Abstract
Abstract A improved hank reeling machine having a swift structure which is adapted to collapse around its axis as a spindle coaxially extending through the swift structure is axially moved in response to movement of a hank doffing unit which is incorporated in the reeling machine, wherein an arrangement is provided to vary the axial displacement of the spindle depending upon a selected perimetrical length of the swift structure so that the axial movement of the spindle is effected at an increased efficiency in accordance with the selected perimetrical length of the swift structure.
