摘要:
The present invention provides for an apparatus for treating a stack (10) of sheets of sheet material, comprising means (13) for moving the stack of sheets of sheet material towards first and second fold roller means (25), the fold roller means being arranged to assist with folding of the stack of sheets of sheet material, first and second clamping jaws (12) defining a gap (14) therebetween and arranged to be movable relative to each other to increase and decrease the gap for selective application of a clamping force a stack of sheets having passed between the fold roller means, wherein the first and second fold roller means are mounted in a manner allowing for an increase and decrease in separation and thus between a stack-guiding configuration and a stack compressing configuration.
