ABSTRACT:
Apparatus for monitoring the tension of a thread in a warp beaming operation, and for selectably clamping that thread to maintain tension in the thread. A drop wire is pivotably mounted alongside a thread guide region, and a thread clamping member is located adjacent the thread guide region. The drop wire includes a thread retaining member normally positioned to keep a thread in the thread guide region, and also includes a deflecting member which pivotably displaces the drop wire assembly to permit placing a thread into the thread guide region. A substantially straight-line path for loading the inbound thread into the thread guide region thus is provided.
