Abstract
An apparatus for forming consecutive groups of face-to-face stacked, flat articles includes an input conveyor for advancing the articles arranged in a flat-lying orientation and in a column of indeterminate length; a downwardly curving track arranged for receiving the articles from the input conveyor; a stock-forming device arranged for performing stacking steps by consecutively taking articles from the track and moving each article onto a trough into a face-to-face engagement with an outermost article of a group being under formation on the trough. There is provided a stepping motor connected to the stack-forming device for operating it in steps; a sensor arranged upstream of the stack-forming device responds to a passage of each article on the track. The sensor is connected to the stepping motor to operate it when the sensor responds. When the group has reached a predetermined number of articles or length, a mechanism discharges the group from the trough into a receptacle.
