Trennwerkzeuges.Cutting tool.

Bei den bisher bekannt gewordenen Ausschneidemaschinen findet mittels scheren-, messer- oder stanzenartiger Werkzeuge ein wirkliches Schneiden des Stoffes statt. Hierbei zeigte sich jedoch der Übelstand, daß die Fäden dem Schneidwerkzeug auswichen und das Schneiden erschwerten bzw. ganz unmöglich machten. Auch wurde die Stoffunterlage durch die zahllosen Niedergänge des Schneid-Werkzeuges uneben, wodurch wiederum ein sauberes, faserloses Ausschneiden des Stoffes unmöglich gemacht wurde.In the previously known cutting machines, by means of scissors, knife-like or punch-like tools a real cutting of the fabric instead. Here However, the disadvantage showed that the threads evaded the cutting tool and made cutting difficult or even impossible. Also was the fabric underlay uneven due to the countless descents of the cutting tool, which in turn creates a clean, fiber-free cutting out of the fabric was made impossible.

Diese ganz erheblichen Übelstände werden nun bei der vorliegenden Maschine umgangenThese very considerable inconveniences are now circumvented in the present machine

15· und ein sauberes Abteilen gestickter Festonstreifen dadurch erzielt, daß der Stoff zwischen zwei stumpf aufeinander schlagenden Gliedern hindurchgeführt und durch die rasch aufeinanderfolgenden Schläge zerquetscht wird.15 · and a neat division of embroidered festoon strips achieved by the fact that the material between two butt hitting one another limbs is passed through and crushed by the rapidly successive blows.

Die Zeichnung veranschaulicht den Erfindungsgegenstand durch Fig. ι in einem Vertikalschnitt, durch Fig. 2 in einem Grundriß und durch Fig. 3 in einer teilweisen Stirnansicht. Fig. 4 ist ein Arbeitsschema.The drawing illustrates the subject matter of the invention through Fig. ι in a vertical section, through Fig. 2 in a plan and through FIG. 3 in a partial front view. Figure 4 is a working diagram.

Ein durch Streben 1 versteiftes Gestell 2 trägt eine Tischplatte 3 und einen Träger 4, in welchem das eine, eine Schnurscheibe 5 tragende Ende einer Welle 6 gelagert ist. Das andere Ende dieser Welle 6 ist im Vorderteil des Gestelles 2 gelagert und trägt eine Schnurscheibe 7, welche mit einem nicht gezeichneten Tretantrieb verbunden ist. Im Ober- und im Unterteil des Trägers 4 ist je eine spitz auslaufende Lagerschraube 8, g angeordnet, in welchen Schrauben ein Schwingrahmen 10 wagerecht schwingbar gelagert ist. Eine Feder 11 zieht den Schwingrahmen 10 nach vorn.A frame 2 stiffened by struts 1 carries a table top 3 and a carrier 4, in which the one end of a shaft 6 carrying a cord pulley 5 is mounted. That the other end of this shaft 6 is mounted in the front part of the frame 2 and carries a cord pulley 7, which is connected to a pedal drive, not shown. In the upper and in the lower part of the carrier 4 is one each pointed bearing screw 8, g arranged, in which screws an oscillating frame 10 is mounted so that it can swing horizontally. A spring 11 pulls the swing frame 10 forward.

In einem 'büchsenartigen Teil 12 des Schwingrahmens 10 ist ein Stift 13 auf- und abwärts beweglich und unter den Abwärtsdruck einer Feder 14 gestellt. Die Stärke des Federdruckes kann durch eine Gewindehülse 15 geregelt und die Abwärtsbewegung des Stiftes 13 durch eine Mutter 16 mit Gegenmutter 17 veränderbar begrenzt werden. Ein Querbolzen 18 des Stiftes 13. durchzieht eine Schrägnut 19 der Rahmenhülse 12. Mittels einer exzentrischen, auf den Bolzen 18 wirkenden Scheibe 20 (Fig. 1 und 3) kann der Stift 13 von Hand gehoben werden.In a 'sleeve-like part 12 of the swing frame 10, a pin 13 is up and movable downwards and placed under the downward pressure of a spring 14. The strength of the Spring pressure can be regulated by a threaded sleeve 15 and the downward movement of the Pin 13 can be variably limited by a nut 16 with a lock nut 17. A Cross bolt 18 of the pin 13 passes through an inclined groove 19 of the frame sleeve 12 an eccentric disk 20 (FIGS. 1 and 3) acting on the bolt 18, the pin 13 be lifted by hand.

Im unteren, gabelförmigen, unter der Tischplatte 3 befindlichen Arm des Schwingrahmens 10 ist eine Welle 21 gelagert, welche nebeneinander eine Schnurscheibe 22 und eine am Umfang gewellte Scheibe 23 trägt. Eine Schnur 24 verbindet die Scheiben 5 und 22 miteinander. Auf dem gewellten Umfang der Scheibe 23 ruht das freie, hammerkopfartige Ende eines um einen auf dem Schwingrahmen 10 gelagerten Zapfen 25 drehbaren Armes 26, in dessen Ende ein glasharter Stift 27 mittels einer Stellschraube 28 befestigt ist. Am Gestell 2 sind zwei Schaltwalzen 29 und 30 derart drehbar gelagert, daß sie mit ihren Umfangen die Tischplatte 3 um weniges über-In the lower, fork-shaped arm of the oscillating frame located under the table top 3 10, a shaft 21 is mounted, which side by side a cord pulley 22 and an am Corrugated disk 23 carries circumference. A cord 24 connects the disks 5 and 22 together. The free, hammer-head-like rests on the corrugated circumference of the disk 23 End of an arm 26 rotatable about a pin 25 mounted on the swing frame 10, in the end of which a glass-hard pin 27 is fastened by means of an adjusting screw 28. On the frame 2, two shift drums 29 and 30 are rotatably mounted in such a way that their circumferences slightly exceed the table top 3.

Claims

protrude. The forwardly extended axis 31 of each roller 29, 30 carries a cord pulley 32 or 33, which discs by means of a cord from the pedal drive with the required Speed can be driven. On the shift rollers 29, 30 rest pressure rollers 34, 35, which are from an on The upper part of the carrier 4 can be carried by means of a pivot 36 rotatably mounted frame 37.

By means of the pedal drive, which can, however, also be replaced by a mechanical power drive, the cord pulleys 32, 33 are set in a relatively slow rotation and the cord pulley 7 in a relatively rapid rotation. Through the cord pulley 5 there is still a translation into high speed, so that the corrugated disk 23 driven by the disk 5 rotates much faster than the rollers 29, 30 driven by the disks 32, 33. The end of the embroidery piece to be divided is between the Rollers 29, 34 out and advanced by these until it comes to rest under the pin 13. The fabric is now pulled by hand against the rollers 30, 35 and the oscillating frame 10 is swung back and forward again by the spring 11 in accordance with the contour of the festoon (see FIG. 4). When the pin 27 z. B. comes to stand at point χ (Fig. 4), the swing frame 10 is in the foremost, at point y in the rearmost working position. The substance, which is located between the pins 13 and 27, is crushed by the hammer-like blows of the pin 27 against the pin 13 acting as a resilient anvil and by the slight rotation of the pin 13 against the pin 27 as a result of the displacement of the bolt 18 in the Slit 19 simultaneously subjected to a crushing or tearing action, whereby the fibers are destroyed without actually cutting. The so separated parts of the end of the fabric are continued by hand, namely the embroidered part in a straight direction after the pair of rollers 30, 35, while the other part behind a small column 38 (Fig. 1 and 2) and from there only after the same pair of rollers 30, 35 is directed. This spreading apart of the two separate parts of the fabric end has the purpose of pulling the unembroidered fabric part at an angle and thereby, pulling the fabric part that has not yet been separated, always pushing the festoon edge against the pin 27. Since the lifting of the pin 13 is only a little and the embroidery of the festoon forms a bead which is not exceeded by the end of the pin 13, the pin 13 is always drawn to the festoon edge by the train of the spring 11 so that it this follows.

After the two parts of the end of the fabric have been inserted once between the pair of rollers 30, 35 the fabric is pulled forward by this pair of rollers and the machine then works automatically. A certain one Introducing the substance into the pair of rollers 29, 34 by hand is at least necessary. A ruler 39, which is guided along the festoon tips, facilitates the guiding of the fabric.
