Assembly to align the echelon side-edges of a stack of paper has suction pads

摘要

In a paper or carton handling assembly, a series of sheets is fed in echelon format to a collection point at which they form a stack held on a suction unit, and where the edges of the stacked sheets are then aligned on a carriage (3). The carriage (3) has suction pads (8) which can be moved relative to the suction plate (4) within the carriage (3).
