Abstract
A tube stabilizing apparatus is provided for a textile machine of the type having a plurality of independently movable tube support members, an unwinding device for unwinding textile packages and various transporting assemblies for transporting tube support members to and from the unwinding device. The unwinding device is provided with a yarn end loosening apparatus having a pair of independently movable chamber portions, the pair of chamber portions forming a gas guide chamber for encircling a yarn package during loosening of the yarn end from the yarn package. The gas guide chamber is formed with a lateral opening. The tube stabilizing apparatus includes an arm member and a member for selectively moving the arm member through the lateral opening of the gas guide chamber into contact with the tube of a yarn package to thereby apply force against the tube in a lateral direction toward an opposing member. The arm member and the opposing member stabilize the tube to minimize lateral movement of the tube.
