A woven-fabric belt for a fibrous web machine includes longitudinal and cross threads forming crossing points, top and bottom sides and a seam segment. Each longitudinal thread has end segments with ends. A segment is formed by weaving end segments with cross threads. Some end segments follow a weaving path with the cross threads, along which an end segment forms floats on the sides in alternation in direction of the thread end and a float is disposed on the bottom side between two adjacent floats on the top side and vice versa. A last float before the thread end is formed on one side and the end segment switches from one side to the other following the last float before the thread end. The end segment is bonded to a cross thread at one thread crossing point in one float lying before the last float in the weaving path.

1. A woven-fabric belt for a machine producing or processing a fibrous web, the woven-fabric belt comprising: longitudinal threads and woven-fabric seam cross threads being interwoven and forming thread intersection points, mutually opposite upper and lower sides and a woven-fabric seam portion;each of said longitudinal threads having a length and two end-side longitudinal thread end portions with a respective thread end along said length;said woven-fabric seam portion being formed by interweaving said longitudinal thread end portions with said woven-fabric seam cross threads;at least some of said longitudinal thread end portions, upon interweaving with said woven-fabric cross threads, following a weaving path along which said respective longitudinal thread end portion in a direction toward said thread end thereof repeatedly and alternatingly configuring floats on said upper side and on the lower side;one of said floats on said lower side being disposed between two directly adjacent floats on said upper side and one of said floats on said upper side being disposed between two directly adjacent floats on said lower side;said floats including a last float before said thread end in said weaving path being formed on one of said upper and lower sides;said longitudinal thread end portion, subsequent to said last float before said thread end, changing from one of said upper and lower sides to the other of said upper and lower sides;said longitudinal thread end portion, at least at one of said thread intersection points, being connected in a materially integral manner to one of said woven-fabric cross threads;said at least one thread intersection point, having said longitudinal thread end portion connected in a materially integral manner to said one woven-fabric seam cross thread, being disposed in at least one of said floats lying before said last float in said weaving path; andat least one of said at least some longitudinal threads or at least some woven-fabric seam cross threads have a flattened cross-sectional shape along a complete length thereof. 2. The woven-fabric belt according to claim 1, wherein in said weaving path of said at least some longitudinal thread end portions, said at least one thread intersection point at which said respective longitudinal thread end portion is connected in a materially integral manner to a woven-fabric seam cross thread, is disposed in at least one of said floats being one of six or one of four floats directly preceding said last float. 3. The woven-fabric belt according to claim 1, wherein in said weaving path of said at least some longitudinal thread end portions, said at least one thread intersection point at which said respective longitudinal thread end portion is connected in a materially integral manner to a woven-fabric seam cross thread, is disposed in a float being a penultimate float directly preceding said last float. 4. The woven-fabric belt according to claim 1, wherein floats of dissimilar lengths are formed in said weaving path of said at least some longitudinal thread end portions, and said at least one thread intersection point, at which said respective longitudinal thread end portion is connected in a materially integral manner to a woven-fabric seam cross thread, is disposed in a float having a shorter length than other floats. 5. The woven-fabric belt according to claim 1, wherein at least one of said further woven-fabric seam cross threads, being connected in a materially integral manner to said longitudinal thread end portion at said thread intersection point, is disposed in said last float. 6. The woven-fabric belt according to claim 1, wherein said at least some longitudinal threads have a flattened cross-sectional shape and said woven-fabric cross threads have a circular cross-sectional shape. 7. The woven-fabric belt according to claim 6, wherein at least one of said longitudinal threads or said woven-fabric seam cross threads include a first thread type and a second thread type, said thread types are formed of different materials, and said material of said first thread type absorbs more radiation energy than said material of said second thread type. 8. The woven-fabric belt according to claim 7, wherein said woven-fabric seam cross threads, being connected in a materially integral manner to said longitudinal thread end portions at said thread intersection points, are threads of said first thread type, and said longitudinal threads and remaining cross threads are threads of said second thread type. 9. The woven-fabric belt according to claim 1, wherein said materially integral connection has characteristic of being effected by an influence of radiation energy or laser radiation energy. 10. The woven-fabric belt according to claim 1, wherein the woven-fabric belt is formed by at least one of only one system of longitudinal threads or only one system of cross threads. 11. The woven-fabric belt according to claim 1, wherein: the woven-fabric belt is an endless woven-fabric belt formed by a flat-woven main woven-fabric portion and said woven-fabric seam portion,said main woven-fabric portion is formed by said interwoven longitudinal threads and main woven-fabric cross threads;said main woven-fabric portion has a longitudinal extent being delimited by first and second face-side portion ends;at least some of said longitudinal threads have at least one of: first longitudinal thread end portions with a first thread end protruding beyond said first face-side portion end in the MD direction, orsecond longitudinal thread end portions with a second thread end protruding beyond said second face-side portion end; andsaid face-side portion ends are interconnected by said woven-fabric seam portion being formed by collecting and interweaving said first and second longitudinal thread end portions with said woven-fabric seam cross threads. 12. The woven-fabric belt according to claim 11, wherein the woven-fabric belt is endless and said first and second longitudinal thread end portions are each gathered in pairs to form meeting points. 13. The woven-fabric belt according to claim 12, wherein at least some of said first and second longitudinal thread end portions being gathered in pairs are collectively interwoven with one or a plurality of woven-fabric seam cross threads. 14. The woven-fabric belt according to claim 12, wherein at least some of said first and second longitudinal thread end portions being gathered in pairs are collectively interwoven with at least one woven-fabric seam cross thread, and said at least one collectively interwoven woven-fabric seam cross thread is disposed in said weaving path of said first longitudinal thread portion and in said weaving path of said second longitudinal thread portion in said last float. 15. The woven-fabric belt according to claim 12, wherein at least some of said first and second longitudinal thread end portions being gathered in pairs are collectively interwoven with at most six directly adjacent woven-fabric seam cross threads, said collectively interwoven woven-fabric seam cross threads are disposed in said weaving path of said first longitudinal thread end portion in said last float and in said float directly preceding said last float, and said collectively interwoven woven-fabric seam cross threads are disposed in said weaving path of said second longitudinal thread end portion in said last float and in said float directly preceding said last float. 16. The woven-fabric belt according to claim 1, which further comprises at least one of: woven-fabric seam cross threads interconnecting said first longitudinal thread end portions in a materially integral manner for dissimilar first longitudinal thread end portions provided by dissimilar woven-fabric seam cross threads, orwoven-fabric seam cross threads interconnecting said second longitudinal thread end portions in a materially integral manner for dissimilar second longitudinal thread end portions provided by dissimilar woven-fabric seam cross threads.
