Method for producing a woven fabric

Abstract

The invention relates to a method for producing a woven fabric by means of a device, wherein in one weaving step respectively one shed is formed by means of warp threads, through which shed a weft thread is introduced and the weft thread is pushed in the direction of a woven fabric edge by means of a weaving reed. An angle for entering a weft thread is variably adjusted by means of a weft thread entering device. According to the invention, the angle of the weft thread to be entered in relation to the warp threads is adjusted between 40° and 90° by means of an adjustment unit, wherein the weft thread entering device is positioned by means of an electric drive via a gear with respect to the predetermined angle.

1 . A method for producing a woven fabric by means of device, wherein in each weaving step a weaving shed through which a weft thread is inserted is formed by means of warp threads, and the weft thread is displaced in the direction of a woven-fabric periphery by means of a weaving reed, wherein by means of a weft-insertion device an angle for insertion of the weft thread is variably adjusted,
 wherein the angle for insertion of the weft thread in relation to the warp threads by means of a readjustment unit is adjusted between 40° and 90°, wherein the weft-insertion device in relation to the predetermined angle is positioned by means of an electric drive by way of a gear unit.   
     
     
         2 . The method as claimed in  claim 1 , wherein an angle for beating the weft thread against the woven-fabric periphery in relation to the warp thread is variably adjusted. 
     
     
         3 . The method as claimed in  claim 1 , wherein the readjustment unit is automatically displaced in the direction of the warp threads so as to depend on a length of the woven fabric. 
     
     
         4 . The method as claimed in  claim 1 , wherein a beating movement of the weaving reed against the woven-fabric periphery is generated by means of at least one cylinder-and-piston unit of the readjustment unit. 
     
     
         5 . The method as claimed in  claim 4 , wherein the cylinder-and-piston unit is pneumatically activated. 
     
     
         6 . The method as claimed in  claim 1 , wherein the weft-insertion device is displaced in the direction of the warp threads so as to depend on a length of the woven fabric. 
     
     
         7 . The method as claimed in  claim 1 , wherein the weft-insertion device and/or the readjustment unit are/is actuated by means of a control unit. 
     
     
         8 . The method as claimed in  claim 1 , wherein automatic positioning of the readjustment unit in relation to the woven-fabric periphery is performed by means of signals detected by a detection unit. 
     
     
         9 . A woven fabric which is produced by means of a method as claimed in  claim 1 , wherein the weft threads in relation to the warp threads run at an angle between 40° and 90°.
