Abstract
In the case of an apparatus for forming a stack of sheets comprising a brake means placed at (in terms of sheet motion) the leading edge of the stack and downstream from a sheet transport means, the brake means having at least one brake roller driven at a lower peripheral speed than the speed of transport of the sheets and a timed sheet nip member adapted to engage a sheet and move it towards the brake roller, one aim of the invention is to ensure reliable retardation and straightening of the sheets without damage to them. In order to attain this objective the brake means, whose sheet nip member or members is in the form of at least one segment able to be driven at a speed equal to the speed of the braking roller cooperating therewith when tripped by the sheet, is placed at the downstream end of at least one suction belt designed to receive the respective sheets from a sheet processing machine, and at least one blow tube is placed over the stack and downstream from the said brake roller, such blow tube, that is supplied with air under pressure, having at least one nozzle generally directed in the direction of sheet transport.
