Tensioning apparatus and method for an interlaced thread

摘要

A tensioner for gripping an inserted thread in a weaving shed and applying or removing tension based on the thread's inserted tension. Through the use of sensors in a thread gripper, the inserted thread tension is compared to a desired value in a controller which controls the direction of rotation of a drive motor connected to the tensioner. A thread positioner which cooperates with the gripper assures that the threads are repeatedly gripped at the same general location. This expedites the detection of the inserted tension and avoids false initial tension readings.
