<p>Flat protective cover (1 ) with two degrees of freedom for tool machines, which can be associated with an operating member (A) movable along at least two main directions (D1, D2), comprising: at least a first flat covering element (2), operatively connected to said operating member (A); at least a second flat covering element (3); guide and retaining means (5a,5b,6a,6b,7a,7b,8a,8b) to mutually couple in a sliding way said covering elements, wherein said protective cover (1 ) further comprises an intermediate frame (4) between said first (2) and second (3) flat covering element, arranged for allowing mutual sliding of said flat elements (2,3) along the two mutually orthogonal main directions (D1, D2), and said guide and retaining means (5a,5b,6a,6b,7a,7b,8a,8b) comprise pairs of linear guides (5a,5b,6a,6b) arranged for co-operating by mutual sliding with pairs of blades (7a,7b,8a,8b).</p> |
