Abstract
Abstract A forming fabric for use in papermaking, cellulose and similar machines. The fabric consists of a first weave (1) which in position of use of the fabric faces the material to be formed, and of a second weave (4) which faces the dewatering elements. The two weaves (1, 4) are interconnected in a known manner. The second weave (4) consists of two systems of threads (5, 6) which are parallel to each other and which are positioned in superposed relationship. In addition, they are interconnected by means of athird thread system (7) the threads of which extend at right angles to the threads (6, 5) of said two systems.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A forming fabric for use in papermaking, cellulose and similar machines, said fabric comprising a first weave which in position of use of the fabric faces the material to be formed, and a second weave, which is interconnected with the first weave, characterized therein that the first weave (1) consists of a first system and a second system of threads (2, 3) which yarn systems are perpendicular to each other, said first weave being combined with the second weave (4), which second weave consists of a first system and a second system of threads (5, 6) which are parallel with each other and which are positioned essentially in superposed relationship, and of a third system of threads (8), which are perpendicular to said two systems (5, 6) and which interconnect said two systems (5, 6).
Claim 2
Dependent Claim
135 words
A forming fabric for use in papermaking, cellulose and similar machines, said fabric comprising a first weave which in position of use of the fabric faces the material to be formed, and a second weave, which is interconnected with the first weave, characterized therein that the first weave (1) consists of a first system and a second system of threads (2, 3) which yarn systems are perpendicular to each other, said first weave being combined with the second weave (4), which second weave consists of a first system and a second system of threads (5, 6) which are parallel with each other and which are positioned essentially in superposed relationship, and of a third system of threads (8), which are perpendicular to said two systems (5, 6) and which interconnect said two systems (5, 6).
Claim 3
Dependent Claim
35 words
A forming fabric as claimed in claim 1, characterized therein that the two parallel systems (5, 6) of said second weave (4) are weft threads whereas threads of the third system (7) are warp threads.
Claim 4
Dependent Claim
36 words
A forming fabric as claimed in claim 1, characterized therein that the threads (2, 3) of the first weave (1) are of smaller diameter size than the threads (5, 6, 7) of the second weave (4).
Claim 5
Dependent Claim
29 words
A forming fabric as claimed in any one of the preceding claims, characterized therein that the two weaves (1, 4) are interconnected by means of separate binder weft threads.
Claim 6
Dependent Claim
31 words
A forming fabric as claimed in any one of the claims 1 - 3, characterized therein that the two weaves (1, 4) are interconnected by means of separate binder warp threads.
Claim 7
Dependent Claim
46 words
A forming fabric as claimed in any one of claims 1 - 3, characterized therein that the two weaves (1, 4) are interconnected by interlacing some of the threads comprised in the thread systems of one of the weaves with perpendicular threads in the other weave.
