Claim 1

A SPINNING MACHINE HAVING SPINDLES, ROTATABLE GUIDES MOVING AROUND A BOBBIN AND LAYING A THREAD THEREON, A SHAFT DRIVING THE SPINDLES, A SHAFT DRIVING THE THREAD GUIDES, RAISING AND LOWERING DEVICES DISPLACING THE THREAD GUIDES RELATIVE TO THE SPINDLES, A DIFFERENTIAL CONNECTING THE SHAFT DRIVING THE SPINDLES TO THE SHAFT DRIVING THE THREAD GUIDES, FEED AND DELIVERY ROLLERS, DRIVING DEVICES FOR DRIVING THE SHAFTS OF THE RAISING AND LOWERING DEVICES, THE DIFFERENTIAL, THE FEED AND DELIVERY ROLLERS, CONTROL DEVICES FOR SAID DRIVING DEVICES, AND AN ELECTRONIC CONTROLLER FED WITH DATA AND SIGNALS DERIVED FROM ONE OR MORE OF THE MOVING PARTS OF THE EQUIPMENT WHEREBY THE DRIVING MECHANISM IS CONTROLLED BY INFORMATION FED TO THE ELECTRONIC CONTROLLER, THE IMPROVEMENT WHEREIN, SAID ELECTRONIC CONTROLLER COMPRISES: (A) A FIRST MEANS FOR PRODUCING ORDER SIGNALS, CONNECTIONS BEING PROVIDED BETWEEN SAID MEANS AND SAID CONTROL DEVICES CONTROLLING INDIVIDUAL DRIVING DEVICES OF SAID FEED AND DELIVERY ROLLERS, AND SAID RAISING AND LOWERING DEVICES; (B) A SECOND MEANS FOR PRODUCING A SIGNAL WHICH IS PROPORTIONAL TO THE LINEAR WINDING SPEED; (C) A FIRST SPEEDOMETER DEVICE MEASURING THE VELOCITY OF SAID SHAFT DRIVING SAID GUIDES AND CONNECTED TO SAID SHAFT AND TO SAID SECOND MEANS; (D) A THIRD MEANS PRODUCING A SIGNAL MODIFIED IN ACCORDANCE WITH A DESIRED RATE OF TWIST AND CONNECTED TO SAID SECOND MEANS AND SAID CONTROL DEVICE CONTROLLING SAID DRIVING DEVICE FOR SAID DELIVERY ROLLER; (E) A SECOND SPEEDOMETER DEVICE MEASURING THE VELOCITY OF SAID DELIVERY ROLLER AND CONNECTED TO SAID CONTROL DEVICE ASSOCIATED WITH SAID DELIVERY ROLLER; (F) A FOURTH MEANS CONVERTING THE SIGNAL RECEIVED FROM SAID SECOND SPEEDOMETER DEVICE TO A SIGNAL MODIFIED IN ACCORDANCE WITH THE DRAWING RATE DESIRED BETWEEN SAID FEED AND DELIVERY ROLLERS AND CONNECTED TO SAID SECOND SPEEDOMETER DEVICE AND SAID CONTROL DEVICE CONTROLLING SAID DRIVING DEVICE OF SAID FEED ROLLER; (G) A THIRD SPEEDOMETER DEVICE MEASURING THE VELOCITY OF SAID FEED ROLLER AND CONNECTED TO SAID CONTROL DEVICE FOR CONTROLLING SAID DRIVING DEVICE OF SAID FEED ROLLER; (H) A FUNCTIONAL INTEGRATOR-GENERATOR DEVICE TRANSFORMING SAID SIGNAL PROPORTIONAL TO THE LINEAR WINDING SPEED TO A SIGNAL REPRESENTING THE POSITION OF THE THREAD RELATIVE TO THE START OF THE FIRST LAYER, AND CONNECTED TO SAID SECOND MEANS AND SAID CONTROL DEVICES FOR SAID RAISING AND LOWERING DEVICES; (I) A FIRST AND A SECOND POSITION-MEASURING DEVICE ASSOCIATED WITH SAID RAISING AND LOWERING DEVICES AND CONNECTED TO SAID CONTROL DEVICES FOR SAID RAISING AND SAID LOWERING DEVICE, RESPECTIVELY; (J) A DETECTOR FOR DETECTING THE HEIGHT LIMIT OF A LAYER SUPPLYING A CONTROL PULSE WHEN THE HEIGHT LIMIT OF A LAYER HAS BEEN REACHED, AND CONNECTED TO SAID INTEGRATOR-GENERATOR DEVICE; (K) A MULTIPLYING DEVICE, ASSOCIATED WITH SAID FUNCTIONAL INTEGRATOR-GENERATOR DEVICE AND CONNECTED TO SAID DETECTOR AND RESPONSIVE TO THE CONTROL PULSE FOR TAKING INTO CONSIDERATION THE DIRECTION OF DISPLACEMENT OF SAID RAISING AND LOWERING DEVICES; (L) AN INTEGRATOR CONNECTED TO SAID DETECTOR AND SUPPLYING CONTROL PULSES WHEN THE HEIGHT LIMIT OF A LAYER HAS BEEN ATTAINED; SAID INTEGRATOR SUPPLYING AN OUTPUT SIGNAL PROPORTIONAL TO THE NUMBER OF LAYERS OF THREAD WOUND ON THE BOBBIN DURING THE FORMATION THEREOF; (M) A TRIPPING DEVICE FOR TRIPPING A CONTROL SIGNAL AS SOON AS THE OUTPUT SIGNAL OF SAID INTEGRATOR ATTAINS A PREDETERMINED VALUE AND CONNECTED TO SAID INTEGRATOR; (N) A DEVICE PERMITTING THE MODIFICATION OF THE HEIGHT LIMIT OF THE LAYERS DEFINED BY SAID DETECTOR AND CONNECTED TO AND FED BY SAID OUTPUT SIGNAL OF SAID INTEGRATOR; (O) A SIGNAL FEEDING DEVICE THE OUTPUT OF WHICH IS CONNECTED TO SAID CONTROL DEVICES OF THE RAISING AND LOWERING DEVICES AND CONNECTED TO SAID INTEGRATORGENERATOR DEVICE AND SAID INTEGRATOR OF THE NUMBER OF LAYERS; (P) A FUNCTION GENERATOR CONNECTED TO A VELOCITY MEASURING DEVICE LOCATED ON SAID SHAFT DRIVING A DIFFERENTIAL CROWN WHEEL BETWEEN SAID DRIVES OF SAID GUIDE AND SAID SPINDLE; SAID FUNCTION GENERATOR AND SAID FUNCTIONAL INTEGRATOR-GENERATOR DEVICE ALSO BEING CONNECTED TO SAID CONTROL DEVICE OF SAID DRIVING DEVICE OF THE SHAFT OF SAID CROWN WHEEL; (Q) AN AUXILIARY MODIFYING DEVICE IN SERIES WITH SAID INTEGRATOR-GENERATOR DEVICE, PERMITTING THE TAKING INTO CONSIDERATION OF THE DIFFERENCES BETWEEN THE THEORETICAL AND TRUE SPINNING CONDITIONS.
