Definitions

  • a segmental core element is formed of a plurality of similar part-cylindrical segments. each being a sector of a cylinder, and each sector having a central portion adapted to fit against a wind-up spindle and radially extending surrounding portions formed as an open cellular structure, preferably a hexagonal honeycomb structure.
  • the present invention relates to a holding core for yarn spools, pims, and the like, and more particularly to a core structure which can be used with a variety of pirn or spool core sleeves, or tubes, and which is adapted to be located on a wind-up spindle having a spreader arrangement.
  • Spooling machines require a large number of different Spool sleeves or core inserts which have to be matched to the length of the spooling sleeve, the form, the type of yarn or thread to be spooled, the size of the spool, and the like.
  • Each separate spool sleeve or tube on which yarn is to be wound then requires a special core body to locate this tube on the spindle; in actual operation, therefore, a large number of different types of core bodies will be used which require substantial storage space and costly investment.
  • the core bodies must meet various requirements, among which low weight, exact centricity and good bearing surfaces are some of the more important. These requirements can be met only with substantial and extensive machining.
  • the core is formed as cylindrical segments, that is, as segments of a rotary cylindrical body; each segment is of open, cellular honeycomb construction and surrounds a core portion, adapted to fit against the drive spindle.
  • a structure in accordance with the invention, permits stocking a single type of similar segmental elements of same length, so that the storage and stocking problems is reduced to stocking merely segments of different lengths. It is simple to shape the segmental elements by turning down the outer diameter, either by the manufacturer, or in the shop of the user, to match the core segments to any desired cylindrical or conical spool tube or sleeve, on which thread is to be wound.
  • the cellular structure of the portion of the core which surrounds the center thereof results in a light-weight structure, independent of later shaping, for example by turning or removal of material, while providing substantial stiffness and a large surface for the interior of the spool sleeve or tube on which the yarn is to be wound.
  • the walls of the cellular structure are hexagonal honeycomb, and so located that, within the limiting surfaces defining a sector, they extend parallel to the plane of symmetry of the respective segment.
  • FIGURE is a perspective view of the core element of the present invention.
  • Three similar segments 1, 2, 3 are so shaped that they form cylinder sectors of a body of rotation, that is, form sectors of a rotary, circular cylinder.
  • the segments surround a spindle (not shown) of a spooling machine in such a manner that the radial position of the sectors is adjustable in dependence on spreading of the spindle.
  • sleeves or tubes on which thread is to be wound, and slipped over the three rotary sectors can be radially clamped, to rotate with the spindle.
  • Such clamping and spreading arrangements and spindles are known.
  • Each one of the segments has a central portion and a surrounding open, cellular honeycomb portion.
  • the cells are preferably hexagonal shaped; some of the cell walls 4, within the limiting walls 5, 6 which form sectorlimiting surfaces, are parallel to the plane of symmetry of the respective sector.
  • the various individual cells are hexagonal; the walls 4 of the cells, the end walls 7 and 8, and the sector terminal walls 5 and 6 are all of approximately the same thickness.
  • the various honeycomb cells may extend to a depth of about to 4/5 of the radial extent of the segment.
  • the diameter of the three segmental bodies, together, is usually in the order of 10 to 15 cm; the axial length may vary widely and may extend to about /2 meter.
  • the segments are preferably made of aluminum alloy, as extrusions, or injection castings.
  • the internal shape, and elements, which are to cooperate with the spreader arrangement of the specific spindle can be cast simultaneously; these are not shown since wellknown.
  • the casting types and shapes can be simple, permit ting efficient manufacture of the segments.
  • the casting molds may be readily removed from the cast segments radially, and the castings, after having been made, usually come clean so that further working and finishing are unnecessary.
  • the open, cellular honeycomb construction of the segments results in very low weight of the entire core structure, while still providing substantial stiffness, and a large bearing surface for the sleeves or tubes to bc slipped thereover.
  • the segmental body can be clamped circularly, and turned down to any desired diameter or shape, for example to be conical. The extent of material being removed is small, and hence the loss in material, upon removal of some of the surface portion will also be small.
  • hexagonal, honeycomb shape of the cells provides a stiff, easily arranged structure from which molds can readily be removed; other shapes may, however, be used and the term honeycomb used herein is not to be deemed limited to hexagonal cells.
  • Segmental core insert to form a core element for winding bodies and to hold the winding bodies on the spooling spindles comprising a plurality of similar segments, each being a sector of a cylinder, each cylinder sector having a central portion adapted to fit against the spindle and a radially surrounding portion, said radially surrounding portion being formed as an open, cellular, honeycomb structure.
  • Core insert according to claim 1, wherein the structure is a hexagonal honeycomb structure.
