An auxiliary device for transporting of sheets of paper or cardboard arranged in a tilewise stream from a feeding station of a die-cutting press to the die-cutting station of the press includes a driving roller coupled with a rotary brush making up an assembly arranged between the lower section and the upper section of the feed table. The assembly has a pressure arrangement designed to apply the assembly on the upper surface of the stream of sheets. The drive of the rotary brush is obtained from the rotation of the driving roller by means of a toric ring mounted on a circumference of a cylindrical head of an axle for the rotary brush being received on a cylindrical surface formed in a recess of the driving roller. The amount of torque being transferred is obtained by adjusting the position of the rotary brush relative to the driving roller.
In an auxiliary driving device for the transport of sheets of paper or cardboard that are arranged tilewise in a stream from a feeding station of a die-cutting press to the die-cutting station of the press, said auxiliary driving device including a driving roller, a rotary brush, means for coupling the driving roller to the rotary brush to form an assembly arranged between a lower section and an upper section of a feeding table, said assembly including pressure means for biasing and urging the assembly onto an upper surface of the stream of sheets, the improvements comprising the means for coupling including a toric ring mounted on a circumference of a cylindrical head of an axle of the rotary brush, said toric ring being disposed in a circular recess of the driving roller, and means for adjusting the pressure between the ring and surface of the recess by moving the rotary brush relative to the driving roller.
