ABSTRACT:
A twisting apparatus for light and heavy yarns has a conventional twister wherein the yarn packages are supported rotatably on a rotating flyer but is inhibited from rotation by magnets on the yarn-package holder and upright walls surrounding the yarn-package holder. The flyer is rotated at high speed so as to form a yarn balloon around the yarn-package. The walls surrounding the yarn-package holder form a square at their tops and a circle at their bottoms. When heavy-gauge yarns are being twisted an insert in the form of a cylindrical sleeve is fitted within the device to limit the balloon size. An elastomeric ring surrounding the lower portion of the outside of this sleeve is snugly engageable with the frustoconical lower surface of the interior of the surrounding walls so as to hold the sleeve centered in the apparatus.
