Abstract: An apparatus and method of automatically moving yarn packages between yarn processing stations in a textile environment that includes the steps of providing a yarn package elevator, transporting a yarn package on the yarn package elevator from a textile machine position to a common transfer location, and holding the package in a stationary position on an elevator tray. A label is applied to a surface of the package and the elevator tray and package is moved to a knot-tying location, the package is removed from the elevator tray to a knotting head apparatus at the knot-tying location and a knot is tied in a package yarn tail of the package to secure the package tail from unraveling in subsequent package handling steps. Correct application of the knot to the yarn tail is either validated, or in the alternative, if the knot is not validated, the package is forwarded to a location for manual reworking to apply a correct knot to the yarn tail.

Abstract: A continuous process heat set tunnel for exerting a sealing force against a top sealing roll, a yarn-transporting conveyor and a bottom sealing roll. At least first and second top pneumatic lamella sealing cylinders are mounted on the sealing roll frame for exerting against the top lamella a sealing force against the roll surface of the top sealing roll, and at least first and second bottom pneumatic lamella sealing cylinders are mounted on the sealing roll frame for exerting against the bottom lamella a sealing force against the roll surface of the bottom sealing roll.
