Abstract
Abstract An endless belt for the extended nip press of the press part in the papermaking process, wherein the endless belt is composed of a base fabric (4) and a layer of an elastic material (3) coated on one side thereof, the base fabric (4) being a warp multitude layer fabric which is made endless by hollow weaving, and the exposed side (2) of the base fabric (4) having such a structure that the plane (Q) formed by connecting the apexes of the winding of the yarns in the belt running direction (a) is at a lower position than the plane (P) by connection the apexes of the winding of the yarns in the direction (0) transversely across the belt running direction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
An endless belt (1) composed of a base fabric (4) and a layer of an elastic material (3) covering one side of the base fabric (4), characterized in that the base fabric (4) is of endless and hollow multiple layer weave, with the uncovered side (2) thereof having such a structure that the plane (Q) formed by connecting the apexes of the winding of the yarns in the belt running direction (a) is at a lower position than the plane (P) formed by connecting the apexes of the winding of the yarns in the direction (β) transversely across the belt running direction (a).
Claim 2
Dependent Claim
103 words
An endless belt (1) composed of a base fabric (4) and a layer of an elastic material (3) covering one side of the base fabric (4), characterized in that the base fabric (4) is of endless and hollow multiple layer weave, with the uncovered side (2) thereof having such a structure that the plane (Q) formed by connecting the apexes of the winding of the yarns in the belt running direction (a) is at a lower position than the plane (P) formed by connecting the apexes of the winding of the yarns in the direction (β) transversely across the belt running direction (a).
Claim 3
Dependent Claim
66 words
An endless belt according to Claim 1 wherein the distance (H) between the plane (Q) which is in contact with the apexes of the winding of the yarns in the belt running direction (a) and the plane (P) which is in contact with the apexes of the winding of the yarns in the directions (B) transversely across the belt running direction is 0.11 to 0.33 mm.
Claim 4
Dependent Claim
38 words
An endless belt according to Claim 1 or Claim 2 wherein the multiple layer weave of the base fabric is triple layer weave in which the yarns in the belt running direction (a) are disposed in three layers.
Claim 5
Dependent Claim
116 words
An endless belt according to Claim 3 wherein the yarns in the belt running direction in the layer adjacent to the layer of elastic material are nylon monofilaments or polyester monofilaments 0.25 to 0.6 mm in diameter, the yarns in the belt running direction in the layer next close to the layer of elastic material are textured yarns of 1000 to 4000 denier nylon multifilament or nylon or polyester spun yarns, and the yarns in the belt running direction in the layer farthest from the layer of elastic material are nylon monofilaments or polyester monofilaments 0.25 to 0.6 mm in diameter, and the number of the yarns in each layer is 5 to 12 per centimeter.
Claim 6
Dependent Claim
44 words
An endless belt according to anyone of Claims 1 to 4 wherein the yarns in the direction transversely across the belt running directions are nylon monofilaments 0.3 to 0.7 mm in diameter and the number of the yarns is 12 to 24 per centimeter.
Claim 7
Dependent Claim
56 words
An endless belt according to anyone of Claims 1 to 5 wherein the layer of elastic material is formed by applying polyurethane elastomer to one side of the woven base fabric and permetting it to penetrate into the base fabric to such an extent that it does not reach the other side of the base fabric.
Claim 8
Dependent Claim
31 words
An endless belt according to anyone of Claims 1 to 6 wherein the yarns which are exposed on the exposed side of the base fabric are coated with wearresis- tant film.
