Definitions

  • ABSTRACT In a winding construction including several layers of tensile-prestressed wire or the like which runs generally continuously in the winding direction, a plurality of supportelements are included which extend across the winding direction between adjacent layers of winding.
  • windings as described above are often used in high pressure presses and similar machines so as to increase the effective strength of the elements being wound.
  • the winding usually has an oval or circular contour, the former contour existing when the winding surrounds, for example, a press stand, and the latter when it is fitted around a cylindrical high pressure vessel, suggesting for example a cylinder within which is disposed a working piston.
  • the invention is in combination with a member having a winding thereabout made up of a plurality of layers of a tensile-prestressed elongated winding member which runs generally continuously in the winding direction.
  • the improvement comprises a plurality of support elements disposed between adjacent layers of winding and extending generally across the winding direction.
  • FIG. 1 is a perspective view, in section, showing a winding incorporating the invention
  • FIG. 2 is a perspective view, partially in section, showing a winding incorporating a second embodiment of the invention.
  • FIG. 3 is a perspective view, partially in section, showing a winding incorporating a third embodiment of the invention.
  • a winding which is made by winding flat rolled wire 1 about a member 6.
  • the wire 1 making up the winding is a continuous single element which is wound about the member 6, the wire 1 being axially traversed along the member 6 to form each individual layer of winding.
  • the wire is tensile-prestressed, and runs generally continuously in the winding direction.
  • Rigidly attached to the wound member 6 on either side thereof are fastening elements (one shown at 5), being disposed on either side of the winding.
  • a support element 2 Disposed between adjacent layers of the winding is a support element 2 in the form of a friction band, which runs generally across the winding direction. The ends of the support element 2 are fixed to the fastening elements 5.
  • friction bands 2 may with advantage be spaced at substantially regular intervals in the winding direction, and may also be positioned in a manner such that all bands between adjacent layers of winding are positioned in different radial planes from the band between preceding adjacent layers of winding.
  • the fastening elements 5 may be eliminated, and the position of each band 2 will be fixed by pressure exerted on that band by the uppermost of the pair of layers between which that friction band 2 is placed.
  • the fastening elements are substantially U-shaped in cross-section.
  • Each fastening element 5 fixed thereto within the U-shaped cross-section at least one rod 3.
  • Each support element or band 2 has loops formed at its ends, and each loop is disposed about a rod 3 as shown.
  • Each loop defines an aperture, and is secured to a rod 3 by means of a bolt 4 disposed through the aperture in the loop and threadably engaged with a bore in the rod 3.
  • FIG. 3 shows yet another embodiment of the invention, wherein each of the support elements or bands 2 are joined together outwardly of the winding itself.
  • the bands 2 actually take the form of a continuous element bent back and forth as the elements of the winding are applied. It will be seen that the fastening elements 5 in either form as shown are not needed in this embodiment.
  • the improvement which comprises a plurality of support elements disposed between adjacent layers of winding extending generally across the winding direction, wherein the support elements comprise bands spaced at substantially regular intervals in the winding direction, and wherein all bands between adjacent layers of winding are positioned in different radial planes from the bands between the next preceding adjacent layers of winding.
