Abstract:
A buckle-plate folding station including a first folding roller, a pair of counter-rotating fold-forming rollers and an adjustable buckle-plate folding unit, and further comprising:a) means for detecting a sheet infeed at said folding unit and determining a corresponding moment in time,b) means for detecting a deflection of at least one of said pair of fold-forming rollers in forming a fold and determining a corresponding moment in time,c) means for determining a length of sheet fed between said determined moments in the between sheet infeed and deflection, andd) means for cantrolling and processing signals provided by said means for detecting said sheet infeed, signals provided by said means for detecting a deflection, and signals provided by said means for determining said fed sheet length to adjust buckle-plate length.
