lease rod

The term "lease rod" refers to one of the rods used in weaving to separate and organize warp threads, forming a shed and maintaining order during the weaving process. This is a crucial step in the conversion of yarns into fabric.12

Weaving itself is a primary method of fabric production where yarns are interlaced in a specific pattern called a binding system. The earliest evidence of looms, dating back to 4400 BCE, includes representations of a two-bar loom that utilized lease rods to separate warp yarns. These rods, or "lease sticks," are essential for creating the shed, which is the opening formed in the warp through which the weft yarn is passed. The heddle, a device that further aids in forming the shed, is considered a significant advancement in loom evolution.213
