ABSTRACT:
A method of, and apparatus for, feeding corrugated blanks from a stack in which the lowermost blank is advanced to processing machinery on a feed bed which comprises rollers mounted above a vacuum source in such manner as to enable the advancing blank to be held flat while minimizing friction between the advancing blank and the feed bed. In one preferred embodiment, a kicker feed bar is utilized which is depressed with respect to the rollers to enable the lowermost blank to be advanced while maintaining substantially the same vertical height in a flat plane until reaching the proximity of the processing machinery.
