CA 2320874

The invention relates to a protective hood (10) for wood milling machines which serves to cover a milling spindle (16) protruding vertically upwards from a horizontal machine stand (12). The protective hood (10) consists of two lateral walls (20), which are connected to each other by a top (26) and a rear wall (22), and a front-side, height-adjustable protective shield (130). The protective hood (10) also comprises a coupling sleeve (126) for a suction device and can be adjustably mounted on the machine stand (12). A retaining element (52) for the removable attachment of a butt plate (54) is movably fixed to both lateral walls (20) of the protective hood (10). In this way the protective hood (10) is at all times available as a base element and when a user changes from curve milling to a milling operation using the butt plate the butt plates (54) can easily be installed.

L'invention concerne un capot de protection (10) pour fraiseuses à bois, qui sert à recouvrir une broche de fraise (16) faisant saillie verticalement d'une table de machine (12) horizontale. Le capot de protection (10) est constitué de deux parois latérales (20) reliées l'une à l'autre par un couvercle (26) et par une paroi arrière (22), et d'un bouclier (130) avant, déplaçable en hauteur. Le capot de protection (10) est pourvu d'un manchon de raccordement (126) auquel est raccordé un dispositif d'aspiration, et il peut être fixé, de façon à pouvoir être déplacé, sur la table de machine (12). Sur chacune des deux parois latérales (20) du capot de protection (10) est fixé, de façon libérable, un organe de retenue (52) servant à fixer, de façon amovible, une plaque de butée (54). De cette façon, le capot de protection (10) est en permanence à disposition en tant qu'élément de base, de sorte que lorsque l'on passe du fraisage en arc au fraisage en butée, on peut rapporter de façon simple les plaques de butée (54).
