Abstract
Abstract The invention relates to a grow-mat for cultivating plants, and to the production thereof, which grow-mat comprises a layer of mineral fibres cross-linked to one another by cured binding agent and treated with hydrophilic wetting agent, characterized in that in said grow-mat the principal direction of said mineral fibres extending in said layer extends in the longest dimension of said mat, in which preferably in both upright longitudinal surfaces of the grow-mat a curing oven profile is present, and/or the layer is a primary layer and at least two of said primary layers forming a secondary layer are present in a horizontal longitudinal plane of said grow-mat.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
69 words
Grow-mat for cultivating plants, comprising a layer of mineral fibres cross-linked to one another by cured binding agent and treated with hydrophilic wetting agent, characterized in that in said grow-mat the principal direction of said mineral fibres extending in said layer extends in the longest dimension of said mat and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat.
Claim 2
Dependent Claim
69 words
Grow-mat for cultivating plants, comprising a layer of mineral fibres cross-linked to one another by cured binding agent and treated with hydrophilic wetting agent, characterized in that in said grow-mat the principal direction of said mineral fibres extending in said layer extends in the longest dimension of said mat and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat.
Claim 3
Dependent Claim
23 words
Grow-mat as claimed in claim 1, characterized in that in both upright longitudinal surfaces of the grow-mat a curing oven profile is present.
Claim 4
Dependent Claim
38 words
Grow-mat as claimed in claim 2, characterized in that the layer is a primary layer and that at least two of said primary layers forming a secondary layer are present in a horizontal longitudinal plane of said grow-mat.
Claim 5
Dependent Claim
23 words
Grow-mat as claimed in claim 3, characterized in that the number of primary layers forming a secondary layer amounts to at least 4.
Claim 6
Dependent Claim
27 words
Grow-mat as claimed in claim 4, characterized by a horizontal longitudinal surface to be directed towards the plants, said surface being provided with a pattern of grooves.
Claim 7
Dependent Claim
11 words
Grow-mat as claimed in claim 5 accommodated in a watertight envelope.
Claim 8
Dependent Claim
14 words
Grow-mat as claimed in claim 6, characterized in that the envelope consists of plastic.
Claim 9
Dependent Claim
15 words
Grow-mat as claimed in claim 7, characterized in that the envelope has a white colour.
Claim 10
Dependent Claim
24 words
Grow-mat as claimed in claim 1, characterized in that present in at least one upright longitudinal surface of said grow-mat is a curing profile.
Claim 11
Dependent Claim
126 words
Method for manufacturing a grow-mat for cultivating plants, comprising the forming of a layer of mineral fibres from fiberised mineral flakes, in which layer are included a cured binder for cross-linking of the mineral fibres in said layer and a hydrophilic wetting agent to enable wetting of said mineral fibres with water, and the cutting of said layer to a grow-mat, characterized in that said layer is cut such that the principal direction of said mineral fibres in said layer extends substantially in the direction of the longest dimension of said mat, and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat, and that the cutting pitch is substantially equal to the height of said grow-mat.
Claim 12
Dependent Claim
126 words
Method for manufacturing a grow-mat for cultivating plants, comprising the forming of a layer of mineral fibres from fiberised mineral flakes, in which layer are included a cured binder for cross-linking of the mineral fibres in said layer and a hydrophilic wetting agent to enable wetting of said mineral fibres with water, and the cutting of said layer to a grow-mat, characterized in that said layer is cut such that the principal direction of said mineral fibres in said layer extends substantially in the direction of the longest dimension of said mat, and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat, and that the cutting pitch is substantially equal to the height of said grow-mat.
Claim 13
Dependent Claim
66 words
Method as claimed in claim 10, characterized in that the fiberised mineral flakes are formed into a primary layer, that said primary layer is moved reciprocally to form a secondary layer, that binder present in said secondary layer is cured, and that the grow-mat is cut from said secondary is cured, and that the grow-mat is cut from said secondary layer transversely of its length direction.
Claim 14
Dependent Claim
39 words
Grow-mat for cultivating plants comprising a layer of mineral fibres cross-linked to one another by cured binder and treated with hydrophilic wetting agent, characterized in that said grow-mat is manufactured according to a method as claimed in claim 10.
Claim 15
Dependent Claim
39 words
Grow-mat for cultivating plants comprising a layer of mineral fibres cross-linked to one another by cured binder and treated with hydrophilic wetting agent, characterized in that said grow-mat is manufactured according to a method as claimed in claim 11.
