Definitions

  • ABSTRACT 0F THE DISCLOSURE A warp beam used for conveying threads or yarns in textile apparatus which consists of a tubular shaft with attached circular end flanges composed of a light metal with the inner facing surfaces 'of the flanges being covered by a thin steel plate to provide resistance to abrasion by threads being conveyed on the warp beam and to impact damage.
  • the inner facing surfaces of the steel plate are preferably coated with a hard chrome layer.
  • flange inner surfaces of warp beams, sectional beams or the like must be in perfect condition in running off or conveying abrasive threads or yarns lduring textile operations.
  • flanged warp beams consist of a light metal or metal alloy, i,e. a metal with a specific gravity of less than 5, and they are usually made by being cast or drop forged.
  • the inner facing surfaces 'of the light metal flanges are always treated according to a special polishing process, because these surfaces must be extremely smooth and exhlbit a very high degree of polish, However, it has been found that these surfaces have a quite unwizhed mfluence for the thread or yarn due to the abrasive effect and are easily damaged caused by impact during transportation of the empty warp beams, so that individual warp beams must often 'be removed from operat1on for a reworking of the surfaces.
  • One object of the present invention is to provide an improved warp beam structure in textile apparatus whereby it is possible to retain the essential lightness in weight of the warp beam While fully protecting the inner surfaces of the flanges from abrasion and impact damage.
  • Another object of the invention is to substantially reduce or completely eliminate the necessity of resurfacing the inner faces of the flanges on such warp beams.
  • a very thin steel plate with a thickness of about 0.5 to 3 mm., preferably 0.8 to 2 mm., as a means of protecting the flange inner surfaces without substantially influencing the economy of weight and proper functioning of the Warp beam as achieved only by the use of a light metal.
  • the abrasion resistance of the steel surface can be best accomplished, for example, by means of a hard chrome coating.
  • a steel plate coated with a chrome layer having a thickness of 0.02 to 0.05 mm. is sufficient to avoid subsubstantially all of the difficulties which are caused by thread or yarn abrasion and especially by impact damage during transportation of the empty beam.
  • the thickness of the steel plate with or Without the chrome surface coating be kept as small as possible to avoid an excessive total weight of the warp beam.
  • the ratio by weight of the steel plate to the warp beam composed of a light metal must be maintained below a value of 1:15 to 1:10 depending from the warp beam size and length.
  • any number of techniques can be used.
  • the use of conventional metal-to-metal adhesives has proven to be most effective for adherence of the steel plate to the flange.
  • it is also possible to stiffen the steel plate by ending and fitting it into corresponding grooves, bores or recesses in the light metal flange and then strongly fastening the plate to the flange by means of adhesives, soldering or Welding or by means of suitably placed bolts which do not interfere with the smooth inner surface of the protective plate.
  • FIG. 1 is a cross-sectional view through the longitudinal axis of the warp beam constructed in accordance with one embodiment of the present invention
  • FIG. la is a magnified section of one of the flanges shown in FIG. 1 so as to illustrate the presence of a hard chrome coating on the steel plate attached to the flange;
  • FIGS. 2, 3 and 4 illustrate various other embodiments for attaching the steel plate to the flange on the warp beam.
  • the warp beam constructed in accordance with this invention consists first of all of the conventional structure of a central tubular shaft or spindle 1 and the opposing end flanges 2 which are connected with the shaft and are circular in shape so as to be mounted concentrically around the longitudinal axis of the shaft, for example by means of screw threads located at 3.
  • other conventional means can also be employed for attaching and fastening the end flanges to the shaft.
  • the inner side or face of each of the anges is covered with a circular ring-shaped steel plate 5, which is preferably coated on its inner surface with a hard chrome layer C as indicated in FIG. la.
  • the steel plate is most advantageously attached to the light metal flange by means of a convenitonal metal adhesive A as shown in FIG. la, and in this case the inner diameter 6 of the steel plate 5 extends up to the hub of the ange 2, while the outer diameter of this steel plate is slightly smaller or bevelled inwardly from the outer periphery 4 of the ange 2.
  • FIG. 2 Another embodiment of the steel lining or protective plate is shown in FIG. 2 which generally corresponds with respect to its arrangement and inner diameter with the steel plate of FIG. 1.
  • the outer rim 8 of the circular steel disk or plate is bent outwardly to lit over the outer periphery 4 of the flange 2.
  • the steel plate can also be suitably fastened to the light metal flange with a known metal adhesive, but on account of the reinforcing or stitfening effect provided by the rim 8, it is also possible to tightly screw the plate 7 by means of one or more suitable bolts 9 (shown in dotted lines) which are preferably strongly fastened on the outer or supporting side of the steel plate.
  • a steel inner lining can rst be bolted to the flange and a second face plate made of steel adhered thereto.
  • FIG. 3 A further embodiment is shown in FIG. 3, and in this case a circular portion on the inner face of the ange 2 has been cut away to form a circular recessed portion 13 with a depth corresponding to the thickness of the steel plate 10 which is then securely fastened in this recessed portion.
  • the inner diameter of the circular steel disk o1' annular ring plate 10 is somewhat greater than the outer diameter of the warp beam shaft 1, preferably about to 20 mm. greater in diameter.
  • the outer diameter of the steel plate or ring is preferably about to 50 mm. smaller than the outer diameter of the flange.
  • FIG. 4 Still another embodiment similar to that shown in FIG. 3 is illustrated in FIG. 4.
  • the circular steel plate 16 is similar in its dimensions to the plate 10 of FIG. 3, but an outwardly bent rim 14 and 15 is provided around the inner and outer diameters of the plate, respectively. These rims 14 and 15 fit into corresponding annular grooves recessed into the inner facing surface of the flange.
  • the plate can also be threaded or tted onto the hub of the flange, e.g. by decreasing the diameter of the hub by an amount corresponding to a two-fold thickness of the plate and then providing a corresponding protuberance in the form of a sleeve or hub-like rim at the inner diameter of the plate so as to t into the resulting recessed portion of the shaft which is normally extended by the hub of the ange.
  • This inwardly projecting protuberance, sleeve or hub-like rim of the steel plate can be extended up to the point where it would join the shaft 1 at the edge 3 which previously contacted the hub of the flange. Also, this protuberance or sleeve can be threaded on its inner diameter to engage with corresponding threads on the hub of the flange.
  • the construction of the warp beam in accordance with this invention permits considerable economies to be effected in carrying out textile operations continuously over a long period of time without any need for resurfacing the inner faces of the flanges or even replacing the protective steel plates.
  • the warp beams function in a satisfactory manner even with the addition of these steel plates, and the damage caused by impact forces is reduced substantially as well as the possible damage which might otherwise be caused by abrasion.
  • a warp beam consisting of a tubular shaft and two oppositely disposed circular anges attached concentrically at either end of said shaft, said shaft and flanges being composed of a light metal having a specific gravity of less than 5, a thin steel plate having a thickness of 0.5 to 3 mm. and a tensile strength of at least kg./mm.2 connected to and covering the inner opposing faces of said anges which are normally in running contact with thread conveyed thereover, and a hard chrome layer of a thickness of 0.02 to 0.5 mm. coated onto the inwardly facing surface of each steel plate.
  • a warp beam in textile apparatus as claimed in claim 1 wherein said steel plate is in the shape of a flat, circular, ring-shaped disk having an inner diameter which is 5 to 20 mm. larger than the outer diameter of said shaft and also having an outer diameter which is 10 to 50 mm. smaller than the flange outer diameter, and said plate is mounted in a recessed portion of the inner face of each of said flanges so as to be flush with said inner faces.
  • a warp beam in textile apparatus as claimed in claim 1 wherein said steel plate is connected to said ange by means of a metal-to-metal adhesive.
