DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to improvements in and relating to a method and apparatus for the manufacture of carpet and to a carpet manufactured thereby. To the present time various types of carpet such as Wilton can be manufactured by various techniques in producing a commercially acceptable product.
The term "carpet" is used throughout this specification to cover all types of woven surface covering.
Presently available techniques for making woven carpet suffer from various disadvantages including the complexity of the looms. The Wilton wire loom requires for example a multiplicity of pile wires to be inserted and withdrawn leaving the pile as a hollow loop or is cut open by a bladed wire. These hollow loops also have the drawback of contributing to the flammability of the carpet in providing a source of oxygen for any flame within the pile. Existing production techniques may also tend to suffer from a certain lack of flexibility in allowing ease of change of carpet patterns.
It is thus an object of the present invention to provide an improved method and/or apparatus for the manufacture of carpet and/or an improved carpet, overcoming or at least obviating the disadvantages in methods, apparatus and/or carpets available to the present time or to at least provide the public with a useful choice.
Further objects of the invention will become apparent from the following description.
BRIEF SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a method for the production of carpet comprising weaving together warp material including pile warp material, first and second weft materials and an additional weft material such that the additional weft material is held by and partially visible through the pile warp material and contributes to the pile of the carpet, and said first, second and additional weft materials are woven in simultaneously.
According to a further aspect of the present invention, there is provided an apparatus for producing carpet comprising feeding means for feeding first and second weft material and warp material including pile warp material to a weaving means for their weaving together and wherein said feeding means includes means for feeding an additional weft material to said weaving means for weaving together with the warp material, said additional weft material to be held by and to be partially visible through the pile warp material and contributing to the pile of the carpet, and said feeding means feed the first, second and additional weft materials simultaneously.
According to a still further aspect of the present invention, there is provided a carpet comprising first and second weft material and warp material including pile warp material woven together with an additional weft material held by and partially visible through the pile warp material and that contributes to the pile of the carpet.
