Abstract
The present invention relates to a protective cover for at least one working part of a machine tool or similar machine, the machine part moving in a linear direction and the cover being designed to follow its movements so as to keep the corresponding zone inside the machine protected. The cover comprises a set of overlapping covering elements in the form of a first covering element that can be connected to the machine at the zone to be protected and a plurality of covering elements that move relative to each other and relative to the first covering element in the same linear direction as the working part of the machine moves. Each covering element has an opening through which a portion of the working machine part or its support can protrude outwards, the opening in the first covering element forming an area to be covered by the remaining covering elements, and the movable covering elements decreasing in size going from the inside to the outside.
