<p>The sound-insulating and protective chamber largely encloses the automatic machine, excepting the opposite extremities of its base which have removable covers (301) and the means (15) for feeding in the wrapping material and the electrical control panel (16). The chamber is closed at the anterior front by an outer door (22) which is convex towards the exterior in plan view and supported from above by an arm (21, 121) that pivots upon a vertical spindle (18) fixed to the top of said chamber. Integral with the bottom and top of the door are respective projecting plates (31, 32) which, when the door is in a closed position, are located below and above, respectively, the horizontal fixed walls (3, 8) of the chamber. When the door is closed, its vertical sides touch those of the chamber aperture. <IMAGE></p> |
