugewandt ist, als dünne Lamelle ausgebildet ist, so daß zwischen der Unterlage und der auf ihr aufliegenden Klemmleiste nur eine unmerkliche Stufe entsteht und das Stoffteil somit in gefaltetem Zustand praktisch völlig eben auf der Unterlage abgelegt werden kann.The fabric strip placed on the support plate at the stop is arched up slightly by the folding web, so that this arched section projects into the opening of the transfer clip. If this is now closed, the fabric strip is folded and held in the folded state. In this position of the transfer clip, the cloth strip cannot be put down without the risk that the cloth strip will unfold again when the clip is opened. For this reason, before or during the transition of the transfer clip from the receiving position into the transfer position, the transfer clip is pivoted in such a way that the region of the strip of material clamped between the terminal strips is no longer directed essentially perpendicular to the support surface or to the base, but parallel to it. In this . Position, the strip of fabric can then be placed flat on the base and taken over, for example, by a fabric clip, which, together with another piece of fabric to be sewn, guides it to the sewing point. For this purpose, it is advantageous if the section of the clamping strip which interacts with the other clamping strip for clamping the fabric part and which faces the base in the transfer position is designed as a thin lamella, so that between the base and the terminal strip resting thereon only an imperceptible step arises and the fabric part can thus be placed practically completely flat on the base when folded.

Wenn während des Klemmens des Stoffteiles nur eine der Klemmleisten bewegt wird, während die andere Klemmleiste gegenüber der Auflageplatte ruht, ist es zweckmäßig, wenn der Faltsteg senkrecht zu seiner Längsrichtung und parallel zur Auflagefläche der Auflageplatte gegen Federkraft verstellbar gelagert ist. Anderenfalls wäre es erforderlich, die beim Klemmvorgang ruhende Klemmleiste beim Aufsetzen der Übertragungsklammer auf die Auflageplatte exakt neben den Faltsteg zu setzen, um die Klammer anschließend wirklich schließen zu können. Durch die federnde Lagerung des Faltsteges wird dieser jedoch beim Schließen der Klammer mitgenommen, gleitet beim Abheben der Übertragungsklammer von der Auflageplatte zwischen den gefalteten Stoffabschnitten heraus und kehrt aufgrund der Federkraft wieder in seine Ausgangsstellung zurück. Durch dieses Bewegungsspiel des Faltsteges treten keine wesentlichen Justageprobleme beim Einstellen der Aufnahmestellung der Übertragungsklammer relativ zum Faltsteg auf.If, during clamping of the fabric part, only one of the clamping strips is moved while the other clamping strip is resting relative to the support plate, it is expedient if the folding web is adjustable against spring force perpendicular to its longitudinal direction and parallel to the support surface of the support plate. Otherwise, it would be necessary to place the terminal block, which is stationary during the clamping process, exactly next to the folding web when the transfer clip is placed on the support plate, in order to then be able to really close the clip. Due to the resilient mounting of the folding web, however, it is taken along when the clip is closed, slides out between the folded fabric sections when the transfer clip is lifted off, and returns to its original position due to the spring force. This movement play of the folding web means that there are no significant adjustment problems when setting the receiving position of the transfer clip relative to the folding web.

Um die Breite des Randabschnittes einstellen zu können, der von der Übertragungsklammer erfaßt wird, kann der Faltsteg so angeordnet sein, daß er senkrecht zur Auflagefläche der Auflageplatte verstellbar ist. Der beispielsweise von einer Stahllamelle gebildete Faltsteg ist also zweckmäßigerweise an seiner Halterung angeschraubt, wobei die Schrauben den Faltsteg in Langlöchern durchsetzen, so daß dieser verstellt werden kann.In order to be able to adjust the width of the edge section which is gripped by the transmission clip, the folding web can be arranged in such a way that it can be adjusted perpendicularly to the support surface of the support plate. The folding web, for example formed by a steel lamella, is therefore expediently screwed to its holder, the screws penetrating the folding web in elongated holes so that it can be adjusted.

Um unterhalb der Auflageplatte ein weiteres Stoffteil bereitlegen zu können, auf das der zu übertragende Stoffstreifen aufgelegt wird, ist es zweckmäßig, wenn die Auflageplatte aus einem transparenten Material hergestellt ist, so daß sie der Bedienungsperson beim Bereitlegen des Stoffteiles nicht die Sicht nimmt.In order to be able to provide a further piece of fabric below the support plate on which the strip of material to be transferred is placed, it is expedient if the support plate is made of a transparent material so that it does not obscure the operator when the fabric part is ready.

Bei einer bevorzugten Ausführungsform ist die Klemmleiste um die Schwenkachse schwenkbar an einem Bügel gelagert, wobei die Übertragungsklammer mittels eines ersten Arbeitszylinders verstellbar ist, der einerseits an einem bügelfesten Teil und andererseits an dieser Klemmleiste angreift. Die andere Klemmleiste ist zweckmäßigerweise an der mit dem Bügel verbundenen Klemmleiste verschiebbar geführt und mittels eines mit beiden Klemmleisten verbundenen zweiten Arbeitszylinders im Sinne eines Öffnens und Schließens der Übertragungsklammer verstellbar. Die Klemmleisten werden also beim Öffnen und Schließen der Übertragungsklammer geradlinig gegeneinander bewegt.In a preferred embodiment, the terminal block is pivotally mounted on a bracket about the pivot axis, the transmission clamp is adjustable by means of a first working cylinder, which engages on the one hand on a bracket-fixed part and on the other hand on this terminal strip. The other terminal strip is expediently guided displaceably on the terminal strip connected to the bracket and adjustable by means of a second working cylinder connected to both terminal strips in the sense of opening and closing the transmission clip. The terminal strips are thus moved against each other in a straight line when opening and closing the transmission clip.

Die Verstellung der Übertragungsklammer zwischen der Aufnahmestellung und der Übergabestellung bzw. umgekehrt kann in der Weise erfolgen, daß der Bügel an einem Rahmen höhenverstellbar geführt und mittels eines zwischen Rahmen und Bügel wirkenden dritten Arbeitszylinders verstellbar ist und daß der Rahmen an einem Ständer um eine zur Auflageplatte parallele Achse verschwenkbar gelagert und mittels eines zwischen dem Ständer und dem Rahmen wirkenden vierten Arbeitszylinders verstellbar ist, wobei die Auflageplatte relativ zur Unterlage um einen dem Schwenkwinkel des Rahmens entsprechenden Winkel geneigt ist. Nach dem Schließen der Übertragungsklammer in der Einlegestation wird beispielsweise die Übertragungsklammer zunächst von der Auflageplatte abgehoben und anschließend verschwenkt. Daraufhin wird der Rahmen an dem Ständer so weit verschwenkt, daß die Übertragungsklammer an der Auflageplatte vorbei auf die Unterlage abgesenkt werden kann. Anschließend kann der auf die Unterlage abgelegte Stoffstreifen beispielsweise von einer Stoffklammer in seinem gefalteten Zustand auf der Unterlage festgeklemmt werden, worauf die Übertragungsklammer geöffnet und wieder von der Unterlage abgehoben werden kann.The adjustment of the transmission clamp between the receiving position and the transfer position or vice versa can be done in such a way that the bracket is guided in a height-adjustable manner on a frame and is adjustable by means of a third working cylinder acting between the frame and the bracket and that the frame is supported on a stand around a to the support plate parallel axis is pivotally mounted and is adjustable by means of a fourth working cylinder acting between the stand and the frame, the support plate being inclined relative to the base by an angle corresponding to the pivoting angle of the frame. After the transfer clip has been closed in the loading station, the transfer clip is, for example, first lifted off the support plate and then pivoted. The frame on the stand is then pivoted so far that the transmission clip can be lowered past the support plate onto the support. Subsequently, the fabric strip placed on the base can be clamped, for example, by a fabric clip in its folded state on the base, whereupon the transfer clip can be opened and lifted off the base again.

Mit der vorstehend beschriebenen Vorrichtung ist ein problemloses und absolut exaktes Auflegen eines Stoffstreifens in gefaltetem Zustand auf eine Unterlage möglich, wobei die Bedienungsperson lediglich beispielsweise ein erstes Stoffteil auf der Unterlage bereitstellen und den daraufzulegenden Stoffstreifen auf die Auflageplatte legen muß. Das Falten und Übertragen des Stoffstreifens sowie das Vernähen der beiden Stoffteile miteinander kann dann selbsttätig erfolgen.With the device described above, a problem-free and absolutely exact placement of a strip of fabric in the folded state on a support is possible, the operator only having to provide, for example, a first piece of fabric on the support and place the strip of fabric to be placed on the support plate. The folding and transferring of the fabric strip and the sewing of the two fabric parts to one another can then take place automatically.

In Fig. 1 erkennt man eine allgemein mit 10 bezeichnete Einlegestation, für einen Stoffstreifen 12, der mittels einer allgemein mit 14 bezeichneten Übertragungsklammer gefaltet und in gefaltetem Zustand auf einem Nähmaschinentisch 16 liegenden weiteren Stoffteil 18 abgelegt werden soll, so daß er anschließend zusammen mit diesem Stoffteil 18 mittels einer Stoffklammer 20 unter einer Nähmaschine 22 hindurchgeführt und mit dem Stoffteil 18In Fig. 1 you can see a generally designated 10 insertion station, for a strip of fabric 12, which is folded by means of a generally designated 14 transfer clip and in the folded state on a sewing machine table 16 lying further fabric part 18, so that it is then together with this The fabric part 18 is passed under a sewing machine 22 by means of a fabric clip 20 and with the fabric part 18th

Die Einlegestation umfaßt eine Auflageplatte 24, die vorzugsweise aus einem transparenten Material besteht, so daß sie die Sicht der Bedienungsperson auf die Unterlage, d.h. den Nähmaschinentisch 16 oder das Stoffteil 18 nicht behindert. Die Auflageplatte 24 ist gegenüber dem Nähmaschinentisch 16 geneigt und über einen Tragebügel 26 an einem nähmaschinentischfesten Ständer gehalten.The loading station comprises a support plate 24, which is preferably made of a transparent material, so that the operator's view of the base, i.e. does not hinder the sewing machine table 16 or the fabric part 18. The support plate 24 is inclined with respect to the sewing machine table 16 and held on a stand fixed to the sewing machine table via a carrying bracket 26.

Nahe ihrem tiefer gelegenen Rand trägt die Auflageplatte 24 eine nach oben abstehende Anschlagleiste 28. In einem Abstand von der Anschlagleiste 28 weist die Auflageplatte 24 einen parallel zur Anschlagleiste 28 verlaufenden Schlitz 30 auf, der gemäß Fig. 5 in einem mittleren Bereich durch eine schmale Brücke 32 unterbrochen sein kann. Durch den Schlitz 30 ragt ein Faltsteg 34 in Form einer dünnen Stahllamelle, wobei die Brücke 32 in eine entsprechende Aussparung des Faltsteges 34 eingreift. Der Faltsteg 34 ist an einer unterhalb der Auflageplatte 24 angeordneten Leiste 36 mit Schrauben 38 in der Weise befestigt, daß er senkrecht zur Auflageplatte 24 verstellbar ist. Damit kann das Maß eingestellt werden, um das der Faltsteg 34 über die Auflagefläche 40 der Auflageplatte 24 hinausragt.Near its lower edge, the support plate 24 carries an upwardly projecting stop bar 28. At a distance from the stop bar 28, the support plate 24 has a slot 30 running parallel to the stop bar 28, which is shown in FIG. 5 in a central area by a narrow bridge 32 can be interrupted. A folding web 34 in the form of a thin steel lamella projects through the slot 30, the bridge 32 engaging in a corresponding recess in the folding web 34. The folding web 34 is fastened to a bar 36 arranged below the support plate 24 with screws 38 in such a way that it can be adjusted perpendicularly to the support plate 24. The extent to which the folding web 34 projects beyond the contact surface 40 of the contact plate 24 can thus be set.

Die Leiste 36 ist mittels parallel zur Auflageplatte 24 gerichteten Bolzen 42 in einer Schiene 44 verschiebbar geführt, die an der Unterseite der Auflageplatte 24 befestigt ist. Dabei wird die Leiste 36 durch Federn 46 in ihre der Schiene 44 ferne Stellung vorgespannt, wobei die Federn 46 die Bolzen 42 umgeben und sich einerseits an der Schiene 44 und andererseits an einem Bund 48 des jeweiligen Bolzens 42 abstützen. Ein weiterer Bund 50 auf der Rückseite der Schiene 44 verhindert das Herausrutschen der Bolzen 42 aus der Schiene 44. Somit ist auch der Faltsteg innerhalb des Schlitzes oder Spaltes 30 senkrecht zur Anschlagleiste 28 gegen die Federvorspannung der Federn 46 frei verstellbar.The strip 36 is displaceably guided by means of bolts 42 directed parallel to the support plate 24 in a rail 44 which is fastened to the underside of the support plate 24. The strip 36 is biased by springs 46 into its position remote from the rail 44, the springs 46 surrounding the bolts 42 and being supported on the rail 44 on the one hand and on a collar 48 of the respective bolt 42 on the other hand. Another collar 50 on the back of the rail 44 prevents the bolts 42 from slipping out of the rail 44. Thus, the folding web within the slot or gap 30 is also freely adjustable perpendicular to the stop bar 28 against the spring preload of the springs 46.

Die Übertragungsklammer umfaßt gemäß den Fig. 1 bis 4 eine erste winkelförmige Klemmleiste 52, die an den Längsenden ihres einen Schenkels mit den U-Schenkeln 54 eines U-förmigen Bügels 56 gelenkig verbunden ist, so daß die Klemmleiste 52 um eine zu ihrer Längsrichtung parallele Schwenkachse 58 an dem Bügel 56 schwenkbar gelagert ist. Eine mit dem anderen Schenkel der Klemmleiste 52 zusammenwirkende zweite Klemmleiste 60 ist an der Klemmleiste 52 mit diese durchsetzenden Bolzen 62 verschiebbar gelagert. An der ersten Klemmleiste 52 ist ein pneumatisch betätigter Arbeitszylinder 64 befestigt, dessen nicht sichtbare Kolbenstange mit der Klemmleiste 60 verbunden ist. so daß der Arbeitszylinder 64 ein Schließen und Öffnen der Übertragungsklammer 14 bewirken kann. Dabei ist es selbstverständlich möglich, den Arbeitszylinder 64 entweder als doppelt wirkenden Zylinder auszubilden oder die Übertragungsklammer 14 in eine ihrer Stellungen vorzuspannen und in die jeweils andere Stellung mit dem Arbeitszylinder 64 zu verstellen.1 to 4, the transmission clamp comprises a first angular clamping strip 52, which is articulated at the longitudinal ends of its one leg to the U-legs 54 of a U-shaped bracket 56, so that the clamping strip 52 is parallel to its longitudinal direction Pivot axis 58 is pivotally mounted on the bracket 56. A second clamping bar 60 cooperating with the other leg of the clamping bar 52 is slidably mounted on the clamping bar 52 with bolts 62 passing through it. A pneumatically operated working cylinder 64 is fastened to the first clamping bar 52, the piston rod (not visible) of which is connected to the clamping bar 60. so that the working cylinder 64 can close and open the transmission clip 14. It is it is of course possible to either design the working cylinder 64 as a double-acting cylinder or to bias the transmission clamp 14 into one of its positions and to adjust it to the other position with the working cylinder 64.

Die mit der Klemmleiste 52 zusammenwirkende Klemmfläche der Klemmleiste 60 befindet sich an einer mit letzterer fest verbundenen dünnen Stahllamelle 66. Der Zweck dieser Maßnahme wird später noch näher erläutert.The clamping surface of the clamping strip 60 which interacts with the clamping strip 52 is located on a thin steel lamella 66 which is firmly connected to the latter. The purpose of this measure will be explained in more detail later.

Die Übertragungsklammer 14 ist an dem Bügel 56 um mindestens 90° zwischen den in den Fig. 2 und 3 dargestellten Stellungen verschwenkbar. Das Verschwenken erfolgt mittels eines pneumatisch betätigbaren Arbeitszylinders 68, der an einer mit dem Bügel 56 starr verbundenen Strebe 70 angelenkt ist und mit seiner Kolbenstange 72 an einem mit der Klemmleiste 52 starr verbundenen Winkel 74 angreift.The transmission clip 14 can be pivoted on the bracket 56 by at least 90 ° between the positions shown in FIGS. 2 and 3. The pivoting takes place by means of a pneumatically actuated working cylinder 68 which is articulated on a strut 70 rigidly connected to the bracket 56 and engages with its piston rod 72 on an angle 74 rigidly connected to the terminal strip 52.

Der Bügel 56 ist mittels Führungsstangen 76 in einem Rahmen 78 in Fig. 2 vertikal verschiebbar geführt und mittels eines Arbeitszylinders 80 verstellbar, der über einen Winkel 83 an dem Rahmen 78 befestigt ist und mit seiner Kolbenstange 82 an einer mit dem Bügel 56 fest verbundenen Nase 84 angreift. Der Arbeitszylinder 80 wird ebenfalls vorzugsweise pneumatisch betätigt.The bracket 56 is guided vertically displaceably by means of guide rods 76 in a frame 78 in FIG. 2 and is adjustable by means of a working cylinder 80 which is attached to the frame 78 via an angle 83 and with its piston rod 82 on a nose which is firmly connected to the bracket 56 84 attacks. The working cylinder 80 is also preferably operated pneumatically.

Der Rahmen 78 ist einem Ständer 86 um eine zur Schwenkachse 58 parallele Schwenkachse 88 schwenkbar gelagert und mit Hilfe eines pneumatisch betätigbaren Arbeitszylinders 90 verstellbar, der an dem Ständer 86 angelenkt ist und mit seiner Kolbenstange 92 an dem Rahmen 78 angreift. Der Rahmen 78 und mit ihm die Übertragungsklammer 14 können auf diese Weise zwischen der in der Fig. 2 dargestellten vertikalen Stellung und einer in der Fig. 1 angedeuteten schrägen Stellung in Richtung des Doppelpfeiles B um einen Winkel verschwenkt werden, der im wesentlichen dem Neigungswinkel der Auflageplatte 24 gegenüber dem Nähmaschinentisch 16 entspricht.The frame 78 is mounted on a stand 86 so as to be pivotable about a pivot axis 88 parallel to the pivot axis 58 and is adjustable with the aid of a pneumatically actuated working cylinder 90 which is articulated on the stand 86 and engages the frame 78 with its piston rod 92. The frame 78 and with it the transmission clip 14 can be pivoted in this way between the vertical position shown in FIG. 2 and an inclined position indicated in FIG. 1 in the direction of the double arrow B by an angle which is essentially the angle of inclination of the Platen 24 corresponds to the sewing machine table 16.

Die soweit beschriebene Vorrichtung arbeitet folgendermaßen:The device described so far works as follows:

Zunächst legt die Bedienungsperson ein erstes Stoffteil 18 auf den Nähmaschinentisch 16. Anschließend legt sie den Stoffstreifen 12 so auf die Auflageplatte 24 daß er mit einer Kante an der Anschlagleiste 28 angliegt. Dabei wird der Stoffstreifen durch den über die Auflagefläche 40 der Auflageplatte 24 hinausragenden Faltsteg 34 in dem Bereich des Schlitzes 30 nach oben gewölbt, wie dies in Fig. 1 zu erkennen ist. Anschließend betätigt die Bedienungsperson einen Schalter, so daß die Übertragungsklammer 14 mittels des Arbeitszylinders 90 über die Auflageplatte 24 geschwenkt und durch Betätigung des Arbeitszylinders 80 auf die Auflageplatte 24 abgesenkt wird, so daß sie die in der Fig. 1 dargestellte Stellung einnimmt. In dieser Stellung ragt der Faltsteg mit dem hochgewölbten Abschnitt des Stoffstreifens 12 in die Klemmöffnung der Übertragungsklammer 14 hinein. Wird nun der Arbeitszylinder 64 betätigt, so wird die Klemmleiste 60 in Richtung auf die Klemmleiste 52 bewegt, wobei der in die Klemmöffnung hineinragende doppelte Stoffabschnitt zusammen mit dem Faltsteg 34 eingeklemmt wird. Dabei folgt der gegen Federkraft frei bewegliche Faltsteg 34 der Bewegung der Klemmleiste 60. Wird die Übertragungsklammer 14 durch Betätigung des Arbeitszylinders 80 anschließend von der Auflageplatte 24 abgehoben, so hält die Übertragungsklammer 14 den gefalteten Stoffstreifen 12 fest, während der Faltsteg 34 zwischen den Klemmleisten 60 und 52 herausrutscht.First of all, the operator places a first piece of fabric 18 on the sewing machine table 16. Then, he places the strip of fabric 12 on the support plate 24 in such a way that it abuts the stop bar 28 with one edge. The strip of fabric is arched upward in the region of the slot 30 by the folding web 34 projecting beyond the contact surface 40 of the contact plate 24, as can be seen in FIG. 1. Then the operator actuates a switch so that the transfer bracket 14 is pivoted by means of the working cylinder 90 over the support plate 24 and lowered by actuating the working cylinder 80 on the support plate 24 so that it assumes the position shown in FIG. 1. In this position, the folding web with the arched section of the fabric strip 12 projects into the clamping opening of the transmission clip 14. If the working cylinder 64 is now actuated, the clamping strip 60 is moved in the direction of the clamping strip 52, the double section of material projecting into the clamping opening being clamped together with the folding web 34. The folding web 34, which is freely movable against spring force, follows the movement of the terminal strip 60. If the transmission clip 14 is then lifted off the support plate 24 by actuating the working cylinder 80, the transmission clip 14 holds the folded fabric strip 12 in place, while the folding web 34 between the clamping strips 60 and 52 slips out.

Nun wird zunächst die Übertragungsklammer 14 aus der in den Fig. 1 und 2 dargestellten Stellung in die in der Fig. 3 dargestellte Stellung im Uhrzeigersinn durch Betätigung des Arbeitszylinders 68 verschwenkt. Anschliessend wird der Rahmen 78 zusammen mit der Übertragungsklammer 14 durch Betätigung des Arbeitszylinders 90 in die in der Fig. 2 dargestellte vertikale Stellung verschwenkt und die Ubertragungsklammer 14 durch Betätigung des Arbeitszylinders 80 in die in der Fig. 3 dargestellte Stellung in Richtung auf den Nähmaschinentisch 16 abgesenkt. Wie man erkennt, liegt nun die Klemmleiste 60 mit ihrer Klemmlamelle 66 auf dem Stoffteil 18 auf, so daß wegen der geringen Dicke der Klemmlamelle 66 der Stoffstreifen 12 in gefaltetem Zustand praktisch eben auf dem Stoffteil 18 aufliegt. Bevor die Übertragungsklammer geöffnet wird, werden die beiden Stoffteile mittels der Stoffklammer 20 gegen den Nähmaschinentisch 16 geklemmt, so daß sich der gefaltete Abschnitt des Stoffstreifens 12 nicht mehr auffalten kann. Anschließend kann die Übertragungsklammer 14 geöffnet und durch Betätigung des Arbeitszylinders 80 angehoben werden. Die Stoffklammer 20 führt dann die beiden miteinander zu vernähenden Stoffteile 18 und 12 unter der Nähmaschine 22 hindurch, so daß die beiden Teile nahe dem gefalteten Rand des Stoffteils 12 miteinander vernäht werden können.Now the transmission clip 14 is first pivoted clockwise from the position shown in FIGS. 1 and 2 into the position shown in FIG. 3 by actuating the working cylinder 68. The frame 78 is then pivoted together with the transfer clip 14 by actuating the working cylinder 90 into the vertical position shown in FIG. 2 and the transfer clip 14 by actuating the working cylinder 80 into the position shown in FIG. 3 in the direction of the sewing machine table 16 lowered. As can be seen, the clamping strip 60 now lies with its clamping lamella 66 on the fabric part 18, so that because of the small thickness of the clamping lamella 66 the fabric strip 12 lies practically flat on the fabric part 18 in the folded state. Before the transfer clip is opened, the two fabric parts are clamped against the sewing machine table 16 by means of the fabric clip 20, so that the folded section of the fabric strip 12 can no longer unfold. The transmission clip 14 can then be opened and raised by actuating the working cylinder 80. The fabric clip 20 then guides the two fabric parts 18 and 12 to be sewn together under the sewing machine 22, so that the two parts can be sewn together near the folded edge of the fabric part 12.
