Claim 1
Independent Claim
139 words
A METHOD OF THREADING IN A YARN PROCESSING APPARATUS HAVING AT LEAST ONE YARN SUPPLY ROLLER, AT LEAST ONE YARN DRAWING ROLLER AND AT LEAST ONE TAKE-UP, SAID METHOD COMPRISING THE STEPS OF DISCONTINUING ROTATION OF SAID SUPPLY ROLLER, DRAWING ROLLER AND TAKE-UP BY DISCONNECTING THE SAME FROM THE RESPECTIVE DRIVES THEREFOR, PASSING YARN FROM A SUPPLY PACKAGE AROUND THE SUPPLY ROLLER, DRAWING ROLLER AND TAKE-UP WHILE THE SAME ARE DISCONNECTED, IMPARTING SIMULTANEOUS ROTATION TO SAID DRAWING ROLLER AND TAKE-UP BY SIMULTANEOUSLY CONNECTING THE SAME TO THE RESPECTIVE DRIVES THEREFOR WHILE PERMITTING FREE ROTATION OF THE SUPPLY ROLLER AT A SPEED SUBSTANTIALLY EQUAL TO THAT OF THE DRAWING ROLLER, REDUCING THE SPEED OF ROTATION OF SAID SUPPLY ROLLER BY CONNECTING THE SAME TO THE DRIVE THEREFOR TO COMPLETE THE THREAD-IN, WHEREUPON SUBSEQUENT OPERATION WILL PRODUCE AND COLLECT DRAWN YARN.
