Abstract

Sheet material 2 for use in electrical heating apparatus, the sheet material 2 comprising a heater layer 4 which may be carbon fabric or silicon and a substrate layer 6 which supports the heater layer and which is made of a material such as paper or textile which enables the sheet material 2 to be handled for manufacture, storage and installation. The heater layer and the substrate layer 6 are stitch bonded together by a yarn or tape 8. The paper may be creped, spunbond material or web produced and the yarn a synthetic, a metallic conductive or monofilament yarn.

Description

SHEET MATERIAL FOR USE IN
ELECTRICAL HEATING APPARATUS
This invention relates to sheet material and, more especially, this invention relates to sheet material for use in electrical heating apparatus.
Known electrical heating apparatus such for example as electric fires or electric fan heaters uses filaments made of a material which becomes sufficiently hot consequent upon the application of an electric current to provide the heat required of the electrical heating apparatus. The material is often in the form of an electrical heating element which, due to the electrical resistivity of the material from which the element is made, causes the element to become sufficiently hot and provide the required heat. The known materials do not stick well to other materials. For example, silicon is a material which is able to provide the required heat, but which is well known not to stick to anything except more silicon without extreme difficulty. Known types of electrical heating apparatus are thus severely restricted in their design, and they have been so for many years.
It is an aim of the present invention to reduce the above mentioned problem.
Accordingly, in one non-limiting embodiment of the present invention there is provided sheet material for use in electrical heating apparatus, the sheet material comprising a heater layer which is made of a material which becomes sufficiently hot consequent upon the application of an electric current to provide the heat required of the electrical heating apparatus, and a substrate layer which supports the heater layer and which is made of a material which enables the sheet material to be handled for manufacture, storage and installation, and the heater layer and the substrate layer being stitch bonded together by stitching material.
The sheet material of the present invention is thus completely different in form from heating elements as used in electric fires and electric fans. The sheet material of the present invention is thus available for use in many industrial areas hitherto not possible. Also, the sheet material is able to be produced as flexible sheet material which is conveniently rolled during manufacture, for subsequent storage and installation.
The material from which the heater layer is made is preferably silicon.
Other materials may however be employed such as carbon fabric, providing they become sufficiently hot consequent upon the application of an electric current to provide the heat required of the electrical heating apparatus.
The material from which the substrate layer is made may be paper.
Any suitable and appropriate type of paper may be employed including, for example, creped paper, un-creped paper, spunbond material, or web produced paper.
Alternatively, the material from which the substrate layer is made may be a textile material. Any suitable and appropriate textile material may be employed. Materials other than paper and textile materials may be employed for the substrate layer.
The stitching material may be a yarn. The yarn may be a synthetic yarn, a metallic conductive yarn, or a monofilament yarn. Other types of yarn may be employed.
Alternatively, the stitching material may be a tape. The tape may be of any suitable and appropriate width. Stitching materials other than yarn and tape may be employed.
Preferably, the sheet material is one in which the stitch bonding is effected by stitch bonding the heater layer and the substrate layer together, with the heater layer being unrolled from a roll of sheet material of the heater layer, and the substrate layer being unrolled from a roll of sheet material of the substrate layer.
The sheet material may include electric terminal means for enabling the sheet material to be connected to a source of electricity.
The present invention also provides electrical apparatus when comprising the sheet material.
The electrical heating apparatus may be for internal use. Thus, for example, the electrical heating apparatus may be in the form of underfloor heating. The electrical heating apparatus for under floor heating may be used for going under laminate or wooden floors, or for going under carpets.
Alternatively, when the electrical apparatus is for internal use, it may be used for wall heating, roof heating, or high or low level space/room heating, depending upon requirements.
The electrical heating apparatus may alternatively be for external use.
Thus, for example, with external use, the electrical heating apparatus may be in the form of under ground heating apparatus or on top of ground heating apparatus. The under ground or on top of ground heating apparatus may be used, for example, for football pitches, rugby pitches or other sports areas.
The electrical heating apparatus for external use may also be in the form of heating for tents, mobile homes and other external places.
The electrical heating apparatus may comprise a source of electricity.
The source of electricity may be at least one of mains electricity, a battery, solar generated electricity, or wind power generated electricity.
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows sheet material being manufactured and for use in electrical heating apparatus; and Figure 2 is a plan view of one type of sheet material produced according to the process shown in Figure 1.
Referring to Figure 1, there is shown sheet material 2 for use in electrical heating apparatus. The sheet material 2 comprises a heater layer 4 which is made of a material which becomes sufficiently hot, consequent upon the application of an electric current, to provide the heat required of the electrical heating apparatus. A preferred material for the heater layer 4 is silicon or carbon fabric. The sheet material 2 also comprises a substrate layer 6 which is made of a material which enables the sheet material to be handled for manufacture, storage and installation. The heater layer 4 and the substrate layer 6 are stitch bonded together by stitching material 8.
The material from which the heater layer 4 is made is silicon. Other materials may however be employed. The material from which the substrate layer 6 is made is paper but other materials may be employed. The paper may be any other suitable and appropriate form including creped paper, un-creped paper, spunbond, or web produced paper. The stitching material 8 is a yarn. Any suitable and appropriate yarn may be employed including synthetic yarn, a metallic conductive yarn, or a monofilament yarn.
As can be appreciated from Figure 1, the stitch bonding is effected by stitch bonding the heater layer 4 and the substrate layer 6 together, with the heater layer 4 being unrolled from a roll 10 of sheet material of the heater layer 4, and the substrate layer 6 being unrolled from a roll 12 of sheet material of the substrate layer 6.
Figure 2 is a partially cut-away plan view of sheet material 2 as produced by the process shown in Figure 1. From Figure 2, it will be seen that the heater layer 4 is provided on top of a substrate layer 6. The substrate layer 6 is in the form of creped paper. The stitching material 8 extends transversely to the longitudinal direction of the heater layer 4 and the substrate layer 6. Cross direction yarns may be inserted in the product if required.
The sheet material 2 produced by the present invention may include electrical terminal means (not shown) for enabling the sheet material to be connected to a source of electricity. Any suitable and appropriate electrical terminal means may be employed. The source of electricity may be at least one of mains electricity, a battery, solar generated electricity, or a wind power generated electricity.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, in all embodiments of the invention, instead of the heater layer and the substrate layer being provided in roll form, one or both of the layers may be provided in sheet form. In all embodiments of the invention, the heater layer can be in the form of a film or a web. The sheet material of the present invention may be used in a wide variety of internal and external applications.
