Abstract
A method and apparatus for piling a plurality of cut blanks of a flexible material in overlapped and shingled or stacked relationship. After being cut each blank is accelerated to increase its lineal speed to thereby produce a gap between the blank and an immediately succeeding blank. After acceleration, each blank is deflected, preferably by a plate, away from and out of its accelerated path of travel toward an underlying receiving surface such as a conveyor or platform. After being deflected, the trailing portion of each blank is displaced preferably by rotating cams so that when rapidly decelerated, an immediately succeeding blank passes into and is deposited in overlapping relationship with such blank. To deposit the blanks is stacked relationship with their leading edges substantially aligned, they are decelerated from their forward travel to a complete stop preferably by striking a positive stop. To deposit the blanks in shingled relationship with their leading edges spaced apart, they are rapidly decelerated to a relatively slow speed at which they continue to be advanced in their path of travel, preferably by a conveyor on which they are received.
