Definitions

  • the invention relates to fabric reinforced wear resisting materials which are especially suitable for use in the construction of belting, hose and other flexible members which are subject to wear and tension in use (e. g. belting for the transmission of power or for use in a conveyor belt).
  • the materials may however be used for other purposes.
  • the invention provides a belt, hose or other flexible member having substantial tensile strength in one direction and of the kind comprising rubber, polyvinyl chloride or like material and a fabric reinforcement therefor, in which the fabric has the warp threads extending in the said direction, some of the warp threads have little crimp and are adapted to provide the tensile strength and others of the warp threads have substantial crimp thereby forming a ribbed structure of which the ribs afford a cover for the strengthproviding threads.
  • the preferred structure of the fabric is that alternate warp threads or ends have little and substantial crimp respectively but other arrangements are within the invention. For example there may be two warp ends woven with little 'crimp to each one with substantial crimp or one end with little crimp to each two with substantial crimp.
  • weft threads or picks lie on opposite sides, preferably alternately, of the strength-giving warp threads which have little or no crimp.
  • the crimp of the strength-giving warp threads or ends is in the region of nil to 2.5% and about 100% to 160% for the cover warp ends.
  • the crimp of the weft threads is preferably in the region of States Pat 2,793,151 Patented May 21, 1957 0.5% to 2.5%.
  • the crimp is considered as being the increase in length of a thread which has been removed from the fabric and straightened (with stretch), over the length of that thread when in the fabric, expressed as a percentage of the length in the fabric.
  • Figure 1 shows a longitudinal section through a portion of a conveyor belt
  • Figure 2 is a side view of a portion of a V belt
  • FIG. 3 is a section through the V belt
  • Figure 4 is a longitudinal section through a length of hose
  • the alternate warp threads 13 are woven under substantially less tension and accordingly have substantial crimp thereby providing, on each side of the fabric, ribs 14 which extend cross-wise of the belt.
  • the weft threads, which also extend cross-wise and from the cores of the ribs, are shown at 15.
  • Figures 2 and 3 show the application of the invention to a V belt.
  • the fabric is around the surface of the belt as shown at 17.
  • the ribs 14 and weft threads extend around the belt.
  • the fabric is of much finer structure than that employed in the previous example.
  • the construction has the advantage that the ribs provide a good gripping surface.
  • Figure 4 illustrates a hose incorporating a fabric reinforcement 20 which is according to either of the foregoing examples.
  • the fabric is covered by an inner lining tube 21 and an outer cover tube 22, both bonded to the fabric by impregnation of the fabric.
  • the fabric constitutes an outer cover layer for a hose, the grooves between the ribs being filled with rubber or plastic material.
  • the warp threads extend axially.
  • the fabric may be woven in tubular form and may be lighter than those employed for belts (e. g. between 5 oz. and 22 oz. per square yard).
  • the fabric used in carrying out the invention may be wholly or partly of rayon, Terylene, nylon, glass, wire and like materials.
  • a flexible elastomeric article comprising a woven reinforcing fabric having contoured opposing surfaces of alternating parallel ribs and grooves and including parallel substantially uncrimped tension-resistant internal strength Warp members disposed transversely to said ribs and grooves, and a flexible elastomeric cover material impregnated into and adhered to said opposing surfaces of the fabric and filling said grooves.
  • a flexible reinforced elastomeric article comprising a fabric having parallel substantially uncrimped tensionresistant strength warp members, substantially uncrimped weft members arranged on opposite sides of said strength Warp members, and highly crimped cover warp members interlaced with said weft members intermediate said strength warp members, said cover Warp members providing a surface contour for opposing sides of the fabric of alternating ribs and grooves transverse to said strength warp members, and a flexible elastomeric cover material adhered to said opposing surfaces of the fabric and filling said grooves.
  • a flat flexible belt having a reinforced carcass comprising the structure defined in claim 2, said strength warp members of said structure extending longitudinally of the belt.
  • a flexible hose having a reinforced wall comprising the structure defined in claim 2, said strength warp "members of said structure extending longitudinally of the hose.
  • a side driving belt having an external wrapper on the side-driving faces thereof formed as structurally defined in claim 2.
  • a flexible elastomeric article comprising a reinforcing fabric having parallel tension-resistant nylon warp threads having a crimp of less than about 2.5%, weft threads alternatingly arranged on opposite sides of said strength warp threads and having a crimp of less than about 2.5 and cotton cover warp threads parallel said nylon warp threads and interlaced with said weft threads intermediate said strength warp threads with a crimp in the range of about to to provide a fabric surface contour of alternating ribs and grooves transverse to said strength Warp threads, and a flexible elastomeric cover material adhered to said opposing surfaces of the fabric and filling said grooves, said material in said grooves serving as keying members to interlock said cover material with said fabric.
  • a flexible elastomeric article comprising a fabric having parallel substantially uncrimped tension-resistant nylon Warp members, substantially uncrimped weft members arranged on opposite sides of said nylon warp members, and highly crimped cotton cover warp members interlaced with said weft members intermediate said nylon warp members, said cover warp members providing a surface contour for opposing sides of the fabric of alternating ribs and grooves transverse to said nylon warp members, and flexible elastomeric material adhered to said opposing surfaces of the fabric and filling said grooves.
