Definitions

  • This invention relates to a method of making a pile carpet or rug comprising a plurality of carpet sections which are joined together or attached to acommon base, and it is the aim of the invention to provide a method which can be carried out manually much easier and faster than the known methods.
  • This object has been accomplished by providing carpet sections made by pushing pile yarns into incisions in the edges of a strip of carpet backing material.
  • the insertion of the pile yarns into incisions provided for this purpose in a narrow strip of a suitable material, for
  • plastics is a very simple procedure that can be carried out rapidly and without great effort on the part of the operator.
  • the small carpet sections of which the finished carpet or rug is to be made up make it possible to adapt the carpet or rug to any requirement and also facilitate the production of patterns therein. It is a further advantage of the said method that several persons can simultaneously make carpet sections for the same carpet or rug so that the production time can be further reduced.
  • the pile yarns may be cut in advance into lengths corresponding to the desired pile height, whereby color variation in the individual strip member is made possible, but the easiest and fastest procedure is the winding of a bundle of pile yarns onto the strip and subsequently cutting the yarns in the longitudinal direction of the strip.
  • the desired height of pile can be obtained in a simple manner by means of a preferably rail-shaped spacing member extending along the upper face of the backing strip in close contact therewith, after the winding and cutting of the pile yarns the said spacing member is withdrawn.
  • the invention also comprises a strip for use in carrying out the said method, and this strip is specific in that it is provided along both side edges with a series of incisions which are dimensioned to permit one or more pile yarns to be pushed into each incision to be held securely therein.
  • strip material may conveniently be used a suitable plastics material, for instance polyethylene, which is cheap and also keeps production costs at a low level. Besides, this material exhibits a suitable degree of flexibility and elasticity which makes it easy to push the pile yarns into the incisions and secure a good hold thereon.
  • each incision By forming each incision as a hole spaced by a short distance from the side of the strip edge and communicating with the edge through a narrow slit, a precise and uniform spacing of the pile tufts is ensured, and if the incision opens as a V-shaped notch from the bottom of which the slit extends the insertion of the pile yarns will be facilitated because the said notch will act as a guide for the yarns.
  • the joining of the finished strip elements into greater carpet sections may be effected in many ways.
  • a particularly simple and yet strong joint can be obtained without increasing the cost of the strips appreciably by providing the strips along one side edge with studs between the incisions extending at right angles to the plane of the strip and along the other side edge with holes between the incisions for engagement with corresponding holes and studs of adjacent strips.
  • adjacent strips are staggered relatively to each other it is not necessary to join the strip ends, but in practice it will be an advantage to be able to produce end joints and for this purpose also the end edges of the strip are provided with respectively holes and studs. If the regions of the strip in which the holes are provided are de pressed below the level of the rest of the strip surface the joined strips will present an entirely smooth surface.
  • the strips may be joined in other ways as well.
  • a tape or snap fastener means be provided along the edges, each edge may be formed as one side of a zip fastener, or burdock closure means may be used as joining means.
  • burdock closure means may be used as joining means.
  • fasten the strips for instance sewing, gluing or welding.
  • a further possibility is to fasten the strips to each other by means of particular strip or string shaped connecting elements, by which a very compact structure can be obtained.
  • the strip may further be provided with a plurality of holes preferably disposed on the longitudinal center line and adapted to receive the studs of a spacing member.
  • the strip may be provided with yarn holding sheds on the under side.
  • FIG. ll illustrates an embodiment of a carpet backing strip according to the invention viewed from below
  • FIG. 2 the same viewed in side elevation
  • FIG. 3 presents a section along the line III-lIl in FIG. 1,
  • FIGS. 4 and 5 show a spacing rail for use in carrying out the method according to the invention, viewed respectively from the side and from the end, and
  • FIG. 6 is a schematic and perspective view of part of a strip with a spacing rail placed in position and wound with pile yarns.
  • FIGS. 7 and 8 illustrate another embodiment of the inventive carpet backing strip, the inventive carpet backing strip being provided with a zipper half on each end.
  • FIGS. 9 and It) illusuate still another embodiment of the invention wherein the inventive carpet backing strip is provided with burdock closure means at each end.
  • the strip 1 shown in FIGS. 1 3 may conveniently be of a thermoplastic material, for instance polyethylene, and be produced by moulding. Along both side edges the strip is provided with a series of incisions, each formed by a V-shaped notch 2, a circular hole 3 aligned with and spaced slightly from the bottom of the notch, and a slit 4 connecting the bottom of the notch and the hole.
  • the holes 3 serve to retain the pile yarns in the finished carpet or rug and their diameter may be for instance 3 mm.
  • the comers between the side edges of the strip and the sides of the V-shaped notch 2 are rounded.
  • the strip Adjacent to the point of the substantially triangular projections 5 defined by each pair of adjacent notches 2 in one side edge the strip is provided with a cylindrical stud 6 extending downwardly disposed at right angles to the strip face.
  • the free end of the said stud is formed as a head 7 of slightly greater diameter than the stem and of truncated configuration.
  • the length of the stem is slightly greater than the thickness of the strip, which may for instance be 1 mm.
  • the stem diameter may for instance be 2.2 mm.
  • the substantially triangular projections 5' defined between adjacent notches are depressed below the level of the body of the strip so that the under side thereof is flush with the upper face of the projections 5', as shown clearly in FIG. 3.
  • the said projections 5' are provided with holes 8 adjacent to the points and of the same diameter as the stem of the studs 6.
  • the side edge 9 of the body of the strip adjoining the depressed projection 5' is formed as a circle segment to accommodate the ends of the projections 5 of an adjacent strip.
  • the end sections 10 and 10' of the strip 1 are substantially rectangular, and one of the said sections 10 is provided with two studs 6' corresponding to the studs 6, while the other section 10', which is depressed in the same manner as the projections 5' as shown in FIG. 2, is provided with two holes 8 for receiving the studs 6' of an adjacent strip.
  • the strip 1 On the under side the strip 1 has a low, longitudinally extending central ridge 1 1 provided with spaced groups of conical studs 12 that serve to retain the portions of the pile yarns in position on the under side of the finished carped or rug.
  • the strip On the upper side opposite the ridge 1 1 the strip is provided with a longitudinal groove for guiding a spacing rail.
  • a plurality of holes 13 adapted to receive studs 21 on the lower face of the spacing rail shown in F168. 4 and 5.
  • This rail may be of plastics or metal.
  • a groove 22 extending in the entire length of the rail and the object of which will appear from the following.
  • the rail 20 is placed on the upper face of a strip 1 as indicated in FIG. 6 and its studs 21 are introduced into the holes 13 in the strip. Then the end of a bundle of yarns preferably from a ball of yarn comprising for instance five yarns is pushed into one of the end holes 3 of the strip through the pertaining notch 2 and the slit 4 with the yarn ends extending upwardly along the side of the rail 20.
  • the yarns are then carried across the under side of the strip and pushed into the end hole 3 in the other side edge of the strip to be carried upwards, across the rail 20 and downwards to the next hole 3 in the first side edge, where it is again squeezed into position, and so the operation continues until the whole assembly comprising the strip 1 and rail 20 has been wound with pile yarns, which on their way have been fixed securely into all the holes 3 of the strip.
  • An assembly wound in this manner is shown in FIG. 6, where the bundle of yarns is designated 15.
  • the pile yarns are cut by a knife introduced into the groove 22 in the upper face of the rail at one end and carried through the groove to the other end. After the cutting the rail 20 is withdrawn, and the carpet or rug element is ready for as sembly.
  • the cut yarns will be disposed in two rows of tufts and form a compact pile of great body, the height of which is determined by the height of the rail 20.
  • the second operation which is the finishing part of the production process, is performed by pressing the studs 6 of one carpet or rug element into the holes 8 of another element, the material of which is sufficiently resilient to permit the stud heads 7 to be pressed through the holes and brought into engagement with the under side of the strip so as to provide a suitable locking effect.
  • the webs may be joined together end to end by means of the end studs 6 and the end holes 8'.
  • these end studs and holes are of the same dimensions and spaced by the same distances as the side studs 6 and side holes 8, it will also be possible to attach a transverse strip to the end edges of the strips in a web. It will obviously be possible also to stagger adjacent strips relatively to each other and thus vary the color design. Projecting portions resulting from such staggering may simply be cut off to obtain a straight edge to the carpet or rug.
  • the strips 1 may be varied in many ways both with respect to material, size and shape to be adapted to the character of the desired carpet.
  • the joining means may, as already mentioned, be formed in other ways than shown in the drawing and described here; they may even be dispensed with altogether where the elements are glued or welded together. It may be desirable to apply a layer of a hardening glue to the under side of the produced carpet for fixing the pile yarns.
  • each slot communicates with the bottom of a V-shaped notch formed in the side edge of the strip.
  • a carpet piece element according to claim 1 characterized in that it is provided along one side edge with studs disposed between the incisions extending at right angles to the plane of the strip and along the other side edge with holes between the incisions for engagement with the studs of an adjacent strip.
  • a carpet piece element according to claim 3 characterized in that it is provided with studs and holes also along the end edges.
  • a carpet piece element according to claim 3 characterized in that the edge regions of the strip in which the holes are provided are displaced relatively to the level of the body of the strip.
  • a carpet piece element according to claim 1 characterized in that it is provided with pieces of longitudinally extending fastening means along the edges.
  • each strip edge is formed as one side of a zip fastener.
  • a carpet piece element according to claim 1 characterized in that the strip edges are provided with burdock closure means.
  • a carpet piece element according to claim 1 characterized in that it is further provided with a plurality of holes preferably disposed on the longitudinal center line and adapted to receive the studs of a spacing member.
