<p>An apparatus for decelerating the drive to a winding device for strip-material, having a length meter for the wound strip and a speed indicator for the strip to be wound, includes a computer which is adjustable to the nominal length of the strip of material and which brings the drive to a halt, at a predetermined rate of deceleration, as a function of the nominal length and of the instantaneous speed of the strip. The rate of deceleration is determined by two different curves, one of which would produce less, and the other more, than the nominal length if one or the other of these curves were to be exclusively effective after commencement of deceleration. The computer adjusts the rate of deceleration, in constant alternation, in accordance with the curves, changing over from one to the other as soon as it determines that the nominal length will be exceeded or not attained at the instantaneous prevailing rate of deceleration.</p> |
