Abstract

An apparatus and method of robotically tying a knot that includes the steps of removing the package from the elevator tray to a knotting head apparatus at the knot-tying location where a knot is tied in a 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

Apparatuses, systems and methods include support brace(s), one or more of which are configured to support a receiver apparatus relative to a frame and define an opening that is configured to receive and orient a post along a vertical axis. A stator element coupled to one or more of the support brace(s) is rotationally fixed relative to the one or more support brace(s) about the vertical axis. A rotor element is configured to pivot about the vertical axis and includes a base and a package holder. The package holder includes a proximal end, a distal end, and an elongated body therebetween. The proximal end is coupled to base such that the elongated body extends at least partially in a radial direction relative to the vertical axis. The actuator is configured to receive an activation signal and pivot the rotor element relative to the stator element about the vertical axis.

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 yam 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 yam 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.
