Patent number: 10301145Abstract: A method for unwinding yarn is provided that allows for maximizing the draft of the yarn, while monitoring tension. The method includes providing a yarn package including elastic yarn; choosing a selected draft for said elastic yarn; unwinding the elastic yarn from the yarn package from a driven roll to yarn processing equipment at the selected draft which is determined by a ratio of a speed of the yarn at the yarn processing equipment to a speed of the driven roll; measuring tension in the elastic yarn; and providing an alarm when said tension reaches a critical level.Type: GrantFiled: April 2, 2014Date of Patent: May 28, 2019Assignee: INVISTA North America S.ar.l.Inventor: Ronald D.

Publication number: 20150351972Abstract: An elastic thread transporting assembly and method provides for the transporting of thread to a production line. The assembly includes a thread creel for supplying multiple threads. The thread creel defines an unwinding location. A carrier is positioned for transporting the threads to the production line along a carrier path. An attachment device for attaching the threads to the carrier is provided. The attachment device is placed in close proximity to the unwinding location. The carrier path provides unrestricted access to the threads between the unwinding location and the production line.Type: ApplicationFiled: December 30, 2013Publication date: December 10, 2015Applicant: INVISTA NORTH AMERICA S.A.R.L.Inventor: Ronald D.

Publication number: 20080283653Abstract: A compact continuous over end take-off creel system with a tension control apparatus permits unwinding of high tack elastomeric threads from multiple thread packages. Thread tension is monitored and controlled through a variable speed motor of a driven take-off roll to maintain continuous operation of the creel system by avoiding breakage of elastomeric threads. Separate motors and thread tension sensors, optionally in combination with pretensioners, may be used for groups of threads or for individual threads.Type: ApplicationFiled: April 18, 2008Publication date: November 20, 2008Applicant: INVISTA North America SARLInventors: Ronald D.
