ABSTRACT:
According to the invention, a balloon ring is supported in concentric position about each spindle on a spinning frame by a bracket supported by a mounting rod that is in turn supported on the free ends of air cylinders mounted beside and correspondingly movable with the ring rail. The pistons in the air cylinders are initially extended to support the balloon rings at a first position. That position has been determined to be in an optimum area for control of the yarn balloon during movement of the ring rail through the lower portion of its traversing motion to build the bottom half of the package. As the rail ring begins to move through the upper portion of its traversing movements and the balloon rings approach the yarn transfer guides, a limit or proximity switch is activated to retract the pistons of the air cylinders and uniformly lower the balloon rings to a second or retracted position closer to the ring rail, and positioned to control the balloon while the upper half of the package continues to build. When the package is completed and the machine goes into bear down position, the balloon ring remains retracted to permit doffing of the package.
