Abstract
Process and apparatus for preventing collisions between two machine components, of which at least a first machine component is displaceable by means of a drive along a straight track relative to the second machine component such that the two components can collide, wherein for the simple and reliable prevention of such collisions a sequence of pulses is generated during movement of at least one of the two components relative to the other component by means of signal generating devices associated with the two machine components, namely such that the distance and/or the length and/or the height of consecutive pulses follows a function of the distance of the two components from one another, measured in track direction, and wherein the drive is controlled as a function of this sequence of pulses.
