Fabric for a machine for producing a fiber web

Abstract

A fabric for a machine that produces a fiber web, especially a paper-, board-, tissue- or pulp web. The fabric has a flat woven base material having a top side and a bottom side, two terminal ends separated in a machine direction. Folds are formed in the flat woven base material separated in the machine direction, whereby the two terminal ends are located under the bottom side surface. The two terminal ends are arranged adjacent to each other or they overlap each other. Seam loops are located at the folds. The novel fabric has at least one woven component, that is a multi-layer weave, especially a two-layer weave.

1 . A fabric for a machine for producing a fiber web, the fabric comprising:
 a flat woven base material having a top side and a bottom side, two terminal ends separated from one another in a machine direction;   folds formed in the flat woven base material, said folds being separated in the machine direction and said two terminal ends being located under the bottom side surface;   said two terminal ends being arranged adjacent one another or overlapping one another and said folds having seam loops located at said folds; and   at least one woven component formed as a multi-layer weave.   
     
     
         2 . The fabric according to  claim 1 , wherein said multi-layer weave is a two-layer weave. 
     
     
         3 . The fabric according to  claim 1 , wherein the machine is configured to produce a paper web, a board web, a tissue web or pulp web. 
     
     
         4 . The fabric according to  claim 1 , wherein said flat woven base material is a multi-layer weave. 
     
     
         5 . The fabric according to  claim 4 , wherein said flat woven base material is a two-layer weave. 
     
     
         6 . The fabric according to  claim 1 , which further comprises an insert located between said folds, said bottom side surface and said terminal ends arranged adjacent to one another. 
     
     
         7 . The fabric according to  claim 6 , wherein said at least one insert is a woven insert. 
     
     
         8 . The fabric according to  claim 6 , wherein said at least one woven insert is a multi-layer weave. 
     
     
         9 . The fabric according to  claim 8 , wherein said at least one woven insert is a two-layer weave. 
     
     
         10 . The fabric according to  claim 1 , wherein said two terminal ends are arranged adjacent one another or overlap one another in a region that is offset from a center between said folds. 
     
     
         11 . The fabric according to  claim 1 , wherein one or more cross direction yarns are removed from said flat woven base material at one of said folds or at both of said folds in order to form said seam loops. 
     
     
         12 . The fabric according to  claim 1 , which further comprises at least one layer of fibrous batt. 
     
     
         13 . The fabric according to  claim 1 , formed as a seamable fabric comprising only a single seam.
