warping the textile and mechanical set or reference data are fed into a processor or microprocessor 12 which is on the one hand a data carrier and store and on the other hand determines data for the warp production and this among other things makes it possible for the processor 12 to control the warp carriage movements during the warping of successive warp sections as well as the warp section tension regulation described in greater detail hereinafter data input takes place by means of an input station 13 in which the different data are selected by means of selection keys 14 or the like and established or fixed by means of push buttons 15 this inputted data being displayed in a display panel 16 and fed into the processor 12 by means of the input key 17 in particular the input station 13 also makes it possible to store the number of threads of the warp section to be warped or the warp section width thread density threads per cm and set or reference value of the warp section tension in the processor 12 the use of a processor or microprocessor for inputting desired data at warping machines is conventional and well known in this technology as for instance exemplified by the commonly assigned u s pat no 4 141 120 granted feb 27 1979 to which reference may be readily had during the operation of the warping apparatus or machine the tension of the thread field or group of threads 100 running over the measuring roller or roll 10 is constantly.
