Patent ID: 6883409

Claim:
An apparatus for cross-cutting a cardboard web, comprising: a web feeder for feeding a cardboard web to the apparatus; a cross-cutter device positioned to receive said web from said feeder and provided with two blade drums having transverse blades for shearing said web across a width thereof into a succession of sheets; and a sheet transport device downstream of said cross-cutter device in a direction of displacement of said web and said sheets and including: a lower belt conveyor having an upper pass extending between an upstream rerouting roller positioned to receive said sheets from said cross-cutter device and a downstream rerouting roller bounding a discharge gate, and a downwardly inclined pass beginning at said downstream rerouting roller and forming a conveyor of sheets in said discharge gate, said upper pass accelerating said sheets away from said cross-cutter device, and a brake downstream of said upper pass for slowing said sheets so that subsequent sheets overlap previous sheets to form a shingled series of said sheets, said brake being spaced from said downstream rerouting roller whereby said downstream rerouting roller and said upper pass free said sheets for travel over a path region in which said sheets are not engaged; a deflector for selectively deflecting a sheet to be discharged into said discharge gate; a further conveyor for displacing said shingled series of sheets in said direction of displacement; and a carriage shiftable in said direction of displacement, said lower belt conveyor, said brake and said deflector being mounted on said carriage, and a piston-and-cylinder unit connected with said carriage for displacing said carriage between an operating position close to said cross-cutter device and another position spaced away from said cross-cutter device.
