Abstract
A canister-yarn tensioning assembly is adapted for controlling tension in a running yarn drawn from a yarn supply package located within an open-top canister. The canister-yarn tensioning assembly includes a cylindrical adapter configured to reside at a mouth of the open-top canister. The adapter defines an unobstructed package transfer space sufficient to allow the yarn supply package to be manually lowered through the adapter and into the canister. A pivoted support arm is carried by the adapter, and configured to pivot at a connection point located on a peripheral flange of the adapter. One or more yarn tensioners are carried by the pivoted support arm, and are movable between an operative position within the package transfer space and an inoperative package-replacement position outside of the package transfer space.
