Yarn transfer tail forming and controlling apparatus

Claim 1

AN IMPROVED HIGH-SPEED YARN WINDUP APPARATUS FOR FORMING YARN PACKAGES WITH TRANSFER TAILS OF ACCURATELY CONTROLLED LENGTHS ON ROTATING YARN SUPPORTS, SAID APPARATUS ADAPTED FOR USE IN COMBINATION WITH MEANS FOR TEMPORARILY COLLECTING AND DISPOSING OF A RUNNING YARN LINE AS IT IS FORWARDED FROM A YARN SOURCE, SAID APPARATUS COMPRISING, IN COMBINATION, A SUPPORTING STRUCTURE, A ROTARY DRIVE ROLL OPERATIVELY MOUNTED ON SAID STRUCTURE, AT LEAST ONE DRIVEN ROTATABLE CHUCK ELEMENT MOUNTED ON SAID STRUCTURE FOR SUPPORTING A YARN BOBBIN IN FRICTIONAL ENGAGEMENT WITH SAID DRIVE ROLL, A MOVABLE YARN TRAVERSING GUIDE MOUNTED ON SAID STRUCTURE OPERATIVELY ASSOCIATED WITH SAID DRIVE ROLL AND A BOBBIN ON SAID CHUCK ELEMENT TO FORM A YARN PACKAGE ON A MAIN PORTION OF SUCH A BOBBIN, THE ARRANGEMENT OF PARTS BEING SUCH THAT A YARN LINE PROCEEDING FROM A YARN SOURCE TO THE MEANS FOR COLLECTING AND DISPOSING OF THE YARN IS URGED TOWARD ENGAGEMENT WITH SAID TRAVERSING GUIDE, A YARN GUIDING AND DEFLECTING MEANS MOUNTED ON SAID STRUCTURE CONSTRUCTED AND ARRANGED TO ENGAGE AND HOLD A RUNNING YARN LINE CLEAR OF SAID YARN TRAVERSING GUIDE AND IN OPERATIVE ALIGNMENT WITH ANOTHER PORTION OF A BOBBIN ON SAID CHUCK, A MOVABLE YARN RELEASING MEANS MOUNTED ON SAID STRUCTURE IN COOPERATION WITH SAID YARN GUIDING AND DEFLECTING MEANS FOR MOVEMENT BETWEEN A FIRST POSITION IN WHICH SAID YARN LINE IS COOPERATIVELY, RELEASABLY ENGAGED BY THE RELEASING MEANS AND THE GUIDING AND DEFLECTING MEANS AND MAINTAINED IN ALIGNMENT WITH SAID OTHER PORTION OF SAID BOBBIN, AND A SECOND POSITION IN WHICH SAID YARN LINE IS RELEASED FOR MOVEMENT INTO ENGAGEMENT WITH SAID YARN TRAVERSING GUIDE FOR GUIDED TRAVERSED APPLICATION ON SAID MAIN PORTION OF A BOBBIN MOUNTED ON SAID ROTATABLE CHUCK, A YARN CUTTING MEANS MOUNTED ON SAID STRUCTURE POSITIONED ADJACENT A RUNNING YARN LINE FOR OPERATIVE ENGAGEMENT WITH SAID WITH WHEN SAID YARN LINE IS IN ENGAGEMENT WITH SAID GUIDING AND DEFLECTING MEANS AND A BOBBIN ON SAID CHUCK, A FLUID PRESSURE MEANS MOUNTED ON SAID STRUCTURE COOPERATING WITH SAID RELEASING MEANS FOR MAINTAINING THE RELEASING MEANS IN ITS FIRST POSITION, SAID FLUID PRESSURE MEANS ALSO COOPERATING WITH SAID CUTTING MEANS FOR OPERATING THE CUTTING MEANS TO SEVER A RUNNING YARN LINE ENGAGED WITH SAID GUIDING AND DEFLECTING MEANS AND A BOBBIN ON SAID CHUCK TO COMMENCE WINDUP OF YARN ON SAID OTHER PORTION TO FORM A TRANSFER TAIL, SAID FLUID PRESSURE MEANS COMPRISING A CONTROL MECHANISM FOR RENDERING SAID FLUID PRESSURE MEANS INOPERATIVE TO MAINTAIN SAID RELEASING MEANS IN ITS FIRST POSITION IN RESPONSE TO OPERATION OF THE CUTTING MEANS, AND A MEANS OPPOSED TO SAID FLUID PRESSURE MEANS AND SUPPORTED ON SAID STRUCTURE IN COOPERATION WITH SAID RELEASING MEANS AND OPERATIVE TO MOVE THE RELEASING MEANS TO ITS SECOND POSITION A PREDETERMINED TIME INTERVAL AFTER OPERATION OF THE CUTTING MEANS SO THAT THE YARN LINE TRANSFER TAIL LENGTH IS ACCURATELY CONTROLLED.
