An apparatus for controlling the movements of a reed carriage of a warping machine during warping a package composed of successive adjacent warp sections wound onto the warping drum of the warping machine, wherein the displacement of the carriage for producing the shifted deposition of the warp section-layers during winding is accomplished by a reed carriage-displacement spindle which is driven by means of a pre-adjustable change-speed gearing as a function of the rotation of the warping drum. A processor is provided which, on the basis of infed data, determines the number of revolutions of the reed carriage-displacement spindle needed for shifting the reed carriage during winding a warp section have a predetermined number of threads and also on the basis of further infed data concerning the warp sections to be wound determines the number of revolutions of the spindle in the opposite rotational sense needed in order to displace the carriage, following completion of the winding of a warp section, back into the starting position for the winding of the next warp section. The processor upon recall emits signals which with the aid of further means initiates such return displacement of the reed carriage.

Apparatus for controlling the movements of a reed carriage during warping

An apparatus for controlling the application of warp sections during warping, wherein a winding of predetermined length of warp threads and application height should be exposed to a warping operation wherein successive threads withdrawn from the bobbins of a bobbin creel and each delivered by means of a stop motion, thread brake to a warping reed and at that location formed into a warp section upon the winding drum of a winding machine. According to the invention there are provided means for calculating at any point in time a theoretical, momentary reference-application of the wound-up warp sections on the basis of fixed data inherent to the material undergoing warping and the number of revolutions of the winding drum. Further, means serve to measure at the same point in time the actual application, and means are provided for comparison of the calculated momentary reference-application with the measured momentary actual-application at such point in time and for generating a signal in the presence of deviations, this signal bringing about a correction by adjusting the thread tension of the thread withdrawn from the creel.
