Patent

CA 2601771

A dressing device (10,90) for sharpening or conditioning of a blade (18) or the like includes one or more disk pairs (36-40,108), each having a pair of disks (52,54,110,112) respectively presenting a series of circumferentially spaced, projecting teeth (64) with openings (66) therebetween. The disks (52,54,110,112) are oriented in face-to-face relationship with the teeth (64) thereof in meshed, intercalated relationship to thereby create circumferential dressing openings (76,122). The dressing surfaces (74) of the teeth (64) are of arcuate, concave configuration so as to create a desirable gothic-arch edge on a blade (18) or the like.

L'invention concerne un dispositif d'affûtage (10, 90) servant à aiguiser ou à entretenir une lame (18) ou analogue. Ce dispositif comprend au moins une paire de disques (36-40, 108), chaque paire comprenant une paire de disques (52, 54, 110, 112) présentant respectivement une série de dents saillantes (64), espacées de manière circonférentielle, des ouvertures (66) étant formées entre ces dents. Les disques (52, 54, 110, 112) sont orientés face à face, leurs dents (64) s'engrenant de manière intercalée, ce qui forme les ouvertures d'affûtage circonférentielles (76, 122). Les surfaces d'affûtage (74) des dents (64) présentent une configuration arquée concave de sorte à créer un bord en arc gothique désiré sur une lame (18) ou analogue.
