Cop

 

in textile manufacture, a type of yarn package on spinning machines with spindles when the yarn is wound on a bobbin, tube, or the spindle itself. Its shape is conical or, less often, cylindrical; in the latter case the ends may be conical. A cop should be strong and thick and permit easy unwinding of the yarn in an axial direction.
