Abstract

A transport belt, in particular an endless suction belt, for conveying sheets to a press, can be driven, deflected over at least two rollers, and guided over a conveyor table. The lateral edges of the transport belt have a high degree of roughness or a structure, in order that no constant sharp edge is produced by the edges of the transport belt curving upward in the deflection region.

Claims

exact text as granted — not AI-modified
1 . In a transport belt for conveying sheets, configured to be driven, deflected over at least two rollers, and guided over a conveyor table, the improvement which comprises: the transport belt having lateral edges formed with an edge structure.  
     
     
         2 . The transport belt according to  claim 1  configured as an endless suction belt.  
     
     
         3 . The transport belt according to  claim 1 , wherein the edge structure is a roughness with a laterally extending amplitude of RZ>1 millimeter.  
     
     
         4 . The transport belt according to  claim 1 , wherein the edge structure is has a zigzag shape.  
     
     
         5 . The transport belt according to  claim 1 , wherein the edge structure has a sinusoidal shape.  
     
     
         6 . The transport belt according to  claim 1 , wherein the edge structure has a square wave shape.  
     
     
         7 . The transport belt according to  claim 1 , wherein the edge structure has a sawtooth shape.  
     
     
         8 . The transport belt according to  claim 1 , wherein the edge structure has a meandering shape.  
     
     
         9 . The transport belt according to  claim 1 , wherein the edges of the belt are formed with a chamfer.  
     
     
         10 . The transport belt according to  claim 1 , wherein the edges of the belt are formed with a rounding.  
     
     
         11 . A conveying table for conveying sheets to a sheet-processing machine, comprising: 
 a suction box;    at least two deflection rollers; and    an endless transport belt guided over said suction box and deflected about said deflection rollers, said transport belt being a suction belt with lateral edges formed with an edge structure.
