is at no time possible the control device 56 depicted in fig1 for the different motors is preferably coordinated with the computer 72 which serves as the main control device for the entire plant the warping data can be entered into this computer through an imput station 73 whereby at the same time the necessary yarn crossings can be pre programmed the screen 74 facilitates the communication between man and machine and apart from that serves as an operator guide in which the operator 70 receives instructions from the screen 74 the computer is coordinated with the thread monitors 7 on the bobbin creel 2 through the connection cables 75 as well as with the automatics 76 for introducing the cross cords which are not more closely depicted here the control device 56 can possess an operating panel which for example is depicted in fig7 different switching devices are arranged on the operating panel which the control procedures can be triggered a keyed switch secures the control device and makes possible the preselection of different types of operation the programming switches 58 to 61 and if required further programming switches likewise permit the actuation of different functions thus for example the upper yarn crossing position of the cross reed can be assumed with the push button 58 and the lower with the push button 59 the cross lay according to choice can thus be.
