Method and apparatus for the processing of undesired yarn conditions appearing at an automatic winding machine

Claim 2

METHOD FOR PROCESSING FAULTY YARN CONDITIONS APPEARING AT AUTOMATIC YARN WINDERS OF THE TYPE PROVIDED WITH A PLURALITY OF YARN WINDING LOCATIOND AND A UNIT FOR CORRECTING SUCH OCCURRING FAULTY ARN CONDITIONS, WHICH COMPRISES THE STEPS OF: SUPERVISING YARN TRAVEL AT THE INDIVIDUAL YARN WINDING LOCATIONS, UPON APPERANCE OF A FAULTY YARN CONDITION AT A GIVEN YARN WINDING LOCATION SUCH AS ABSENCE OF THE YARN AT ANY POINT BETWEEN THE DELIVERY BOBBIN AND WIND-UP BOBBIN OF SAID GIVEN YARN WINDING LOCATION ALWAYS POSITIVELY TRIGGERING AT LEAST ONE FURTHER YARN SUPERVISING ACTIVITY UPON THE YARN AT SUCH GIVEN YARN WINDING LOCATION IN RESPONSE TO THE SENSING OF SAID FAULTY YARN CONDITION IN ORDER TO DETERMINE SIGNIFICANT INFORMATION AS TO THE AMOUNT OF YARN REMAINING AT THE DELIVERY BOBBIN, OBTAINING SIGNIFICANT INFORMATION AS TO THE AMOUNT OF YARN REMAINING AT THE DELIVERY BOBBIN DUE TO SUCH FURTHER YARN SUPERVISING ACTIVITY WHEN THE YARN POSSESSES A GIVEN CONDITION WHICH IS TO BE CORRECTED BY THE UNIT AND PRIOR TO SUCH UNIT BEGINNING CORRECTION OF THE FAULTY YARN CONDITION.

Claim 3

IN COMBINATION WITH AN AUTOMATIC YARN WINDER OF THE TYPE PROVIDED WITH A PLURALITY OF YARN WINDING STATIONS, EACH HAVING A DELIVERY BOBBIN AND A WIND-UP BOBBIN AND A UNIT FOR CORRECTING FAULTY YARN CONDITIONS WHICH MAY APPEAR AT THE INDIVIDUAL YARN WINDING STATIONS, AN APPARATUS FOR PROCESSING SUCH FAULTY YARN CONDITIONS COMPRISING YARN FEELER AS WELL AS AT LEAST ONE FURTHER YARN SUPERVISING ELEMENT, SAID UNIT COOPERATING WITH SAID YARN FEELER AND YARN SUPERVISING ELEMENT FOR RESPONSE TO AN ERROR SIGNAL FROM SAID YARN FEELER DENOTING A FAULTY YARN CONDITION APPEARING AT A GIVEN YARN WINDING STATION FOR INITIATING A KNOTTING OPERATION AND A FOR RESPONSE TO AN ERROR SIGNAL FROM SAID FURTHER YARN SUPERVISING ELEMENT DENOTING A FAULTY YARN CONDITION AT SUCH GIVEN YARN WINDING STATION FOR INITIATING A DELIVERY BOBBIN EXCHANGE OPERATION WHEN SUCH UNIT AND GIVEN YARN WINDING STATION ASSUME A RELATIVE POSITION PERMITTING REMOVAL OF THE FAULTY YARN CONDITION, MEANS NORMALLY INOPERATIVE LOCATED BETWEEN SAID YARN FEELER AND SAID FURTHER YARN SUPERVISING ELEMENT FOR OPERATING SAID FURTHER YARN SUPERVISING ELEMENT TO PERFORM A CHECKING OPERATION AT THE YARN, SAID YARN FEELER WHEN DENOTING A FAULTY YARN CONDITION POSITIVELY OPERATING SAID NORMALLY INOPERATIVE MEANS TO CAUSE SAID FURTHER YARN SUPERVISING ELEMENT TO PERFORM SAID CHECKING OPERATION AT THE YARN WHENEVER SAID YARN FEELER RESPONDS TO A FAULTY YARN CONDITION AND PRIOR TO SAID GIVEN YARN WINDING STATION ARRIVING AT A POSITION TO BE SERVICED BY SAID UNIT, SAID FURTHER YARN SUPERVISING ELEMENT CARRYING OUT A YARN CHECKING OPERATION WHICH IS TRIGGERED BY SAID YARN FEELER AND WHENEVER YARN IS ABSENT AT ANY POINT BETWEEN THE DELIVERY BOBBIN AND WIND-UP BOBBIN OF SAID GIVEN YARN WINDING STATION, SIGNAL MEANS COOPERATING WITH SAID FURTHER YARN SUPERVISING ELEMENT IN ORDER TO TRANSMIT INFORMATION ABOUT THE FAULTY YARN CONDITION DETERMINED BY SAID FURTHER YARN SUPERVISING ELEMENT TO SAID UNIT.

Claim 4

IN COMBINATION WITH AN AUTOMATIC YARN WINDER OF THE TYPE PROVIDED WITH A PLURALITY OF YARN WINDING STATIONS, EACH HAVING A DELIVERY BOBBIN AND A WIND-UP BOBBIN AND A UNIT FOR CORRECTING FAULTY YARN CONDITIONS WHICH MAY APPEAR AT THE INDIVIDUAL YARN WINDING STATIONS, AN APPARATUS FOR PROCESSING SUCH FAULTY YARN CONDITIONS COMPRISING YARN FEELER AS WELL AS AT LEAST ONE FURTHER YARN SUPERVISING ELEMENT, SAID UNIT COOPERATING WITH SAID YARN FEELER AND YARN SUPERVISING ELEMENT FOR RESPONSE TO AN ERROR SIGNAL FROM SAID YARN FEELER DENOTING A FAULTY YARN CONDITION APPEARING AT A GIVEN YARN WINDING STATION FOR INITIATING A KNOTTING OPERATION AND A FOR RESPONSE TO AN ERROR SIGNAL FROM SAID FURTHER YARN SUPERVISING ELEMENT DENOTING A FAULTY YARN CONDITION AT SUCH GIVEN YARN WINDING STATION FOR INITIATING A DELIVERY BOBBIN EXCHANGE OPERATION WHEN SUCH UNIT AND GIVEN YARN WINDING STATION ASSUME A RELATIVE POSITION PERMITTING REMOVAL OF THE FAULTY YARN CONDITION, MEANS NORMALLY INOPERATIVE LOCATED BETWEEN SAID YARN FEELER AND SAID FURTHER YARN SUPERVISING ELEMENT FOR OPERATING SAID FURTHER YARN SUPERVISING ELEMENT TO PERFORM A CHECKING OPERATION AT THE YARN, SAID YARN FEELER WHEN DENOTING A FAULTY YARN CONDITION POSITIVELY OPERATING SAID NORMALLY INOPERATIVE MEANS TO CAUSE SAID FURTHER YARN SUPERVISING ELEMENT TO PERFORM SAID CHECKING OPERATION AT THE YARN WHENEVER SAID YARN FEELER RESPONDS TO A FAULTY YARN CONDITION AND PRIOR TO SAID GIVEN YARN WINDING STATION ARRIVING AT A POSITION TO BE SERVICED BY SAID UNIT, SAID FURTHER YARN SUPERVISING ELEMENT CARRYING OUT A YARN CHECKING OPERATION WHICH IS TRIGGERED BY SAID YARN FEELER AND WHENEVER YARN IS ABSENT AT ANY POINT BETWEEN THE DELIVERY BOBBIN AND WIND-UP BOBBIN OF SAID GIVEN YARN WINDING STATION, SIGNAL MEANS COOPERATING WITH SAID FURTHER YARN SUPERVISING ELEMENT IN ORDER TO TRANSMIT INFORMATION ABOUT THE FAULTY YARN CONDITION DETERMINED BY SAID FURTHER YARN SUPERVISING ELEMENT TO SAID UNIT.
