und eine Stange 69 mit dem zum Verändern der Geschwindigkeit des Vorschubes dienenden Trethebel 71 verbunden ist.
Damit der elektrische Strom und der durch denselben hervorgebrachte Wärmegrad des Werkzeuges geregelt werden kann, fliesst, er durch einen Widerstandskasten 73. An dem Wider- standskasten 73 ist ein Hebel 75 derart angebracht, dass der Widerstand durch Senken des unteren

Zapfen 79, 81 mit dem Arm 67 verbunden. Wenn das Spitzenende des Trethebels zwecks Verlangsamens des Vorschubes des Werkstückes herabgedrückt wird, so wird der elektrische Strom geschwächt und der Wärmegrad des Werkzeuges erfährt eine entsprechende Herabsetzung. Wenn das Fersenende des Trethebels herabgedrückt wird, so erfährt die Geschwindigkeit des Vorschubes eine Beschleunigung und der Wärme : trad des Werkzeuges wird dementsprechend erhöht.
Diese Anordnung ist besonders vorteilhaft, da Lederstücke mit, verhältnismässig geraden Kanten rasch durch die Maschine hindurchgeführt werden können, während bei der Bearbeitung von Lederstt1cken mit kurvenförmigen Kanten die Geschwindigkeit des Vorschubes herabgesetzt wird, wobei der Wärmegrad des Werkzeuges ohne weiteres Zutun geregelt wird.
Das in Fig. 7 dargestellte Werkzeug 85 wird durch eine Gasleitung 87 erhitzt. Das Werkzeug kann mit einem hohlen Platinkörper versehen sein, der durch Gas zum Glühen gebracht wird, wie es z. B. bei den in der Holzbrandteehnik Anwendung findenden Vorrichtungen der Fall ist.

befestigt werden und das Lederstück 100 wird an dem ortsfesten Werkzeug vorbeigeführt.
PATENT-ANSPRÜCHE :
1. Verfahren zum FertigmatheT1 von Lederkanten, dadurch gekennzeichnet, dass man eine Seite des Lederrandes zusammenschrumpfen lässt. wobei sich die andere Seite des Lederrandes gegen die zusammengeschrumpfte Seite krümmt.

and a rod 69 is connected to the pedal lever 71 for changing the speed of the feed.
So that the electrical current and the degree of heat produced by the tool can be regulated, it flows through a resistance box 73. A lever 75 is attached to the resistance box 73 in such a way that the resistance is reduced by lowering the lower
EMI3.2
Pins 79, 81 are connected to arm 67. If the tip end of the pedal lever is pressed down in order to slow down the advance of the workpiece, the electrical current is weakened and the heat level of the tool experiences a corresponding reduction. When the heel end of the pedal is pressed down, the speed of the feed is accelerated and the heat: trad of the tool is increased accordingly.
This arrangement is particularly advantageous since pieces of leather with relatively straight edges can be passed quickly through the machine, while the speed of the feed is reduced when machining pieces of leather with curved edges, the temperature of the tool being regulated without further action.
The tool 85 shown in FIG. 7 is heated by a gas line 87. The tool can be provided with a hollow platinum body which is made to glow by gas, as is e.g. B. is the case with the devices used in wood fire engineering.

are attached and the piece of leather 100 is guided past the stationary tool.
PATENT CLAIMS:
1. A method for finishing math T1 of leather edges, characterized in that one side of the leather edge is allowed to shrink. with the other side of the leather edge curving against the shrunk side.
