Abstract
Abstract A protective covering for a machine tool where work pieces can be mounted on a worktable comprises a loading door which can be pivoted between two end positions and which in a first end position closes the protective covering while in the second end position it clears an opening in the protective covering providing access to the work piece. The bottom of the loading door describes during this movement an upwardly curved locus extending above and across the work piece. It is proposed for this arrangement that the loading door be provided on its inside with a device for diverting liquid flowing down its inside towards the lateral edges and that the said loading door does not project beyond the outer contour of the said protective covering during its movement.
