Fabric Having a Sheet of Reinforcement Threads, and Awning Comprising Said Fabric

Abstract

A fabric includes two parallel selvages, and can be wound onto itself in at least one winding direction running parallel or perpendicular to said parallel selvages. The fabric is to be kept taut and includes a support layer that has a front face and a rear face. The fabric includes at least two sheets, i.e. a first sheet and a second sheet, one of which is arranged on top of the other and which consist of reinforcement threads, said sheets being arranged on the rear face, and the reinforcement threads extending at angles of 5 to 85° relative to the winding direction, with said angles being symmetrical in relation to the winding direction.

1 . A fabric comprising two parallel selvages, which can be wound onto itself in at least one winding direction running parallel or perpendicular to said parallel selvages, to be kept taut and comprising a support layer, said support layer has a front face and a rear face, wherein the fabric includes at least a first sheet and a second sheet, one of which is arranged on top of the other and which consist of reinforcement threads, said sheets being arranged on the rear face, the reinforcement threads extending at angles of 5° to 85° relative to the winding direction, said angles being symmetrical in relation to the winding direction. 
     
     
         2 . The fabric according to  claim 1 , wherein the support layer is a fabric, a non-woven fabric, a grille or a film. 
     
     
         3 . The fabric according to  claim 1 , wherein said sheets comprising reinforcement threads are sewn or glued to said support layer. 
     
     
         4 . The fabric according to  claim 1 , wherein the reinforcement threads of a sheet are not all contiguous. 
     
     
         5 . The fabric according to  claim 1 , wherein the reinforcement threads have a count between 50 dtex and 1,200 dtex. 
     
     
         6 . The fabric according to  claim 1 , wherein the fabric is coated on said front face and/or on said rear face. 
     
     
         7 . The fabric according to  claim 1 , further comprising two additional sheets of reinforcement threads including a third sheet and a fourth sheet, with said reinforcement threads extending at angles between 5° and 85° with said winding direction, said angles being symmetrical in relation to the winding direction. 
     
     
         8 . The fabric according to  claim 1 , wherein the reinforcement thread sheets present a different reinforcement thread density between sheets. 
     
     
         9 . The fabric according to  claim 1 , wherein said sheets comprise, independently, between 2 and 8 reinforcement threads per cm. 
     
     
         10 . The fabric according to  claim 1 , wherein said support layer is rectangular or trapezoidal in form. 
     
     
         11 . An awning comprising at least one fabric according to  claim 1 . 
     
     
         12 . An awning comprising at least two fabrics according to  claim 1 , wherein said fabrics are assembled by soldering then by calandering or by rabbet.
