Apparatus for receiving a continuous web of prefolded forms from a high-speed printer and stacking them refolded on a tray has brake means and feed rollers for the web, the brake means being applied intermittently to allow the folds to refold as the forms fall to the tray. Feeler fingers continuously sense the distance from the rollers to the stack top and control the automatic lowering of the tray as the stack builds up. The feed rollers have nylon hubs and rims connected by sponge rubber cores for minimum gripping of the web whatever its thickness. A modification has continuously applied brake means and rollers with a flatted perimetrical portion for rapid intermittent feeding of web to stack.
