Definitions

  • the conventional flat for use on a carding machine is clothed with flexible foundation type card-clothing, and the strip of flexible foundation type card-clothing which is applied to the flat is called the "top".
  • metallic-wire type card-clothing in which the teeth are formed in one edge of a strip of steel wire, has been used to provide the "top” for flats.
  • metallic-wire type card-clothing it is necessary to arrange short strips of the wire in a side-by-side array and then to secure that array to the flat, so that each metallic-wire strip extends transversely of the flat.
  • the array of card-clothing which is shown in United States Specification 4 221 023 never exists as a product separate from the complete assembly or "top".
  • the individual wire strips have to be assembled on the rigid base strip and secured to it by the longitudinal brackets, so that the card-clothing array only exists when formed into the rigid assembly.
  • the HENDERSON product can only be made in limited lengths and in practice, it is made in lengths equivalent to the lengths of standard flats. Hence, the product has to be purchased by the user in preformed lengths, suited to the size of his carding machines.
  • the present invention provides a card-clothing assembly and a method of assembling card-clothing strips into the assembly, which is suitable for use as "top", the method being extremely simple and providing a card-clothing strip assembly which is readily manipulable.
  • the invention also includes carding machine components fitted with such a card-clothing assembly. Whilst the assembly is especially useful for the clothing of flats, it is to be understood that it is not restricted to this particular application of the card-clothing.
  • a card-clothing assembly which comprises a plurality of strips of metallic-wire type card-clothing arranged in a side-by-side array, with a longitudinally extending spine applied to at least one surface of the said array is characterised in that the spine comprises a flexible tape which holds the strips in the array and prevents any substantial separation of the strips from each other in the longitudinal direction of the array, or any substantial movement of the strips relatively to each other in the lateral direction parallel to the lengths of the strips, but which is substantially completely compliant in the direction normal to the said lateral direction, so that the array can be coiled.
  • the flexibility of the spine is such that the card-clothing assembly is completely lank and pliable in the longitudinal direction; that is to say, if the assembly is supported at a single point along its length, it will collapse on both sides of that point as would, for example, a wristlet watch chain.
  • This is in complete contrast to the metallic-wire type card-clothing "top" as described in U.S. Specification 4 221 023, which is made as rigid as practicable in the longitudinal direction.
  • the spine is capable of being peeled off the array of card-clothing strips. It is further preferred that the width of the spine does not exceed the width of the card-clothing array. It is also preferred that the spine comprises a tape having a self-adhesive surface.
  • the tape may comprise a self-adhesive plastics film such as that used for packaging; but it is preferred to use a tape which is coated with a more powerful adhesive than that supplied for domestic and office use.
  • This tape is well adapted to adhesion to the relatively flat surface formed by the bases of the ribs of the card-clothing strips.
  • the adhesive tape is of course, highly flexible, and if this method of forming the assembly is used, then the assembly has a flexibility in the longitudinal sense similar to that of a wristlet watch chain. In fact, the card-clothing assembly produced by this method will drape.
  • thermo-plastic (hot melt) material is applied to the surface of the card-clothing array and allowed to set to form a plastics "tape" on the array.
  • thermo-plastic material is correctly chosen, it will form a "tape” which has flexibility and which can be peeled off the array when required.
  • This method can be used to provide a "tape” on the obverse surface of the array (additional to the flexible spine) and in that case the teeth of the card-clothing become embedded in the thermo-plastic material.
  • a flexible tape additional to the spine is impaled on the teeth of the card-clothing array to an extent that the individual wire strips are secured to the tape by frictional engagement of the teeth of each strip with the tape.
  • a method of forming a card-clothing assembly in accordance with the first aspect which comprises a plurality of strips of metallic-wire type card-clothing arranged in a side-by-side array on a spine, is characterised in that the strips are accumulated in a side-by-side array and a flexible tape spine having an adhesive surface is brought into a longitudinally progressing adhesive contact with the array to effect adhesion of the spine to the array along the length of the array.
  • the strips are supported and the array is fed in a sideways direction, and at the same time, the array and the flexible spine are brought together, without relative movement between them in the said sideways direction, and caused to adhere to each other.
  • the flexible spine is applied to the array in a manner which will allow the spine to be subsequently peeled off the array.
  • thermo-plastic tape is applied to the array in the molten state and allowed to set.
  • the invention also includes a carding or like machine element (e.g. a flat or a roller) having applied thereto a card-clothing assembly in accordance with the first aspect of the invention or made by the method of the second aspect of the invention.
  • a carding or like machine element e.g. a flat or a roller
  • apparatus for forming a card-clothing assembly by the method of the second aspect of the invention comprises:
  • FIG. 1 there is illustrated a method of forming a card-clothing assembly for use as the "top” to be applied to a flat of a revolving flat type carding machine. Since revolving flat type carding machines are very well known, and since the flat itself may be of conventional construction, there is no necessity to describe the carding machine or the flat.
  • the “top” is constituted by a series of short strips 10a, 10b, 10c, 10d, ... which are cut from a long length of metallic-wire type card-clothing, and assembled on the cutting machine in an abutting side-by-side array as illustrated in Figure 1.
  • Metallic-wire type card-clothing is in itself well known, but it is necessary to mention for present purposes, that the wire has the general cross- section illustrated in Figure 1, providing a tapered and relatively narrow upper portion 12 in which the teeth are formed, and a wider rib portion 14, which ensures the spacing of the rows of teeth provided by the strips 10a, 10b, 10c, ....
  • the assembly of the metallic-wire type strips 10 is carried out in a jig so that in addition to the abutting relationship, the bases of the ribs of the card-clothing strips together form a continuous flat reverse surface 11.
  • the assembly of the strips continues until the length of the array is sufficient to extend along the effective length of the flat to which the "top" is to be applied. It will be appreciated, that the length of the array is the sum of the thickness of the rib portions 14 of the strips 10, and that the width of the "top" is equal to the length of the individual strips 10.
  • the obverse surface indicated at 15 in Figure 1 is constituted by the tips of all the teeth formed in the strips 10 which constitute the array, and there is a flat reverse surface 11 constituted by the bases of the rib portions 14 of the array.
  • each strip is cut from the stock of wire being fed into the machine, it is moved in a longitudinal direction indicated by the arrow A in Figure 1, so that the array is accumulated by moving to the right as seen in Figure 1.
  • the longitudinal direction indicated by the arrow A is of course at right angles to the length of the stock where it is being fed to the cutting station.
  • a tape 18 supplied in the direction of the arrow B from a stock (not shown) is applied to the reverse surface of the card-clothing array whilst the array is being constituted by feeding the strips of wire longitudinally of the machine.
  • the tape 18 is made of plastics film, and is similar to the self-adhesive tape which is used for packaging purposes. However, in this method, a tape is used, which is coated with an adhesive more powerful than that normally used for domestic and office purposes.
  • the end 20 of the tape 18 is secured to the reverse surface at the right hand end of the array by pressing its adhesive surface into engagement with the reverse surface 11, and then, as the array traverses in the direction of the arrow A, further tape 18 is fed from the stock, and is pressed on to the reverse surface of the array by a pressure roller 22.
  • the tape 18 thereby becomes secured to each of the strips on the reverse surface.
  • the tape 18 is of approximately the same width-as the card-clothing array as indicated in Figure 2, but this is not essential. However, the tape should preferably not be wider than the card-clothing array.
  • an assembly constituted by the array of strips 10 of metallic-wire type card-clothing, held together in side-by-side arrangement, by a spine comprising the tape 18.
  • This assembly can be removed from the machine, and of course, the individual metallic-wire strips are retained in the assembly, which is readily manipulable, and which can be secured by clips or by use of an adhesive to the flat.
  • the spine comprising the tape 18 is flexible, the assembly itself is flexible, and can in fact be coiled up if required for transporting and fitting. The flexibility of the assembly is similar to that of a wristlet watch chain.
  • the "top” assembly provided by the method illustrated in Figure 1 and 2, constitutes a new article, since hitherto, there has not existed an assembly of metallic-wire type card-clothing strips, of a flexible nature. This is because all the prior art methods of forming a card-clothing assembly having involved the provision of a relatively rigid "spine". It will also be appreciated that the method of securing the strips together by use of the self-adhesive tape 18 is extremely economical both as regards the material which is used, and the operation required to apply the tape to the strips of card-clothing wire. However, a distinguishing feature of the assembly is the fact that the adhesive tape can be peeled off the card-clothing array if required.
  • FIG 3 there is illustrated a method of securing an array of strips of card-clothing wire 10 together in side-by-side arrangement which can be used to supplement the method described above with reference to Figures 1 and 2.
  • the card-clothing wire strips are themselves constituted in the same manner as described above with reference to Figure 1, and the cutting off and assembly of the strips into an array and the fitting of the spine is also the same.
  • a "tape" 24 of hot melt plastics material is extruded on the obverse face 16 of the card-clothing array, so that some of the teeth 12 of each card-clothing strip 10 become embedded in the "tape" 24.
  • the extruded hot melt "tape” becomes sufficiently set, it is secured to each of the strips 10 with which it has engagement, by the fact that the tips of the teeth are embedded in the plastics material.
  • the hot melt plastics "tape” 24 may itself be flexible, and in any case, it assists in holding the strips of card-clothing wire in the required side-by-side array. However, the "tape” 24 can be peeled off the teeth of the card-clothing array, once the completed "top” has been secured to the flat on which it is to be used. Thus, in effect, there are two spines, one provided by the self-adhesive tape 18 on the reverse surface 11, and the other provided by the hot melt "tape” 24 on the obverse surface 15, of the card-clothing array. It will be appreciated, that when this combination method is used, the metal strips 10 are more securely fastened to each other, and it is possible to remove either of the two spines, without permitting the array to collapse.
  • FIG 4 there is shown a somewhat different method of forming a card-clothing assembly suitable for use for example, as card-clothing "top”.
  • a card-clothing assembly suitable for use for example, as card-clothing "top”.
  • short strips 10 of metallic-wire type card-clothing assembled on a machine into an array held together by a flexible spine as described with reference to Figures 1 and 2.
  • each strip 10 is formed with a rectangular notch 26 in each end of its rib portion 14, andthese notches form continuous grooves along the front and rear edges of the array of card-clothing wire strips.
  • a strip of hot melt plastics material 28 is extruded and pressed into each of the grooves formed by the notches 26, and the grooves are substantially filled by these plastics strips. Now since the strips of plastics engage with all the strips 10 and extend throughout the length of the array, they provide additional spines which have a similar effect-to the spines provided by the "tapes" described with reference to Figure 3.
  • the hot melt plastics strip 28 can be peeled away from the card-clothing array if required, but in view of their containment within the contours of the array, this may not be necessary.
  • notches formed in the ribs 14 from the base or underside and filled with a hot melt plastics strip there could be notches formed in the ribs 14 from the base or underside and filled with a hot melt plastics strip.
  • the notches could be replaced or supplemented by holes formed through the ribs 14 and aligned to form a continuous hole, with the plastics material embedded therein.
  • it is not essential to have two sets of notches forming two longitudinal grooves. In some instances, it might be sufficient to have only a single longitudinal groove, particularly if this is formed in the bases of the ribs of the card-clothing strips.
  • the invention is employed to produce "tops" for the use on the flats of a revolving flat type carding machine. It will be understood however, that the method could be used to provide "top” for stationary flats, and even for stationary flats of the kind which are curved to the curvature of the cylinder of the carding machine. Indeed, the method could be employed to provide metallic-wire type card-clothing strips, which could then be secured to rollers of carding or like machines. A possible application of such strips is on a comber half lap roller of a cotton combing machine.
