Method and apparatus for bottom folding and stacking tray

Abstract From the Canadian patent

A method and apparatus for bottom folding and stacking of continuous strip of pre-folded paper is disclosed in which a reciprocating frame having a pair of sets of transverse rollers defining a gap therebetween reciprocates within a stationary frame beneath a pair of spaced-apart edge guides. Each set of transverse rollers is journalled in the inner frame and has a belt thereon preferably affixed at both ends to its respective edge guide.
