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.
Apparatus for the control of yarn ballooning while a yarn package is being formed on a rotating spindle by a vertically traversing ring rail movable successively through the lower and upper portions of its traverse, said apparatus comprising a balloon control ring encircling the spindle, means locating the ballon control ring at a first position spaced above the ring rail, means maintaining the balloon control ring at said first position for movement with the ring rail during the lower portion of its traverse, means locating the balloon control ring at a second position closer to the ring rail as the ring rail begins the upper portion of its traverse, and means maintaining the balloon control ring at said second position for movement with the ring rail during the upper portion of its traverse.
A pneumatic system for controlling the ballooning of yarn while being wound on a plurality of rotatable spindles, a balloon control ring encircling each spindle and a vertically traversing ring rail delivering yarn to the spindles from a source of yarn while moving through the lower and upper portions of its traverse, said pneumatic system comprising a plurality of air cylinders, means attaching the air cylinders to the ring rail for movement therewith, each air cylinder including a piston having a free end extending from the air cylinder, means connecting the balloon control rings to said free ends of the pistons, a source of air, means for simultaneously delivering air to at least some of the air cylinders to extend the free ends of the pistons and their respective balloon control rings to a first position spaced above the ring rail, means for maintaining the control rings in said first position during movement of the ring rail through the lower portion of the traverse, means for simultaneously moving the free ends of the pistons and their respective balloon control rings to a second position closer to the ring rail than said first position as the ring rail begins the upper portion of the traverse, and means for maintaining the control rings in said second position during movement of the ring rail through the upper portion of its traverse.
A method of controllin the ballooning of yarn while it is being formed into packages on rotating spindles by a traversing ring rail, said method comprising the steps of:
