Description:
Pelmet or Tie-Back Foundation Blank Material This invention relates to pelmet or tie-back foundation blank materials.

Pelmets are made from a shaped foundation material covered with a facing material. In a conventional structure, the foundation material comprises a hessian material, the facing material being sewn thereto, sometimes with intervening upholstery padding. One substitute product, which is easier to use, and which has been on the market for some considerable time, is a pre-marked stiff plastic strip material having a depth equal to the deepest pelmet desired to be made from it, with a plurality of pelmet outlines in traditional styles printed on it. The basic shape of the pelmet can be cut out from the strip material and covered with facing material, usually, of course, the same material as the curtains for which the pelmet is intended. The strip is coated with adhesive for ready attachment of the facing material, the adhesive being covered with a peel-off protective layer. The same material is also used for making tie-backs.

The substitute product, however, does not have such a good'finish'as one made in the traditional way, being, by comparison, flat and uninteresting in appearance.

The present invention provides an improved pelmet or tie-back foundation blank material that gives a very much improved'finish', more closely resembling what is achieved by the traditional approach.

The invention comprises a pelmet or tie-back foundation blank material comprising a stiff, cuttable base strip material, comprising a layer of upholstery filling, and being marked with multiple pelmet outlines and/or grid lines as a cutting guide.

The material can also be marked with tie-back outlines.

The filling may comprise foam. A layer of foam as little as four or five millimetres thick makes a surprisingly big difference to the appearance of a made-up pelmet.

The filling and/or the side of the material opposite the filling may be covered with adhesive for attachment of a facing material., and the adhesive may be covered with a peel-off protective layer. The peel-off protective layer may bear the pelmet outline markings. The material may have markings on both sides. Different sets of designs may be printed on each side, making the task of cutting out any one design less confusing.

The filling may be adhesively attached to a backing layer.

The backing layer may comprise a stiff plastics material, as in the existing product, or a conventional hessian, or even cardboard.

In such a product, the adhesive face must be on the filling material, the release liner being applied on top of the adhesive layer. There is here a further problem, however, inasmuch as, regardless of which way the product is rolled up for presentation and sale, there is a difference in length between the inside face and the outside face of the material on the roll.

The present invention provides a solution to that further problem.

In the blank material aforementioned comprising a stiff but rollable backing layer and a filling bonded thereto, the filling have an adhesive surface for attachment of an overlaying material of choice and thereon a release liner, the whole being adapted to be rolled up for storage, presentation and sale, the release liner is corrugated, the folds of the corrugation lying parallel to the rolling-up axis.

The invention comprises also a roll of such material. The corrugated release liner may be on the outside of the roll, the corrugations being such as to enable the release liner to accommodate the degree of stretching required on account of its outside position.

The corrugated release liner, however, may be on the inside of the roll, the corrugations being such as to enable the release liner to accommodate the degree of compression required on account of its inside position.

In a simpler embodiment, the blank material is not covered with an adhesive, rather the pelmet face material is mechanically attached, as by staples, at the back.

Embodiments of pelmet or tie-back foundation blank materials according to the invention will now be described with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a first embodiment, exaggerated depthwise; Figure 2 is a view like Figure 1 of a second embodiment.

Figure 3 is a view like Figure 1 of a third embodiment; Figure 4 is a view like Figure 1 of a fourth embodiment; Figure 5 is a cutaway perspective view of a fifth embodiment; Figure 6 is an edge-on view of the embodiment of Figure 5; Figure 7 is an edge-on view, like Figure 6, of a sixth embodiment ; Figure 8 is an edge-on view, like Figure 6 of a seventh embodiment; Figure 9 is a view of a rolled-up material; and Figure 10 is an edge-on view, like Figure 6, of an eighth embodiment.

Figures 1 to 4 illustrate pelmet or tie-back foundation blank materials 11 comprising a stiff, cuttable base strip material comprising a layer 13 of foam upholstery filling and being marked with multiple pelmet and/or tie-back outlines as a cutting guide.

The foam filling 13 is covered with adhesive 14 for attachment of a facing material, usually the same material as will be used for the curtains for which the pelmet is intended, and the adhesive 14 is covered with a peel-off protective layer 15.

The filling is adhesively attached to a backing layer 12, which may be of a stiff plastics material, hessian or cardboard, or, indeed, an other suitable material. It is desirable that the material be capable of being rolled up for storage and transportation, especially from shop to home.

Figure 1 illustrates a material with filling 13 on one face, while Figure 2 illustrates a material with filling 13 on both faces. The pelmet outlines 16 can be printed on the protective layer 15, and may be printed, on one face, some with reference to one edge, some with reference to the opposite edge, to separate the cutting lines as much as possible one from another and avoid confusion in cutting out the profiles. If, as in Figure 2, profiles are printed on both faces, the markings may be even more spread out. For easier identification, the markings for different outlines may be colour-coded.

Figure 3 illustrates a material 11 which has on one face of a backing layer 12 a layer of foam filling 13, an adhesive 14 and a protective layer 15, while on the other face it has a layer of adhesive 14 and a protective layer 15. This allows face fabric to be readily attached to the back of the base material having been wrapped around from the front.

Figure 4 illustrates a material 11 which is like that a Figure 3, except that on the rear face, it has a layer of adhesive 14 holding a Velcro (RTM) loop material 16, which allows the face material to have, for wrap-around attachment at the rear of the material 11, Velcro hook panels.

Figures 3 and 4 illustrate grid lines 31 printed on the peel-off layer 15, which can be used for self-design pelmet shapes, facilitating reasonably accurate curve drawing simply by joining up selected intersections, as seen in Figure 3, or for tie-back design as seen in Figure 4.

It is preferred, if the filling is foam, that it be fire-resistant.

Various modifications can be made to the design and structures disclosed above. For example, the filling may be attached to a backing layer otherwise than adhesively, for example by stapling. And the adhesive attachment of the facing material may be a heat activatable adhesive, the facing material being ironed on, which may make it possible to dispense with the protective layer 15. The provision of adhesive or other means of attachment for the facing material on both faces of the material will facilitate the application of the facing material.

Figures 5 to 9 illustrate a pelmet blank material 11 from which a pelmet shape can be made, comprising a stiff, but rollable, substrate 12 and a filling 13 bonded thereto adapted for overlaying with a pelmet face material of choice. Usually, the material from which curtains are made will be used.

Usually, again, both faces of the blank material will be coated in adhesive for the face material, since the face material will be folded around the"back"of the blank to secure it thereto. This is also the case when a filler-a recent development-is provided. In this case, the filler is provided with an adhesive surface and a release layer.

In the drawings, at least the release liner 14 on the filling 13 side is corrugated. This enables the pelmet blank material as a whole to be rolled up for storage, presentation and sale. The folds 25 of the corrugated release liner 14 lie parallel to the rolling up axis 16 (Figure 9).

The substrate 12 comprises a stiff but rollable plastic sheet material, such as lmm thick polyether or polyester. The filling comprises an open cell, resilient foam material, eg. polyurethane.

The material 11 has markings 27 facilitating the shaping, as by cutting with shears or scissors, to one or more designs of edge profile as delineated by the markings 27.

Figure 8 shows a roll-somewhat opened our for clarity of illustration- normally, it would be tightly rolled and enfolded, eg. in a cling-film or shrink wrap material for sale in appropriate lengths. In Figure 9, the corrugated release liner 14 is disposed to the outside of the roll. This means that the release liner needs to stretch a little to accommodate the fact that the outside layer of the roll is longer than any inside layer. Not illustrated is a roll in which the corrugated release liner is disposed to the inside of the roll, which requires it to compress, lengthwise.

Using the corrugated release liner on one or both faces of the material 11 facilitates rolling-up for presentation or sale without kinking and creasing because of a failure of the release liner to accommodate length change in rolling up.

Figure 10 illustrates an embodiment in which an unbacked, but stiff, foam material 101 has an adhesive layer 102 and a release liner 103 on one face. Cover fabric 104, on converting the blank to a pelmet, is attached to the adhesive layer 102 after the release liner 103 is removed, and secured mechanically to the back as by staples 104.
