Abstract

In a flat gathering binding system it is necessary to use a cover breaker to apply pressure to the book and cover to form a sharp square fold on each side. A cover breaker control system includes a motor (108) which is coupled to a cover breaker carriage for varying the relative position of first and second movable cover breaker plates (104,106) which are used to apply the pressure. A controller calculates the difference between book thickness which the plates are set for and a desired thickness, and is operable to vary the relative positioning by a distance corresponding to this difference so that when the plates are driven to break the cover they are spaced a distance apart according to the desired thickness.
