Definitions

  • This invention relates to card-clothing wire and particularly, although not exclusively, relates to a method of re-clothing a part of a fibre processing apparatus, an assembly and a method of manufacturing an assembly.
  • a card-clothed taker-in roller of a fibre opening apparatus has a diameter which is very much less than that of the main carding cylinder of the apparatus. Consequently, the card-clothing wire of the taker-in roller wears much more quickly than the card-clothing wire of the main carding cylinder and, therefore, may need to be renewed two or three times during the lifetime of the wire of the main carding cylinder. With modern high production cards, the consequent loss of production is costly. There is a need for taker-in wire life to be at least equal to that of the main cylinder wire.
  • taker-in rollers with worn-out coated wire have to be returned by users to the manufacturer so that they may be re-clothed with new wire which is then coated.
  • a method of re-clothing a part of a fibre processing apparatus using an assembly which comprises a length of card-clothing wire including a multiplicity of fibre engaging elements which have selected coated and non-coated surfaces, the method comprising winding wire from a support onto the part of the fibre processing apparatus in order to re-clothe said part.
  • Said support is suitably not a part of a fibre processing apparatus.
  • Said support may simply comprise a circularly cylindrical drum.
  • the diameter of said support may be in the range 30 cm to 100 cm, more preferably in the range 45 cm to 80 cm.
  • the support may have a width in the range 10 cm to 300 cm, more preferably in the range 15 cm to 250 cm.
  • Said support may be arranged to carry enough wire for more than one part of a fibre processing apparatus, for example more than one taker-in roller.
  • Said part of the fibre processing apparatus clothed in the method is preferably circularly cylindrical and may have a diameter in the range 4 cm to 60 cm, more preferably in the range 5 cm to 40 cm. Said part may have a width in the range 1.5 cm to 400 cm, more preferably in the range 90 cm to 160 cm. Said part may be an opening roller for an open-end spinning machine or a taker-in roller for a carding machine. Preferably, said part is a taker-in roller for a carding machine.
  • the method may include an initial step of removing a length of card-clothing wire from the part of the fibre processing apparatus prior to the winding of coated wire from said support.
  • an assembly for use in a method according to the first aspect comprising a length of card-clothing wire including a multiplicity of fibre engaging elements which have selected coated and non-coated surfaces, the wire being coiled around a support which is not a part of a fibre processing apparatus and being arranged to be removed therefrom for use in the method.
  • the invention according to the second aspect may include any feature described herein.
  • a method of manufacturing an assembly as described according to said second aspect comprising coiling a length of card-clothing wire having a multiplicity of fibre engaging elements around a support which is not a part of a fibre processing apparatus such that adjacent turns of the wire are juxtaposed and coating selected surfaces of the fibre engaging elements whilst leaving other surfaces thereof uncoated.
  • substantially no coating material passes between adjacent turns of the wire during coating of the wire, in view of the juxtaposition of adjacent turns of the wire.
  • no solid material is interposed between adjacent turns of the wire.
  • adjacent turns of the wire abut one another.
  • Card-clothing wire includes a base which supports a multiplicity of fibre engaging elements in the form of teeth.
  • the length of wire is suitably coiled around the support so that the base of the wire is closest to the support and the fibre engaging elements are spaced further away from the support.
  • adjacent elongate sides of the base are juxtaposed.
  • no solid material is interposed between adjacent elongate sides of the base. More preferably, adjacent elongate sides of the base abut one another so that substantially no coating material may pass between the sides during coating.
  • selected parts of said exposed surfaces of the wire are coated.
  • selected parts of the wire are preferably left uncoated.
  • the leading surface of a fibre engaging element of a length of card-clothing wire is a surface of the element which is arranged to initially contact the fibre to be processed.
  • at least part of the leading surfaces of fibre engaging elements of the wire are coated with said coating material.
  • substantially the whole area of the leading surfaces is coated with said coating material.
  • Said coating material is preferably arranged to form a distinct layer on surfaces of the wire.
  • Said coating material is preferably a wear resistant coating material.
  • Preferred coating materials include metal carbides, for example tungsten carbide; metal oxides, for example aluminium oxide and chromium oxide; and metal nitrides, for example titanium nitride.
  • the most preferred coating materials are tungsten carbide, titanium nitride and chromium oxide, with chromium oxide being especially preferred.
  • any suitable process may be used for applying said coating material to the wire.
  • Preferred processes are those in which the coating material can be directed towards selected parts of the wire, for example the leading surfaces of the fibre engaging elements of the wire.
  • the coating process involves spraying the coating onto the wire.
  • a preferred process for coating the wire is plasma arc spray coating. In this process droplets of molten coating material, for example chromium oxide, are sprayed at selected parts of the wire. On impact with the wire, the droplets are flattened and then cool by transfer of heat from the droplets to the wire.
  • Said support used in the method is preferably cylindrical and is, more preferably, circularly cylindrical.
  • the assembly 1 comprises metallic card-clothing wire 2 which has been wound on the support drum 4 and then coated with a hard coating in order to increase its durability and, therefore, extend its useful lifetime.
  • the assembly 1 may be delivered to an end user, for example a mill, who can then re-clothe taker-in rollers using the coated wire in a relatively quick and efficient manner without the need for any specialised equipment. Thus, loss of production whilst taker-in rollers are being re-clothed followed by hard coating may be minimised with consequential potential monetary savings.
  • the support drum 4 may be a wooden or metal drum having a diameter of the order of 60 cm and a width of the order of 200 cm.
  • the metallic wire 2 wound on the drum 4 may be standard carbon-steel card-clothing wire including a base 6 which carries saw-tooth shaped teeth 7.
  • the length of wire wound on the drum may be in the range 300 to 4000m.
  • the wire is deburred prior to winding on the drum 4 by suitable means, for example by mechanical brushing (burnishing) or by chemical or electrochemical treatments.
  • the wire 2 is wound around the drum 4 so that adjacent elongate sides 8 of the base 6 abut one another. When so disposed, the wire 2 may be coated using a suitable process.
  • Known coating processes include nickel-diamond coating, plasma arc spray coating and high velocity combustion coating.
  • a preferred coating process for use in the present invention is plasma arc spray coating.
  • the surface to be coated is sprayed with melted droplets of coating material.
  • Preferred coating materials include for example chromium oxide or aluminium oxide, tungsten carbide or titanium nitride coatings.
  • Coating materials are generally relatively costly and, accordingly, it is preferred to coat only selected parts of the wire, if possible.
  • One advantage of arranging the wire on the drum with sides 8 abutting is that the abutting regions of the sides 8 cannot be coated with material during the coating process. Furthermore, it is possible in certain coating processes, for example in plasma arc spray coating, to coat selected parts of the wire, whilst leaving other parts uncoated.
  • leading surfaces 10 of the teeth 7 of wire 2 are coated whilst side surfaces 12 and/or rear surface 14 and/or land 15 may be left uncoated.
  • the assembly 1 including suitably coated wire 2 may be delivered to an end user, for example a mill, for use in re-clothing a taker-in roller.
  • the re-clothing process is relatively straightforward and simply comprises winding wire 2 from drum 4 onto the taker-in roller and then securing the wire in position. No additional specialist tools or apparatus are required in order to re-clothe the taker-in roller with the coated wire.
  • the diameter of the taker-in roller may be of the order of 250 mm. It will be appreciated that the diameter of the taker-in roller is significantly less than the diameter of the drum 4 from which wire 2 is withdrawn. It might be expected that wire 2 would be put under such stress during the winding on the taker-in roller that the coating would crack or otherwise become damaged. However, this is unlikely to be the case, in view of the fact that parts of the wire that are deformed the most during the step of winding the wire on the taker-in roller are left uncoated, due to the abutment of sides 8 of the wire during the coating process. Furthermore, since, in the preferred embodiment, only the leading surface 10 is coated, there is a negligible likelihood of the coating being adversely affected.
  • the invention may be used to re-clothe any kind of relatively small diameter card-clothed roller, for example an opening roller of an open-end spinning machine.
