CA 2299446

A strip-shaped or reciprocating knife has at least one elongated cutting blade (1) provided with a plurality of cutting teeth (2) and intermediate cutting gaps (5), the cutting teeth {2) being provided with additional, finer teeth (8). In order to achieve from beginning to end a smooth and clean cut of the goods to be cut, the additional teeth (8) are produced by providing opposite tooth spaces (9) on both sides of the knife arranged so close to one another that sharp teeth (12) are formed between the spaces. The additional teeth provided on both sides of the knife form a sharp cutting edge which is symmetrically arranged on both sides of the knife and extends over the cutting teeth (2).

Dispositif coupant alternatif ou sous forme de bande présentant au moins une lame coupante allongée (1) pourvue d'une pluralité de dents coupantes (2) et d'espaces coupants intermédiaires (5), ces dents coupantes (2) comportant une denture supplémentaire (8) plus fine. Dans le but d'exécuter une coupe et un sectionnement nets et sans bavures de l'article à couper et de simplifier la fabrication de ce dispositif, on produit la denture supplémentaire (8) au moyen d'entredents (9) situés des deux côtés du dispositif les uns en face des autres et placés à proximité si étroite les uns des autres qu'ils créent entre eux des dents pointues (12), de sorte que la denture supplémentaire des deux côtés du dispositif constitue un bord coupant aiguisé s'étendant au-dessus des dents coupantes (2) et symétriquement des deux côtés du dispositif coupant.
