Auxiliary driving device for the transport of sheets of paper or cardboard

摘要

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.
