Abstract
A protective device for a feed unit, especially for a spindle sleeve of a measuring machine, whereby the feed unit is surrounded by a jacket constituted of a multiplicity of springs, which touch the feed unit in the event of a collision and thereby produce electrical contacts, and in which the lower or bottom part of the feed unit is enclosed by a protective shield. The protective shield is constituted of individual screen parts which are displaceable or swingable out of their inoperative position, and which collectively enclose the lower part, wherein the screen parts are maintained in their inoperative position by means of magnets, and in which the screen parts in their tilted position touch at least one spring and thereby become electrically contactive.
