Definitions

  • This invention relates to improvements in and connected with rollers and is concerned more particularly with rollers for use in machinery for spinning, drawing, pressing '5 or twisting textiles, such as jute.
  • the invention has for its object the provision of rollers which can be cheaply produced and yet have a long life associated with a reliable and efficient operation during service.
  • the bearing, carrying or rolling surface of a roller is constituted by a sleeve or ring of leather which is attached to an inner sleeve or sleeves of rubber by a. vulcanization process.
  • This process is conveniently carried out in a mould which comprises suitable cooling means for preventing the high temperature involved in the vulcanization from injuring the leather.
  • the rubber sleeve which may be suitably of soft rubber, is conveniently united during the vulcanization process to an inner lining of hard material, such as fibre, ebonite orhard rubber and to an outer ring or rim of leather forming the wearing surface.
  • the hard rubber lining provides a desirable bearing for the mounting of the composite band on the roller, whilst the soft rubber forms a cushion and ensures a resilient pressure on the textile material as it is fed or drawn or carried over the leather rim.
  • the composite annular band thus formed is adapted to be removably mounted on the periphery of a supporting member, so that renewal of the band may be readily effected when required.
  • Figure 1 is a sectional elevation showing a roller in accordance with these improvements with the flange plate detached.
  • Figure 4 is an end elevation of Figure 1.
  • Figure 5 is a sideelevation of Figure 4 with the roller mounted on a shaft or spindle.
  • Figure 6 is a section on the line VIVl, Figure 7 and showing a mould for use in the production of the composite band and Figure 7 is a plan view of Figure'6, the left half being shown with parts removed.
  • the leather rim a is circularly cut out of a flat piece of leather, Figure 2.
  • This annulus of leather 1s then given a half turn inwardly so that the then uppermost side face a and undermost side face a of the annulus become the outer and inner surfaces respectively of the 0 leather rim as seen in Figure 3.
  • Theabsence of stitching increases the life of the ring as there 6 is no danger of the chafing of a sewn connection whilst the production is cheapened by the elimination of the stitching operation.
  • the leather ring a may be rubberized or impregnated with a rubber solution and 18 compressed.
  • the leather ring or band a is placed in a suitable mould b, Figures 6 and 7 together with a suitable quantity of soft rubber to form an inner sleeve 0 and finally an ebonite or hard.
  • rubber lining d is placed inside the ring of soft rubber c.
  • the various members a, c and at having been treated with suitable solutions containing curing, vulcanizing, accelerating and other ingredients, heat is applied to the mould b, in any suitable manner so that attachmentof the parts is effected by vulcanization.
  • the mould b suitably comprises circumferential cooling means such as an iron or steel ring efor the leather ring a, so that the latter is maintained at a low temperature and is not de- 9 leteriously affected by the heat of the treatment.
  • the base of the mould b is recessed at f on its upper surface to provide a matrix for receiving the cooling ring 0 and the elements a, 0 and (Z to be vulcanized.
  • the matrix is closed by an intermediate member 9 and a central core h, the rim h of which overhangs or extends over the intermediate member 9.
  • the latter and the core h. are formed with recesses i on their under surfaces so as to form a complementary part of the matrix;
  • The-core member it may. be formed with a central hole It? so that heat may be conveyed radially from the centre of mould whentheparts have been connected together. This connection may be effected byshort screw.
  • the mould parts are detached and one or more steel cooling rings 6 are inserted in the mould.
  • the leather ring a treated with any suitable solution for ensuring effective vulcanization is then inserted within the steel ring or rings 6.
  • This is followed by the application to the inner surface of the leather ring a of uncured soft rubber 0, for example in the form of a dough treated with a vulcanizing solu-' tion.
  • the hard rubber ebonite, or fibre ring d is placedwithin the soft rubber mass 0;
  • the mould 6 is thereupon closed by the application and connection of the intermediate member 9 and.
  • the heat may be applied from above or below by any suitable means such as by steam or electrically heated plates. Or the heat may be applied from. the central hole 7L2, so that heat is transmitted radially.
  • the duration of the treatment is conveniently such that the leather a is not overheated by the heat conveyed radi ally from beneath and/or the centre of the mould and in any case the leather is maintained at a low temperature by the surrounding steel ring or rings 6 so that injury to the leather due to overheating is prevented.
  • the band is mounted upon the periphery of a supporting member or wheel device is Figure 1 formed with spokes 7c, and composed wholly or partly of any suitable material, such as wood, metal or hard rubber.
  • One flange plate 10 of:therim-Zc oflthis member is may be detachable so that the band may be readily attached and removed. Consequently when a band (0,0, cl becomes worn it is necessary to discard only this worn band and to replace freshband on the supporting member la.
  • the band maybe attached to the latter. in any convenient manner.
  • the detachable plate 10 and the'band may be held in position by screw bolts Z secured to the fixed flange k ofithe supporting member 7a and passing through holesin the ebonite, hard rubber, or fibre lining d ofthe band.
  • a roller for textile machinery comprising a continuous annular leather cut and half-turned from a flat pieceof leather, and an inner sleeve of soft rubber, said rim and sleeve being united by vulcanizing under heat and pressure.
  • a roller for textile machinery comprising a composite band composed of a leather rim, an inner sleeve of soft rubber and a lining of hard material, said parts being intimately united by a vulcanization process, a wheel device, said band being mountable on the periphery of said wheel, and a detachable flange attachable to said Wheel for holding said band in. position.
  • a roller for textile machinery comprising a composite band composed of a con- 6.
  • a roller for textile machinery comprising a continuous jointless cylindrical leather rim, the outer surface of the leather from which the said rim is made comprisin one of the cylindrical surfaces, an inner s eeve of soft rubber, said. rim and sleeve being united by vulcanizing under heat and pressure.
