Definitions

  • the invention relates to a floor covering according to the preamble of claim 1 and a method for producing the same.
  • Floor coverings in particular carpets, with an upper-side wear layer sometimes have a soft foam backing on the underside, which can improve walking comfort.
  • Such floor coverings can be glued to a base with suitable adhesives, thereby preventing the floor covering from slipping even when it is used in the work or sports area. If such a glued-on floor covering provided with a foam back is to be removed from the substrate again, the foam back splits, which is not only disadvantageous for the further use of the floor covering, but also also requires the foam residues to be removed from the substrate (textile practice international 1981, December, pages 1321 - 1324).
  • a generic floor covering which has an upper-side wear layer, e.g. B. from a pile, a fabric, knitted fabric or the like, and has an underside, soft foam back.
  • a network or the like which is impregnated or coated with a permanently elastic adhesive is glued to the underside of the foam and is covered on its free underside by means of a removable plastic film with a detachable adhesive connection.
  • This network can be formed from a self-interrupted plastic film coated on both sides with a permanently elastic adhesive. If the closed plastic film on the underside is removed from the adhesive surface of the network, the floor covering can be glued to the substrate.
  • this floor covering can also be used in such a way that the plastic film covering the adhesive remains on the floor covering and the latter is not bonded to the substrate.
  • the non-glued carpet can slip very easily compared to the surface, since the closed covering plastic film must be adhesive to the adhesive and therefore on a smooth surface, such as. B. PVC can slide.
  • a reticular plastic film is known from CH-A-515 109.
  • This reticulated plastic film can be used as a so-called second carpet backing and can replace the previously used jute fabrics cheaply, especially because they are very dimensionally stable due to their manufacturing process and because they can then be bonded to the back of carpets under pressure even without using their thermoplasticity if they have a surface suitable for sealing, for example one made of PVC or a melt.
  • This known plastic film is thus used as a replacement for woven and knitted fabrics, the thickness and opening size being able to be varied in a simple manner by selecting the number of layers, slot length, slot spacing and slot pattern.
  • the net is used as a carrier web in floor coverings produced by needling and gluing instead of carrier fabrics, it is of several advantages in addition to its value for money, since it not only leads to an extension of the lifespan of the needles, it is non-rotting, but also due to the tempering process that occurs during shrinking remains absolutely dimensionally stable and does not allow bulging of the installed flooring to occur.
  • the object of the invention is to create a generic floor covering which, even if it is by means of a separate one Adhesive is connected to a surface, can be removed from this surface without destroying the flooring and without leaving foam residues.
  • this floor covering should also have its own adhesion, which is determined by the foam backing, in relation to certain substrate materials.
  • a film provided with regularly distributed slits, adhesive at the softening temperature and shrinkable to form openings from the slits is used as the plastic film.
  • Such a shrinkable slit film is heated to its softening temperature and brought into contact with the free back of the foam back of the floor covering when the softening temperature is reached.
  • the floor covering according to the invention therefore neither has an adhesive between the network and the foam backing nor on the free side of the network.
  • Such a floor covering can now also be arranged by means of a between the substrate and the floor covering, for. B. spreadable adhesive can be connected to the substrate.
  • the floor covering is only bonded in the area of the openings in the network, while in the area of the webs of the network the floor covering is not bonded to the substrate. If such a type of glued floor covering is now to be removed from the subsurface, the floor covering can be removed from the subsurface together with the plastic film adhering to the foam back, since the network itself is only glued to the back of the foam to which it is also removed when the floor covering is removed remains.
  • the foam back Since the foam back is only glued to the surface in a punctiform manner through the openings in the network of the plastic film, the foam back is only damaged in the area of these punctiform glue points when the floor covering is removed from the ground. While even with flooring that is not glued to a surface and has a foam backing that does not have a network described at the bottom, the foam backing is largely destroyed when the flooring is removed, if it only adheres to the surface in a punctiform manner and the foam backing in accordance with the DE-U-7 904 078 is destroyed over the entire surface if the adhesion of the network to the substrate is too great, the floor covering according to the invention can be removed without substantial damage to the foam backing even if a particularly firm bond between the foam backing and the substrate has occurred is because a part of the foam back can only be separated in a punctiform manner, namely only in the openings of the film.
  • FIG. 1 shows an adhesive film 2 provided with slots 1, individual, straight slots 1 being arranged in rows in such a way that the slots overlap from row to row.
  • the spacing of the slits 1 in a row and the spacing from row to row are in each case approximately half the length of the slit 1. If such an adhesive film 2 slit in this way is subjected to the shrinking process, then essentially the openings 3 shown in dashed lines result , between which webs 4 remain, each of which forms a honeycomb-shaped hexagon.
  • the resulting network nodes are labeled 5.
  • FIG. 2 shows how the film 2 shown slotted in FIG. 1 looks in section. After the shrinkage, there is a structure which is shown in section in FIG. 3. It can be seen that the resulting net 6 has increased considerably in thickness compared to the film 2 shown in FIG. In particular, relatively thick webs have been created, which give the net 6 a high tear resistance.
  • FIG. 4 again shows an adhesive film 2, the slots of which have a greater distance from row to row than the slots according to FIG. 1.
  • FIG. 5 shows the principle of a machine for performing the method according to the invention.
  • a slotted shrink web 11 is fed in the direction of the arrow by means of the two feed rollers 9 and 10, which is then supported by the two support rollers 12 and 13 so that there is a piece of freely hanging shrink web 11 between these two support rollers.
  • An infrared radiator 15 with a reflector 16 is attached above this piece of freely hanging shrinking web 11 and heats this freely hanging piece so far that shrinkage occurs.
  • a floor covering web 14 to which this network 11 is now to be applied is fed here below the support roller 12 in such a way that it is guided on the support roller 13, but below the network 11, which is still at a softening temperature.
  • the plastic film to be shrunk may consist of or contain a polyethylene (PE), ethylene vinyl acetate (EVA) or EVA copolymer, polypropylene (PP), polyamide (PA), polyurethane (PUR), polyester (PEST) or another suitable thermoplastic material which is in the thermoplastic state, ie at its softening temperature with which the foam back can be glued.
  • PE polyethylene
  • EVA ethylene vinyl acetate
  • PP polypropylene
  • PA polyamide
  • PUR polyurethane
  • polyester PEST
  • a polyolefin film can be used here, since it is particularly adhesive at room temperature.
  • Such a slotted film z. B. have slots with a slot length of 4 mm, a slot spacing of 2.6 mm and a spacing of the rows of slots of 1 mm, wherein the rows of slots are aligned in the longitudinal direction of the film and thus the track of the floor covering.
  • a high pressure polyethylene film of this type then receives z. B. by an infrared radiator 15 a temperature of 115 ° C, the film is guided together with the floor covering at a feed rate of 25 m / min through the device.
  • the honeycomb openings 3 shown in FIG. 7 for the network then result.
  • the total area of these openings 3 corresponds approximately to the total area of the remaining webs and network nodes, i.e. half of the back of the floor covering is formed by the network 11, while in the other, network-free half of the foam back is accessible from the outside.
  • the surface of the network 11 glued to the foam back of the floor covering 14 can also cover almost the entire rear side of the floor covering, so that, for. B. only 15 - 25% of the foam backing remains free.
  • the substrate is first coated with an adhesive, whereupon the floor covering with its side having the network 11 can then be rolled out and pressed onto this adhesive layer. If this glued-on floor covering is to be removed from the substrate again, it is pulled off together with the network from the adhesive layer, the removal being facilitated in particular when there has been no adhesion between the network and the adhesive layer.
  • the back of the foam back is reinforced by the network, so that even if this foam back is glued to the surface in a punctiform manner, further tearing of the foam back cannot happen.
  • the foam backing can also be produced cheaper, i.e. Inexpensive fillers can be added to the foam material in larger quantities than before.
  • Such a floor covering can now also be glued to a substrate by applying an adhesive to the back of the floor covering containing the network 11, which is distributed by means of a doctor blade so that this adhesive essentially only in the openings 3 of the network and thus is arranged on the foam back itself, while the free surface of the network 11 should be as adhesive-free as possible. It is thereby achieved that the amount of adhesive applied to the substrate can also be reduced in area, which not only saves adhesive material, but also less adhesive remains on the substrate after the floor covering has been removed.
  • the floor covering according to the invention is also suitable for being laid on a smooth surface without gluing, with a certain degree of adhesion then occurring in the area of the openings in the network between the foam back and the surface.
