Description

Aus mehreren unmittelbar nebeneinanderliegenden Feilenblättern bestehende zusammengesetzte Feile Bei den bisher bekannten, aus mehreren unmittelbar nebeneinanderliegenden Feilenblättern bestehenden zusammengesetzten Feilen wirken die Feilenblätter beim Feilen nur nach ein und derselben Richtung. Solche Feilen lassen sich bei Kraftantrieb nicht freihändig an das Werkstück ansetzen; es entstehen Rückschläge, bzw. die Feile läuft aus dem Werkstück heraus.Consists of several file blades lying directly next to one another composite file In the previously known file, consisting of several directly adjacent The file blades act on the existing composite files Only file in one and the same direction. Such files can be powered do not apply freehand to the workpiece; kickbacks or the file occur runs out of the workpiece.

Um diese Feilen bei Kraftantrieb freihändig an das Werkstück ansetzen zu können, sind bei der vorliegenden Erfindung die nebeneinanderliegenden Feilen-(Säge-) Blätter beim Feilen in entgegengesetzter Richtung hin und her bewegbar. Während also das eine Feilen-bzw. Sägeblatt nach der einen Richtung wirkt (mit entsprechend gestellten Zähnen bzw. Feilhieben), wirkt gleichzeitig das benachbarte Feilen- bzw. Sägeblatt mit entsprechend gestellten Zähnen nach der anderen Richtung. Hierdurch werden die auftretenden Kräfte gegeneinander aufgehoben, und man erzielt mühelos eine genaue Arbeit.In order to apply these files to the workpiece using a power drive, hands-free to be able to, are in the present invention the adjacent file (saw) The blades can be moved back and forth in the opposite direction when filing. While So the one filing or. The saw blade acts in one direction (with corresponding teeth or file cuts), the neighboring file or file cuts act at the same time. Saw blade with correspondingly set teeth in the other direction. Through this the occurring forces are canceled out against each other, and one achieves effortlessly an accurate job.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt. Von den Einzelfeilen a, b, c, d, e, f wirken a, c, e nasch links, während gleichzeitig b, a', f nach rechts wirken. Die Form der Feilen kann beliebig sein. Das Werkzeug kann auch aus nur zwei in entgegengesetzter Richtung wirkenden Feilen bestehen. Die Einzelfeilen bzw. -blätter können auch aus endlosen Bändern oder Ketten bestehen.The subject of the invention is shown in the drawing. Of the individual files a, b, c, d, e, f, a, c, e act to the left, while at the same time b, a ', f act to the right. The shape of the files can be any. The tool can also consist of only two files acting in opposite directions. The individual files or blades can also consist of endless belts or chains.
