Abstract

A broaching tool (12), in particular for cutting or broaching slits, has several mutually spaced disks (10) that rotate around a common axis (33) and are provided with segment-like cutting projections (18, 20, 22, 24) around its circumference. In order to cut or broach slits with as little effort as possible and in a single operation, the distance (26, 28, 30, 32) between successive segment-like projections (18, 20, 22, 24) on each of the disks (10) is at least approximately equal to or larger than the size of the segment-like projections in the circumferential direction, and projections on adjacent disks (10) are mutually offset in the circumferential direction at least in sections of the circumference of the disks.

GEÄNDERTE ANSPRÜCHE CHANGED CLAIMS [beim Internationalen Büro am 26. April 1996 (26.04.96) eingegangen; ursprünglicher Anspruch 2 geändert; ursprüngliche Ansprüche 1 und 7 gestrichen; weitere Ansprüche unverändert (1 Seite)][received at the International Bureau on April 26, 1996 (April 26, 1996); original claim 2 changed; original claims 1 and 7 deleted; further claims unchanged (1 page)] Räumwerkzeug (12), insbesondere zum Schneiden bzw. Räumen von Schlitzen, um¬ fassend mehrere zueinander beabstandete um eine gemeinsame Achse (33) drehbare Scheiben (10) mit umfangsseitigen zueinander beabstandeten segmentartigen Schneid¬ vorsprüngen (18, 20, 22, 24), d a d u r c h g e k e n n z e i c h n e t, daß aufeinanderfolgende segmentartige Vorsprünge (18, 20, 22, 24) einer jeden Scheibe (10) einen Abstand (26, 28, 30, 32) zueinander aufweisen, der zumindest in etwa gleich oder größer ist als jeweilige umfangsseitige Erstreckung der segmen¬ tartigen Vorsprünge, und daß Vorsprünge nebeneinanderliegender Scheiben (10) in Umfangsrichtung versetzt zueinander oder zumindest bereichsweise und derart versetzt zueinander verlaufen, daß die segmentartigen Vorsprünge der Scheiben in Seiten¬ ansicht des Räumwerkzeugs ( 12) eine geschlossene oder weitgehend geschlossene Kreisrinssfläche bilden.
