A protective cover (1) for a zone of a machine tool, within whose area a working part of the machine moves along an operating path. The cover (1) comprises a plurality of cover elements consisting of a fixed cover element (2a) which can be attached to the machine, a mobile element (2e) connected to the working part and a plurality of mobile cover elements (2b, 2c, 2d) positioned between the fixed cover element (2a) and the mobile cover element (2e). The cover elements (2a, 2b, 2c, 2d, 2e) are arranged in order of decreasing size and lie around the working part, connected to one another by a first support and guide rod (9) and a second support and guide rod (10), at a given distance from one another. Between the cover elements (2a, 2b, 2c, 2d, 2e) and the rods (9, 10) there is a plurality of sliders (12b, 13b, 12c, 13c, 12d, 13d, 12e, 13e, 16, 17) designed to guide the mobile cover elements (2b, 2c, 2d, 2e) in a direction parallel to and in a direction at right angles to the rods (9, 10), during movement of the working part, keeping the working zone covered. <IMAGE> |
