Definitions

  • a hollow roller member of generally constant outside diameter has a progressively decreasing wall thickness as measured from the longitudinal roll center towards each end thereof.
  • a ring member having externally disposed, radially projecting elements is embedded within the roller body at each end thereof.
  • a roll end flange is secured to each ring.
  • Our present invention relates to a flanged roller of the type used for the winding of yarns, fabrics or the like, such as the warp booms and take-up booms of looms.
  • the general object of our present invention is to provide a roller for the purpose set forth whose wall thickness corresponds more nearly to the expected stress distribution and which therefore may be of a lighter weight than equivalent rollers of the prior art.
  • a related object is to provide a simple process for serially manufacturing such rollers in an economical manner.
  • our invention aims at providing a convenient method of molding the body of such a roller from suitable casting material (e.g. aluminum or glassfiber-reinforced synthetic resin) in a manner allowing the attachment of two disks or check plates to that body to form its end flanges.
  • suitable casting material e.g. aluminum or glassfiber-reinforced synthetic resin
  • the cast tubular body may be conveniently fitted with a pair of end flanges
  • the mold cores and/or the cavity may be grooved, ribbed or otherwise shaped to produce complementary formations on the inner or outer periphery of the roller body, e.g. for purposes of reinforcement or to facilitate the anchoring of the yarn thereto when the roller is to be used as a warp or take-up boom.
  • FIG. 1 is an axial sectional view of a flanged roller made in accordance with our present invention
  • FIG. 2 is a fractionary sectional view, drawn to a larger scale, of an end of aslightly modified roller according to our invention
  • FIG. 3 is a cross-sectional view taken on the line III- III of FIG. 1;
  • FIG. 4 is a view similar to FIG. 3, illustrating a further modification of a roller body together with a mold therefor;
  • FIG. 5 is a fragmentary top view of the roller body shown in FIG. 4;
  • FIG. 6 is an axial sectional view of another modified roller body according to the invention.
  • FIG. 7 shows, in axial section, a mold designed to produce the roller body of FIG. 6.
  • FIG. 1 we have shown a tubular roller 10 whose inner peripheral surface 11 has the shape of a double frustocone, the thickness of the body thus decreasing progressively from the center 12 toward the two ends.
  • a pair of rings 20 bearing internal threads 21 with an inner diameter equal to the largest diameter of the inner wall surface 11.
  • These threads mate with outer threads on bosses 31 of respective end disks 30 which are of substantially larger diameter than the roller body so as to form a pair of end flanges thereon.
  • the disks 30 are provided with center holes 32 for the passage of a mounting shaft not shown.
  • Roller body 10 is further provided with an array of peripherally spaced reinforcing ribs 14, see also FIG. 3, which terminate at the central ridge 12, being thus spaced from the roller axis by a distance equal to the radius of that ridge.
  • roller body 10 may be recessed at 13 to receive projecting formations 22 of rings 20, these formations being either continuous (i.e. an annular ridge) or peripherally spaced.
  • the ring 20 of FIG. 2 is positively interlocked with the roller body 10 molded therearound.
  • FIG. 2 also illustrates a detail of ring 20 designed to prevent the entry of molding material into the threads 21.
  • the ring is shown to have a shoulder 23 flush with the cylindrical terminal portion of the inner roller periphery 11, this shoulder being separated from the threads 21 by an annular groove 24.
  • FIGS. 4 and 5 show a modified roller body 10 whose peripheral wall is deformed at 18, in the vicinity of a radial plane P, to form an outer groove 15 extending longitudinally of the roller.
  • This groove is designed to accommodate an anchor bar, not shown, to which a set of warp threads may be fastened and which in turn may be temporarily attached to the roller with the aid of straps hooked into keyholes 16 as is well known per se.
  • FIG. 4 also illustrates an iron shell 40 to be used as a mold for the chill casting of roller body 10', the shell being provided with an inner peripheral rib 41 to define the groove 15.
  • the end rings 21 may in this case be formed within a. gap accommodating the rib 41.
  • rib 41 would be omitted if the mold were used to cast a roller body Without groove 15, such as the one shown in FIGS. l-3.
  • FIG. 6 shows a roller body 10" which differs from the previously described bodies by having a central partition 17 at the location of its minimum inner diameter.
  • the embodiment shown in FIG. 6 has this partition formed with an axial aperture 19 whereby the roller can be mounted on a throughgoing shaft.
  • the diameter of aperture 19 is equal to that of the center holes 32 (FIG. 1) of disks 30, thus letting the partition 17 come to rest on the mounting shaft as a supporting web.
  • the cylindrical mold shell 40 defining a cavity 42, is open at its ends to receive a pair of symmetrical frustoconically tapered cores 50, each with a cylindrical neck 51, carried on an end plate 52.
  • the rings 20 have been slipped onto the necks 51 of the respective cores which, in order to produce an internally partitioned roller body of the type shown in FIG. 6, are axially spaced apart and are traversed by a removable central rod 53 defining the aperture 19 of FIG. 6.
  • the rings 20, particularly if they consist of a material different from that of the mass which is to form the roller body, are advantageously preheated before being slipped onto the cores 50.
  • the molding material is then admitted at low pressure into the annular space between cavity wall 42 and cores 50 to form the roller body and to fuse with the hot rings 20 into a unitary structure.
  • the mold may be opened by removal of the end plates 52 to allow the cast body to be extracted.
  • roller body is to be internally ribbed, as illustrated in FIGS. 1 and 3, the cores 50 will have to be externally grooved as will be readily understood by those skilled in the art. It will also be apparent that projections on these cores, conforming to the keyholes of FIGS. 4 and 5, may be provided on the cores 50 and will be sheared off when the mold is opened.
  • roller bodies of various configurations in a single casting step, without the need for subsequent machining to form grooves, holes, or threads for the attachment of cheek plates.
  • a roller comprising:
  • tubular body having a centrally located, longitudinal bore therethrough;
  • the outer diameter of said body being substantially constant whereby the wall thickness of the body is greatest at the center and decreases toward the ends;
