Canister-yarn tensioning assembly incorporating a pivoted yarn tensioner

A canister-yarn tensioning assembly adapted for controlling tension in a running yarn drawn from a yarn supply package located within an open-top canister, said canister-yarn tensioning assembly comprising:

• a cylindrical adapter configured to reside at a mouth of the open-top canister, and defining a package transfer space for inserting the yarn supply package through the adapter and into the canister;
• a repositionable cover attached by a hinge assembly at a peripheral flange of said adapter, and configured for multiplanar movement relative to the mouth of the open-top canister;
• an upstanding support arm having first and second ends, the first end being affixed to said cover;
• a yarn tensioner carried by the second end of said support arm, and wherein said cover, support arm and yarn tensioner are movable as a unit between an operative position within the package transfer space, wherein said yarn tensioner frictionally engages the running yarn drawn from the supply package, and a package-replacement position outside of the package transfer space, whereby:
• (i) upon depleting the yarn supply package, said cover is pivoted in a first plane at said hinge assembly to lift away from the package transfer space and then swivelled in a second plane at said hinge assembly to locate adjacent an outside wall of the canister, thereby moving said cover, support arm and yarn tensioner as a unit from the operative position to the package-replacement position such that a fresh yarn supply package can be freely inserted through the package transfer space and into the canister;
• and
• (ii) after inserting the fresh yarn supply package into the canister, said cover is swivelled and pivoted at said hinge assembly to return said yarn tensioner, support arm and cover back to the operative position.
