  • Patent number: 4039159
    Abstract: A cone holder for textile machines such as shuttleless looms for supporting a weft yarn supply package having a spindle member with a hub element fixed thereon. A resilient cap member having a plurality of circumferential deformable projections is carried by the hub with the projections being disposed so as to engage the inner surface of a cone for holding the latter on the spindle. A centering collar slidably carried on the spindle is biased by a spring element in a direction to cause the centering collar to engage another area of the interior surface of the cone so as to maintain the latter in a centralized position on the spindle.

  • Patent number: 4023747
    Abstract: A yarn package positioning device for textile machines such as shuttleless looms for selectively locating the weft yarn package support spindle in the most advantageous location for withdrawing weft yarn from the package carried thereon during insertion of the weft into a warp shed. Additionally to facilitate and simplify replenishment of the weft supply the support spindle is mounted on the positioning device so that it can be manually pivoted between a donning and doffing position and the preselected position for withdrawing the weft from the yarn package.
