Device for producing a fabric and fabric

Abstract

The invention relates to a device for producing a fabric, wherein, in each weaving step, a shed can be formed by means of warp threads, through which a weft thread can be led, and the weft thread can be pushed in the direction of a fabric edge by means of a reed. Here, a weft thread insertion device is provided, by means of which an angle of insertion of the weft thread and/or beating up the same at the edge of the fabric can be adjusted variably in relation to the weft thread. The invention further relates to such a fabric. According to the invention, the weft thread insertion device for adjusting the angle of insertion of the weft thread has at least one adjusting unit, which is coupled to the reed, wherein the adjusting unit comprises two piston-cylinder units, which are each coupled to one end of the reed.

1 . A device for producing a woven fabric, wherein in each weaving step a weaving shed through which a weft thread is insertable is configurable by means of warp threads, and the weft thread is displaceable in the direction of a woven-fabric periphery by means of a weaving reed, wherein a weft-insertion device by means of which an angle for insertion of a weft thread and/or for beating the latter up against the woven-fabric periphery in relation to the warp thread is variably adjustable is provided, wherein the weft-insertion device for adjusting the angle for insertion of the weft thread has at least one readjustment unit which is linked to the weaving reed, wherein the readjustment unit and the angle to be adjusted therewith are adjustable by means of an electric drive by way of a gear unit. 
     
     
         2 . The device as claimed in  claim 1 , wherein an angle of the weaving reed in relation to the warp threads is adjustable by means of the readjustment unit so as to be between 40° and 90°. 
     
     
         3 . The device as claimed in  claim 1 , wherein the readjustment unit comprises a retaining device which is displaceable in the direction of the progression of the warp threads. 
     
     
         4 . The device as claimed in  claim 1 , wherein the readjustment unit comprises two cylinder-and-piston units which are in each case linked to one end of the weaving reed. 
     
     
         5 . The device as claimed in  claim 1 , wherein the cylinder-and-piston unit is pneumatically activated. 
     
     
         6 . The device as claimed in  claim 1 , wherein the weft-insertion device and/or the readjustment unit are/is displaceable in the direction of the progression of the warp threads. 
     
     
         7 . The device as claimed in  claim 1 , wherein the weft-insertion device and/or the readjustment unit for actuation are/is connected to a control unit thereof. 
     
     
         8 . The device as claimed in  claim 1 , wherein a detection unit for positioning at least the readjustment unit in relation to the woven-fabric periphery is provided. 
     
     
         9 . The woven fabric which is produced by means of a device as claimed in  claim 1 , wherein the weft threads in relation to the warp threads run at an angle between 40° and 90°.
